CPAN Certification Exam — Questions and Answers

Question 1: A pediatric patient in the PACU after tonsillectomy has a heart rate of 140 bpm, restlessness, and pallor. Which assessment finding would most distinguish postoperative hemorrhage from pain?

Temperature of 37.8°C (100°F)
Presence of blood on the surgical dressing
Frequent swallowing movements and emesis of dark red material (Correct answer)
Complaint of throat pain rated 8/10

Correct answer: Frequent swallowing movements and emesis of dark red material

Frequent swallowing and emesis of dark blood after tonsillectomy are hallmark signs of post-tonsillectomy hemorrhage with the child swallowing pooled blood.

Question 2: Why is having expertise in monitoring vital signs critical for a CPAN?

It ensures proper dosing of anesthesia
It allows for early detection of complications such as low blood pressure or oxygen saturation (Correct answer)
It improves communication with patients' families
It helps to identify when to perform surgery

Correct answer: It allows for early detection of complications such as low blood pressure or oxygen saturation

Vigilant monitoring and expert interpretation of vital signs are fundamental to a CPAN's role. Early detection of deviations like hypotension, hypoxemia, or arrhythmias enables prompt intervention, preventing serious complications and ensuring patient stability during the critical post-anesthesia period.

Question 3: What is the PACU nurse's primary role in patient-controlled analgesia (PCA) management?

Educating the patient on proper PCA use and monitoring for side effects (Correct answer)
Disabling the lockout mechanism for patients with severe pain
Pressing the PCA button for the patient when they appear uncomfortable
Setting the medication dose independently without an order

Correct answer: Educating the patient on proper PCA use and monitoring for side effects

The PACU nurse educates patients on correct PCA use and monitors for complications including respiratory depression and inadequate pain control.

Question 4: Which set of conditions is REQUIRED for effective steam sterilization (autoclave) of surgical instruments?

134°C temperature, 30 psi pressure, 5-minute exposure time
115°C temperature, 10 psi pressure, 30-minute exposure time
121°C temperature, 15 psi pressure, 15–30 minute exposure time (Correct answer)
100°C temperature, atmospheric pressure, 60-minute exposure time

Correct answer: 121°C temperature, 15 psi pressure, 15–30 minute exposure time

Standard steam sterilization (gravity displacement autoclave) requires 121°C, 15 psi, for 15–30 minutes to achieve sterility by destroying all microbial life including spores.

Question 5: A patient in the PACU becomes tearful and says, 'I just want to go home.' The MOST therapeutic response is:

'I'll call your family to let them know you're ready.'
'You'll be home before you know it — just relax.'
'You need to meet discharge criteria first, so let's focus on that.'
'I hear that you want to go home. Can you tell me more about how you're feeling right now?' (Correct answer)

Correct answer: 'I hear that you want to go home. Can you tell me more about how you're feeling right now?'

Empathetic reflection followed by an open-ended question invites the patient to share feelings and identifies unmet needs.

Question 6: Which temperature monitoring site provides the most accurate reflection of core body temperature in PACU patients?

Temporal artery
Pulmonary artery (PA catheter) (Correct answer)
Axillary
Oral

Correct answer: Pulmonary artery (PA catheter)

PA catheter temperature directly measures blood in the central circulation and is the gold standard for core temperature, though less practical; esophageal and nasopharyngeal are close alternatives in clinical settings.

Question 7: Which warming method is considered most effective for treating mild to moderate post-operative hypothermia in the PACU?

Forced-air warming devices (Correct answer)
Radiant heat lamps
Warm blankets alone
Warm IV fluids only

Correct answer: Forced-air warming devices

Forced-air warming devices (e.g., Bair Hugger) are the most effective active external warming method for treating post-operative hypothermia.

Question 8: A PACU nurse notes a patient has bradycardia following reversal of neuromuscular blockade. Glycopyrrolate was used instead of atropine. What advantage does glycopyrrolate offer?

Crosses the blood-brain barrier to cause central effects
Has a faster onset than atropine
Does not cross the blood-brain barrier, avoiding CNS side effects like confusion (Correct answer)
Is more effective at reversing severe bradycardia

Correct answer: Does not cross the blood-brain barrier, avoiding CNS side effects like confusion

Glycopyrrolate is a quaternary ammonium compound that does not cross the blood-brain barrier, avoiding CNS anticholinergic effects such as confusion, sedation, or delirium seen with atropine.

Question 9: A postoperative patient receives metoclopramide for PONV. Which serious adverse effect must the nurse monitor for?

Hypertensive crisis
Hyperglycemia
Extrapyramidal symptoms (Correct answer)
Bronchospasm

Correct answer: Extrapyramidal symptoms

Metoclopramide is a dopamine antagonist that can cause extrapyramidal side effects including akathisia, dystonia, and tardive dyskinesia, especially with repeated dosing.

Question 10: For non-invasive continuous temperature monitoring in PACU patients, which site is considered the most accurate accessible alternative to pulmonary artery measurement?

Oral
Tympanic membrane (Correct answer)
Rectal
Axillary

Correct answer: Tympanic membrane

Tympanic membrane temperature closely reflects core (hypothalamic) temperature through its shared blood supply with the brain and is a practical, accurate non-invasive site.

Question 11: A Phase II PACU patient is being prepared for home discharge after outpatient laparoscopic surgery. Which discharge instruction is MOST critical for patient safety?

Return to work the next business day
Do not drive or operate machinery for 24 hours after anesthesia (Correct answer)
Resume a full diet immediately upon arriving home
Avoid strenuous exercise for 6 weeks

Correct answer: Do not drive or operate machinery for 24 hours after anesthesia

Residual anesthetic and sedative effects impair psychomotor function for up to 24 hours; driving prohibition is a mandatory patient safety instruction after general or sedation anesthesia.

Question 12: During the handoff from the OR, the anesthesiologist reports the patient received 300 mg of succinylcholine for a difficult intubation. Four hours later the patient remains apneic. The most likely explanation is:

Opioid-induced respiratory depression
Residual non-depolarizing blockade
Pseudocholinesterase deficiency (Correct answer)
Malignant hyperthermia

Correct answer: Pseudocholinesterase deficiency

Pseudocholinesterase (butyrylcholinesterase) deficiency impairs succinylcholine metabolism, resulting in prolonged neuromuscular blockade lasting hours.

Question 13: A PACU patient has shallow respirations and a tidal volume of 3 mL/kg after general anesthesia. What is the likely cause?

Acute bronchospasm
Metabolic alkalosis from excessive bicarbonate
Residual neuromuscular blockade causing inadequate respiratory effort (Correct answer)
Fluid overload causing pulmonary edema

Correct answer: Residual neuromuscular blockade causing inadequate respiratory effort

Residual neuromuscular blockade from non-depolarizing muscle relaxants is a common cause of inadequate tidal volumes and respiratory weakness post-anesthesia.

Question 14: Hypothermia impairs drug metabolism in the PACU primarily by affecting which organ's enzymatic function?

Kidneys
Liver (Correct answer)
Spleen
Lungs

Correct answer: Liver

The liver's cytochrome P450 enzymes are temperature-sensitive; hypothermia slows hepatic metabolism, prolonging the duration of many anesthetic and analgesic drugs.

Question 15: In electronic health records (EHR) used in the PACU, which practice BEST protects patient data security?

Using the same password across multiple systems for easy recall
Logging out or locking the workstation when stepping away, even briefly (Correct answer)
Allowing family members to view the EHR at the bedside
Sharing login credentials with trusted colleagues during busy periods

Correct answer: Logging out or locking the workstation when stepping away, even briefly

Logging out or locking workstations prevents unauthorized access and protects patient privacy in compliance with HIPAA.

Question 16: A post-anesthesia patient in the PACU has an SpO2 of 88% on room air. What is the nurse's first intervention?

Call a code blue immediately
Apply supplemental oxygen and stimulate the patient to breathe deeply (Correct answer)
Administer IV epinephrine
Obtain an arterial blood gas immediately

Correct answer: Apply supplemental oxygen and stimulate the patient to breathe deeply

The first response to low SpO2 is applying supplemental oxygen and stimulating the patient to take deep breaths, as residual anesthesia frequently causes hypoventilation.

Question 17: A 72-year-old patient in the PACU becomes increasingly confused, hypertensive, and complains of a severe headache following elective hip replacement. Which urgent assessment should the nurse perform first?

Check blood glucose level
Assess for urinary retention
Perform a focused neurological assessment (Correct answer)
Review the intraoperative fluid balance

Correct answer: Perform a focused neurological assessment

Sudden severe headache with hypertension and altered mental status may indicate intracerebral hemorrhage or hypertensive emergency, requiring immediate neurological assessment.

Question 18: What is the purpose of the Aldrete Score in PACU discharge planning?

To determine appropriate post-operative medication dosing
To assess only the patient's current pain level before discharge
To assess surgical wound healing and readiness for staple removal
To objectively evaluate recovery using criteria including activity, respiration, circulation, consciousness, and oxygen saturation (Correct answer)

Correct answer: To objectively evaluate recovery using criteria including activity, respiration, circulation, consciousness, and oxygen saturation

The Aldrete Score is a standardized scoring system used to objectively determine when a patient is physiologically ready for discharge from Phase I PACU recovery.

Question 19: A patient exhibits agitation, diaphoresis, hypertension, and muscle twitching 2 hours after receiving meperidine and a serotonergic antidepressant. Which condition should the nurse suspect?

Malignant hyperthermia
Serotonin syndrome (Correct answer)
Anticholinergic crisis
Neuroleptic malignant syndrome

Correct answer: Serotonin syndrome

Serotonin syndrome results from excess serotonergic activity and is precipitated by combining opioids like meperidine with serotonergic drugs.

Question 20: A patient in the PACU after exploratory laparotomy has a nasogastric tube draining 400 mL of bright red blood in 30 minutes. Which assessment should the PACU nurse perform immediately?

Check the surgical site dressing for external bleeding
Irrigate the NG tube with normal saline to confirm placement
Obtain a STAT hemoglobin and hematocrit level
Assess blood pressure, heart rate, and level of consciousness (Correct answer)

Correct answer: Assess blood pressure, heart rate, and level of consciousness

Rapid assessment of hemodynamic status (blood pressure, heart rate, consciousness) identifies the degree of hemorrhagic compromise and guides urgency of escalation.

Question 21: What is the primary responsibility of a Certified Post Anesthesia Nurse (CPAN) in the post-anesthesia care unit (PACU)?

Administering anesthesia
Assisting with pre-anesthesia preparation
Performing surgery
Monitoring the patient's recovery from anesthesia (Correct answer)

Correct answer: Monitoring the patient's recovery from anesthesia

The primary role of a Certified Post Anesthesia Nurse (CPAN) is to provide specialized care to patients immediately following surgery or a procedure requiring anesthesia. This involves vigilant monitoring of vital signs, assessing for complications, and managing pain as the patient emerges from anesthesia in the Post-Anesthesia Care Unit (PACU).

Question 22: What is post-operative cognitive dysfunction (POCD) and which patient population is at greatest risk?

A cognitive condition that exclusively affects pediatric surgical patients
A planned sedation effect that affects all age groups equally
A decline in cognitive function persisting after surgery that is most common in elderly patients (Correct answer)
A permanent and irreversible condition affecting all surgical patients uniformly

Correct answer: A decline in cognitive function persisting after surgery that is most common in elderly patients

POCD is a decline in cognitive function that can persist after surgery, with elderly patients at significantly higher risk due to age-related neurologic vulnerabilities.

Question 23: What is the first-line pharmacological treatment for a confirmed case of malignant hyperthermia?

Propranolol
Diazepam
Sodium bicarbonate
Dantrolene sodium (Correct answer)

Correct answer: Dantrolene sodium

Dantrolene sodium is the specific antidote for MH, acting by inhibiting calcium release from the sarcoplasmic reticulum in skeletal muscle.

Question 24: Which assessment scale is specifically designed for pain assessment in non-verbal PACU patients?

Wong-Baker FACES Scale
Behavioral Pain Scale (BPS) (Correct answer)
McGill Pain Questionnaire
Visual Analog Scale (VAS)

Correct answer: Behavioral Pain Scale (BPS)

The Behavioral Pain Scale assesses pain based on observable behaviors such as facial expression, body movements, and ventilator compliance in patients who cannot self-report.

Question 25: In which situation would a PACU nurse be REQUIRED to file a mandatory report despite patient confidentiality protections?

A patient discloses current physical abuse by a household member (Correct answer)
A patient refuses postoperative medications
A patient admits to recreational marijuana use in a state where it is legal
A patient requests a second opinion from another physician

Correct answer: A patient discloses current physical abuse by a household member

Mandatory reporting laws require nurses to report suspected or confirmed abuse regardless of patient confidentiality, as public safety supersedes privacy protections.

Question 26: What is bronchospasm in the post-anesthesia setting and how is it treated?

Expected adventitious breath sounds heard routinely after endotracheal intubation
Airway secretions that are resolved with suctioning alone
Bronchial smooth muscle contraction causing airway narrowing, treated with bronchodilators such as albuterol (Correct answer)
A completely normal physiologic response to extubation requiring no treatment

Correct answer: Bronchial smooth muscle contraction causing airway narrowing, treated with bronchodilators such as albuterol

Bronchospasm is a sudden narrowing of the bronchi from smooth muscle contraction and is treated with bronchodilators such as albuterol along with supplemental oxygen.

Question 27: Which of the following is the MOST accurate statement about the nurse's legal responsibility regarding documentation of patient teaching in the PACU?

Teaching documentation is optional if the patient is discharged quickly
Teaching only needs to be documented if the patient asks questions
The nurse must document the content taught, teaching method used, patient's demonstrated understanding, and any barriers to learning (Correct answer)
Verbal confirmation from the patient is sufficient without written documentation

Correct answer: The nurse must document the content taught, teaching method used, patient's demonstrated understanding, and any barriers to learning

Complete discharge teaching documentation must include content, method, learner response, and barriers to demonstrate that safe discharge education was provided.

Question 28: What is the correct order for donning personal protective equipment (PPE)?

Gloves, gown, mask, goggles
Mask, gloves, gown, goggles
Goggles, gloves, mask, gown
Gown, mask, goggles, gloves (Correct answer)

National Council of State Boards of Nursing (NCSBN)
American Nurses Association (ANA)

Correct answer: American Board of Perianesthesia Nursing Certification (ABPANC)

The American Board of Perianesthesia Nursing Certification (ABPANC) is the sole organization dedicated to certifying perianesthesia nurses, including the CPAN credential. ABPANC establishes the standards, develops the exams, and maintains the integrity of these specialized nursing certifications.

Question 30: Dexmedetomidine exerts its sedative and analgesic effects primarily through which receptor?

NMDA receptor
Mu opioid receptor
Alpha-2 adrenergic receptor (Correct answer)
GABA-A receptor

Correct answer: Alpha-2 adrenergic receptor

Dexmedetomidine is a highly selective alpha-2 adrenergic agonist that produces sedation, analgesia, and anxiolysis with minimal respiratory depression.

Question 31: A PACU nurse notes that a patient has an end-tidal CO2 (EtCO2) waveform that is gradually rising. What does this finding indicate?

Normal variation with no clinical significance
Hypoventilation with CO2 retention (Correct answer)
Improving ventilation and adequate CO2 elimination
Oxygen toxicity

Correct answer: Hypoventilation with CO2 retention

A rising EtCO2 trend indicates increasing CO2 retention from hypoventilation, requiring assessment and intervention to improve respiratory effort.

Question 32: Which element is MOST critical to include when documenting a patient's consent for a procedure in the PACU?

The family member who witnessed the consent process
Confirmation that consent was obtained preoperatively by the surgeon (Correct answer)
The nurse's assessment of patient competency at time of consent
The specific risks and benefits discussed with the patient

Correct answer: Confirmation that consent was obtained preoperatively by the surgeon

PACU nurses verify and document that informed consent was obtained preoperatively; they do not obtain new surgical consent in the PACU.

Question 33: What is the difference between a side effect and an adverse reaction?

Adverse reactions only occur with overdoses
Side effects are expected; adverse reactions are harmful and unexpected (Correct answer)
They are identical terms
Side effects are more serious than adverse reactions

Correct answer: Side effects are expected; adverse reactions are harmful and unexpected

Side effects are predictable secondary effects, while adverse reactions are unexpected harmful responses to medication.

Question 34: Which non-pharmacologic intervention is appropriate for mild to moderate pain in the PACU?

Intravenous fentanyl
Patient positioning and cold therapy (Correct answer)
Ketamine infusion
Epidural analgesia

Correct answer: Patient positioning and cold therapy

Non-pharmacologic interventions such as proper positioning and cold or heat therapy can complement pharmacologic pain management in the PACU.

Question 35: A patient develops hypotension 30 minutes after surgery. What is the PACU nurse's priority action?

Assess for the underlying cause, notify the physician, and initiate appropriate interventions based on findings (Correct answer)
Immediately administer vasopressors without physician notification
Document the finding and wait for spontaneous resolution
Increase the IV fluid rate to maximum without first notifying the physician

Correct answer: Assess for the underlying cause, notify the physician, and initiate appropriate interventions based on findings

Post-operative hypotension requires prompt systematic assessment to identify the underlying cause before appropriate targeted treatment can be initiated, with timely physician notification.

Question 36: How long must professional records typically be maintained?

Only until the patient is discharged
Until the file cabinet is full
According to state and federal regulations, often 7-10 years or longer (Correct answer)
For exactly one calendar year

Correct answer: According to state and federal regulations, often 7-10 years or longer

Record retention is governed by state and federal laws, with most requiring 7-10 years, and longer for minors.

Question 37: A patient with an implanted cardiac defibrillator (ICD) develops ventricular fibrillation in the PACU and the ICD fails to fire. The nurse should:

Begin CPR and use the external defibrillator, placing pads away from the ICD generator (Correct answer)
Avoid external defibrillation due to risk of ICD damage
Place defibrillator pads directly over the ICD to maximize energy delivery
Wait 30 seconds for the ICD to recharge before external defibrillation

Correct answer: Begin CPR and use the external defibrillator, placing pads away from the ICD generator

External defibrillation should proceed immediately; pads should be placed at least 8 cm from the ICD generator to avoid damaging the device.

Question 38: Which factor most significantly affects the reliability of assessment findings?

The color of assessment forms used
The size of the examination room
Standardized procedures and consistent methodology (Correct answer)
The time of day the assessment is performed

Correct answer: Standardized procedures and consistent methodology

Using standardized procedures and consistent methodology ensures reliable, reproducible assessment findings across different practitioners.

Question 39: What are early clinical signs of post-operative hemorrhage that a PACU nurse must monitor for?

Stable vital signs and minimal wound drainage throughout recovery
Increasing heart rate, falling blood pressure, and increased wound drainage (Correct answer)
Hypertension and bradycardia with stable wound drainage
Fever with flushing and warm extremities

Correct answer: Increasing heart rate, falling blood pressure, and increased wound drainage

Early hemorrhage signs include tachycardia, hypotension, and increasing wound drainage, all of which require immediate notification of the surgical team.

Question 40: A post-anesthesia patient asks the nurse, 'Did they find anything bad during my surgery?' The surgeon has not yet spoken to the patient. The MOST appropriate nursing response is:

'Your surgeon found some concerning findings — I'll let them explain.'
'I'll make sure your surgeon comes to speak with you about the surgical findings as soon as possible.' (Correct answer)
'I'm not allowed to discuss surgical findings at all.'
'Everything went smoothly — don't worry.'

Correct answer: 'I'll make sure your surgeon comes to speak with you about the surgical findings as soon as possible.'

The nurse should facilitate communication with the surgeon while avoiding disclosure of findings that are the physician's responsibility to convey.

Question 41: Propofol infusion syndrome (PRIS) is most associated with which clinical finding?

Prolonged QT interval
Hyperglycemia
Hyperkalemia alone
Severe metabolic acidosis with cardiac failure (Correct answer)

Correct answer: Severe metabolic acidosis with cardiac failure

PRIS is characterized by severe metabolic (lactic) acidosis, rhabdomyolysis, cardiac failure, and renal failure, typically occurring with high-dose prolonged propofol infusions.

Question 42: Which PACU nursing intervention MOST directly reduces the risk of ventilator-associated pneumonia (VAP) in a mechanically ventilated patient?

Maintaining head-of-bed elevation at 30–45 degrees (Correct answer)
Using heated humidification in the ventilator circuit
Suctioning the airway every hour on a scheduled basis
Administering prophylactic antibiotics every six hours

Correct answer: Maintaining head-of-bed elevation at 30–45 degrees

Elevating the head of the bed 30–45 degrees is a core VAP bundle intervention that reduces aspiration of oropharyngeal secretions into the lower respiratory tract.

Question 43: Which of the following correctly describes the mechanism of ondansetron in preventing postoperative nausea and vomiting (PONV)?

Serotonin 5-HT3 receptor antagonist (Correct answer)
Histamine H1 receptor antagonist
Muscarinic M1 receptor antagonist
Dopamine D2 receptor antagonist

Correct answer: Serotonin 5-HT3 receptor antagonist

Ondansetron blocks 5-HT3 (serotonin) receptors in the gut and CTZ, making it one of the most effective agents for PONV prophylaxis and treatment.

Question 44: What is a drug contraindication?

A drug interaction that enhances effectiveness
A condition that makes a particular treatment inadvisable (Correct answer)
A reason to increase the dosage
A type of allergic reaction

Correct answer: A condition that makes a particular treatment inadvisable

A contraindication is a specific situation where a drug should not be used because it may cause harm.

Question 45: A PACU nurse notes that a patient's Foley catheter has had no output for 90 minutes post-operatively. After confirming catheter patency, the priority nursing action is:

Assess fluid balance and notify the anesthesia provider (Correct answer)
Administer furosemide 40 mg IV
Place patient in Trendelenburg position to improve renal perfusion
Encourage oral fluid intake to stimulate diuresis

Correct answer: Assess fluid balance and notify the anesthesia provider

Oliguria in the PACU may reflect inadequate fluid resuscitation, hypoperfusion, or surgical complications and requires provider notification after ensuring catheter function.

Question 46: What does the acronym AED stand for?

Advanced Emergency Device
Automated Electrical Diagnostic
Advanced External Decompressor
Automated External Defibrillator (Correct answer)

Correct answer: Automated External Defibrillator

An AED (Automated External Defibrillator) analyzes heart rhythm and delivers an electrical shock if needed to restore normal rhythm.

Question 47: A CPAN is managing a patient with epidural analgesia for post-thoracotomy pain. The nurse notes the patient has bilateral lower extremity weakness and urinary retention. The priority action is:

Stop the epidural infusion and notify the anesthesia provider immediately (Correct answer)
Encourage ambulation to test motor recovery
Administer a fluid bolus and monitor blood pressure
Reduce the epidural rate by 50% and reassess in one hour

Correct answer: Stop the epidural infusion and notify the anesthesia provider immediately

New bilateral weakness and urinary retention may indicate epidural hematoma or excessive local anesthetic spread, both emergencies requiring immediate provider notification.

Question 48: A PACU patient who received regional anesthesia develops sudden cardiovascular collapse. Lipid emulsion therapy is initiated. For which drug toxicity is this treatment indicated?

Benzodiazepine overdose
Local anesthetic systemic toxicity (LAST) (Correct answer)
Acetaminophen toxicity
Opioid overdose

Correct answer: Local anesthetic systemic toxicity (LAST)

Intravenous lipid emulsion (Intralipid) acts as a 'lipid sink,' sequestering lipid-soluble local anesthetics like bupivacaine from cardiac and CNS tissue to treat LAST.

Question 49: A patient in the PACU develops hypotension following spinal anesthesia. Which vasopressor is the first-line agent for spinal-induced hypotension in obstetric patients?

Epinephrine
Phenylephrine (Correct answer)
Norepinephrine
Dopamine

Correct answer: Phenylephrine

Phenylephrine is the preferred first-line vasopressor for spinal-induced hypotension in obstetrics because it maintains uteroplacental blood flow better than ephedrine.

Question 50: A patient in the PACU who received ketamine as part of the anesthetic reports seeing frightening visions and is extremely agitated. The most appropriate assessment priority is:

Assess the environment for excessive stimulation
Assess for concurrent emergence delirium from volatile anesthetics
Rule out hypoxia and hypercapnia as contributing factors before treating (Correct answer)
Administer midazolam and reassess in 5 minutes

Correct answer: Rule out hypoxia and hypercapnia as contributing factors before treating

Before attributing symptoms to ketamine dysphoria, hypoxia and hypercapnia must be ruled out as they can cause identical presentations and require different treatment.

Question 51: A post-anesthesia patient refuses to use the incentive spirometer despite instruction. Which communication approach is MOST effective?

Tell the patient it is required and document refusal
Demonstrate the device again without asking for feedback
Defer respiratory care until the patient agrees
Explore the reason for refusal and address barriers before re-educating (Correct answer)

Correct answer: Explore the reason for refusal and address barriers before re-educating

Identifying and addressing barriers to compliance is more effective than repeating instructions or documenting refusal without exploration.

Question 52: When explaining discharge instructions to a drowsy post-anesthesia patient, which timing principle is MOST important?

Complete teaching before Aldrete score reaches 9
Deliver instructions only when the patient is fully alert and oriented (Correct answer)
Provide all instructions immediately upon PACU arrival
Give instructions to the family only, not the patient

Correct answer: Deliver instructions only when the patient is fully alert and oriented

Residual anesthesia impairs cognition and memory retention, so discharge teaching must occur when the patient is fully alert.

Question 53: What is opioid tolerance and how does it affect post-anesthesia pain management?

An allergy to opioid medications requiring avoidance
A contraindication to opioid use in the post-operative setting
Decreased analgesic effect requiring higher doses to achieve the same pain relief (Correct answer)
The ability to metabolize opioids more rapidly than average

Correct answer: Decreased analgesic effect requiring higher doses to achieve the same pain relief

Opioid tolerance occurs when repeated exposure to opioids reduces analgesic effect, requiring higher doses to achieve the same level of pain relief.

Question 54: A post-anesthesia patient has a respiratory rate of 8 breaths/min and SpO2 of 88% on room air. After applying 6L/min oxygen via face mask, SpO2 rises to 94%. What is the most likely cause of initial hypoxemia?

Pneumothorax
Pulmonary embolism
Bronchospasm
Hypoventilation from residual opioid effect (Correct answer)

Correct answer: Hypoventilation from residual opioid effect

A slow respiratory rate with improvement on supplemental oxygen suggests opioid-induced hypoventilation, the most common cause of post-anesthesia hypoxemia.

Question 55: A patient in the PACU develops severe bronchospasm unresponsive to two doses of albuterol. The anesthesiologist orders magnesium sulfate. What is the primary mechanism by which magnesium relieves bronchospasm?

Inhibits mast cell degranulation
Blocks calcium-mediated smooth muscle contraction (Correct answer)
Reduces airway mucosal edema
Stimulates beta-2 adrenergic receptors

Correct answer: Blocks calcium-mediated smooth muscle contraction

Magnesium sulfate acts as a calcium antagonist, inhibiting calcium-mediated smooth muscle contraction and thereby causing bronchodilation.

Question 56: According to ASPAN staffing guidelines, what is the minimum nurse-to-patient ratio for a Phase I PACU patient who is critically ill and unstable?

1:1 with a second nurse immediately available (Correct answer)
1:2
2:1 nursing staff to one patient
1:1 at all times without exception

Correct answer: 1:1 with a second nurse immediately available

ASPAN standards require a 1:1 ratio for unstable Phase I patients with a second nurse immediately available to assist.

Question 57: When assessing a patient for readiness to bypass Phase I recovery (Fast-Track criteria), the CPAN should confirm the patient has:

A modified Aldrete score of ≥9 with stable vital signs and no complications (Correct answer)
A Numeric Rating Scale pain score of 0
Voided at least 200 mL urine spontaneously
Completed at least 2 hours in Phase I recovery

Correct answer: A modified Aldrete score of ≥9 with stable vital signs and no complications

Fast-track eligibility requires a modified Aldrete score of ≥9, indicating adequate recovery of activity, breathing, circulation, consciousness, and oxygenation.

Question 58: What is multimodal analgesia in the post-anesthesia setting?

Using only IV opioids for pain control
Using only non-pharmacologic methods
Administering the maximum dose of a single analgesic
Combining different analgesic medications targeting different pain pathways (Correct answer)

Correct answer: Combining different analgesic medications targeting different pain pathways

Multimodal analgesia combines different analgesic classes targeting different pain mechanisms to improve pain control while reducing opioid requirements.

Question 59: How does post-operative atelectasis typically present in the PACU?

Markedly increased urine output with normal respiratory status
Decreased breath sounds, reduced oxygen saturation, and possible fever (Correct answer)
Complete absence of symptoms with normal oxygen saturation
Hypertension and bradycardia with intact breath sounds

Correct answer: Decreased breath sounds, reduced oxygen saturation, and possible fever

Post-operative atelectasis presents with decreased or absent breath sounds in affected lung areas, reduced oxygen saturation, and possible fever from lung collapse.

Question 60: After administering IV morphine to a PACU patient, the nurse notes respiratory rate of 8 breaths/min and SpO2 of 89%. The nurse's responsibility includes:

Stimulating the patient, applying oxygen, and preparing naloxone per protocol (Correct answer)
Repositioning the patient and reassessing in 5 minutes
Calling the anesthesiologist and waiting for orders before intervening
Documenting the findings and continuing to monitor every 15 minutes

Correct answer: Stimulating the patient, applying oxygen, and preparing naloxone per protocol

Respiratory depression after opioid administration requires immediate intervention including stimulation, oxygen, and readiness to administer naloxone.

Question 61: A patient asks why they feel so cold after surgery. Which response BEST demonstrates therapeutic communication?

'It's just a side effect you'll have to tolerate for a while.'
'Anesthesia and the cool OR environment lower your body temperature; we are warming you now.' (Correct answer)
'Don't worry about it; we have a warm blanket for you.'
'Everyone feels that way — it's normal.'

Correct answer: 'Anesthesia and the cool OR environment lower your body temperature; we are warming you now.'

Providing a brief, honest explanation addresses the patient's concern and reduces anxiety while demonstrating professional competence.

Question 62: What is the primary purpose of thorough documentation in professional practice?

To create an accurate record for continuity of care and legal protection (Correct answer)
To demonstrate writing ability
To fill time during slow periods
To satisfy administrative preferences only

Correct answer: To create an accurate record for continuity of care and legal protection

Documentation serves as the legal record of services provided and ensures continuity of care among providers.

Question 63: When assessing an epidural catheter in the PACU, the nurse notes the patient has no sensation or motor function below T4. The nurse's priority intervention is:

Administer naloxone to reverse opioid effects
Document the finding as expected after epidural placement
Stop the epidural infusion and notify the anesthesia provider (Correct answer)
Increase the epidural infusion rate to maintain analgesia

Correct answer: Stop the epidural infusion and notify the anesthesia provider

A high spinal or epidural block above T4 can compromise respiratory function and hemodynamic stability, requiring immediate cessation of the infusion and anesthesia notification.

Question 64: A PACU nurse discovers a documentation error in a paper medical record. What is the correct method to correct the error?

Completely cross out the error with multiple lines so it is unreadable
Use correction fluid (white-out) to cover the error and write the correct information
Remove the page and rewrite the entire note correctly
Draw a single line through the error, write the correction, and add initials, date, and 'error' notation (Correct answer)

Correct answer: Draw a single line through the error, write the correction, and add initials, date, and 'error' notation

The legally correct method is a single line through the error with correction, initials, date, and error notation to maintain record integrity.

Question 65: How should a PACU nurse objectively assess for post-operative hypothermia?

Rely solely on the patient's subjective complaint of feeling cold
Rely on visual inspection of skin color as the primary assessment method
Ask the patient whether they feel cold and accept their answer
Monitor core temperature with a reliable thermometer and assess for shivering and vital sign changes (Correct answer)

Correct answer: Monitor core temperature with a reliable thermometer and assess for shivering and vital sign changes

Post-operative hypothermia assessment requires objective core temperature measurement in conjunction with clinical signs such as shivering, pallor, and hemodynamic changes.

Question 66: What is the correct compression-to-ventilation ratio for single-rescuer adult CPR?

30 compressions to 1 ventilation
15 compressions to 1 ventilation
30 compressions to 2 ventilations (Correct answer)
15 compressions to 2 ventilations

Question 129: What does the term "half-life" refer to in pharmacology?

The time between two doses
The point at which a drug reaches maximum effectiveness
The time until the drug expires
The time it takes for the drug concentration to decrease by 50% (Correct answer)

Correct answer: The time it takes for the drug concentration to decrease by 50%

Half-life is the time required for the plasma concentration of a drug to decrease by one-half, affecting dosing schedules.

Question 130: Which factors should guide the PACU nurse's choice of pain management approach?

The hospital formulary list only
Type of surgery, patient's medical history, allergies, and pain assessment findings (Correct answer)
Patient's age only
The surgeon's stated preference only

Correct answer: Type of surgery, patient's medical history, allergies, and pain assessment findings

Pain management must be individualized based on multiple factors including procedure type, medical history, allergies, and current pain assessment data.

Question 131: A post-thyroidectomy patient in the PACU develops inspiratory stridor, dysphagia, and neck swelling. The nurse's immediate priority is:

Prepare for emergency airway management and alert the surgeon (Correct answer)
Administer calcium gluconate 1 g IV
Elevate the head of bed and administer supplemental oxygen
Apply an ice collar to reduce swelling

Correct answer: Prepare for emergency airway management and alert the surgeon

Post-thyroidectomy stridor with neck swelling suggests hematoma-induced airway compromise, which is a surgical emergency requiring immediate airway preparation and surgeon notification.

Question 132: In addition to monitoring vital signs, which of the following is an important responsibility for a CPAN during the post-anesthesia recovery phase?

Performing pre-operative assessments
Assessing for signs of anesthesia complications (Correct answer)
Administering post-surgery medication
Coordinating surgery schedules

Correct answer: Assessing for signs of anesthesia complications

Beyond routine vital sign monitoring, a CPAN's critical responsibility is to proactively assess for and identify potential complications stemming from anesthesia. These can include respiratory depression, cardiovascular instability, nausea, vomiting, or delayed emergence, requiring prompt recognition and intervention to ensure patient safety.

Question 133: Which of the following represents the most appropriate pain reassessment interval after administering IV opioid analgesia in Phase I PACU?

At the time of transfer to Phase II recovery
Only when the patient requests reassessment
60 minutes after administration
15–30 minutes or at peak effect of the medication (Correct answer)

Correct answer: 15–30 minutes or at peak effect of the medication

Reassessing pain at peak effect (typically 15–30 minutes for IV opioids) allows the nurse to evaluate treatment efficacy and plan further interventions safely.

Question 134: What is the first action to take in any emergency situation?

Begin CPR immediately
Ensure scene safety and assess the situation (Correct answer)
Move the victim to another location
Call for advanced medical help first

Correct answer: Ensure scene safety and assess the situation

Scene safety assessment is always the first priority to prevent additional injuries to rescuers and bystanders.

Question 135: Which nursing intervention best prevents post-operative atelectasis in PACU patients?

Administering prophylactic bronchodilators to all patients
Encouraging incentive spirometry and deep breathing exercises every 1-2 hours (Correct answer)
Restricting fluid intake to minimize pulmonary edema
Keeping patients supine to minimize respiratory effort

Correct answer: Encouraging incentive spirometry and deep breathing exercises every 1-2 hours

Regular incentive spirometry and deep breathing promote alveolar recruitment and prevent atelectasis, which is common after general anesthesia due to reduced functional residual capacity.

Question 136: How does the PACU nurse differentiate between hypoxemia caused by hypoventilation versus ventilation-perfusion (V/Q) mismatch?

Both conditions respond identically to supplemental oxygen
Hypoventilation causes hypoxemia with normal CO2; V/Q mismatch causes hypoxemia with elevated CO2
Hypoventilation improves with 100% oxygen alone; V/Q mismatch does not reliably correct with oxygen alone and is associated with elevated CO2 (Correct answer)
V/Q mismatch causes hypercapnia; hypoventilation does not affect CO2

Correct answer: Hypoventilation improves with 100% oxygen alone; V/Q mismatch does not reliably correct with oxygen alone and is associated with elevated CO2

Hypoventilation causes hypoxemia with elevated CO2 that responds to increasing ventilation, while V/Q mismatch (e.g., atelectasis, PE) may not fully correct with oxygen alone.

Question 137: What is the underlying cause of post-operative shivering and how should a PACU nurse manage it?

A sign of infection requiring immediate antibiotic administration
A sign of anesthetic overdose requiring emergency reversal agents
A completely normal finding requiring no assessment or intervention
A thermoregulatory response to hypothermia managed with warming blankets and warm IV fluids (Correct answer)

Correct answer: A thermoregulatory response to hypothermia managed with warming blankets and warm IV fluids

Post-operative shivering is most often caused by hypothermia acquired during surgery and is managed with active warming measures including warm blankets and warmed IV fluids.

Question 138: What is post-operative ileus and how does it present clinically?

Normal audible bowel sounds returning within 2 hours of any surgery
Temporary cessation of bowel peristalsis presenting with absent bowel sounds, nausea, and abdominal distension (Correct answer)
An intestinal infection acquired during or after the surgical procedure
A post-operative complication that only occurs in pediatric patients after abdominal surgery

Correct answer: Temporary cessation of bowel peristalsis presenting with absent bowel sounds, nausea, and abdominal distension

Post-operative ileus is a temporary cessation of bowel peristalsis common after abdominal surgery, presenting with absent bowel sounds, abdominal distension, and inability to tolerate oral intake.

Question 139: A PACU patient develops sudden onset shivering after general anesthesia. The CPAN understands this increases:

Likelihood of delayed emergence
Oxygen consumption by up to 400% (Correct answer)
Serum potassium levels
Risk of aspiration

Correct answer: Oxygen consumption by up to 400%

Post-anesthesia shivering dramatically increases metabolic oxygen demand, which can be dangerous in patients with cardiac or respiratory compromise.

Question 140: What critical thinking skill is most important for a Certified Post Anesthesia Nurse when dealing with a rapidly changing patient condition?

Ability to calculate medication dosages
Ability to recognize and act on signs of complications quickly (Correct answer)
Ability to delegate tasks to others
Ability to educate the family about anesthesia

Correct answer: Ability to recognize and act on signs of complications quickly

In the PACU, patient conditions can change rapidly and unexpectedly, making the ability to quickly identify and respond to complications paramount. A CPAN must possess keen critical thinking skills to interpret subtle changes in patient status and initiate timely, appropriate interventions to prevent adverse outcomes.

Question 141: A patient who had general anesthesia reports nausea and vomits 150 mL in the PACU. Which intervention is LEAST appropriate as a first-line response?

Turn the patient to the lateral position to prevent aspiration
Administer ondansetron 4 mg IV per protocol
Administer metoclopramide to promote gastric motility
Administer promethazine 25 mg IV push (Correct answer)

Correct answer: Administer promethazine 25 mg IV push

Promethazine IV push is associated with severe tissue injury and is contraindicated via this route; ondansetron and metoclopramide are safer first-line antiemetics.

Question 142: Which of the following is within the PACU nurse's independent scope of practice without a physician order?

Initiating a blood transfusion for anemia
Ordering a chest X-ray for suspected pneumothorax
Prescribing supplemental oxygen titration per ASPAN respiratory protocol (Correct answer)
Administering a PRN opioid analgesic per standing protocol

Correct answer: Prescribing supplemental oxygen titration per ASPAN respiratory protocol

Titrating supplemental oxygen to maintain target saturation per protocol is within PACU nursing scope without requiring a new physician order.

Question 143: Which intervention is most effective in preventing post-operative atelectasis in PACU patients?

Incentive spirometry and deep breathing exercises (Correct answer)
Aggressive intravenous fluid administration
Prophylactic antibiotic administration routinely
Complete bed rest and strict immobilization post-operatively

Correct answer: Incentive spirometry and deep breathing exercises

Incentive spirometry and deep breathing exercises promote alveolar expansion and are the most effective interventions for preventing post-operative atelectasis.

Question 144: Which of the following skills is essential for a CPAN when monitoring a patient after anesthesia?

Knowledge of pain management techniques (Correct answer)
Ability to perform anesthesia
Ability to conduct surgeries
Expertise in administering pre-anesthesia assessments

Correct answer: Knowledge of pain management techniques

Pain management is a cornerstone of post-anesthesia care, as patients frequently experience discomfort after surgery. A CPAN must possess comprehensive knowledge of various pharmacological and non-pharmacological pain relief techniques to effectively assess, intervene, and alleviate patient pain, promoting comfort and recovery.

Question 145: A PACU patient develops laryngospasm. After jaw thrust fails, what drug is the first-line pharmacologic intervention?

Ketamine 0.5 mg/kg IV
Vecuronium 0.1 mg/kg IV
Propofol 1 mg/kg IV
Succinylcholine 0.1–0.2 mg/kg IV (Correct answer)

Correct answer: Succinylcholine 0.1–0.2 mg/kg IV

A small 'laryngospasm dose' of succinylcholine (0.1–0.2 mg/kg IV) rapidly relaxes the spastic laryngeal muscles while minimizing full paralysis.

Question 146: What is the recommended position for a PACU patient at risk for aspiration?

Semi-prone or lateral decubitus position (Correct answer)
Supine with bed flat
Trendelenburg (head down)
High Fowler's with neck hyperextended

Correct answer: Semi-prone or lateral decubitus position

Lateral decubitus or semi-prone positioning helps protect the airway from aspiration by allowing secretions and vomitus to drain away from the glottis.

Question 147: A post-anesthesia patient's Steward Recovery Score is being calculated. Which three parameters does this scoring system evaluate?

Respiration, consciousness, and movement (Correct answer)
Blood pressure, oxygen saturation, and pain
Consciousness, color, and reflexes
Activity, breathing, and circulation

Correct answer: Respiration, consciousness, and movement

The Steward Recovery Score, used primarily in pediatric patients, evaluates respiration, consciousness, and movement to determine readiness for discharge from Phase I PACU.

Question 148: A patient with low health literacy needs to understand post-op activity restrictions. Which strategy is MOST effective?

Provide detailed written pamphlets with medical terminology
Ask the patient to research restrictions on a reputable website
Use plain language, short sentences, and pictures or diagrams (Correct answer)
Verbally explain restrictions using standard medical terms once

Correct answer: Use plain language, short sentences, and pictures or diagrams

Plain language with visual aids improves comprehension for patients with low health literacy and reduces post-discharge errors.

Question 149: A patient in the PACU develops inspiratory stridor. What is the most likely cause and priority intervention?

Post-operative hypotension requiring intravenous fluid bolus
Laryngospasm or airway obstruction requiring immediate airway repositioning and positive pressure ventilation if needed (Correct answer)
Post-operative nausea and vomiting requiring antiemetic administration
Allergic reaction to anesthesia requiring immediate antihistamine administration

Correct answer: Laryngospasm or airway obstruction requiring immediate airway repositioning and positive pressure ventilation if needed

Stridor in the PACU most likely indicates laryngospasm or partial airway obstruction requiring immediate airway management including repositioning and positive pressure ventilation.

Question 150: A nurse accidentally walks through a spilled body fluid on the PACU floor without protective footwear. The MOST appropriate immediate action is:

Clean the spill from the floor and notify housekeeping
Report to employee health for evaluation of exposure risk (Correct answer)
Wipe the shoes with an alcohol wipe and continue patient care
Remove shoes and wash feet with soap and water if skin contact occurred

Correct answer: Report to employee health for evaluation of exposure risk

Any potential body fluid exposure requires reporting to employee health for evaluation, documentation, and determination of follow-up needs per occupational safety guidelines.

Question 151: Which medication reverses opioid-induced respiratory depression in PACU patients?

Neostigmine
Sugammadex
Naloxone (Correct answer)
Flumazenil

Correct answer: Naloxone

Naloxone (Narcan) is the opioid antagonist used to reverse opioid-induced respiratory depression in the PACU.

Question 152: A post-thyroidectomy patient in the PACU develops inspiratory stridor and neck swelling 45 minutes after surgery. What is the most likely cause?

Residual neuromuscular blockade
Laryngospasm from irritating secretions
Hematoma compressing the trachea, requiring immediate surgical intervention (Correct answer)
Anaphylaxis to the surgical antiseptic

Correct answer: Hematoma compressing the trachea, requiring immediate surgical intervention

Neck hematoma after thyroidectomy can rapidly compress the trachea causing airway obstruction and is a surgical emergency requiring immediate wound opening at bedside.

Question 153: A PACU nurse administers a blood transfusion. Which documentation is REQUIRED at the START of the transfusion, separate from later monitoring entries?

The surgeon's preference for blood product type
The patient's insurance authorization number and blood bank cost
Pretransfusion vital signs, blood product verification (two-nurse check), blood type, unit number, and start time (Correct answer)
Only the completion time and patient's tolerance at the end

Correct answer: Pretransfusion vital signs, blood product verification (two-nurse check), blood type, unit number, and start time

Pre-transfusion documentation must capture the two-nurse verification process, product details, and baseline vital signs before the transfusion begins.

Question 154: A PACU patient who received general anesthesia with succinylcholine develops jaw rigidity, rapidly rising temperature, and muscle rigidity 30 minutes post-induction. Which lab value is the earliest indicator of the suspected complication?

Elevated serum potassium
Arterial blood gas showing metabolic acidosis
Elevated serum lactate (Correct answer)
Elevated creatine kinase (CK)

Correct answer: Elevated serum lactate

Elevated serum lactate from anaerobic metabolism is one of the earliest laboratory indicators of malignant hyperthermia, reflecting increased cellular oxygen consumption.

Question 155: During a PACU admission, a nurse identifies that antibiotic prophylaxis was NOT administered preoperatively per protocol. What is the MOST appropriate action?

Notify the surgeon and document the omission per facility policy (Correct answer)
Contact pharmacy to prepare the antibiotic for next-dose timing
Administer the antibiotic immediately in the PACU
Document the finding and continue routine monitoring

Correct answer: Notify the surgeon and document the omission per facility policy

The omission of prophylactic antibiotics is a reportable event; the surgeon must be notified to determine if post-incision administration is appropriate and the event documented per policy.

Question 156: Post-operative hypothermia in adult PACU patients is defined as a core temperature below which value?

35.0°C (95.0°F)
34.0°C (93.2°F)
36.0°C (96.8°F) (Correct answer)
37.0°C (98.6°F)

Correct answer: 36.0°C (96.8°F)

A core temperature below 36.0°C (96.8°F) is the clinical threshold for post-operative hypothermia in adult patients.

Question 157: Which laboratory value is MOST indicative of early sepsis in a PACU patient?

Serum creatinine of 1.0 mg/dL
Hemoglobin of 9.5 g/dL
Platelet count of 180,000/µL
Serum lactate greater than 2 mmol/L (Correct answer)

Correct answer: Serum lactate greater than 2 mmol/L

An elevated serum lactate (>2 mmol/L) indicates tissue hypoperfusion and is a key early biomarker of sepsis, triggering the Sepsis-3 protocol bundle.

Question 158: During a PACU fire emergency, which mnemonic guides the nurse's initial response sequence?

RACE (Rescue, Alarm, Contain, Extinguish) (Correct answer)
PASS (Pull, Aim, Squeeze, Sweep)
SBAR (Situation, Background, Assessment, Recommendation)
RICE (Rest, Ice, Compress, Elevate)

Correct answer: RACE (Rescue, Alarm, Contain, Extinguish)

The RACE mnemonic (Rescue, Alarm, Contain, Extinguish) provides the standardized fire response sequence in healthcare settings.

Question 159: A PACU nurse assesses a patient who suddenly develops unilateral arm weakness, facial droop, and slurred speech 40 minutes post-carotid endarterectomy. The priority action is:

Obtain a STAT CT head without contrast
Administer IV tPA per standing protocol
Immediately notify the surgeon and anesthesia provider (Correct answer)
Perform a complete neurological assessment using the NIH Stroke Scale

Correct answer: Immediately notify the surgeon and anesthesia provider

Post-carotid endarterectomy neurological deficits may require emergent return to the OR; immediate notification of the surgical team is the priority action.

Question 160: A PACU patient 1 hour after knee arthroplasty under spinal anesthesia has a blood pressure of 180/110 mmHg and complains of a throbbing headache. Which assessment question is most critical?

'When did you last take your antihypertensive medication?'
'On a scale of 0-10, how would you rate your headache?'
'Did you have high blood pressure before surgery?'
'Is the headache worse when you sit up or lie flat?' (Correct answer)

Correct answer: 'Is the headache worse when you sit up or lie flat?'

Post-dural puncture headache is positional (worse upright, relieved supine), and this distinction differentiates it from hypertensive headache, which has entirely different management.

Question 161: A PACU patient receiving a blood transfusion develops fever, chills, and back pain 30 minutes into the infusion. The nurse should FIRST:

Stop the transfusion and maintain IV access with normal saline (Correct answer)
Obtain a urine specimen to check for hemoglobinuria
Notify the blood bank and continue the transfusion at half speed
Slow the transfusion rate and administer acetaminophen

Correct answer: Stop the transfusion and maintain IV access with normal saline

Signs suggestive of a hemolytic transfusion reaction require immediate cessation of the transfusion while maintaining IV access to permit fluid resuscitation and medication administration.

Question 162: When assessing pain in a non-verbal intubated PACU patient, which behavioral indicator on the Critical Care Pain Observation Tool (CPOT) receives the highest score?

Patient tolerates ventilator with no coughing
Patient is relaxed with no muscle tension
Patient grimaces when repositioned
Patient fights the ventilator and coughs frequently (Correct answer)

Correct answer: Patient fights the ventilator and coughs frequently

Fighting the ventilator or coughing on the endotracheal tube scores 2 on the CPOT ventilator compliance subscale, indicating the highest level of distress in that domain.

Question 163: When caring for a patient with a regional nerve block in the PACU, the nurse's primary neurovascular assessment should include:

Deep tendon reflex testing at the patellar and Achilles tendons
Blood pressure comparison between bilateral extremities
Capillary refill, pulses, sensation, and motor function distal to the block (Correct answer)
Level of consciousness and pupillary response

Correct answer: Capillary refill, pulses, sensation, and motor function distal to the block

Neurovascular checks distal to a nerve block assess for vascular compromise or compartment syndrome by evaluating the 5 Ps: pain, pallor, pulselessness, paresthesia, and paralysis.

Question 164: A post-operative patient develops fever of 38.8°C, hypotension, and tachycardia six hours after surgery. These findings are MOST consistent with:

Malignant hyperthermia
Systemic inflammatory response syndrome (SIRS) (Correct answer)
Postoperative shivering
Neuroleptic malignant syndrome

Correct answer: Systemic inflammatory response syndrome (SIRS)

Fever, hypotension, and tachycardia meeting SIRS criteria postoperatively suggest possible sepsis requiring immediate evaluation and intervention.

Question 165: Which condition is characterized by muscle rigidity, rapidly rising hyperthermia, and autonomic instability following anesthetic exposure?

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

Correct answer: Malignant hyperthermia

Malignant hyperthermia presents with hypercapnia, muscle rigidity, rapidly rising temperature, and autonomic instability triggered by volatile anesthetics or succinylcholine.

Question 166: What is emergence delirium (emergence agitation) in the PACU?

A planned and expected component of the anesthesia recovery process
A sign indicating adequate intraoperative pain control was achieved
Normal sedation expected to follow all types of general anesthesia
An acute state of confusion, agitation, and disorientation occurring upon emergence from anesthesia (Correct answer)

Correct answer: An acute state of confusion, agitation, and disorientation occurring upon emergence from anesthesia

Emergence delirium is an acute neurological complication characterized by confusion, agitation, and disorientation that can occur during recovery from anesthesia.

Question 167: What does the term 'breakthrough pain' mean in PACU pain management?

Pain unrelated to the surgical procedure
Pain that occurs only during nighttime hours
Pain that exceeds the control of the current analgesic regimen (Correct answer)
Pain that occurs during a surgical procedure

Correct answer: Pain that exceeds the control of the current analgesic regimen

Breakthrough pain refers to episodes of acute pain that are not adequately controlled by the current analgesic regimen in place.

Question 168: A patient develops laryngospasm in the PACU immediately after extubation. The CPAN's first action should be:

Reinsert the endotracheal tube emergently
Administer succinylcholine 1 mg/kg IV immediately
Apply firm positive-pressure ventilation with 100% oxygen using a bag-valve-mask (Correct answer)
Place patient in lateral recovery position and observe

Correct answer: Apply firm positive-pressure ventilation with 100% oxygen using a bag-valve-mask

Firm positive-pressure ventilation with 100% oxygen is the initial treatment for laryngospasm, as pressure may break the spasm and restore ventilation.

Question 169: A PACU patient who is allergic to latex is scheduled to receive care. Which nursing action is MOST important for patient safety?

Administering prophylactic diphenhydramine before any procedure
Using only vinyl or nitrile gloves and ensuring a latex-free environment (Correct answer)
Keeping epinephrine at the bedside and proceeding with standard equipment
Placing an allergy bracelet on the patient and continuing routine care

Correct answer: Using only vinyl or nitrile gloves and ensuring a latex-free environment

Creating a latex-free environment — including latex-free gloves, IV tubing, and equipment — is the only effective prevention strategy for latex-allergic patients in the PACU.

Question 170: A patient in the PACU after abdominal surgery develops sudden, severe hypotension, tachycardia, and a rigid, distended abdomen. These findings suggest:

Tension pneumothorax from mechanical ventilation
Vasovagal response to pain
Acute hemorrhage or anastomotic leak requiring emergent notification (Correct answer)
Ileus from opioid administration

Correct answer: Acute hemorrhage or anastomotic leak requiring emergent notification

Sudden hemodynamic instability with abdominal rigidity after abdominal surgery signals a potentially catastrophic intra-abdominal complication requiring immediate surgical team notification.

Question 171: When performing a post-anesthesia neurological assessment, which finding indicates the highest level of consciousness on the AVPU scale?

Patient is alert and oriented (Correct answer)
Patient responds to painful stimuli
Patient responds to verbal stimulation
Patient is unresponsive

Correct answer: Patient is alert and oriented

On the AVPU scale, 'A' (Alert) represents the highest level, indicating the patient is fully conscious without any external stimulation.

Question 172: A patient is receiving ketorolac (Toradol) in the PACU. Which condition is a contraindication to its use?

Mild obesity
Peptic ulcer disease (Correct answer)
Type 2 diabetes
Mild hypertension

Correct answer: Peptic ulcer disease

Ketorolac is an NSAID that inhibits prostaglandins, increasing the risk of GI bleeding and ulceration, making active peptic ulcer disease a contraindication.

Question 173: What is malignant hyperthermia (MH) and why is it considered a critical PACU emergency?

A delayed allergic reaction to post-operative antibiotics
A mild post-operative fever treated with acetaminophen
A potentially fatal hypermetabolic reaction to certain anesthetic agents characterized by hyperthermia, muscle rigidity, and acidosis (Correct answer)
Normal temperature elevation expected after all general anesthesia cases

Correct answer: A potentially fatal hypermetabolic reaction to certain anesthetic agents characterized by hyperthermia, muscle rigidity, and acidosis

Malignant hyperthermia is a life-threatening pharmacogenetic disorder triggered by volatile anesthetics and succinylcholine, causing uncontrolled skeletal muscle metabolism.

Question 174: How many questions are on the CPAN certification examination?

200 questions
175 questions
