Certified Ambulatory Perianesthesia Nurse (CAPA) — Questions and Answers

Question 1: Which action by the discharging nurse BEST demonstrates adherence to the 'teach-back' method?

Reading all discharge instructions aloud to the patient and escort
Providing written instructions and asking if the patient has questions
Having the patient sign the instruction sheet confirming understanding
Asking the patient to repeat back key instructions in their own words (Correct answer)

Correct answer: Asking the patient to repeat back key instructions in their own words

Teach-back requires the patient to demonstrate understanding by restating information in their own words, not just acknowledging receipt of instructions.

Question 2: Which intervention is MOST appropriate as a FIRST response to emergence agitation in the PACU?

Administer a propofol bolus to re-sedate
Reorient the patient, reduce stimuli, dim lights, and ensure safety (Correct answer)
Administer haloperidol 5 mg IV immediately
Transfer to the ICU for closer monitoring

Correct answer: Reorient the patient, reduce stimuli, dim lights, and ensure safety

Non-pharmacological interventions — reorientation, reducing environmental stimuli, and ensuring patient safety — are the first-line approach before pharmacological sedation is considered.

Question 3: Which of the following is an appropriate non-pharmacologic nursing measure to reduce PONV in the PACU?

Encouraging deep breathing exercises every 2 hours
Providing early carbohydrate-rich oral intake to stabilize blood glucose
Minimizing unnecessary movement and maintaining a calm environment (Correct answer)
Keeping the head of bed flat to reduce vestibular stimulation

Correct answer: Minimizing unnecessary movement and maintaining a calm environment

Minimizing unnecessary patient movement and maintaining a quiet, calm environment reduces vestibular and sensory triggers for nausea and vomiting.

Question 4: What role does continuous improvement play in evidence-based practice in pacu for CAPA certified professionals?

It focuses exclusively on cost reduction
It drives ongoing enhancement of practices, processes, and outcomes through systematic evaluation (Correct answer)
It applies only to new professionals in their first year
It is optional and only necessary during certification renewal

Correct answer: It drives ongoing enhancement of practices, processes, and outcomes through systematic evaluation

Continuous improvement is fundamental to professional practice in evidence-based practice in pacu, involving regular evaluation, feedback integration, and process enhancement to maintain high standards.

Question 5: When assessing a patient's readiness to transfer from Phase I to Phase II PACU, which criterion is MOST important to verify first?

The patient has voided at least 30 mL of urine
The patient's pain is rated 0/10
The patient can state their name and date of birth correctly
The patient's airway is patent and ventilation is adequate with a stable SpO2 (Correct answer)

Correct answer: The patient's airway is patent and ventilation is adequate with a stable SpO2

Airway patency and adequate ventilation are the most critical safety parameters before any PACU phase transition.

Question 6: A nurse prepares to perform a modified jaw thrust on an unconscious post-anesthesia patient. Which technique is CORRECT?

Place thumbs on the chin and push the jaw forward while hyperextending the neck
Grip the lower teeth with fingers and pull the jaw anteriorly
Apply bilateral pressure over the zygomatic arches while tilting the head back
Position fingers behind the angle of the mandible and lift forward without moving the neck (Correct answer)

Correct answer: Position fingers behind the angle of the mandible and lift forward without moving the neck

The jaw thrust is performed by positioning fingers behind the angle of the mandible and lifting anteriorly, which opens the airway while maintaining cervical spine alignment.

Question 7: A 9-year-old weighing 30 kg requires morphine for post-op pain. What is the appropriate IV dose range?

0.01–0.02 mg/kg (0.3–0.6 mg)
0.2–0.4 mg/kg (6–12 mg)
1–2 mg flat dose regardless of weight
0.05–0.1 mg/kg (1.5–3 mg) (Correct answer)

Correct answer: 0.05–0.1 mg/kg (1.5–3 mg)

The standard pediatric IV morphine dose is 0.05–0.1 mg/kg, giving 1.5–3 mg for a 30 kg child, titrated to effect.

Question 8: A patient in the PACU after laparoscopic cholecystectomy has an SpO2 of 91% on 2L nasal cannula. The FIRST nursing intervention should be:

Increase oxygen flow to 4L via nasal cannula
Notify the anesthesia provider immediately
Apply a non-rebreather mask at 15L/min
Stimulate the patient and encourage deep breathing (Correct answer)

Correct answer: Stimulate the patient and encourage deep breathing

Stimulating the patient and encouraging deep breathing addresses the most common cause of hypoxemia in PACU — residual anesthetic-induced hypoventilation.

Question 9: In the context of ambulatory regional anesthesia recovery, what does the term 'fast-track recovery' mean?

Administering reversal agents to accelerate block resolution
Bypassing phase I PACU and moving directly to phase II recovery when criteria are met (Correct answer)
Using light sedation instead of general anesthesia to avoid PACU entirely
Reducing the recovery room stay to less than 30 minutes for all patients

Correct answer: Bypassing phase I PACU and moving directly to phase II recovery when criteria are met

Fast-track recovery allows patients who meet specific criteria (stable vitals, adequate pain control, no complications) to bypass phase I PACU and go directly to phase II, reducing recovery time.

Question 10: Preoperative warming of ambulatory surgery patients for at least 30 minutes primarily reduces intraoperative hypothermia by:

Increasing metabolic heat production
Preventing anesthetic-induced vasodilation
Elevating baseline core temperature above 37°C
Reducing the core-to-peripheral temperature redistribution gradient (Correct answer)

Correct answer: Reducing the core-to-peripheral temperature redistribution gradient

Preoperative warming reduces the core-to-peripheral temperature gradient, minimizing the redistribution hypothermia that occurs when anesthesia causes peripheral vasodilation.

Question 11: A PACU patient who received a bupivacaine femoral nerve block develops sudden seizures and progressive QRS widening on the monitor. The nurse should FIRST:

Administer phenytoin IV for seizure control
Activate the LAST protocol and prepare 20% lipid emulsion (Correct answer)
Administer amiodarone IV for the wide-complex rhythm
Call for the MH cart and begin cooling measures

Correct answer: Activate the LAST protocol and prepare 20% lipid emulsion

Sudden seizures followed by cardiac conduction abnormalities in a patient who received a bupivacaine block are classic LAST presentation, requiring immediate LAST protocol activation including intralipid.

Question 12: A patient undergoing preoperative evaluation reports a prior adverse reaction to anesthesia described as 'waking up during surgery.' Which documentation is MOST critical to obtain?

Cardiology clearance
Pulmonary function tests
Baseline serum creatinine levels
Prior anesthesia records detailing agents used and dosing (Correct answer)

Correct answer: Prior anesthesia records detailing agents used and dosing

Prior anesthesia records are essential to identify agents used and determine if the reaction was awareness under anesthesia, guiding the anesthesia plan.

Question 13: Which of the following patients is at HIGHEST risk for postoperative pulmonary complications in Phase I PACU?

A 50-year-old ASA II patient after knee arthroscopy under spinal anesthesia
A 42-year-old after shoulder arthroplasty under interscalene nerve block with sedation
A 68-year-old with COPD after a 3-hour open abdominal procedure under general anesthesia (Correct answer)
A 35-year-old non-smoker after a 45-minute laparoscopic procedure under general anesthesia

Correct answer: A 68-year-old with COPD after a 3-hour open abdominal procedure under general anesthesia

Advanced age, pre-existing pulmonary disease, longer operative duration, and upper abdominal surgery under general anesthesia compound the risk for postoperative pulmonary complications.

Question 14: A 68-year-old patient is ready for discharge but lives alone. Which action is MOST appropriate?

Delay discharge until a responsible adult escort is arranged (Correct answer)
Discharge the patient with a written phone number for the unit
Discharge and schedule a same-day phone follow-up
Call a taxi and provide the driver with discharge instructions

Correct answer: Delay discharge until a responsible adult escort is arranged

A responsible adult escort and caregiver are mandatory for ambulatory surgery discharge; living alone without one contraindicates immediate discharge.

Question 15: Post-tonsillectomy hemorrhage most commonly occurs within which time frame in the ambulatory setting?

First 2 hours in PACU
5–10 days postoperatively (Correct answer)
More than 2 weeks postoperatively
24–48 hours postoperatively

Correct answer: 5–10 days postoperatively

Secondary post-tonsillectomy hemorrhage peaks between days 5–10 when the fibrin eschar separates, and patients may present to ambulatory centers during this period.

Question 16: The CAPA nurse uses motivational interviewing techniques primarily to:

Reduce the time spent on discharge teaching
Convince patients to comply with discharge instructions
Document patient readiness for discharge
Facilitate patient-centered conversations that support behavior change (Correct answer)

Correct answer: Facilitate patient-centered conversations that support behavior change

Motivational interviewing is a patient-centered communication technique used to explore ambivalence and support patients in making positive health decisions.

Question 17: A patient exhibits confusion, tachycardia, and hypertension 1 hour after receiving scopolamine patch preoperatively. Which condition is most likely?

Anticholinergic toxidrome (Correct answer)
Emergence delirium
Malignant hyperthermia
Serotonin syndrome

Correct answer: Anticholinergic toxidrome

Scopolamine, an anticholinergic, can cause confusion, tachycardia, dry skin, and urinary retention — classic anticholinergic toxidrome.

Question 18: Which statement by a preoperative patient MOST indicates the need for additional psychological support?

'I prefer to have my family present during recovery.'
'I feel very nervous and I have a bad feeling about this surgery.' (Correct answer)
'I've had surgery before so I know what to expect.'
'I want to know all my discharge instructions before I go.'

Correct answer: 'I feel very nervous and I have a bad feeling about this surgery.'

Expressions of dread or 'bad feelings' about surgery may indicate significant preoperative anxiety that warrants additional support and assessment.

Question 19: A patient reports taking herbal supplements including St. John's Wort. Why is this information relevant to discharge planning?

Herbal supplements are irrelevant in the ambulatory surgery setting
It should be documented only for future anesthesia planning
The patient should stop all supplements immediately upon discharge
It may interact with discharge analgesics and affect recovery at home (Correct answer)

Correct answer: It may interact with discharge analgesics and affect recovery at home

St. John's Wort induces CYP enzymes and interacts with many medications including opioids, requiring medication reconciliation before discharge.

Question 20: Which condition is a contraindication to same-day discharge after ambulatory surgery in a former premature infant?

Presence of a parent or caregiver at home
Weight less than 10 kg at the time of surgery
Postconceptual age less than 60 weeks (Correct answer)
History of neonatal jaundice

Correct answer: Postconceptual age less than 60 weeks

Former premature infants with postconceptual age under 60 weeks are at high risk for post-anesthetic apnea and require overnight monitoring, making same-day discharge unsafe.

Question 21: Which preoperative laboratory test is considered routine for a healthy 25-year-old male scheduled for arthroscopic knee surgery?

Coagulation studies
Basic metabolic panel
Complete blood count
No routine labs are indicated (Correct answer)

Correct answer: No routine labs are indicated

Evidence-based guidelines indicate that routine preoperative laboratory testing is not indicated for healthy patients undergoing minor procedures.

Question 22: When a patient reports severe anxiety about a previously traumatic healthcare experience, the CAPA nurse's BEST approach is to:

Proceed with standard care without modifications
Refer all care decisions to the anesthesiologist
Ask the patient to describe their past experience and incorporate preferences into their care plan (Correct answer)
Avoid acknowledging the past trauma to prevent re-traumatization

Correct answer: Ask the patient to describe their past experience and incorporate preferences into their care plan

Acknowledging past trauma and incorporating patient preferences into care planning is central to trauma-informed, patient-centered perianesthesia nursing.

Question 23: When using the Modified Aldrete Score for Phase I PACU discharge, which criterion is scored from 0 to 2?

Pain level
Activity level (Correct answer)
Nausea severity
Temperature

Correct answer: Activity level

The Modified Aldrete Score evaluates activity, respiration, circulation, consciousness, and oxygen saturation, each scored 0–2.

Question 24: Which finding in a patient 90 minutes post-laparoscopic procedure warrants CONTINUED Phase I monitoring rather than Phase II transfer?

Respiratory rate of 16 breaths per minute
Blood pressure 148/88 vs. baseline 140/82
Oxygen saturation 89% requiring supplemental oxygen (Correct answer)
Mild throat discomfort after LMA removal

Correct answer: Oxygen saturation 89% requiring supplemental oxygen

SpO2 of 89% requiring supplemental oxygen indicates respiratory compromise requiring continued Phase I monitoring and intervention.

Question 25: A quality improvement team analyzes PACU unplanned admission rates. Which EBP step does this represent?

Formulating a PICO question
Identifying a clinical problem or trigger (Correct answer)
Appraising the evidence
Translating evidence into practice

Correct answer: Identifying a clinical problem or trigger

Analyzing outcome data to identify a problem is the first step in EBP, representing the problem identification or trigger phase.

Question 26: A patient undergoing monitored anesthesia care (MAC) receives dexmedetomidine intraoperatively. Which PACU assessment finding is most expected?

Nausea and vomiting
Bradycardia and sedation without respiratory depression (Correct answer)
Prolonged neuromuscular blockade
Hypertension and tachycardia

Correct answer: Bradycardia and sedation without respiratory depression

Dexmedetomidine causes alpha-2 mediated sedation and analgesia with bradycardia but preserves respiratory drive, distinguishing it from opioids.

Question 27: A patient receiving a continuous peripheral nerve block infusion at home calls the ambulatory surgery unit reporting that the catheter has dislodged. The nurse's BEST response is:

Reassure the patient that the block medication is already absorbed and no further action is needed
Advise the patient to double the oral analgesic dose to compensate for lost block
Instruct the patient to reinsert the catheter and restart the pump
Tell the patient to stop the pump, secure the site, and come to the facility for evaluation (Correct answer)

Correct answer: Tell the patient to stop the pump, secure the site, and come to the facility for evaluation

A dislodged catheter requires the patient to stop the infusion and return for evaluation, as reinsertion at home is not appropriate and additional local anesthetic may cause pooling or toxicity.

Question 28: According to SAMBA consensus guidelines, which Apfel score threshold typically warrants two-agent prophylaxis?

Score of 2 (Correct answer)
Prophylaxis is only warranted when score is 4
Score of 3-4
Score of 1

Correct answer: Score of 2

SAMBA guidelines recommend one antiemetic for Apfel score 1, two agents for score 2, and multimodal triple or quadruple therapy for scores 3-4.

Question 29: Which statement about nitrous oxide and PONV is accurate?

Nitrous oxide has no clinically significant effect on PONV incidence
Nitrous oxide only increases PONV in patients with a prior history of motion sickness
Nitrous oxide increases PONV risk by distending the bowel and stimulating the middle ear (Correct answer)
Nitrous oxide reduces PONV by providing analgesia and lowering volatile agent requirements

Correct answer: Nitrous oxide increases PONV risk by distending the bowel and stimulating the middle ear

Nitrous oxide increases PONV through bowel distension, middle ear pressure changes, and direct stimulation of the chemoreceptor trigger zone.

Question 30: Which of the following is a known triggering agent for malignant hyperthermia in susceptible individuals?

Propofol
Nitrous oxide
Ketamine
Succinylcholine (Correct answer)

Correct answer: Succinylcholine

Succinylcholine, along with volatile halogenated anesthetic agents, is a known triggering agent for MH in genetically susceptible individuals.

Question 31: Which discharge criterion specifically addresses readiness for home after ambulatory anesthesia in a pediatric patient?

Ability to tolerate a full meal without nausea
Return to baseline mental status and ability to ambulate independently
Modified Aldrete score ≥9 or PADSS ≥18 with stable vital signs (Correct answer)
Complete resolution of any sedation with no drowsiness

Correct answer: Modified Aldrete score ≥9 or PADSS ≥18 with stable vital signs

Most ambulatory centers use a Modified Aldrete score ≥9 or PADSS ≥18 as objective discharge criteria, combined with clinical assessment of the child.

Question 32: Which patient factor increases the minimum score required on a PACU scoring system before discharge to Phase II?

Presence of a responsible adult escort
Chronic opioid use
Difficult airway history (Correct answer)
History of hypertension

Correct answer: Difficult airway history

Patients with a history of difficult airway require closer airway monitoring and may require higher discharge thresholds due to risk of rebound obstruction.

Question 33: A patient undergoing gynecologic laparoscopy begins vomiting in Phase I PACU. She received ondansetron and dexamethasone intraoperatively. Which rescue agent acts via a different mechanism than both prophylactic drugs?

Repeat ondansetron 4 mg IV
Prochlorperazine 10 mg IV (Correct answer)
Repeat dexamethasone 4 mg IV
Granisetron 1 mg IV

Correct answer: Prochlorperazine 10 mg IV

Prochlorperazine is a phenothiazine/dopamine antagonist, offering a different mechanism from the serotonin antagonist and corticosteroid already used.

Question 34: Which medication class is most commonly used for acute postoperative pain?

Laxatives
Antihistamines
Antibiotics
Opioids (Correct answer)

Correct answer: Opioids

Opioids like morphine or fentanyl are typically used for managing moderate to severe postoperative pain.

Question 35: Why is continuous pulse oximetry important in the PACU?

Monitors oxygen saturation (Correct answer)
Calculates glucose levels
Measures blood pressure
Checks hydration status

Correct answer: Monitors oxygen saturation

Continuous pulse oximetry detects changes in oxygen saturation early, allowing timely interventions.

Question 36: Which intervention is MOST appropriate for a postoperative patient with a systolic BP of 190 mmHg and headache?

Place patient in Trendelenburg position
Administer an additional dose of opioid analgesic
Reassure the patient and recheck in 1 hour
Administer prescribed antihypertensive and notify the provider (Correct answer)

Correct answer: Administer prescribed antihypertensive and notify the provider

Hypertension with headache post-operatively requires antihypertensive treatment per order and provider notification to prevent cerebrovascular complications.

Question 37: A patient recovering in Phase I PACU after laparoscopic cholecystectomy develops right shoulder pain. The nurse understands this is most likely caused by:

Myocardial ischemia radiating to the shoulder
Referred pain from residual diaphragmatic irritation due to CO2 insufflation (Correct answer)
Positioning injury to the brachial plexus during surgery
Rotator cuff strain from intraoperative positioning

Correct answer: Referred pain from residual diaphragmatic irritation due to CO2 insufflation

Residual CO2 from laparoscopic insufflation irritates the diaphragm, causing referred phrenic nerve pain perceived in the ipsilateral shoulder.

Question 38: Which patient factor MOST significantly increases the risk of pulmonary aspiration in the perianesthesia period?

Female sex and obesity combined
Age greater than 65 years
Use of regional anesthesia technique
History of GERD combined with inadequate preoperative fasting (Correct answer)

Correct answer: History of GERD combined with inadequate preoperative fasting

GERD increases gastric acid presence and inadequate fasting increases gastric volume, together significantly elevating the risk of regurgitation and aspiration.

Question 39: How should CAPA professionals handle confidential information related to thermoregulation & fluid management?

Delete all records after project completion
Follow established protocols for data protection, access control, and disclosure in accordance with applicable regulations (Correct answer)
Share freely with all colleagues for transparency
Store information without any security measures

Correct answer: Follow established protocols for data protection, access control, and disclosure in accordance with applicable regulations

Confidential information must be handled according to established protocols, regulatory requirements, and professional ethics standards, including proper access control and disclosure procedures.

Question 40: An evidence-based practice protocol recommends early ambulation post-PACU discharge. Which outcome does this primarily target?

Reduction of incisional pain
Reduction of surgical site infection
Improvement of anesthetic elimination
Prevention of deep vein thrombosis and pulmonary embolism (Correct answer)

Correct answer: Prevention of deep vein thrombosis and pulmonary embolism

Early ambulation is evidence-based for reducing venous stasis and the risk of DVT and PE in postoperative patients.

Question 41: In the context of CAPA certification, what is the most important consideration when implementing regional anesthesia recovery care?

Ensuring alignment with established standards, stakeholder needs, and best practices (Correct answer)
Minimizing documentation to save time
Completing implementation as quickly as possible regardless of quality
Delegating all responsibilities to junior staff

Correct answer: Ensuring alignment with established standards, stakeholder needs, and best practices

When implementing regional anesthesia recovery care, CAPA professionals must ensure alignment with industry standards and stakeholder needs. Hasty implementation without proper planning often leads to compliance issues and suboptimal outcomes.

Question 42: A post-anesthesia patient is receiving oxygen via face mask at 8L/min with an SpO2 of 95%. The nurse notes the reservoir bag on the partial rebreather mask deflates completely with each breath. The CORRECT action is:

Place the patient on high-flow nasal cannula instead
Document the finding as normal mask function
Decrease oxygen flow to 4L/min
Switch to a non-rebreather mask and increase flow (Correct answer)

Correct answer: Switch to a non-rebreather mask and increase flow

Complete deflation of the reservoir bag indicates flow is insufficient to meet the patient's inspiratory demand; switching to a non-rebreather mask with higher flow maintains FiO2 delivery.

Question 43: In the PACU, orthostatic hypotension is BEST detected by:

Measuring BP in supine and then sitting/standing positions (Correct answer)
Checking capillary refill time
Monitoring continuous ECG
Palpating peripheral pulses

Correct answer: Measuring BP in supine and then sitting/standing positions

Orthostatic hypotension is defined as a significant drop in blood pressure when moving from supine to upright, requiring positional BP measurements.

Question 44: Which of the following best describes a key competency required for evidence-based practice in pacu in CAPA practice?

Reliance on a single methodology for all situations
Memorization of all relevant regulations without understanding context
The ability to work independently without any oversight
Strong analytical skills combined with effective communication and ethical judgment (Correct answer)

Correct answer: Strong analytical skills combined with effective communication and ethical judgment

CAPA professionals working in evidence-based practice in pacu need analytical skills to assess situations, communication skills to convey findings, and ethical judgment to make sound decisions.

Question 45: In which situation would a perianesthesia nurse be JUSTIFIED in contacting the surgeon before discharging a patient?

Patient requests a follow-up appointment in two weeks
Mild incisional discomfort rated 3/10 controlled with ibuprofen
Nausea that resolved after one dose of ondansetron
Unexpected drainage saturating the surgical dressing within 30 minutes (Correct answer)

Correct answer: Unexpected drainage saturating the surgical dressing within 30 minutes

Rapidly saturating surgical dressings suggest active bleeding requiring immediate surgical evaluation before the patient is discharged.

Question 46: Which of the following is the MOST appropriate pain criterion for ambulatory discharge readiness?

Complete absence of pain
Pain rated ≤7/10 regardless of medication
IV opioids required but patient is comfortable
Pain controlled with oral analgesics and rated ≤4/10 (Correct answer)

Correct answer: Pain controlled with oral analgesics and rated ≤4/10

Discharge pain criteria require pain manageable with oral analgesics and rated at or below a moderate level (≤4/10).

Question 47: Which of the following is a contraindication to nasopharyngeal airway insertion in a PACU patient?

Mild nasal congestion
Suspected basilar skull fracture (Correct answer)
Use of antiplatelet medication
Intact gag reflex

Correct answer: Suspected basilar skull fracture

Suspected basilar skull fracture is an absolute contraindication to nasopharyngeal airway insertion, as the tube could enter the cranial vault through a cribriform plate fracture.

Question 48: A patient with diabetes is prescribed dexamethasone for PONV prophylaxis. What is the primary concern the perianesthesia nurse should monitor for postoperatively?

Hypoglycemia due to increased insulin sensitivity
Hyperglycemia due to glucocorticoid-induced glucose elevation (Correct answer)
Fluid retention causing acute pulmonary edema
Adrenal suppression after a single prophylactic dose

Correct answer: Hyperglycemia due to glucocorticoid-induced glucose elevation

Dexamethasone, even as a single prophylactic dose, can cause significant postoperative hyperglycemia in diabetic patients and requires blood glucose monitoring.

Question 49: A PACU nurse is conducting a literature review on oxygen supplementation after ambulatory surgery. Which evidence-based finding most accurately reflects current guidelines?

All patients should receive supplemental oxygen for at least 2 hours post-op
Hyperoxia has no known adverse effects and should be used liberally
Oxygen therapy should be withheld to encourage deep breathing
Supplemental oxygen should be titrated to maintain SpO2 ≥92–95% per patient risk (Correct answer)

Correct answer: Supplemental oxygen should be titrated to maintain SpO2 ≥92–95% per patient risk

Evidence supports individualized, titrated oxygen therapy targeting SpO2 goals rather than routine prophylactic high-flow oxygen.

Question 50: A patient in the PACU is agitated and confused upon emergence. The nurse's FIRST priority is to:

Apply physical restraints
Administer a sedative immediately
Ask family members to leave the room
Ensure patient safety and assess for physiologic causes (Correct answer)

Correct answer: Ensure patient safety and assess for physiologic causes

Emergence delirium can result from physiologic causes like hypoxia or pain, which must be ruled out before other interventions.

Question 51: A nurse is caring for a patient with obstructive sleep apnea (OSA) post-procedure. Which positioning strategy is most appropriate during Phase I recovery?

Lateral decubitus or head-of-bed elevated 30–45 degrees (Correct answer)
Prone position
Supine with head of bed flat
Trendelenburg position

Correct answer: Lateral decubitus or head-of-bed elevated 30–45 degrees

Semi-upright or lateral positioning reduces upper airway collapse and improves oxygenation in OSA patients in the PACU.

Question 52: During fluid resuscitation in a 70 kg ambulatory surgery patient, which finding BEST indicates adequate volume replacement?

Heart rate decreasing from 110 to 88 bpm (Correct answer)
MAP of 55 mmHg
Capillary refill of 4 seconds
Urine output of 0.2 mL/kg/hr

Correct answer: Heart rate decreasing from 110 to 88 bpm

A decreasing heart rate toward normal range is a reliable clinical indicator of improving intravascular volume.

Question 53: A patient's escort arrives intoxicated and is unable to drive safely. What action should the perianesthesia nurse take?

Discharge the patient and call a cab
Administer naloxone to the escort to sober them up
Discharge the patient since a responsible adult is technically present
Contact a sober alternative escort or arrange safe transport; do not discharge to an intoxicated escort (Correct answer)

Correct answer: Contact a sober alternative escort or arrange safe transport; do not discharge to an intoxicated escort

An intoxicated escort cannot provide safe supervision or transport; discharge must be delayed until a responsible alternative is secured.

Question 54: During monitoring in Phase I PACU, a patient's ECG shows peaked T-waves and a widened QRS. Which electrolyte disturbance should be suspected?

Hyponatremia
Hypomagnesemia
Hypocalcemia
Hyperkalemia (Correct answer)

Correct answer: Hyperkalemia

Hyperkalemia classically produces peaked T-waves, widened QRS, and eventually sine-wave pattern, representing a life-threatening cardiac emergency.

Question 55: Which of the following increases a patient's fall risk after anesthesia?

Full mobility
Drowsiness and dizziness (Correct answer)
Clear fluids
IV access

Correct answer: Drowsiness and dizziness

Residual effects of sedatives and opioids impair coordination and increase fall risk.

Question 56: A patient receiving 3 liters of 0.9% normal saline develops a serum chloride of 115 mEq/L. The nurse should anticipate which complication?

Hyperchloremic metabolic acidosis (Correct answer)
Hypochloremic metabolic alkalosis
Respiratory alkalosis
Hypokalemic alkalosis

Correct answer: Hyperchloremic metabolic acidosis

Large volumes of normal saline cause hyperchloremic metabolic acidosis due to the high chloride load relative to bicarbonate.

Question 57: A PACU patient develops hypertension to 190/110 mmHg and complains of a headache. Which action should the nurse prioritize?

Administer PRN labetalol and document
Reassess in 15 minutes before notifying the physician
Perform a neurological assessment and notify the physician immediately (Correct answer)
Increase pain medication as hypertension may be pain-related

Correct answer: Perform a neurological assessment and notify the physician immediately

Severe hypertension with headache in the postoperative period may indicate hypertensive emergency or intracranial event, requiring immediate neurological assessment and physician notification.

Question 58: Which postoperative nausea and vomiting (PONV) score tool is commonly used to identify high-risk ambulatory surgery patients requiring prophylaxis?

Ramsay Sedation Scale
Apfel Simplified Risk Score (Correct answer)
PRST Score
Numeric Rating Scale

Correct answer: Apfel Simplified Risk Score

The Apfel Simplified Risk Score uses four predictors (female sex, non-smoker, history of PONV/motion sickness, opioid use) to stratify PONV risk.

Question 59: What role does continuous improvement play in nausea & vomiting prevention for CAPA certified professionals?

It applies only to new professionals in their first year
It is optional and only necessary during certification renewal
It drives ongoing enhancement of practices, processes, and outcomes through systematic evaluation (Correct answer)
It focuses exclusively on cost reduction

Correct answer: It drives ongoing enhancement of practices, processes, and outcomes through systematic evaluation

Continuous improvement is fundamental to professional practice in nausea & vomiting prevention, involving regular evaluation, feedback integration, and process enhancement to maintain high standards.

Question 60: What is the earliest and most sensitive sign of malignant hyperthermia (MH) in the perioperative setting?

Masseter muscle rigidity after succinylcholine
Tachycardia with hypertension
Unexplained rise in end-tidal CO2 (Correct answer)
Hyperthermia greater than 40°C

Correct answer: Unexplained rise in end-tidal CO2

An unexplained rise in end-tidal CO2 is the earliest and most sensitive indicator of MH, reflecting the hypermetabolic crisis before temperature elevation occurs.

Question 61: Which of the following is the MOST appropriate discharge instruction to provide to a Phase II patient after ambulatory surgery with general anesthesia?

You may drink alcohol in moderation this evening as long as you feel well
Do not make important legal or financial decisions for 24 hours due to lingering cognitive effects of anesthesia (Correct answer)
Resume all pre-operative medications including anticoagulants immediately
Resume normal diet immediately regardless of the type of surgery performed

Correct answer: Do not make important legal or financial decisions for 24 hours due to lingering cognitive effects of anesthesia

Residual cognitive effects of general anesthesia impair judgment and decision-making capacity for up to 24 hours, making important legal or financial decisions unsafe.

Question 62: In evidence-based PACU practice, which strategy best supports early discharge readiness in ambulatory surgical patients?

Requiring all patients to void before discharge regardless of procedure
Keeping patients until the effects of all reversal agents are verified
Using validated discharge scoring tools such as the Modified Aldrete or PADSS (Correct answer)
Delaying discharge until oral intake equals preoperative baseline

Correct answer: Using validated discharge scoring tools such as the Modified Aldrete or PADSS

Validated discharge scoring tools like the Modified Aldrete or PADSS provide objective, evidence-based criteria for safe discharge.

Question 63: A PACU patient develops complete laryngospasm after extubation. What is the FIRST-LINE nursing intervention?

Insert an oral airway immediately
Administer atropine IV to reduce secretions
Prepare for emergency surgical airway
Apply firm positive pressure with jaw thrust and 100% oxygen (Correct answer)

Correct answer: Apply firm positive pressure with jaw thrust and 100% oxygen

Sustained positive pressure with jaw thrust is the first-line intervention to mechanically break laryngospasm while providing 100% oxygen.

Question 64: A patient develops oliguria (20 mL/hr) in Phase II PACU after ambulatory surgery. What is the FIRST nursing action?

Insert a Foley catheter
Administer furosemide 20 mg IV
Assess fluid intake, blood pressure, and pain level (Correct answer)
Call the physician immediately for dialysis consult

Correct answer: Assess fluid intake, blood pressure, and pain level

Assessing the clinical picture — volume status, hemodynamics, and pain — helps differentiate pre-renal, renal, or obstructive causes before intervening.

Question 65: The CAPA nurse is caring for a patient with a history of PTSD undergoing ambulatory surgery. Which approach is MOST important?

Limit sensory input by keeping the room dark and silent
Avoid discussing the surgical experience
Increase sedation to prevent distress
Coordinate with the care team to use trauma-informed care principles (Correct answer)

Correct answer: Coordinate with the care team to use trauma-informed care principles

Trauma-informed care — including safety, trust, and choice — minimizes retraumatization and supports psychological safety in the perioperative setting.

Question 66: When assessing a patient for signs of LAST after a brachial plexus block, which neurological symptom would appear FIRST?

Respiratory arrest
Loss of consciousness
Generalized tonic-clonic seizure
Perioral numbness and metallic taste (Correct answer)

Correct answer: Perioral numbness and metallic taste

Early CNS excitatory signs of LAST include perioral numbness, metallic taste, and tinnitus before progression to seizures and cardiovascular collapse.

Question 67: A 7-year-old child is in Phase II recovery and reports nausea. The nurse notes no vomiting has occurred. What is the most appropriate initial intervention?

Administer ondansetron IV and encourage slow deep breathing (Correct answer)
Discharge the child immediately before vomiting occurs
Administer metoclopramide IM as first-line antiemetic
Hold all oral intake and reassess in 1 hour

Correct answer: Administer ondansetron IV and encourage slow deep breathing

Ondansetron is the first-line antiemetic in pediatric patients, and non-pharmacologic measures like deep breathing can also reduce nausea in the ambulatory setting.

Question 68: A patient in Phase II PACU who underwent inguinal hernia repair under spinal anesthesia complains of a severe bilateral positional headache that worsens when sitting up. This presentation is most consistent with:

Tension headache from intraoperative positioning
Hypoglycemia requiring blood glucose check and treatment
Hypertensive urgency requiring immediate blood pressure management
Post-dural puncture headache (PDPH) from cerebrospinal fluid leak (Correct answer)

Correct answer: Post-dural puncture headache (PDPH) from cerebrospinal fluid leak

Postural bilateral headache worse in upright position following spinal anesthesia is the classic presentation of post-dural puncture headache caused by CSF leak.

Question 69: A patient in Phase I recovery has respiratory rate of 8/min and SpO2 of 88% after receiving fentanyl and midazolam. After administering naloxone, the nurse should anticipate which complication?

Rebound hypoglycemia
Acute pulmonary edema and hypertensive crisis (Correct answer)
Prolonged sedation from residual opioid
Paradoxical bradycardia

Correct answer: Acute pulmonary edema and hypertensive crisis

Naloxone reversal of opioids can cause sudden catecholamine surge leading to acute pulmonary edema, severe hypertension, and cardiac arrhythmias.

Question 70: Which Aldrete score component specifically assesses a patient's ability to breathe deeply and cough freely?

Consciousness
Circulation
Respiration (Correct answer)
Activity

Correct answer: Respiration

The Respiration component of the Aldrete score evaluates the patient's ability to breathe deeply and cough effectively.

Question 71: A patient undergoing preoperative evaluation is found to have a hemoglobin of 7.8 g/dL. Which action is MOST appropriate for elective ambulatory surgery?

Postpone surgery and refer for anemia workup and treatment (Correct answer)
Transfuse two units of packed red blood cells preoperatively
Proceed; hemoglobin of 8 g/dL is required only for cardiac surgery
Administer IV iron infusion and proceed same day

Correct answer: Postpone surgery and refer for anemia workup and treatment

Significant anemia in an elective ambulatory patient warrants postponement to identify the cause and optimize hemoglobin before surgery.

Question 72: A pediatric patient is scheduled for tonsillectomy. Parents report the child had a runny nose and cough that resolved 10 days ago. What is the BEST course of action?

Proceed with surgery; the URI has resolved (Correct answer)
Administer prophylactic bronchodilators and proceed
Consult pulmonology before proceeding
Cancel surgery for 6 weeks

Correct answer: Proceed with surgery; the URI has resolved

A URI that has fully resolved for more than one to two weeks generally does not increase anesthetic risk and the procedure can proceed.

Question 73: Which finding in a postanesthesia patient would MOST warrant immediate intervention by the CAPA nurse?

SpO2 of 97% on room air
Heart rate of 78 bpm
Respiratory rate of 14 breaths/min
Blood pressure of 88/50 mmHg with diaphoresis (Correct answer)

Correct answer: Blood pressure of 88/50 mmHg with diaphoresis

Hypotension with diaphoresis signals hemodynamic instability requiring immediate assessment and intervention.

Question 74: After administering epinephrine for anaphylaxis, what is the NEXT priority intervention?

Establish large-bore IV access and begin aggressive fluid resuscitation (Correct answer)
Obtain a 12-lead ECG immediately
Apply high-flow oxygen via non-rebreather mask only
Administer diphenhydramine 50 mg IV

Correct answer: Establish large-bore IV access and begin aggressive fluid resuscitation

Following epinephrine, large-bore IV access and fluid resuscitation are critical to counteract the vasodilation and relative hypovolemia that characterize severe anaphylaxis.

Question 75: A patient in the PACU develops a new arrhythmia. The nurse's FIRST action should be to:

Assess the patient's hemodynamic status (Correct answer)
Administer antiarrhythmic medication
Notify the anesthesia provider immediately
Obtain a 12-lead ECG

Correct answer: Assess the patient's hemodynamic status

Patient assessment for hemodynamic stability must precede any intervention to determine urgency and appropriate response.

Question 76: Which vital sign parameter is typically required before ambulatory surgery discharge per Modified Aldrete criteria?

Blood pressure within 20 mmHg of preoperative baseline
Blood pressure within 20% of preoperative baseline (Correct answer)
Mean arterial pressure above 70 mmHg
Heart rate below 80 bpm

Correct answer: Blood pressure within 20% of preoperative baseline

The Modified Aldrete Score requires blood pressure within 20% (not 20 mmHg) of the preoperative baseline value to score maximum points.

Question 77: A patient returns from TURP under spinal anesthesia and develops sudden dyspnea with decreased breath sounds on the right and tracheal deviation to the left. The nurse should IMMEDIATELY:

Apply high-flow oxygen and elevate the head of bed 30 degrees
Prepare for emergency needle decompression of the right chest (Correct answer)
Obtain a STAT chest X-ray before any intervention
Administer bronchodilator via nebulizer

Correct answer: Prepare for emergency needle decompression of the right chest

Tracheal deviation away from the affected side combined with absent breath sounds indicates tension pneumothorax, a life-threatening emergency requiring immediate needle decompression.

Question 78: A patient is unable to void 4 hours after ambulatory urological surgery under spinal anesthesia. What is the MOST appropriate intervention?

Administer furosemide IV to stimulate voiding
Discharge the patient with bladder scan instructions for home
Perform bladder ultrasound; if >400 mL, perform straight catheterization (Correct answer)
Discharge immediately as voiding is not required post-spinal

Correct answer: Perform bladder ultrasound; if >400 mL, perform straight catheterization

Bladder scan followed by catheterization for volumes >400 mL prevents overdistension injury in patients with urinary retention after spinal anesthesia.

Question 79: What is the most effective way to measure success in pediatric perianesthesia nursing within CAPA professional practice?

Count only the number of activities completed
Compare only with industry averages without considering context
Use a combination of quantitative metrics, qualitative assessments, and stakeholder feedback aligned with defined objectives (Correct answer)
Rely solely on supervisor opinion

Correct answer: Use a combination of quantitative metrics, qualitative assessments, and stakeholder feedback aligned with defined objectives

Effective measurement combines multiple data sources — quantitative metrics, qualitative assessments, and stakeholder feedback — all aligned with clearly defined objectives for a comprehensive evaluation.

Question 80: A patient in Phase I PACU develops sudden onset atrial fibrillation with a ventricular rate of 140 bpm and a blood pressure of 88/54 mmHg. The priority intervention is:

Administer adenosine 6 mg rapid IV push
Apply carotid massage and reassess in 5 minutes
Synchronized cardioversion after notifying the anesthesiologist/cardiologist (Correct answer)
Administer amiodarone 150 mg IV over 10 minutes

Correct answer: Synchronized cardioversion after notifying the anesthesiologist/cardiologist

Hemodynamically unstable atrial fibrillation with hypotension requires immediate synchronized cardioversion per ACLS guidelines.

Question 81: The nurse is preparing to suction a patient via nasotracheal route in the PACU. Which action is essential BEFORE suctioning?

Pre-oxygenate the patient with 100% oxygen for at least 30 seconds (Correct answer)
Administer 5mL normal saline into the airway to loosen secretions
Set suction pressure to the highest available setting for efficiency
Have the patient perform a Valsalva maneuver to close the glottis

Correct answer: Pre-oxygenate the patient with 100% oxygen for at least 30 seconds

Pre-oxygenation with 100% oxygen for at least 30 seconds before suctioning reduces the risk of hypoxemia caused by oxygen removal during the suctioning procedure.

Question 82: A Phase II patient who is ready for discharge asks the nurse if they can drive themselves home since they feel completely normal. The appropriate response is:

Discharge the patient if their Aldrete score is 10/10
Explain that driving is prohibited for 24 hours after general or regional anesthesia regardless of how they feel (Correct answer)
Allow discharge if the patient demonstrates coordination by walking steadily down the hall
Allow driving if the patient received only local anesthesia with minimal sedation

Correct answer: Explain that driving is prohibited for 24 hours after general or regional anesthesia regardless of how they feel

Residual anesthetic and sedative effects impair judgment and reaction time even when patients feel subjectively normal, making driving unsafe for at least 24 hours.

Question 83: Which of the following best describes a key competency required for pediatric perianesthesia nursing in CAPA practice?

Reliance on a single methodology for all situations
Memorization of all relevant regulations without understanding context
Strong analytical skills combined with effective communication and ethical judgment (Correct answer)
The ability to work independently without any oversight

Correct answer: Strong analytical skills combined with effective communication and ethical judgment

CAPA professionals working in pediatric perianesthesia nursing need analytical skills to assess situations, communication skills to convey findings, and ethical judgment to make sound decisions.

Question 84: A patient in Phase II recovery reports dizziness when standing. SpO2 is 98%, BP is 95/60 mmHg supine and 75/50 mmHg standing. What is the most appropriate action?

Discharge with a responsible adult driver
Administer ephedrine 5 mg IV
Apply compression stockings and ambulate slowly
Return the patient to supine, give IV fluid bolus, and reassess (Correct answer)

Correct answer: Return the patient to supine, give IV fluid bolus, and reassess

Orthostatic hypotension requires the patient to return to supine position and receive volume resuscitation before reattempting ambulation.

Question 85: What is the MOST common cause of delayed emergence (failure to awaken) in the PACU?

Hyponatremia from IV fluid administration
Malignant hyperthermia complication
Residual effects of anesthetic agents and opioids (Correct answer)
Perioperative cerebrovascular accident

Correct answer: Residual effects of anesthetic agents and opioids

Residual anesthetic and opioid effects are by far the most common cause of delayed emergence, as pharmacokinetic variability can prolong their CNS depressant effects.

Question 86: What is the recommended initial IV dose of dantrolene when treating a confirmed malignant hyperthermia crisis?

0.5 mg/kg IV
5 mg/kg IV
2.5 mg/kg IV (Correct answer)
1 mg/kg IV

Correct answer: 2.5 mg/kg IV

The initial dose is 2.5 mg/kg IV, repeated every 5 minutes as needed to a maximum of 10 mg/kg until symptoms resolve.

Question 87: Liposomal bupivacaine (Exparel) is used for postoperative analgesia. What distinguishes it from standard bupivacaine regarding its pharmacokinetics?

Faster onset due to lipid encapsulation
Lower maximum concentration reducing efficacy
Greater CNS penetration causing more sedation
Extended release providing analgesia up to 72 hours (Correct answer)

Correct answer: Extended release providing analgesia up to 72 hours

Liposomal bupivacaine uses DepoFoam technology for sustained release, extending analgesia to 72 hours compared to standard bupivacaine's 8-12 hours.

Question 88: A patient recovering from a TAP (transversus abdominis plane) block reports sudden onset of nausea and lightheadedness. The nurse notes the patient is pale and diaphoretic. What should the nurse suspect FIRST?

Local anesthetic systemic toxicity from the TAP block (Correct answer)
Postoperative nausea and vomiting related to general anesthesia
Vasovagal syncope from postoperative anxiety
Opioid-related side effects from pre-operative medication

Correct answer: Local anesthetic systemic toxicity from the TAP block

Sudden onset of systemic symptoms following a TAP block—a high-volume technique—should prompt suspicion of LAST, especially with CNS and cardiovascular signs.

Question 89: A patient with a popliteal sciatic nerve block is being prepared for discharge. Which instruction is MOST important regarding foot safety?

Begin full weight-bearing immediately to restore function
Inspect the foot for injury frequently since sensation is impaired (Correct answer)
Elevate the foot above heart level for 24 hours
Apply heat to the foot to promote circulation

Correct answer: Inspect the foot for injury frequently since sensation is impaired

With impaired sensation from a sciatic block, patients cannot feel injury, so frequent inspection is essential to prevent unrecognized trauma.

Question 90: A 4-year-old weighing 16 kg is to receive ketamine for procedural sedation. What is the appropriate IV sedation dose?

5 mg/kg (80 mg)
0.1–0.2 mg/kg (1.6–3.2 mg)
1–2 mg/kg (16–32 mg) (Correct answer)
0.5 mg/kg only for induction

Correct answer: 1–2 mg/kg (16–32 mg)

IV ketamine for procedural sedation in children is dosed at 1–2 mg/kg; the dissociative state provides analgesia and sedation while maintaining airway reflexes.

Question 91: During Phase I PACU recovery, a patient suddenly develops rigidity, hyperthermia (40.1°C), tachycardia, and hypercapnia. Which condition requires immediate action?

Serotonin syndrome
Thyroid storm
Neuroleptic malignant syndrome
Malignant hyperthermia (Correct answer)

Correct answer: Malignant hyperthermia

Malignant hyperthermia presents with hypercarbia, muscle rigidity, rapid temperature rise, and tachycardia after volatile anesthetic or succinylcholine exposure.

Question 92: A parent asks to stay with their child during IV placement before surgery. What is the recommended nursing response?

Decline due to infection control concerns
Allow parental presence as it reduces child anxiety (Correct answer)
Allow only if the child is under 2 years old
Decline as it increases procedure time

Correct answer: Allow parental presence as it reduces child anxiety

Evidence supports parental presence during preoperative procedures as it significantly reduces pediatric anxiety and improves cooperation.

Question 93: A PACU patient develops nausea and vomiting 30 minutes after receiving IV morphine. Which antiemetic mechanism is MOST directly targeting opioid-induced nausea?

D2 receptor antagonism at the chemoreceptor trigger zone (Correct answer)
Muscarinic receptor antagonism
5-HT3 receptor antagonism
Histamine H1 receptor antagonism

Correct answer: D2 receptor antagonism at the chemoreceptor trigger zone

Opioids stimulate dopamine D2 receptors in the chemoreceptor trigger zone; dopamine antagonists like prochlorperazine or droperidol most directly counter this mechanism.

Question 94: A post-surgical patient in the PACU is exhibiting signs of malignant hyperthermia (MH). Which laboratory result would be MOST consistent with an MH crisis?

Respiratory alkalosis with hypokalemia
Metabolic alkalosis with hypocalcemia
Respiratory acidosis with elevated sodium
Metabolic acidosis with elevated creatine kinase (Correct answer)

Correct answer: Metabolic acidosis with elevated creatine kinase

MH produces intense hypermetabolism causing metabolic (and respiratory) acidosis, and massive muscle destruction elevates creatine kinase (CK) markedly.

Question 95: In the context of CAPA certification, what is the most important consideration when implementing thermoregulation & fluid management?

Completing implementation as quickly as possible regardless of quality
Ensuring alignment with established standards, stakeholder needs, and best practices (Correct answer)
Delegating all responsibilities to junior staff
Minimizing documentation to save time

Correct answer: Ensuring alignment with established standards, stakeholder needs, and best practices

When implementing thermoregulation & fluid management, CAPA professionals must ensure alignment with industry standards and stakeholder needs. Hasty implementation without proper planning often leads to compliance issues and suboptimal outcomes.

Question 96: Which assessment finding is the EARLIEST indicator of hypovolemia in a PACU patient?

Decreased blood pressure
Tachycardia (Correct answer)
Altered mental status
Oliguria

Correct answer: Tachycardia

Tachycardia is typically the earliest compensatory response to hypovolemia, occurring before hypotension as the body attempts to maintain cardiac output.

Question 97: Which temperature monitoring site provides the MOST accurate core temperature reading in an ambulatory surgery patient?

Rectal
Axillary
Oral
Tympanic membrane (Correct answer)

Correct answer: Tympanic membrane

Tympanic membrane temperature reflects hypothalamic temperature via the carotid artery supply, providing accurate core temperature measurement.

Question 98: Which patient populations are at HIGHEST risk for emergence delirium in the PACU?

ASA III patients undergoing cardiac surgery
Middle-aged women undergoing laparoscopic procedures
Patients who received neuraxial anesthesia
Elderly patients and young children (Correct answer)

Correct answer: Elderly patients and young children

Elderly patients and young children are at highest risk for emergence delirium due to age-related CNS vulnerability and reduced ability to process and recover from anesthetic effects.

Question 99: A patient who received spinal anesthesia is ready for discharge when which of the following criteria is met?

Motor block resolved but sensory block may persist
Patient able to bear weight for 30 seconds
Return of perianal sensation, plantar flexion, and proprioception (Correct answer)
Absence of any sensory block in the lower extremities

Correct answer: Return of perianal sensation, plantar flexion, and proprioception

Return of perianal (S4-S5) sensation, plantar flexion, and proprioception confirms adequate regression of spinal block for safe discharge.

Question 100: A patient receives ondansetron 4 mg IV at the end of surgery. Two hours later in the PACU they are vomiting. What is the most appropriate rescue antiemetic?

Dexamethasone 8 mg IV
Repeat ondansetron 4 mg IV
Promethazine 12.5 mg IV
Metoclopramide 10 mg IV (Correct answer)

Correct answer: Metoclopramide 10 mg IV

When a 5-HT3 antagonist fails or its duration has elapsed, a drug from a different class such as metoclopramide (dopamine antagonist) should be used for rescue.

Question 101: A patient recovering from a femoral nerve block reports inability to flex the knee 4 hours post-procedure. What is the PRIORITY nursing action?

Apply a compression bandage to reduce edema
Assess for signs of compartment syndrome and notify the anesthesia provider (Correct answer)
Encourage the patient to ambulate to restore motor function
Reassure the patient this is expected and document the finding

Correct answer: Assess for signs of compartment syndrome and notify the anesthesia provider

Prolonged motor block with inability to flex the knee may indicate complications such as compartment syndrome, requiring immediate assessment and provider notification.

Question 102: Which developmental stage consideration is most important when preparing a 7-year-old for ambulatory surgery?

Providing honest, simple explanations of what they will see and feel (Correct answer)
Delegating all education to parents only

It focuses exclusively on cost reduction
It is optional and only necessary during certification renewal
It drives ongoing enhancement of practices, processes, and outcomes through systematic evaluation (Correct answer)

Correct answer: It drives ongoing enhancement of practices, processes, and outcomes through systematic evaluation

Continuous improvement is fundamental to professional practice in regional anesthesia recovery care, involving regular evaluation, feedback integration, and process enhancement to maintain high standards.

Question 105: A PACU team wants to evaluate whether their new EBP-based PONV protocol improved patient outcomes. Which method best measures program effectiveness?

Reviewing only the protocol documentation for completeness
Comparing pre- and post-implementation PONV incidence rates (Correct answer)
Counting the number of antiemetic agents ordered
Staff satisfaction surveys about the new protocol

Correct answer: Comparing pre- and post-implementation PONV incidence rates

Comparing pre- and post-implementation outcome data (PONV incidence) directly measures clinical effectiveness of the EBP change.

Question 106: Which finding in the PACU would indicate the need to defer ambulatory discharge and arrange inpatient admission?

Mild dizziness resolving with IV fluid bolus
PONV requiring one additional dose of ondansetron
Persistent SpO2 88% on 4L nasal cannula after 90 minutes (Correct answer)
Pain score of 5/10 controlled with oral analgesics

Correct answer: Persistent SpO2 88% on 4L nasal cannula after 90 minutes

Persistent hypoxemia requiring supplemental oxygen beyond 90 minutes indicates the patient cannot safely be discharged to an unmonitored home environment.

Question 107: A patient in the PACU develops sudden onset stridor after extubation. Which intervention should the nurse perform FIRST?

Reintubate immediately
Administer IV succinylcholine
Apply jaw thrust and supplemental oxygen (Correct answer)
Administer IV neostigmine

Correct answer: Apply jaw thrust and supplemental oxygen

Initial management of post-extubation stridor includes positioning, jaw thrust, and supplemental oxygen before escalating to pharmacologic or airway interventions.

Question 108: During a preoperative phone screening, a patient states she was told she has 'a heart murmur' but has never had a cardiac workup. She is now scheduled for a colonoscopy under MAC. What is the BEST next step?

Proceed; colonoscopy is low-risk and doesn't require cardiac evaluation
Obtain a cardiology clearance before scheduling (Correct answer)
Ask the patient to bring her medical records on the day of surgery
Perform an ECG on the day of the procedure

Correct answer: Obtain a cardiology clearance before scheduling

An uncharacterized heart murmur warrants cardiology evaluation to rule out hemodynamically significant valvular disease before elective sedation.

Question 109: In the context of CAPA certification, what is the most important consideration when implementing discharge criteria & planning?

Ensuring alignment with established standards, stakeholder needs, and best practices (Correct answer)
Completing implementation as quickly as possible regardless of quality
Delegating all responsibilities to junior staff

Correct answer: Ensuring alignment with established standards, stakeholder needs, and best practices

When implementing discharge criteria & planning, CAPA professionals must ensure alignment with industry standards and stakeholder needs. Hasty implementation without proper planning often leads to compliance issues and suboptimal outcomes.

Question 110: A patient returns from a 2-hour hysteroscopy with documented fluid deficit of 1,500 mL absorbed irrigation fluid. The nurse should MOST closely monitor for:

Hypovolemic shock
Hyperkalemia from cellular breakdown
Metabolic alkalosis
TURP syndrome with hyponatremia and cerebral edema (Correct answer)

Correct answer: TURP syndrome with hyponatremia and cerebral edema

Absorption of hypotonic irrigation fluid during hysteroscopy causes TURP-like syndrome with dilutional hyponatremia and risk of cerebral edema.

Question 111: When a CAPA professional encounters an unfamiliar challenge in nausea & vomiting prevention, what is the recommended first course of action?

Apply the solution used for the most recent similar problem without adaptation
Postpone addressing the issue indefinitely
Research applicable standards, consult with subject matter experts, and document the approach (Correct answer)
Proceed based on personal intuition alone

Correct answer: Research applicable standards, consult with subject matter experts, and document the approach

Professional practice requires a methodical approach to unfamiliar challenges: research the applicable standards, consult experts when needed, and document the reasoning for the chosen approach.

Question 112: A 10-year-old with a known history of malignant hyperthermia (MH) susceptibility undergoes ambulatory surgery. Which anesthetic approach is required?

Succinylcholine for rapid sequence intubation
Sevoflurane inhalation induction for smoother emergence
Desflurane maintenance as it is newer and safer
Total IV anesthesia (TIVA) with non-triggering agents only (Correct answer)

Correct answer: Total IV anesthesia (TIVA) with non-triggering agents only

MH-susceptible patients must receive only non-triggering agents (TIVA with propofol/opioids/non-depolarizing NMBAs); all volatile agents and succinylcholine are contraindicated.

Question 113: Which pediatric pain/anxiety assessment tool is appropriate for a school-age child in the PACU?

FLACC scale
FACES Pain Scale-Revised (Correct answer)
CRIES scale
Visual Analog Scale

Correct answer: FACES Pain Scale-Revised

The FACES Pain Scale-Revised is validated for children ages 4-12 and allows self-report of pain and distress levels.

Question 114: Which warming method is CONTRAINDICATED in a patient with peripheral vascular disease undergoing ambulatory foot surgery?

Increasing OR room temperature
Forced-air warming blanket over upper body
Direct heating pad applied to the surgical extremity (Correct answer)
Warm IV fluids

Correct answer: Direct heating pad applied to the surgical extremity

Direct heat application to ischemic extremities in peripheral vascular disease can cause thermal injury due to impaired sensation and circulation.

Question 115: Which of the following represents an appropriate MINIMUM criterion for oral fluid tolerance before ambulatory discharge?

Patient has eaten a full light meal without symptoms
Patient consumed at least 500 mL of clear liquids
Patient tolerates a small amount of fluid or crackers without nausea or vomiting (Correct answer)
Patient requests food and is hungry

Correct answer: Patient tolerates a small amount of fluid or crackers without nausea or vomiting

Routine mandatory oral fluid intake before discharge is no longer required; tolerance of small amounts without vomiting is sufficient for most procedures.

Question 116: Which assessment helps reduce aspiration risk during anesthesia?

Checking pupil response
Confirming NPO status (Correct answer)
Assessing bowel sounds
Inspecting IV site

Correct answer: Confirming NPO status

Confirming NPO (nil per os, or nothing by mouth) status is a critical assessment to reduce the risk of aspiration during anesthesia. When a patient has food or liquids in their stomach, there is a risk of regurgitation and aspiration into the lungs during induction of anesthesia, which can lead to severe pneumonia or acute respiratory distress syndrome. Adhering to NPO guidelines ensures the stomach is empty, minimizing this dangerous complication.

Question 117: A patient is being evaluated before discharge after a femoral nerve block for knee surgery. Which finding indicates SAFE discharge readiness?

Knee flexion strength is 4/5 compared to 5/5 preoperatively
Patient reports mild paresthesia along the medial thigh
Patient is pain-free and states they do not need discharge instructions
Patient ambulates safely with crutches and verbalized limb protection precautions (Correct answer)

Correct answer: Patient ambulates safely with crutches and verbalized limb protection precautions

Safe ambulation with crutches and demonstrated understanding of limb protection indicates the patient has the necessary function and knowledge for safe discharge with a residual femoral block.

Question 118: A PACU nurse administers promethazine 25 mg IV push to a patient with PONV. What serious complication is associated with this route of administration?

Severe tissue necrosis if inadvertent intra-arterial or perivascular injection occurs (Correct answer)
Acute hepatic failure with standard doses
Prolonged QTc and cardiac dysrhythmia
Anaphylaxis due to preservative sensitivity

Correct answer: Severe tissue necrosis if inadvertent intra-arterial or perivascular injection occurs

IV promethazine carries a black box warning for severe tissue necrosis, gangrene, and amputation risk if administered intra-arterially or if extravasation occurs.

Question 119: What role does continuous improvement play in thermoregulation & fluid management for CAPA certified professionals?

It focuses exclusively on cost reduction
It drives ongoing enhancement of practices, processes, and outcomes through systematic evaluation (Correct answer)
It is optional and only necessary during certification renewal
It applies only to new professionals in their first year

Correct answer: It drives ongoing enhancement of practices, processes, and outcomes through systematic evaluation

Continuous improvement is fundamental to professional practice in thermoregulation & fluid management, involving regular evaluation, feedback integration, and process enhancement to maintain high standards.

Question 120: What is the primary focus in the immediate postanesthesia period?

Changing surgical dressings
Reviewing dietary needs
Monitoring airway and vital signs (Correct answer)
Initiating discharge paperwork

Correct answer: Monitoring airway and vital signs

Airway, breathing, and circulation (ABCs) are top priorities to ensure patient stability after anesthesia.

Question 121: In the ambulatory setting, which factor MOST strongly predicts the need for IV fluid resuscitation in PACU rather than oral hydration?

BMI greater than 30
Preoperative NPO status longer than 8 hours
Patient age over 65
Procedure duration greater than 60 minutes with significant blood loss (Correct answer)

Correct answer: Procedure duration greater than 60 minutes with significant blood loss

Significant intraoperative blood loss during longer procedures creates volume deficits that require IV replacement rather than oral hydration.

Question 122: Post-extubation stridor heard in the PACU most commonly indicates which underlying problem?

Lower airway bronchospasm
Pneumothorax
Pulmonary embolism
Subglottic edema or partial laryngospasm (Correct answer)

Correct answer: Subglottic edema or partial laryngospasm

Stridor is a high-pitched inspiratory sound indicating upper airway obstruction, most commonly from subglottic edema or incomplete laryngospasm after extubation.

Question 123: A patient with a documented history of motion sickness is scheduled for laparoscopic cholecystectomy. Which combination prophylaxis is most appropriate?

Dexamethasone at induction plus ondansetron near end of surgery (Correct answer)
Droperidol alone at induction
Scopolamine patch applied the night before plus metoclopramide at induction
Ondansetron alone 30 min before emergence

Correct answer: Dexamethasone at induction plus ondansetron near end of surgery

Multimodal prophylaxis using dexamethasone at induction and a 5-HT3 antagonist near emergence is the evidence-based standard for high-risk patients.

Question 124: An ambulatory surgery patient is being monitored for PONV. Which Apfel score component is MOST strongly modifiable by nursing intervention?

Non-smoking status
Postoperative opioid use (Correct answer)
Female sex
History of PONV or motion sickness

Correct answer: Postoperative opioid use

Postoperative opioid use is the one Apfel risk factor most amenable to nursing intervention through multimodal analgesia and opioid-sparing techniques.

Question 125: A 45-year-old female patient reports menstrual irregularity and hot flashes. The surgeon orders a pregnancy test. She refuses, stating she cannot be pregnant. What is the nurse's BEST response?

Notify security
Cancel the surgery immediately
Explain that facility policy requires the test for patient safety (Correct answer)
Document the refusal and proceed without the test

Correct answer: Explain that facility policy requires the test for patient safety

The nurse should explain institutional policy and the safety rationale because pregnancy significantly alters anesthetic risk and medication safety.

Question 126: Which of the following best describes a key competency required for nausea & vomiting prevention in CAPA practice?

Memorization of all relevant regulations without understanding context
Strong analytical skills combined with effective communication and ethical judgment (Correct answer)
Reliance on a single methodology for all situations

Question 127: When a CAPA professional encounters an unfamiliar challenge in evidence-based practice in pacu, what is the recommended first course of action?

Apply the solution used for the most recent similar problem without adaptation
Research applicable standards, consult with subject matter experts, and document the approach (Correct answer)
Postpone addressing the issue indefinitely
Proceed based on personal intuition alone

Correct answer: Research applicable standards, consult with subject matter experts, and document the approach

Professional practice requires a methodical approach to unfamiliar challenges: research the applicable standards, consult experts when needed, and document the reasoning for the chosen approach.

Question 128: In the ambulatory PACU, which patient is LEAST appropriate for fast-tracking directly to Phase II recovery?

Patient with BMI 42 and OSA after monitored anesthesia care (Correct answer)
Patient after spinal anesthesia for knee arthroscopy with motor function returning
Healthy adult after brief general anesthesia, fully awake and oriented
ASA I patient after local anesthesia with sedation, Aldrete score 9

Correct answer: Patient with BMI 42 and OSA after monitored anesthesia care

Patients with OSA and high BMI require closer Phase I monitoring due to elevated risk of airway obstruction and hypoxia during recovery.

Question 129: A patient expresses that they do not understand the discharge instructions due to a language barrier. What is the MOST appropriate action?

Use a qualified medical interpreter to review all discharge instructions before the patient leaves (Correct answer)
Simplify the instructions and use gestures to communicate
Ask the patient's family member to translate the written instructions
Document that instructions were provided and discharge the patient

Correct answer: Use a qualified medical interpreter to review all discharge instructions before the patient leaves

A qualified medical interpreter ensures accurate communication of discharge instructions, preventing patient safety errors caused by language barriers.

Question 130: Which assessment tool is MOST appropriate for screening for postoperative delirium in elderly patients?

Visual Analog Scale
Confusion Assessment Method (CAM) (Correct answer)
FLACC scale
Richmond Agitation-Sedation Scale (RASS)

Correct answer: Confusion Assessment Method (CAM)

The Confusion Assessment Method (CAM) is the gold standard tool for identifying delirium in non-ICU patients, including postoperative elderly adults.

Question 131: Which clinical indicator is most reliable for assessing adequate reversal of neuromuscular blockade before PACU discharge?

Respiratory rate > 12 breaths/min
SpO2 > 95% on room air
Train-of-four ratio ≥ 0.9 (Correct answer)
Patient can open eyes on command

Correct answer: Train-of-four ratio ≥ 0.9

A train-of-four (TOF) ratio of ≥0.9 indicates adequate neuromuscular recovery and significantly reduces the risk of residual paralysis.

Question 132: A patient receiving transfusion of 2 units packed red blood cells in PACU develops fever, chills, and flank pain 30 minutes into the transfusion. The FIRST nursing action is:

Slow the transfusion rate and administer diphenhydramine
Obtain blood cultures and continue transfusion
Administer acetaminophen and continue transfusion at slower rate
Stop the transfusion immediately, keep IV open with NS, and notify provider (Correct answer)

Correct answer: Stop the transfusion immediately, keep IV open with NS, and notify provider

Symptoms of acute hemolytic transfusion reaction require immediate transfusion cessation, IV access maintenance with NS, and immediate provider notification.

Question 133: A preoperative nurse reviews that a patient takes varenicline (Chantix) for smoking cessation. Which behavioral consideration should be documented related to this medication?

Increased anesthetic requirements
Neuropsychiatric symptoms including mood changes and suicidal ideation (Correct answer)
Risk of bronchospasm intraoperatively
Prolonged sedation postoperatively

Correct answer: Neuropsychiatric symptoms including mood changes and suicidal ideation

Varenicline carries an FDA warning for neuropsychiatric adverse effects including depression, agitation, and suicidal ideation that must be documented preoperatively.

Question 134: Which non-pharmacologic method can aid in pain control postoperatively?

Excessive talking
Frequent repositioning only
Deep breathing exercises (Correct answer)
Fasting

Correct answer: Deep breathing exercises

Deep breathing and relaxation techniques support comfort and reduce stress-related pain.

Question 135: A patient in the PACU develops acute pulmonary edema with pink frothy secretions and SpO2 of 78%. What is the IMMEDIATE nursing action?

Insert a Foley catheter to monitor urine output and fluid balance
Administer furosemide 40 mg IV to reduce preload
Obtain a stat portable chest X-ray to confirm diagnosis
Sit the patient upright, apply high-flow oxygen, and call the anesthesia provider (Correct answer)

Correct answer: Sit the patient upright, apply high-flow oxygen, and call the anesthesia provider

Upright positioning reduces preload and improves diaphragm excursion; high-flow oxygen corrects hypoxia — both are immediate nursing actions while the provider is notified.

Question 136: A patient's discharge is delayed due to uncontrolled pain rating 8/10. She received her maximum IV opioid dose. Which non-opioid intervention should the nurse prioritize NEXT?

Administer oral oxycodone/acetaminophen per discharge orders (Correct answer)
Position the patient supine and dim the lights
Apply a cold pack to the surgical site
Administer an additional half-dose of IV morphine

Correct answer: Administer oral oxycodone/acetaminophen per discharge orders

Transitioning to oral analgesics per discharge orders is the appropriate next step once IV opioid limits are reached, facilitating the transition for home pain management.

Question 137: Which of the following best describes a key competency required for phase i & phase ii recovery care in CAPA practice?

Strong analytical skills combined with effective communication and ethical judgment (Correct answer)
Reliance on a single methodology for all situations
Memorization of all relevant regulations without understanding context
The ability to work independently without any oversight

Correct answer: Strong analytical skills combined with effective communication and ethical judgment

CAPA professionals working in phase i & phase ii recovery care need analytical skills to assess situations, communication skills to convey findings, and ethical judgment to make sound decisions.

Question 138: A patient who received a cervical nerve block for shoulder surgery develops dyspnea 30 minutes postoperatively. The MOST likely complication is:

Pulmonary embolism
Bilateral vocal cord paralysis
Ipsilateral phrenic nerve palsy causing hemidiaphragm paresis (Correct answer)
Opioid-induced respiratory depression

Correct answer: Ipsilateral phrenic nerve palsy causing hemidiaphragm paresis

Interscalene brachial plexus blocks reliably cause ipsilateral phrenic nerve palsy, resulting in hemidiaphragm paresis and reduced respiratory capacity.

Question 139: A patient arrives in Phase I PACU with pinpoint pupils, a respiratory rate of 6 breaths/min, and SpO2 of 82%. The most likely etiology and initial intervention are:

Opioid-induced respiratory depression; administer naloxone titrated in small doses with airway support (Correct answer)
Hypoglycemia; administer 50% dextrose 25g IV
Residual neuromuscular blockade; administer neostigmine 5mg with glycopyrrolate
Pulmonary embolism; administer anticoagulation and call a code

Correct answer: Opioid-induced respiratory depression; administer naloxone titrated in small doses with airway support

The classic triad of pinpoint pupils, bradypnea, and hypoxia indicates opioid overdose; titrated naloxone with airway support is the appropriate reversal strategy.

Question 140: A Phase II recovery nurse is reviewing a patient's discharge prescriptions. The patient is going home with oxycodone 5 mg PRN and ibuprofen 600 mg q6h. Which additional analgesic recommendation would BEST complete the multimodal regimen?

Add hydromorphone 2 mg PRN as needed
Add a fentanyl patch 12 mcg/hr
Add tramadol 50 mg PRN for breakthrough pain
Add scheduled acetaminophen 500 mg q6h alternating with ibuprofen (Correct answer)

Correct answer: Add scheduled acetaminophen 500 mg q6h alternating with ibuprofen

Scheduled acetaminophen alternating with ibuprofen maximizes non-opioid coverage through different mechanisms, reducing opioid consumption and improving pain control.

Question 141: What is the minimum urine output considered acceptable before discharging a patient home from Phase II PACU?

At least 100 mL total output
Voiding is not a universal discharge requirement for all patients (Correct answer)
At least 30 mL since arrival
At least 0.5 mL/kg/hr for two consecutive hours

Correct answer: Voiding is not a universal discharge requirement for all patients

Current evidence-based guidelines do not mandate voiding as a universal discharge criterion unless the patient had spinal anesthesia or a procedure with high urinary retention risk.

Question 142: What role does continuous improvement play in pediatric perianesthesia nursing for CAPA certified professionals?

It applies only to new professionals in their first year
It is optional and only necessary during certification renewal
It drives ongoing enhancement of practices, processes, and outcomes through systematic evaluation (Correct answer)
It focuses exclusively on cost reduction

Correct answer: It drives ongoing enhancement of practices, processes, and outcomes through systematic evaluation

Continuous improvement is fundamental to professional practice in pediatric perianesthesia nursing, involving regular evaluation, feedback integration, and process enhancement to maintain high standards.

Question 143: What is the definitive treatment for refractory cardiac arrest caused by local anesthetic systemic toxicity (LAST)?

High-dose epinephrine bolus (>1 mg IV)
Calcium chloride 1 g IV
Sodium bicarbonate 1 mEq/kg IV
20% lipid emulsion (intralipid) IV bolus (Correct answer)

Correct answer: 20% lipid emulsion (intralipid) IV bolus

20% lipid emulsion acts as a 'lipid sink,' sequestering lipophilic local anesthetic from cardiac tissue, and is the definitive ASRA-recommended treatment for LAST cardiac arrest.

Question 144: Which drug is the reversal agent for neuromuscular blockade caused by rocuronium when using sugammadex?

Sugammadex encapsulates rocuronium directly (Correct answer)
Neostigmine
Physostigmine
Flumazenil

Correct answer: Sugammadex encapsulates rocuronium directly

Sugammadex works by encapsulating and inactivating steroidal neuromuscular blocking agents like rocuronium and vecuronium.

Question 145: A patient in the PACU is receiving a diltiazem infusion for atrial fibrillation with rapid ventricular response. Which vital sign requires the most vigilance?

Blood pressure (Correct answer)
Oxygen saturation
Respiratory rate
Temperature

Correct answer: Blood pressure

Diltiazem is a calcium channel blocker that can cause significant hypotension; blood pressure must be monitored closely during infusion.

Question 146: A 2-year-old child in the PACU develops stridor and a barking cough 30 minutes after extubation. What is the most likely diagnosis?

Aspiration pneumonitis
Bronchospasm
Post-extubation croup (subglottic edema) (Correct answer)
Laryngospasm

Correct answer: Post-extubation croup (subglottic edema)

Barking cough with inspiratory stridor developing 30–60 minutes post-extubation in a toddler is classic post-extubation croup due to subglottic mucosal edema.

Question 147: A post-anesthesia patient has a PaO2 of 70 mmHg on 4L nasal cannula (estimated FiO2 ~0.36). What is the approximate P/F ratio, and what does it indicate?

P/F = 194, indicating mild ARDS (Correct answer)
P/F = 175, indicating moderate respiratory failure
P/F = 350, indicating adequate gas exchange
P/F = 280, indicating normal oxygenation efficiency

Correct answer: P/F = 194, indicating mild ARDS

P/F ratio = PaO2 ÷ FiO2 = 70 ÷ 0.36 ≈ 194, which falls in the mild ARDS range (200-300) and indicates impaired oxygenation requiring close monitoring.

Question 148: Which of the following is a Phase II PACU discharge criterion using the Post-Anesthetic Discharge Scoring System (PADSS)?

Pain controlled with oral analgesics and rated ≤ 4/10 (Correct answer)
SpO2 > 98% on room air for 30 minutes
Ability to perform a straight leg raise
Aldrete score ≥ 9

Correct answer: Pain controlled with oral analgesics and rated ≤ 4/10

PADSS evaluates vital signs, ambulation, nausea/vomiting, pain, and surgical bleeding; pain controlled with oral analgesics rated acceptable by the patient is a scored criterion.

Question 149: A perianesthesia nurse notes that a patient's train-of-four (TOF) ratio is 0.7 after reversal with neostigmine. What does this indicate?

The TOF ratio is invalid without a baseline measurement
The patient is over-reversed and at risk for cholinergic crisis
Full neuromuscular recovery; the patient can be safely discharged from Phase I
Residual neuromuscular blockade; the patient may have impaired airway protection (Correct answer)

Correct answer: Residual neuromuscular blockade; the patient may have impaired airway protection

A TOF ratio below 0.9 indicates residual neuromuscular blockade, which can impair airway reflexes and increase aspiration risk.

Question 150: According to evidence-based practice, how should a PACU nurse respond when a patient's pain score does not improve after a second opioid dose?

Apply ice to the surgical site only
Document and wait for the surgeon to re-evaluate
Administer a third opioid dose at double the original amount
Reassess for alternative pain sources and consider non-opioid adjuncts (Correct answer)

Correct answer: Reassess for alternative pain sources and consider non-opioid adjuncts

Evidence-based pain management requires reassessment and multimodal approaches when opioids alone are ineffective.

Question 151: A post-thyroidectomy patient develops inspiratory stridor, neck swelling, and dysphagia 2 hours post-op. What is the priority action?

Prepare for immediate reintubation
Place patient in high Fowler's position and call surgeon stat
Open the neck wound at bedside to relieve hematoma pressure (Correct answer)
Administer dexamethasone 10 mg IV

Correct answer: Open the neck wound at bedside to relieve hematoma pressure

Neck hematoma post-thyroidectomy causing airway compromise requires immediate wound opening to decompress before complete airway obstruction occurs.

Question 152: Which Aldrete score component specifically addresses the patient's ability to maintain their own airway in the PACU?

Circulation
Consciousness
Activity
Respiration (Correct answer)

Correct answer: Respiration

The Respiration component of the Aldrete score evaluates ability to breathe deeply and cough effectively, which reflects maintenance of airway patency.

Question 153: The ASPAN evidence-based practice model recommends that nurses grade evidence before implementing a practice change. What does a Grade A recommendation signify?

Animal study data extrapolated to humans
Expert opinion with limited clinical data
Evidence from at least one well-designed RCT or systematic review (Correct answer)
Observational data from a single institution

Correct answer: Evidence from at least one well-designed RCT or systematic review

Grade A recommendations are supported by strong evidence from randomized controlled trials or systematic reviews.

Question 154: A patient who underwent 4-hour abdominal surgery under general anesthesia is being assessed using the Aldrete scoring system. A respiratory score of '1' is assigned when:

SpO2 is greater than 92% on room air
The patient breathes deeply and coughs freely
Dyspnea or limited breathing is present (Correct answer)
The patient is apneic

Correct answer: Dyspnea or limited breathing is present

An Aldrete respiratory score of 1 indicates dyspnea, shallow breathing, or limited respiratory effort; a score of 2 indicates normal breathing, and 0 indicates apnea.

Question 155: Which nursing assessment finding would most support delaying discharge of an ambulatory patient due to PONV?

Patient requests an antiemetic before eating the discharge snack
Patient reports mild queasiness but denies vomiting and has tolerated sips of water
Patient's Apfel score was 3 and she received three prophylactic antiemetics preoperatively
Patient has vomited twice in the last 30 minutes and cannot retain oral fluids or medications (Correct answer)

Correct answer: Patient has vomited twice in the last 30 minutes and cannot retain oral fluids or medications

Repeated vomiting with inability to retain fluids or oral medications represents inadequate symptom control and a safety risk that prevents safe discharge.

Question 156: A patient in the PACU reports pain rated 7/10 after ambulatory knee arthroscopy. They received fentanyl intraoperatively. Which multimodal analgesic agent is MOST appropriate to add first?

Meperidine 25 mg IV
IV hydromorphone 1 mg
Ketorolac 15-30 mg IV (Correct answer)
Morphine 4 mg IV

Correct answer: Ketorolac 15-30 mg IV

Ketorolac is a first-line NSAID adjunct in multimodal analgesia that reduces opioid requirements without causing respiratory depression.

Question 157: When a CAPA professional encounters an unfamiliar challenge in pediatric perianesthesia nursing, what is the recommended first course of action?

Research applicable standards, consult with subject matter experts, and document the approach (Correct answer)
Postpone addressing the issue indefinitely
Apply the solution used for the most recent similar problem without adaptation
Proceed based on personal intuition alone

Correct answer: Research applicable standards, consult with subject matter experts, and document the approach

Professional practice requires a methodical approach to unfamiliar challenges: research the applicable standards, consult experts when needed, and document the reasoning for the chosen approach.

Question 158: A patient's PACU temperature is 35.2°C (95.4°F) after a 3-hour abdominal procedure under general anesthesia. Which complication is most directly associated with this finding?

Hypertensive crisis
Serotonin syndrome
Increased bleeding risk due to platelet dysfunction (Correct answer)
Malignant hyperthermia

Correct answer: Increased bleeding risk due to platelet dysfunction

Hypothermia impairs platelet aggregation and coagulation enzyme function, significantly increasing perioperative bleeding risk.

Question 159: Which electrolyte abnormality is most associated with prolonged QT interval and increased risk of Torsades de Pointes in the postanesthesia period?

Hyperphosphatemia
Hyperkalemia
Hypernatremia
Hypomagnesemia (Correct answer)

Correct answer: Hypomagnesemia

Hypomagnesemia prolongs the QT interval and is a common, correctable cause of Torsades de Pointes in postoperative patients.

Question 160: Which of the following interventions BEST reduces the risk of postoperative nausea and vomiting (PONV) in a high-risk ambulatory surgery patient?

Maintaining the patient in supine position throughout the recovery period
Multimodal prophylaxis combining a 5-HT3 antagonist with dexamethasone and TIVA technique (Correct answer)
Restricting all oral intake including water until 6 hours post-procedure
Administering morphine PCA for pain control to reduce overall opioid requirements

Correct answer: Multimodal prophylaxis combining a 5-HT3 antagonist with dexamethasone and TIVA technique

Multimodal PONV prophylaxis using agents from different classes combined with TIVA (avoiding volatile anesthetics) significantly reduces PONV incidence in high-risk patients.

Question 161: How should CAPA professionals handle confidential information related to regional anesthesia recovery care?

Share freely with all colleagues for transparency
Delete all records after project completion
Follow established protocols for data protection, access control, and disclosure in accordance with applicable regulations (Correct answer)
Store information without any security measures

Correct answer: Follow established protocols for data protection, access control, and disclosure in accordance with applicable regulations

Confidential information must be handled according to established protocols, regulatory requirements, and professional ethics standards, including proper access control and disclosure procedures.

Question 162: Which medication class is most commonly implicated in delayed awakening from general anesthesia in the elderly ambulatory patient?

Volatile anesthetics
Opioids
Neuromuscular blocking agents
Benzodiazepines (Correct answer)

Correct answer: Benzodiazepines

Benzodiazepines have prolonged half-lives in elderly patients due to reduced hepatic metabolism and increased volume of distribution, leading to delayed emergence.

Question 163: A patient in Phase II PACU reports dizziness and nausea after attempted ambulation. Orthostatic vital signs show BP drop of 25 mmHg systolic. The MOST appropriate intervention is:

Discharge the patient with instructions to rest at home
Administer ondansetron and attempt ambulation again in 10 minutes
Apply a compression device and call for wheelchair discharge
Return patient to supine, give a 250 mL IV fluid bolus, and reassess (Correct answer)

Correct answer: Return patient to supine, give a 250 mL IV fluid bolus, and reassess

Symptomatic orthostatic hypotension indicating volume depletion requires fluid bolus and reassessment before safe discharge can occur.

Question 164: Which strategy BEST promotes psychological safety for patients in the ambulatory PACU setting?

Routinely administering anxiolytics on arrival
Keeping the environment bright and busy to stimulate alertness
Minimizing all communication to reduce stimulation
Maintaining consistent, respectful communication and preserving patient dignity (Correct answer)

Correct answer: Maintaining consistent, respectful communication and preserving patient dignity

Consistent respectful communication and dignity-preserving care create a psychologically safe environment that reduces stress and builds patient trust.

Question 165: A 6-year-old with a history of severe needle phobia is scheduled for ambulatory surgery. Which premedication is most commonly used to reduce preoperative anxiety in pediatric patients?

Oral midazolam 0.5 mg/kg (max 15 mg) given 20–30 minutes before induction (Correct answer)
IM ketamine 4 mg/kg in the preoperative holding area
Oral diazepam the night before surgery
IV lorazepam given on arrival to pre-op

Correct answer: Oral midazolam 0.5 mg/kg (max 15 mg) given 20–30 minutes before induction

Oral midazolam 0.5 mg/kg (max 15 mg) given 20–30 minutes before induction is the most widely used and effective pediatric anxiolytic premedication.

Question 166: A patient is being discharged home after ambulatory surgery with a prescription for oxycodone. Which instruction is MOST important related to safe opioid use?

Take opioids around the clock to stay ahead of pain
Store opioids in a visible location for easy access
Do not drive, operate machinery, or consume alcohol while taking opioids (Correct answer)
Double the dose if pain is not controlled within 30 minutes

Correct answer: Do not drive, operate machinery, or consume alcohol while taking opioids

Opioids impair CNS function, making driving and alcohol consumption dangerous; patients must receive explicit counseling on these restrictions.

Question 167: An evidence-based postoperative nausea protocol includes risk stratification. Which tool is validated for predicting PONV risk in adults?

Ramsay Sedation Scale
Apfel Simplified Risk Score (Correct answer)
ASA Physical Status Classification
Mallampati Classification

Correct answer: Apfel Simplified Risk Score

The Apfel Simplified Risk Score uses four factors (female sex, non-smoking, PONV history, opioid use) to predict adult PONV risk.

Question 168: A PACU nurse notes a patient's end-tidal CO2 waveform has a 'shark fin' appearance with a prolonged expiratory phase. This pattern is MOST associated with:

Esophageal intubation
Hyperventilation from pain
Bronchospasm or obstructive airway disease (Correct answer)
Normal ventilation

Correct answer: Bronchospasm or obstructive airway disease

A 'shark fin' or slanted ETCO2 waveform with prolonged expiratory upslope indicates obstruction to expiratory airflow, characteristic of bronchospasm or COPD exacerbation.

Question 169: Which patient characteristic is NOT an independent risk factor in the Apfel simplified risk score for PONV?

History of motion sickness
Use of regional anesthesia (Correct answer)
Female sex
Non-smoker status

Correct answer: Use of regional anesthesia

The Apfel score uses female sex, non-smoking status, history of PONV/motion sickness, and postoperative opioid use — regional anesthesia is not one of its four factors.

Question 170: Which of the following best describes the Pediatric Anesthesia Emergence Delirium (PAED) scale?

A 5-item observational tool scored 0–20 assessing eye contact, purposefulness, and awareness of surroundings (Correct answer)
A behavioral checklist completed by parents post-discharge
A sedation scale based on response to verbal commands
A pain scale using facial expressions for children 3–7 years

Correct answer: A 5-item observational tool scored 0–20 assessing eye contact, purposefulness, and awareness of surroundings

The PAED scale scores five behaviors (eye contact, purposeful actions, awareness, restlessness, inconsolability) from 0–4 each, with scores ≥10 indicating delirium.

Question 171: In the context of CAPA certification, what is the most important consideration when implementing pediatric perianesthesia nursing?

Ensuring alignment with established standards, stakeholder needs, and best practices (Correct answer)
Minimizing documentation to save time
Completing implementation as quickly as possible regardless of quality
Delegating all responsibilities to junior staff

Correct answer: Ensuring alignment with established standards, stakeholder needs, and best practices

When implementing pediatric perianesthesia nursing, CAPA professionals must ensure alignment with industry standards and stakeholder needs. Hasty implementation without proper planning often leads to compliance issues and suboptimal outcomes.

Question 172: A patient emerges from general anesthesia biting the oropharyngeal airway and is extremely agitated. The nurse's PRIORITY action is:

Apply a jaw thrust and leave the airway in place
Administer IV midazolam immediately
Restrain the patient to prevent self-extubation
Remove the oral airway only after confirming adequate protective reflexes (Correct answer)

Correct answer: Remove the oral airway only after confirming adequate protective reflexes

An oral airway should be removed when the patient demonstrates adequate protective airway reflexes (e.g., purposeful attempts to remove it), because forceful biting indicates the patient is capable of maintaining their airway.

Question 173: Which Phase I PACU discharge criterion is specific to the ambulatory setting according to ASPAN standards?

Patient must tolerate oral fluids without nausea
Patient must ambulate 50 feet independently
Patient must be accompanied by a responsible adult escort (Correct answer)
Patient must have voided prior to discharge

Correct answer: Patient must be accompanied by a responsible adult escort

ASPAN standards require ambulatory surgery patients to be discharged in the care of a responsible, competent adult who can observe for complications at home.

Question 174: Emergence delirium is MOST commonly seen in which patient population in the PACU?

Elderly patients on beta-blockers
Young children and older adults (Correct answer)
Middle-aged adults with anxiety disorders
Patients who received spinal anesthesia

Correct answer: Young children and older adults

Young children (especially ages 2-6) and elderly adults are most susceptible to emergence delirium due to developmental and neurological factors.

Question 175: A patient in Phase I PACU after general anesthesia has a respiratory rate of 8 breaths/min and SpO2 of 90% on 4L nasal cannula. What is the priority intervention?

Administer naloxone 0.4 mg IV
Apply jaw thrust and stimulate the patient (Correct answer)
Notify the surgeon immediately
Increase oxygen flow to 6L

Correct answer: Apply jaw thrust and stimulate the patient

Stimulation and airway positioning are the first steps for opioid-related respiratory depression before pharmacologic reversal.

Question 176: Which ASA physical status classification would be assigned to a well-controlled insulin-dependent diabetic patient with no end-organ damage scheduled for ambulatory surgery?

ASA II (Correct answer)
ASA IV
ASA I
ASA III

Correct answer: ASA II

A well-controlled chronic systemic disease without end-organ involvement is classified as ASA II.

Question 177: A patient who received midazolam for procedural sedation wants to sign a consent form for a future procedure before leaving. How should the nurse respond?

Allow signing since the procedure is already over
Advise the patient to wait 24 hours before signing legal documents (Correct answer)
Witness the signature as required by hospital policy
Call the physician to authorize the signing

Correct answer: Advise the patient to wait 24 hours before signing legal documents

Benzodiazepines cause anterograde amnesia and impaired judgment; patients should not sign legal documents for 24 hours post-sedation.

Question 178: A pediatric patient underwent tonsillectomy. Which discharge criterion is MOST specific to this population?

Pain score ≤2/10 on numeric rating scale
Tolerating oral fluids without vomiting
Ability to walk to the car independently
SpO2 ≥95% on room air without stridor (Correct answer)

Correct answer: SpO2 ≥95% on room air without stridor

Post-tonsillectomy pediatric patients must demonstrate airway stability with SpO2 ≥95% on room air and no stridor before discharge.

Question 179: Which nursing action helps prevent hypothermia in the PACU?

Encouraging cold drinks
Limiting movement
Keeping the patient uncovered
Using warm blankets (Correct answer)

Correct answer: Using warm blankets

Providing warm blankets and maintaining ambient temperature support thermoregulation after anesthesia.

Question 180: Which clinical sign BEST differentiates malignant hyperthermia from postoperative fever in the Phase I PACU?

Tachycardia above 100 bpm
Diaphoresis and flushing
Muscle rigidity with masseter spasm and mixed acidosis (Correct answer)
Temperature above 38.5°C

Correct answer: Muscle rigidity with masseter spasm and mixed acidosis

MH is characterized by hypermetabolic crisis with muscle rigidity, masseter spasm, and mixed respiratory and metabolic acidosis — not just elevated temperature.

Question 181: A 68-year-old patient on ACE inhibitors presents for ambulatory knee replacement. Intraoperatively, BP drops to 75/40 despite 1 L LR bolus. The MOST likely cause and treatment is:

Vasoplegic syndrome treated with vasopressors and possibly vasopressin (Correct answer)
Hypovolemia treated with additional fluid boluses only
Cardiac tamponade treated with pericardiocentesis
Anaphylaxis treated with epinephrine

Correct answer: Vasoplegic syndrome treated with vasopressors and possibly vasopressin

ACE inhibitors impair the renin-angiotensin system, causing vasoplegic (distributive) shock refractory to fluids alone, requiring vasopressors.

Question 182: A 4-year-old in the PACU has a temperature of 38.9°C after adenotonsillectomy. The nurse should first:

Administer acetaminophen PR and apply cool cloths
Assess for signs of malignant hyperthermia including muscle rigidity and rising CO2 (Correct answer)
Obtain a blood culture and initiate antibiotic therapy
Notify the surgeon of a likely wound infection

Correct answer: Assess for signs of malignant hyperthermia including muscle rigidity and rising CO2

Any unexplained fever and temperature elevation after volatile anesthesia must first be assessed for malignant hyperthermia, which is a life-threatening emergency requiring immediate intervention.

Question 183: Which PACU alarm condition should prompt the nurse to assess for laryngospasm?

SpO2 drop with wheezing on auscultation
Gradual SpO2 decline with snoring respirations
Sudden SpO2 drop with high-pitched inspiratory stridor and sternal retraction (Correct answer)
SpO2 drop accompanied by diaphoresis and hypertension

Correct answer: Sudden SpO2 drop with high-pitched inspiratory stridor and sternal retraction

Laryngospasm presents with sudden SpO2 drop, high-pitched crowing stridor or complete silence, and sternal retraction due to forceful inspiratory effort against a closed glottis.

Question 184: When is it appropriate to use the 'fast-track' protocol that bypasses Phase I PACU and admits the patient directly to Phase II?

After any laparoscopic procedure under general anesthesia
When the Phase I PACU is at full capacity and staff request expedited transfer
When the patient meets predetermined criteria including an Aldrete-equivalent score ≥ 12 immediately upon OR exit (Correct answer)
After any procedure performed under monitored anesthesia care (MAC)

Correct answer: When the patient meets predetermined criteria including an Aldrete-equivalent score ≥ 12 immediately upon OR exit

Fast-tracking is appropriate only when patients meet validated scoring criteria demonstrating adequate recovery from anesthesia immediately post-procedure, not based on capacity or procedure type alone.

Question 185: Which clinical finding BEST indicates upper airway obstruction in a post-anesthesia patient?

Shallow breathing with bilateral crackles
Tachypnea with accessory muscle use only
Decreased SpO2 with expiratory wheezing
Stridor with paradoxical chest-abdominal movement (Correct answer)

Correct answer: Stridor with paradoxical chest-abdominal movement

Stridor combined with paradoxical (seesaw) chest-abdominal movement is the hallmark of upper airway obstruction, where the diaphragm descends but the airway blockage prevents chest rise.
