- Sharp pleuritic chest pain worsening with inspiration
- Chest pain relieved by sitting forward
- Tearing back pain with unequal blood pressures
- Chest pain radiating to the jaw with diaphoresis (Correct answer)
Correct answer: Chest pain radiating to the jaw with diaphoresis
ST elevation in inferior leads (II, III, aVF) with jaw radiation and diaphoresis is classic for inferior wall myocardial infarction requiring immediate intervention.
Question 14: A PACU nurse is evaluating a patient for discharge using the Post-Anesthetic Discharge Scoring System (PADSS). Which criterion must score at least 2 points for safe discharge?
- Patient must tolerate oral fluids without nausea
- Patient must have voided at least 200 mL of urine
- Vital signs within 20% of preoperative baseline (Correct answer)
- Pain must be rated 3/10 or less on the numeric scale
Correct answer: Vital signs within 20% of preoperative baseline
PADSS requires vital signs to be within 20% of preoperative baseline to score 2 points, reflecting hemodynamic stability for safe discharge.
Question 15: What is post-operative ileus and how does it present clinically?
- A post-operative complication that only occurs in pediatric patients after abdominal surgery
- An intestinal infection acquired during or after the surgical procedure
- 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)
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 16: During PACU assessment, a patient's capnography shows a waveform with a gradually rising plateau and a prolonged expiratory phase. This pattern is most consistent with:
- Obstructive airway disease such as bronchospasm (Correct answer)
- Hypoventilation from oversedation
- Normal ventilation
- Esophageal intubation
Correct answer: Obstructive airway disease such as bronchospasm
A shark-fin or oblique capnography waveform with prolonged expiration indicates obstructive airway disease due to impaired exhalation.
Question 17: Which laboratory value is MOST indicative of early sepsis in a PACU patient?
- Hemoglobin of 9.5 g/dL
- Serum lactate greater than 2 mmol/L (Correct answer)
- Serum creatinine of 1.0 mg/dL
- Platelet count of 180,000/µL
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 18: How can CPAN certification positively affect a nurse's career opportunities?

- Hypotension, concentrated urine, and decreased urine output
- Tachycardia, decreased skin turgor, dry mucous membranes
- Hypertension, crackles on auscultation, jugular venous distension (Correct answer)
- Tachycardia, flat neck veins, and poor capillary refill
Correct answer: Hypertension, crackles on auscultation, jugular venous distension
Hypertension, pulmonary crackles, and jugular venous distension are classic signs of fluid volume excess resulting from impaired cardiac or renal handling of fluid.
Question 33: Which intervention is most effective in preventing post-operative atelectasis in PACU patients?
- Incentive spirometry and deep breathing exercises (Correct answer)
- Complete bed rest and strict immobilization post-operatively
- Aggressive intravenous fluid administration
- Prophylactic antibiotic administration routinely
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 34: A patient in the PACU develops acute onset of severe dyspnea, pleuritic chest pain, and tachycardia after total hip arthroplasty. The nurse suspects pulmonary embolism. Which finding would further support this diagnosis?
- Elevated PaCO2 on ABG
- Metabolic alkalosis on ABG
- Decreased end-tidal CO2 (Correct answer)
- Bradycardia and hyperthermia
Correct answer: Decreased end-tidal CO2
Pulmonary embolism causes a ventilation-perfusion mismatch that decreases end-tidal CO2 due to increased dead space ventilation.
Question 35: Post-dural puncture headache (PDPH) following spinal anesthesia is best characterized by:
- Occipital headache that is worse when supine and relieved when upright
- Diffuse headache unrelated to position, associated with fever
- Bifrontal or occipital headache that worsens with upright position and improves when supine (Correct answer)
- Unilateral throbbing headache with photophobia and nausea
Correct answer: Bifrontal or occipital headache that worsens with upright position and improves when supine
PDPH is a positional headache caused by CSF leakage through the dural puncture site; it worsens when upright and improves when lying flat.
Question 36: How should a PACU nurse objectively assess for post-operative hypothermia?
- Ask the patient whether they feel cold and accept their answer
- Rely solely on the patient's subjective complaint of feeling cold
- Monitor core temperature with a reliable thermometer and assess for shivering and vital sign changes (Correct answer)
- Rely on visual inspection of skin color as the primary assessment method
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 37: A nurse applying for CPAN certification must submit proof of RN licensure in which country or countries?
- United States or Canada (Correct answer)

- Supratherapeutic aPTT greater than 120 seconds (Correct answer)
- Thrombocytopenia with a platelet count below 100,000/μL
- Elevated fibrinogen levels
Correct answer: Supratherapeutic aPTT greater than 120 seconds
Bleeding with heparin therapy most commonly results from a supratherapeutic aPTT; values >120 seconds significantly increase hemorrhagic risk and warrant dose adjustment or reversal with protamine.
Question 39: A PACU nurse receives a verbal order by telephone for a medication. According to documentation standards, what is the CORRECT approach?
- Ask a colleague to listen and co-sign as the primary order-giver
- Refuse all telephone orders and require written orders only
- Write the order, read it back to the physician for confirmation, administer, and document as a verbal/telephone order with the physician's name (Correct answer)
- Administer the medication and document it as the nurse's own clinical decision
Correct answer: Write the order, read it back to the physician for confirmation, administer, and document as a verbal/telephone order with the physician's name
The read-back verification process for telephone orders reduces errors, and proper documentation includes the prescriber's name, time, and order details.
Question 40: What is the most serious adverse effect to monitor when administering opioids in the PACU?
- Respiratory depression (Correct answer)
- Urinary retention
- Constipation
- Nausea and vomiting
Correct answer: Respiratory depression
Respiratory depression is the most serious and potentially life-threatening side effect of opioid administration in the PACU.

- Obtain consent since the patient is in their care
- Have the patient sign consent upon discharge to Phase II
- Ensure the ordering provider obtains consent; the nurse's role is to witness the signature (Correct answer)
- Consent is not needed for post-operative procedures
Correct answer: Ensure the ordering provider obtains consent; the nurse's role is to witness the signature
Informed consent must be obtained by the proceduralist; the nurse may witness the signature but is not responsible for the informed consent discussion.
Question 47: A PACU patient who underwent oral surgery develops progressive swelling of the tongue and uvula with increasing respiratory difficulty. What condition should the nurse suspect?
- Normal post-operative swelling
- Angioedema or airway edema requiring urgent airway management (Correct answer)
- Post-operative nausea and vomiting
- Opioid-induced sedation
Correct answer: Angioedema or airway edema requiring urgent airway management
Progressive tongue and uvular swelling with respiratory difficulty after oral or head/neck surgery suggests angioedema or surgical edema requiring immediate airway intervention.
Question 48: A 55-year-old male in the PACU after prostatectomy has an indwelling urinary catheter with output of 250 mL/hr of clear yellow urine. His blood pressure is 155/95 mmHg and heart rate is 88 bpm. Which assessment is most important to perform next?
- Assess for bladder distension above the catheter
- Evaluate serum sodium level for hyponatremia (Correct answer)
- Measure abdominal girth for internal bleeding
- Check for signs of fluid overload including lung auscultation
Correct answer: Evaluate serum sodium level for hyponatremia
High urine output after prostate surgery with hypertension may indicate absorption of hypotonic irrigating fluid causing TURP syndrome with dilutional hyponatremia.
Question 49: Which collaborative responsibility does the PACU nurse share with the surgical team regarding wound management?
- Independently deciding when to change a surgical dressing
- Assessing and documenting dressing status and reporting abnormal drainage (Correct answer)
- Performing wound closure if sutures are loose

Question 55: Which medication reverses opioid-induced respiratory depression in PACU patients?
- Naloxone (Correct answer)
- Sugammadex
- Neostigmine
- Flumazenil
Correct answer: Naloxone
Naloxone (Narcan) is the opioid antagonist used to reverse opioid-induced respiratory depression in the PACU.
Question 56: A PACU patient receiving a blood transfusion develops fever, chills, and back pain 30 minutes into the infusion. The nurse should FIRST:
- Notify the blood bank and continue the transfusion at half speed
- Slow the transfusion rate and administer acetaminophen
- Stop the transfusion and maintain IV access with normal saline (Correct answer)
- Obtain a urine specimen to check for hemoglobinuria
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 57: A PACU nurse notes a discrepancy between the intraoperative medication record and the anesthesia provider's verbal report. What is the appropriate action?
- Contact the charge nurse to resolve the discrepancy
- Document both versions and address it later
- Proceed with care based on the verbal report only
- Clarify the discrepancy with the anesthesia provider before accepting the patient (Correct answer)
Correct answer: Clarify the discrepancy with the anesthesia provider before accepting the patient
Medication discrepancies must be clarified before accepting patient responsibility to ensure safe, accurate post-anesthesia care.
Question 58: When should the PACU nurse most urgently prepare for reintubation?
- Patient reports mild nausea
- Patient requests to remove the nasal cannula
- Respiratory rate is 18 breaths/minute
- Patient develops progressive stridor unresponsive to jaw thrust and supplemental oxygen (Correct answer)
Correct answer: Patient develops progressive stridor unresponsive to jaw thrust and supplemental oxygen
Progressive stridor unresponsive to initial airway maneuvers signals impending complete airway obstruction and requires immediate preparation for reintubation.
Question 59: When is it appropriate to modify a standard clinical procedure?
- When patient-specific factors require adaptation based on clinical judgment (Correct answer)
- Whenever it saves time
- Never, procedures must always be identical
- Only when insurance requires changes
Correct answer: When patient-specific factors require adaptation based on clinical judgment
Clinical procedures may need modification based on individual patient factors, but changes should be guided by clinical judgment and documented.
Question 60: What critical thinking skill is most important for a Certified Post Anesthesia Nurse when dealing with a rapidly changing patient condition?
- Ability to educate the family about anesthesia
- Ability to delegate tasks to others
- Ability to recognize and act on signs of complications quickly (Correct answer)
- Ability to calculate medication dosages
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 61: A patient's family member insists on staying at the bedside and interrupts the nurse's assessment. The BEST action is to:
- Ask security to remove the family member immediately
- Allow the family member to stay and conduct the assessment as best you can
- Acknowledge the family member's concern, briefly explain what you need to do, and request a few minutes with the patient (Correct answer)
- Postpone the assessment until the family member leaves voluntarily
Correct answer: Acknowledge the family member's concern, briefly explain what you need to do, and request a few minutes with the patient
Acknowledging family concern and politely requesting brief privacy balances patient safety, family support, and professional assessment needs.
Question 62: What is a drug contraindication?
- A drug interaction that enhances effectiveness
- A condition that makes a particular treatment inadvisable (Correct answer)
- A type of allergic reaction
- A reason to increase the dosage
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 63: What is the first-line specific treatment for malignant hyperthermia?
- Dantrolene sodium administration combined with aggressive cooling and supportive care (Correct answer)
- Cooling blankets and ice packs alone without any medication
- Administering additional anesthesia to stop skeletal muscle activity
- Halting the procedure and observation only without pharmacologic treatment
Correct answer: Dantrolene sodium administration combined with aggressive cooling and supportive care
Dantrolene sodium is the specific antidote for malignant hyperthermia and must be given promptly along with aggressive cooling and supportive treatment.
Question 64: Which pharmacologic property determines how quickly an inhalational anesthetic is taken up and eliminated from the body?
- Minimum alveolar concentration (MAC)
- Vapor pressure
- Molecular weight
- Blood/gas partition coefficient (Correct answer)
Correct answer: Blood/gas partition coefficient
A low blood/gas partition coefficient means the agent is poorly soluble in blood, leading to rapid equilibration and faster onset and offset of anesthesia.
Question 65: Why is it important to check for drug allergies before administration?
- To determine the correct billing code
- To complete insurance paperwork
- To prevent potentially life-threatening allergic reactions (Correct answer)
- To satisfy pharmacy inventory requirements
Correct answer: To prevent potentially life-threatening allergic reactions
Checking allergies prevents serious reactions including anaphylaxis, which can be fatal if not identified beforehand.
Question 66: A culturally competent PACU nurse caring for a patient whose family insists on being present for all assessments should:
- Consider the request within privacy and safety parameters and negotiate a culturally sensitive solution (Correct answer)
- Deny the request to maintain clinical efficiency
- Allow unlimited family presence regardless of clinical circumstances
- Ask the patient only after the family has left the room
Correct answer: Consider the request within privacy and safety parameters and negotiate a culturally sensitive solution
Cultural competence requires negotiating culturally sensitive care within safety and privacy constraints, balancing family inclusion with clinical needs.
Question 67: A PACU nurse is preparing to administer ketorolac 30 mg IV for pain management. Which patient condition is a contraindication to this medication?
- History of mild asthma controlled with PRN albuterol
- Age of 55 years with no comorbidities
- Estimated GFR of 25 mL/min/1.73m² (Correct answer)
- Allergy to sulfa-based antibiotics
Correct answer: Estimated GFR of 25 mL/min/1.73m²
Ketorolac is contraindicated in renal impairment (GFR <30 mL/min/1.73m²) because NSAIDs can further reduce renal perfusion and precipitate acute kidney injury.
Question 68: When renewing CPAN certification, a nurse who prefers not to submit continuing education hours may instead choose to:
- Submit a portfolio of clinical cases
- Obtain supervisor verification of competency
- Retake and pass the CPAN examination (Correct answer)

Renewal by re-examination is an accepted alternative to the CE route; passing the current version of the exam satisfies the renewal requirement.
Question 69: A patient in Phase II PACU following laparoscopic surgery complains of right shoulder pain rated 7/10 despite adequate incisional analgesia. This finding is best explained by:
- Musculoskeletal strain from patient movement during recovery
- Referred pain from residual diaphragmatic irritation by CO2 (Correct answer)
- Brachial plexus injury from intraoperative positioning
- Inadequate systemic analgesia requiring opioid titration
Correct answer: Referred pain from residual diaphragmatic irritation by CO2
Residual CO2 used for pneumoperitoneum irritates the diaphragm, causing referred pain to the ipsilateral shoulder via the phrenic nerve.
Question 70: 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
- Acetaminophen toxicity
- Opioid overdose
- Local anesthetic systemic toxicity (LAST) (Correct answer)
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 71: What should be done first when a needlestick injury occurs?
- Complete an incident report before any other action
- Apply a bandage without washing
- Continue working and report at end of shift
- Wash the affected area immediately with soap and water (Correct answer)
Correct answer: Wash the affected area immediately with soap and water
Immediate washing with soap and water helps reduce the risk of infection transmission after a needlestick injury.
Question 72: A patient recovering from ambulatory surgery asks to be discharged. The nurse notes the patient cannot stand without dizziness. Using the PADSS criteria, this patient should receive a score of:
- 1 for the ambulation criterion (Correct answer)
- 0 for the ambulation criterion
- The PADSS tool does not assess ambulation
- 2 for the ambulation criterion
Correct answer: 1 for the ambulation criterion
The Post-Anesthetic Discharge Scoring System (PADSS) scores ambulation as 1 when the patient has dizziness/giddiness but is able to ambulate with assistance.
Question 73: A patient is transferred from PACU to a surgical floor. Which document MUST accompany the patient to ensure continuity of care?
- A PACU nursing handoff report including vital signs, medications given, and current status (Correct answer)

- At the time of transfer to Phase II recovery
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 75: What is the primary pain assessment tool recommended for use in post-anesthesia care units (PACUs)?
- Ramsay Sedation Scale
- Glasgow Coma Scale
- Braden Scale
- Numeric Rating Scale (NRS) (Correct answer)
Correct answer: Numeric Rating Scale (NRS)
The Numeric Rating Scale (NRS) is widely used in PACUs as it allows patients to rate pain intensity from 0 to 10.
Question 76: What does the term 'breakthrough pain' mean in PACU pain management?
- Pain that exceeds the control of the current analgesic regimen (Correct answer)
- Pain that occurs during a surgical procedure
- Pain that occurs only during nighttime hours
- Pain unrelated to the 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 77: A pediatric patient in the PACU following adenotonsillectomy develops SpO2 of 88%, retractions, and a high-pitched inspiratory sound. After airway repositioning fails, the next intervention is:
- Administer racemic epinephrine via nebulizer
- Apply 100% O2 via blow-by
- Administer CPAP via facemask with 5–10 cmH2O (Correct answer)
- Perform immediate re-intubation
Correct answer: Administer CPAP via facemask with 5–10 cmH2O
CPAP via facemask splints the airway open and recruits alveoli, making it the preferred initial intervention for post-extubation airway obstruction unresponsive to repositioning.
Question 78: Warm intravenous fluid administration in the PACU primarily prevents which type of heat loss?
- Radiation
- Conduction from cold fluids lowering core temperature (Correct answer)
- Convection
- Evaporation
Correct answer: Conduction from cold fluids lowering core temperature
Administering cold IV fluids directly lowers core temperature via conduction; warming fluids to body temperature prevents this internal heat drain.
Question 79: When documenting the use of physical restraints in the PACU, which element is REQUIRED by Joint Commission standards?

- The family's verbal agreement overheard in the waiting room
- Only the physician's order without nursing assessment
- The clinical justification, type of restraint, time applied, neurovascular checks, and patient response (Correct answer)
Correct answer: The clinical justification, type of restraint, time applied, neurovascular checks, and patient response
Joint Commission requires documentation of clinical justification, restraint type, application time, ongoing monitoring, and patient response for all restraint use.
Question 80: Which temperature monitoring site provides the most accurate reflection of core body temperature in PACU patients?
- Pulmonary artery (PA catheter) (Correct answer)
- Oral
- Axillary
- Temporal artery
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 81: A Phase II PACU patient is being prepared for home discharge after outpatient laparoscopic surgery. Which discharge instruction is MOST critical for patient safety?
- Avoid strenuous exercise for 6 weeks
- Resume a full diet immediately upon arriving home
- Do not drive or operate machinery for 24 hours after anesthesia (Correct answer)
- Return to work the next business day
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 82: A PACU nurse notes that a patient has an end-tidal CO2 (EtCO2) waveform that is gradually rising. What does this finding indicate?
- Oxygen toxicity
- Hypoventilation with CO2 retention (Correct answer)
- Improving ventilation and adequate CO2 elimination
- Normal variation with no clinical significance
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 83: A post-thyroidectomy patient in the PACU develops inspiratory stridor, dysphagia, and neck swelling. The nurse's immediate priority is:
- Apply an ice collar to reduce swelling
- Administer calcium gluconate 1 g IV
- Elevate the head of bed and administer supplemental oxygen
- Prepare for emergency airway management and alert the surgeon (Correct answer)
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 84: Which of the following is a mandatory requirement to become eligible for the CPAN certification exam?

Question 86: 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
- Fluid overload causing pulmonary edema
- Residual neuromuscular blockade causing inadequate respiratory effort (Correct answer)
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 87: Which medication class is commonly used as an adjunct to opioids for post-operative pain management in the PACU?
- Antihistamines
- Antihypertensives
- Antiemetics
- NSAIDs (non-steroidal anti-inflammatory drugs) (Correct answer)
Correct answer: NSAIDs (non-steroidal anti-inflammatory drugs)
NSAIDs reduce inflammation and provide analgesia, allowing for reduced opioid doses and fewer opioid-related side effects.
Question 88: What is malignant hyperthermia (MH) and why is it considered a critical PACU emergency?
- A potentially fatal hypermetabolic reaction to certain anesthetic agents characterized by hyperthermia, muscle rigidity, and acidosis (Correct answer)
- A delayed allergic reaction to post-operative antibiotics
- A mild post-operative fever treated with acetaminophen
- 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 89: A PACU patient who received spinal anesthesia for lower extremity surgery develops sudden hypotension, bradycardia, and nausea 45 minutes post-procedure. The spinal block level is assessed at T2. This complication is called:
- Total spinal anesthesia
- High spinal with sympathectomy (Correct answer)
- Autonomic dysreflexia
- Vasovagal syncope
Correct answer: High spinal with sympathectomy
A high spinal block at T2 causes extensive sympathetic blockade resulting in hypotension, bradycardia, and nausea due to loss of cardiac accelerator fibers.
Question 90: From a risk management perspective, accreditation helps PACUs by:
- Identifying gaps in practice before adverse events occur (Correct answer)
- Reducing the need for internal incident reporting
- Transferring malpractice risk to the accrediting body
- Eliminating all liability for clinical errors
Correct answer: Identifying gaps in practice before adverse events occur
The accreditation process proactively identifies systems and practice gaps, enabling correction before they lead to patient harm.
Question 91: A patient in the PACU receives neostigmine to reverse neuromuscular blockade. Which drug must be given concurrently to prevent bradycardia?
- Dopamine
- Phenylephrine
- Epinephrine
- Atropine (Correct answer)
Correct answer: Atropine
Neostigmine inhibits acetylcholinesterase and increases muscarinic activity, requiring concurrent anticholinergic agents like atropine or glycopyrrolate to prevent bradycardia.
Question 92: A patient develops hypotension 30 minutes after surgery. What is the PACU nurse's priority action?
- Document the finding and wait for spontaneous resolution
- Assess for the underlying cause, notify the physician, and initiate appropriate interventions based on findings (Correct answer)
- Immediately administer vasopressors without physician notification
- 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 93: Why is post-operative nausea and vomiting (PONV) a significant concern in the PACU?
- It is a reliable sign that anesthesia was administered successfully
- It is a minor inconvenience with no serious clinical significance
- It can cause aspiration, wound dehiscence, increased intracranial pressure, and significant patient distress (Correct answer)
- It is a condition that only affects pediatric surgical patients
Correct answer: It can cause aspiration, wound dehiscence, increased intracranial pressure, and significant patient distress
PONV is a common post-operative complication that can lead to aspiration, wound dehiscence, elevated intracranial pressure, and significant patient discomfort.
Question 94: Dantrolene is the treatment for malignant hyperthermia. What is its mechanism of action?
- Inhibits calcium release from the sarcoplasmic reticulum via RYR1 receptor (Correct answer)
- Promotes potassium reuptake in skeletal muscle
- Inhibits acetylcholine release at the neuromuscular junction
- Blocks calcium channels in cardiac muscle
Correct answer: Inhibits calcium release from the sarcoplasmic reticulum via RYR1 receptor
Dantrolene binds the ryanodine receptor (RYR1) on the sarcoplasmic reticulum, blocking the uncontrolled calcium release that drives the hypermetabolic state of MH.
Question 95: What is the purpose of transmission-based precautions?
- To replace standard precautions entirely
- To provide additional protection for patients with specific infections (Correct answer)
- To simplify the care process
- To reduce supply costs
Correct answer: To provide additional protection for patients with specific infections

- Elevate the head of the bed 30 degrees
- Administer phenylephrine 100 mcg IV push
Correct answer: Administer an IV fluid bolus of 500 mL normal saline
Hypovolemic hypotension in the PACU is first treated with IV fluid resuscitation to restore intravascular volume before vasopressors are considered.
Question 97: A PACU nurse assesses a patient post-cardiac surgery and notes the mediastinal chest tube has suddenly stopped draining after outputting 300 mL/hr for 2 hours. The nurse should first:
- Clamp the chest tube and notify the surgeon
- Increase suction on the drainage system
- Document the finding as a positive sign of decreased bleeding
- Assess for tube kinking and signs of cardiac tamponade (Correct answer)
Correct answer: Assess for tube kinking and signs of cardiac tamponade
Abrupt cessation of mediastinal drainage after high output may indicate clot obstruction and impending tamponade; immediate assessment for tube kinking and tamponade signs is essential.
Question 98: What clinical signs of a pulmonary embolism (PE) should a PACU nurse be prepared to recognize?
- Hypertension and bradycardia with normal oxygen saturation throughout
- Sudden onset dyspnea, pleuritic chest pain, tachycardia, and decreased oxygen saturation (Correct answer)
- Isolated fever without any associated respiratory or hemodynamic changes
- Gradual blood pressure decrease developing over several hours post-operatively
Correct answer: Sudden onset dyspnea, pleuritic chest pain, tachycardia, and decreased oxygen saturation
Pulmonary embolism classically presents with sudden dyspnea, pleuritic chest pain, tachycardia, and hypoxia, requiring immediate emergency response.
Question 99: Unexplained hyperthermia in the PACU should prompt the nurse to first assess for which condition?
- Hyperglycemia
- Hypertension
- Malignant hyperthermia or infection (Correct answer)
- Dehydration
Correct answer: Malignant hyperthermia or infection
Unexplained fever in the PACU must urgently rule out malignant hyperthermia or an infectious source, as both require immediate intervention.
Question 100: A patient emerges from general anesthesia with significant laryngospasm. What is the most appropriate initial intervention?
- Apply firm upward jaw thrust and administer 100% oxygen via positive pressure ventilation (Correct answer)
- Perform emergency tracheostomy
- Administer IV atropine immediately
- Place patient in Trendelenburg position and wait
Correct answer: Apply firm upward jaw thrust and administer 100% oxygen via positive pressure ventilation
Jaw thrust and 100% oxygen with positive-pressure ventilation are the initial treatment for laryngospasm, which is involuntary spasm of the vocal cords.
Question 101: During assessment of a patient after thyroid surgery, the PACU nurse notices inspiratory stridor and the patient clutches their throat. The priority intervention after calling for help is:
- Apply CPAP at 10 cmH2O
- Prepare for emergent reintubation
- Open the surgical wound to relieve tracheal compression (Correct answer)

Question 114: A post-anesthesia patient's Steward Recovery Score is being calculated. Which three parameters does this scoring system evaluate?
- Consciousness, color, and reflexes
- Respiration, consciousness, and movement (Correct answer)
- Activity, breathing, and circulation
- Blood pressure, oxygen saturation, and pain
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 115: 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 creatine kinase (CK)
- Arterial blood gas showing metabolic acidosis
- Elevated serum potassium
- Elevated serum lactate (Correct answer)
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 116: 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 117: A post-anesthesia nurse is floated to a unit where they have no PACU experience. The safest and most ethical action is to:
- Accept only if a buddy nurse is available
- Accept the assignment and learn as situations arise
- Communicate concerns about competency to the charge nurse and request orientation or an appropriate assignment (Correct answer)
- Refuse the assignment entirely and leave the hospital
Correct answer: Communicate concerns about competency to the charge nurse and request orientation or an appropriate assignment
Nurses have an ethical and professional responsibility to practice only within their competency; communicating limitations while seeking support or reassignment protects patient safety.
Question 118: Which factors should guide the PACU nurse's choice of pain management approach?

Pain management must be individualized based on multiple factors including procedure type, medical history, allergies, and current pain assessment data.
Question 119: What is emergence delirium (emergence agitation) in the PACU?
- 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)
- A sign indicating adequate intraoperative pain control was achieved
- A planned and expected component of the anesthesia recovery process
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 120: Forced-air warming blankets achieve warming primarily through which mechanism?
- Evaporation of heated moisture
- Radiation from infrared elements
- Conduction via heated surface contact
- Convection via warm air flow over skin (Correct answer)
Correct answer: Convection via warm air flow over skin
Forced-air warming blankets warm the patient through convection, circulating warm air across a large skin surface area.
Question 121: A PACU patient reports a pain score of 8/10 after receiving opioids. What should the nurse assess first?
- Administer additional opioids immediately
- Respiratory rate and oxygen saturation (Correct answer)
- Apply ice packs to the surgical site
- Ask the patient to wait 30 minutes
Correct answer: Respiratory rate and oxygen saturation
Before administering additional analgesics, the PACU nurse must first assess respiratory status to ensure it is safe to give more opioids.
Question 122: During an unannounced accreditation survey, a surveyor asks a PACU nurse about the unit's malignant hyperthermia protocol. This question BEST assesses:
- The nurse's ability to delegate emergency responses to physicians
- The efficiency of the unit's supply chain management
- Administrative budget allocation for emergency supplies

- Morphine
- Meperidine
- Hydromorphone
- Fentanyl (Correct answer)
Correct answer: Fentanyl
Fentanyl is metabolized to inactive compounds and does not accumulate in renal failure, unlike morphine (morphine-6-glucuronide) or meperidine (normeperidine).
Question 127: Which of the following is a communication skill that is vital for a CPAN when working with patients?
- Explaining surgical procedures in detail
- Writing patient discharge reports
- Giving anesthesia recommendations to doctors
- Effectively managing patient expectations and concerns during recovery (Correct answer)
Correct answer: Effectively managing patient expectations and concerns during recovery
Patients emerging from anesthesia are often disoriented, anxious, or in pain, making clear and empathetic communication essential. A CPAN must effectively explain what to expect, address patient and family concerns, and provide reassurance to promote a sense of safety and comfort during the recovery process.
Question 128: When a PACU patient becomes hostile and verbally abusive, the nurse's ethical obligation is to:
- Discharge the patient immediately for staff safety
- Continue to provide safe, professional care while setting clear behavioral limits (Correct answer)
- Administer sedation without an order to manage the behavior
- Refuse to provide care until the patient calms down
Correct answer: Continue to provide safe, professional care while setting clear behavioral limits
Nurses must provide care without abandonment while also setting appropriate professional limits on abusive behavior, balancing patient care with a safe work environment.
Question 129: 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?

- 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 130: A nurse documents 'patient appears comfortable' without recording a numerical pain score. Which legal principle does this documentation MOST violate?
- The principle of patient autonomy
- The principle of beneficence in nursing ethics
- The standard of care requiring objective, measurable pain assessment documentation (Correct answer)
- The HIPAA privacy rule
Correct answer: The standard of care requiring objective, measurable pain assessment documentation
Professional standards require objective, measurable documentation using validated pain scales rather than subjective nurse interpretations.
Question 131: What is the underlying cause of post-operative shivering and how should a PACU nurse manage it?
- A thermoregulatory response to hypothermia managed with warming blankets and warm IV fluids (Correct answer)
- A completely normal finding requiring no assessment or intervention
- A sign of infection requiring immediate antibiotic administration
- A sign of anesthetic overdose requiring emergency reversal agents
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.

Correct answer: Malignant hyperthermia
Malignant hyperthermia presents with hypercapnia, muscle rigidity, rapidly rising temperature, and autonomic instability triggered by volatile anesthetics or succinylcholine.
Question 164: A PACU patient with a history of obstructive sleep apnea (OSA) requires opioids for pain. What special precaution should be taken?
- Increase monitoring frequency and keep supplemental oxygen readily available (Correct answer)
- Avoid all pain medication and use only positioning
- Administer maximum allowable opioid doses to prevent under-treatment
- Discharge immediately to minimize opioid exposure time
Correct answer: Increase monitoring frequency and keep supplemental oxygen readily available
Patients with OSA are at higher risk for opioid-induced respiratory depression and require more frequent monitoring along with readily available supplemental oxygen.
Question 165: What is post-operative cognitive dysfunction (POCD) and which patient population is at greatest risk?
- 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
- A planned sedation effect that affects all age groups equally
- A cognitive condition that exclusively affects pediatric surgical patients
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 166: During a fire in the PACU, the nurse should use the RACE acronym. What is the correct order of actions?
- Respond, Activate sprinklers, Contain patients, Evacuate
- Rescue, Alarm, Confine, Extinguish/Evacuate (Correct answer)
- Rescue, Alert staff, Close doors, Exit the building
- Report, Alarm, Confine, Evacuate
Correct answer: Rescue, Alarm, Confine, Extinguish/Evacuate
RACE stands for Rescue (remove patients from immediate danger), Alarm (activate fire alarm), Confine (close doors to contain fire), and Extinguish/Evacuate, in that order.
