Question 20: 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)
- Blocks calcium channels in cardiac muscle
- Inhibits acetylcholine release at the neuromuscular junction
- Promotes potassium reuptake in skeletal 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 21: A surgeon calls the PACU and gives a verbal order for a medication that seems unusually high dose. The PACU nurse should:
- Refuse to give the medication and document the refusal
- Clarify the order with the surgeon and verify against references before administration (Correct answer)
- Administer the medication as ordered since the surgeon is responsible
- Ask another nurse to administer it to avoid liability
Correct answer: Clarify the order with the surgeon and verify against references before administration
The nurse is professionally and legally responsible for any medication administered and must verify questionable orders before proceeding.
Question 22: Which patient population is at highest risk for developing post-operative hypothermia in the PACU?
- Healthy adults aged 18–40
- Pediatric and elderly patients (Correct answer)
- Patients undergoing laparoscopic procedures

Correct answer: Contact precautions
MRSA wound infections require contact precautions — gown and gloves — in addition to standard precautions to prevent transmission through direct or indirect contact.
Question 35: Which intervention is most effective in preventing post-operative respiratory complications in Phase I PACU patients?
- Administering prophylactic bronchodilators to all post-operative patients
- Encouraging deep breathing exercises, coughing, and early semi-upright positioning (Correct answer)
- Maintaining the patient in a supine flat position to maximize comfort
- Restricting IV fluids to avoid pulmonary edema
Correct answer: Encouraging deep breathing exercises, coughing, and early semi-upright positioning
Deep breathing, coughing, and semi-upright positioning promote lung expansion and secretion clearance, reducing atelectasis and pneumonia risk post-operatively.
Question 36: Ketamine is commonly used for procedural sedation. Which unique hemodynamic property makes it useful in trauma patients with hemorrhagic shock?
- Stimulates catecholamine release, maintaining or increasing blood pressure (Correct answer)
- Blocks mu-opioid receptors
- Decreases myocardial oxygen demand
- Causes peripheral vasodilation
Correct answer: Stimulates catecholamine release, maintaining or increasing blood pressure
Ketamine stimulates sympathetic nervous system activity, causing catecholamine release that maintains or elevates blood pressure, heart rate, and cardiac output.
Question 37: When a PACU patient becomes hostile and verbally abusive, the nurse's ethical obligation is to:
- Refuse to provide care until the patient calms down
- Discharge the patient immediately for staff safety
- Administer sedation without an order to manage the behavior
- Continue to provide safe, professional care while setting clear behavioral limits (Correct answer)
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 38: What should be done first when a needlestick injury occurs?
- Apply a bandage without washing
- Continue working and report at end of shift
- Complete an incident report before any other action

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 39: A PACU patient with a history of obstructive sleep apnea (OSA) requires opioids for pain. What special precaution should be taken?
- Avoid all pain medication and use only positioning
- Administer maximum allowable opioid doses to prevent under-treatment
- Discharge immediately to minimize opioid exposure time
- Increase monitoring frequency and keep supplemental oxygen readily available (Correct answer)
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 40: A patient with a history of obstructive sleep apnea (OSA) is in the PACU after laparoscopic cholecystectomy. Which assessment finding warrants the highest concern?
- Pain score of 6/10 requiring opioid analgesic
- Heart rate of 88 bpm and blood pressure 145/90 mmHg
- Loud snoring with SpO2 dropping to 86% during sleep (Correct answer)
- SpO2 of 94% on 2L/min nasal cannula while awake
Correct answer: Loud snoring with SpO2 dropping to 86% during sleep
OSA patients are at highest risk for airway obstruction during sleep; SpO2 dropping to 86% during snoring indicates significant upper airway obstruction requiring intervention.
Question 41: Which element is MOST critical to include when documenting a patient's consent for a procedure in the PACU?
- The nurse's assessment of patient competency at time of consent
- Confirmation that consent was obtained preoperatively by the surgeon (Correct answer)
- The specific risks and benefits discussed with the patient
- The family member who witnessed the consent process
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 42: 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 43: How should a PACU nurse document pain assessments to ensure continuity of care?
- Once per shift regardless of any interventions performed
- Before and after every pain intervention, including time, score, and patient response (Correct answer)
- Only when pain score is above 5 out of 10
- Only if the patient specifically requests that pain be documented
Correct answer: Before and after every pain intervention, including time, score, and patient response
Accurate pain documentation includes pre- and post-intervention pain scores, timing, and patient response to ensure safe continuity of care.
Question 44: How should a PACU nurse objectively assess for post-operative hypothermia?
- Rely solely on the patient's subjective complaint of feeling cold
- 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)
- 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 45: 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
- 60 minutes after administration
- 15–30 minutes or at peak effect of the medication (Correct answer)
- Only when the patient requests reassessment
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 46: What is a regional nerve block in the context of PACU pain management?
- General anesthesia administered after surgery for continued sedation
- Local anesthetic injected near specific nerves to block pain in a defined area (Correct answer)
- Systemic opioid administration via intravenous route

- Inhaled short-acting beta-2 agonist (e.g., albuterol) (Correct answer)
- IV aminophylline
- IV methylprednisolone
- Subcutaneous epinephrine only
Correct answer: Inhaled short-acting beta-2 agonist (e.g., albuterol)
Inhaled short-acting beta-2 agonists such as albuterol are the first-line treatment for bronchospasm, providing rapid bronchodilation with minimal systemic effects.
Question 48: A patient emerges from general anesthesia with significant laryngospasm. What is the most appropriate initial intervention?
- Perform emergency tracheostomy
- Place patient in Trendelenburg position and wait
- Apply firm upward jaw thrust and administer 100% oxygen via positive pressure ventilation (Correct answer)
- Administer IV atropine immediately
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 49: The modified Aldrete scoring system used in PACU Phase I recovery evaluates which five parameters?
- Orientation, motor function, vital signs, pain, and ambulation
- Activity, respiration, circulation, consciousness, and oxygen saturation (Correct answer)
- Level of consciousness, airway, breathing, circulation, and skin color
- Pain, sedation, nausea, bleeding, and temperature
Correct answer: Activity, respiration, circulation, consciousness, and oxygen saturation
The modified Aldrete score assesses activity, respiration, circulation, consciousness, and oxygen saturation to determine readiness for Phase II or discharge.
Question 50: Which non-pharmacologic intervention is appropriate for mild to moderate pain in the PACU?
- Patient positioning and cold therapy (Correct answer)
- Ketamine infusion
- Epidural analgesia
- Intravenous fentanyl
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 51: What is multimodal analgesia in the post-anesthesia setting?
- Administering the maximum dose of a single analgesic
- Using only non-pharmacologic methods
- Combining different analgesic medications targeting different pain pathways (Correct answer)
- Using only IV opioids for pain control
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 52: A post-anesthesia patient's Steward Recovery Score is being calculated. Which three parameters does this scoring system evaluate?
- Activity, breathing, and circulation
- Consciousness, color, and reflexes
- Blood pressure, oxygen saturation, and pain
- Respiration, consciousness, and movement (Correct answer)
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 53: Which adjunct analgesic drug class works by blocking sodium channels in peripheral nerves and is used as part of a multimodal analgesia plan to reduce opioid requirements?
- COX-2 inhibitors
- NMDA antagonists
- Local anesthetics (e.g., IV lidocaine infusion) (Correct answer)
- Alpha-2 agonists
Correct answer: Local anesthetics (e.g., IV lidocaine infusion)
IV lidocaine infusions provide systemic analgesia via sodium channel blockade and anti-inflammatory mechanisms, reducing opioid consumption in the perioperative period.
Question 54: 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:
- Perform immediate re-intubation
- Apply 100% O2 via blow-by
- Administer racemic epinephrine via nebulizer
- Administer CPAP via facemask with 5–10 cmH2O (Correct answer)
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 55: Which warming method is considered most effective for treating mild to moderate post-operative hypothermia in the PACU?
- Forced-air warming devices (Correct answer)
- Warm blankets alone
- Warm IV fluids only

Question 56: Which condition is characterized by muscle rigidity, rapidly rising hyperthermia, and autonomic instability following anesthetic exposure?
- Serotonin syndrome
- Malignant hyperthermia (Correct answer)
- Thyroid storm
- 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 57: A PACU patient who received spinal anesthesia complains of inability to move her legs 2 hours post-procedure. Which assessment finding would be most concerning?
- Bilateral leg weakness with intact sensation
- Asymmetric motor block with increasing leg pain (Correct answer)
- Symmetric sensory block at T10
- Gradual return of sensation in toes
Correct answer: Asymmetric motor block with increasing leg pain
Asymmetric motor block with increasing pain may indicate spinal hematoma or abscess, which are neurological emergencies requiring immediate evaluation.
Question 58: 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 cognitive condition that exclusively affects pediatric surgical patients
- A permanent and irreversible condition affecting all surgical patients uniformly
- A planned sedation effect that affects all age groups equally
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 59: When caring for a patient with a regional nerve block in the PACU, the nurse's primary neurovascular assessment should include:
- Blood pressure comparison between bilateral extremities
- Level of consciousness and pupillary response
- Capillary refill, pulses, sensation, and motor function distal to the block (Correct answer)
- Deep tendon reflex testing at the patellar and Achilles tendons
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 60: When documenting the use of physical restraints in the PACU, which element is REQUIRED by Joint Commission standards?
- Only the physician's order without nursing assessment
- The clinical justification, type of restraint, time applied, neurovascular checks, and patient response (Correct answer)
- The family's verbal agreement overheard in the waiting room
- The cost of the restraint device used
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 61: Informed consent for a procedure was obtained before the patient received sedation in the PACU. Upon reflection, the nurse suspects the patient may not have been fully competent when signing. The nurse should:
- Trust that the provider obtained it appropriately
- Proceed with the procedure and document observations
- Ask the patient to sign a new consent form
- Notify the surgeon and document the concern for clinical review (Correct answer)
Correct answer: Notify the surgeon and document the concern for clinical review
Valid informed consent requires decision-making capacity; if the nurse suspects the patient lacked capacity when signing, this must be reported for clinical and ethical review.
Question 62: What is one of the financial benefits associated with CPAN certification?
- Guaranteed salary increase
- Potential for higher wages due to specialized expertise (Correct answer)
- Direct payment for continuing education courses
- Eligibility for government grants
Correct answer: Potential for higher wages due to specialized expertise
While not a guaranteed salary increase, CPAN certification often leads to a potential for higher wages. Employers recognize the value of specialized expertise and commitment to professional development, which can translate into better compensation and benefits for certified nurses.
Question 63: 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
- Rule out hypoxia and hypercapnia as contributing factors before treating (Correct answer)
- Assess for concurrent emergence delirium from volatile anesthetics
- 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 64: A PACU patient reports a pain score of 8/10 after receiving opioids. What should the nurse assess first?
- Ask the patient to wait 30 minutes
- Apply ice packs to the surgical site
- Respiratory rate and oxygen saturation (Correct answer)
- Administer additional opioids immediately
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 65: Which factor most increases a PACU patient's risk for post-extubation respiratory complications?
- Obstructive sleep apnea (OSA) (Correct answer)
- History of mild seasonal allergies
- BMI of 24
- Recent viral upper respiratory infection resolved 4 weeks ago
Correct answer: Obstructive sleep apnea (OSA)
Obstructive sleep apnea significantly increases the risk of post-extubation airway collapse and respiratory depression, especially with residual opioids and sedatives.
Question 66: A core body temperature below which value defines severe hypothermia?

- Constipation
- Urinary retention
Correct answer: Respiratory depression
Respiratory depression is the most serious and potentially life-threatening side effect of opioid administration in the PACU.
Question 106: A nurse documents 'patient appears comfortable' without recording a numerical pain score. Which legal principle does this documentation MOST violate?
- The principle of beneficence in nursing ethics
- The principle of patient autonomy
- 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 107: What is bronchospasm in the post-anesthesia setting and how is it treated?
- A completely normal physiologic response to extubation requiring no treatment
- 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)
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.

- Prone position to improve FRC and oxygenation
- Supine with legs elevated to improve cardiac output
- Reverse Trendelenburg or head-of-bed elevated 30–45 degrees (Correct answer)
Correct answer: Reverse Trendelenburg or head-of-bed elevated 30–45 degrees
Elevating the head of bed in obese patients reduces diaphragmatic pressure from abdominal contents, improving functional residual capacity and oxygenation.
Question 111: What is equianalgesic dosing in PACU practice?
- Converting between different opioids using dose equivalency tables (Correct answer)
- Using the same medication at the same dose for every patient
- Administering opioids at equal fixed time intervals
- Administering equal doses of all pain medications simultaneously
Correct answer: Converting between different opioids using dose equivalency tables
Equianalgesic dosing uses conversion tables to calculate equivalent analgesic doses when switching between different opioid medications.
Question 112: 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:
- Administer nebulized racemic epinephrine
- Apply CPAP at 10 cmH2O
- Open the surgical wound to relieve tracheal compression (Correct answer)
- Prepare for emergent reintubation
Correct answer: Open the surgical wound to relieve tracheal compression
Post-thyroid surgery stridor may indicate hematoma compressing the trachea; opening the wound to decompress is a life-saving emergency intervention while preparing definitive airway management.
Question 113: How does post-operative atelectasis typically present in the PACU?
- 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
- Markedly increased urine output with normal respiratory status
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 114: Which PACU nursing intervention MOST directly reduces the risk of ventilator-associated pneumonia (VAP) in a mechanically ventilated patient?
- Administering prophylactic antibiotics every six hours
- Suctioning the airway every hour on a scheduled basis
- Maintaining head-of-bed elevation at 30–45 degrees (Correct answer)
- Using heated humidification in the ventilator circuit
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 115: Which assessment finding in the PACU indicates the patient has achieved adequate reversal of neuromuscular blockade?
- SpO2 of 95% on room air
- Train-of-four ratio ≥0.9 (Correct answer)
- ETCO2 of 45 mmHg
- Respiratory rate of 12 breaths/min
Correct answer: Train-of-four ratio ≥0.9
A train-of-four ratio ≥0.9 indicates adequate neuromuscular recovery and is the standard criterion for confirming reversal of neuromuscular blockade.

- Dopamine
- Phenylephrine (Correct answer)
- Epinephrine
- Norepinephrine
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 117: 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 promethazine 25 mg IV push (Correct answer)
- Turn the patient to the lateral position to prevent aspiration
- Administer ondansetron 4 mg IV per protocol
- Administer metoclopramide to promote gastric motility
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 118: Which nursing intervention best prevents post-operative atelectasis in PACU patients?
- Administering prophylactic bronchodilators to all patients
- Keeping patients supine to minimize respiratory effort
- Encouraging incentive spirometry and deep breathing exercises every 1-2 hours (Correct answer)
- Restricting fluid intake to minimize pulmonary edema
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 119: Unexplained hyperthermia in the PACU should prompt the nurse to first assess for which condition?
- Hyperglycemia
- Malignant hyperthermia or infection (Correct answer)
- Hypertension
- 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 120: How does a PACU nurse differentiate pain-related hypertension from a hypertensive crisis?
- Hypertensive crisis is always mild and resolves spontaneously without any intervention
- Pain-related hypertension typically resolves with adequate analgesia, while hypertensive crisis persists despite pain control and may require specific antihypertensive therapy (Correct answer)
- Pain-related hypertension is always more dangerous clinically than a hypertensive crisis
- Both conditions present identically and are managed with the same interventions
Correct answer: Pain-related hypertension typically resolves with adequate analgesia, while hypertensive crisis persists despite pain control and may require specific antihypertensive therapy
Treating pain often normalizes pain-related hypertension, whereas true hypertensive crisis persists despite adequate pain management and requires targeted antihypertensive treatment.
Question 121: What role does nonverbal communication play in professional interactions?
- It only matters during presentations
- It conveys up to 70% of the message and must align with verbal communication (Correct answer)
- It replaces the need for verbal communication
- It is irrelevant in professional settings
Correct answer: It conveys up to 70% of the message and must align with verbal communication
Nonverbal cues including body language, tone, and facial expressions significantly impact how messages are received and interpreted.
Question 122: Which pharmacologic property determines how quickly an inhalational anesthetic is taken up and eliminated from the body?
- Molecular weight
- Minimum alveolar concentration (MAC)
- Blood/gas partition coefficient (Correct answer)
- Vapor pressure
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 123: Which finding in a post-laparoscopic patient would alert the PACU nurse to possible pneumothorax?
- Bradycardia with hypertension
- Bilateral crackles on auscultation
- Distended neck veins without respiratory distress
- Unilateral absent breath sounds with tracheal deviation (Correct answer)
Correct answer: Unilateral absent breath sounds with tracheal deviation
Absent unilateral breath sounds with tracheal deviation toward the opposite side are hallmark signs of tension pneumothorax requiring emergent intervention.
Question 124: Which assessment tool is most commonly used to evaluate cognitive function?
- Glasgow Coma Scale only
- Body Mass Index (BMI)
- Visual Analog Scale (VAS)
- Mini-Mental State Examination (MMSE) (Correct answer)
Correct answer: Mini-Mental State Examination (MMSE)
The MMSE is widely used to screen for cognitive impairment and track changes in cognitive function over time.
Question 125: 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)
- Voided at least 200 mL urine spontaneously
- Completed at least 2 hours in Phase I recovery
- A Numeric Rating Scale pain score of 0
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 126: What should be done if an error is discovered in a patient record?
- Use white-out to cover the mistake
- Ignore it if no one has noticed
- Remove the page and rewrite it
- Draw a single line through the error, correct it, and initial with date (Correct answer)
Correct answer: Draw a single line through the error, correct it, and initial with date
The standard correction method preserves the original entry while making the correction transparent and traceable.
Question 127: A CPAN nurse disagrees with a discharge order but all clinical criteria are met. After voicing concerns to the surgeon, the most appropriate next step if still concerned is to:
- Call the patient's family to intervene
- Document the concern thoroughly and escalate to the charge nurse or patient safety officer (Correct answer)
- Refuse to process the discharge until a second opinion is obtained
- Discharge the patient and say nothing further
Correct answer: Document the concern thoroughly and escalate to the charge nurse or patient safety officer
When clinical concerns persist after initial advocacy, escalation through the chain of command and thorough documentation ensures patient safety and professional accountability.
Question 128: Which medication is commonly used as first-line pharmacologic treatment for PONV in the PACU?
- Morphine sulfate
- Ondansetron (Zofran) (Correct answer)

- Fentanyl (Correct answer)
- Morphine
- Hydromorphone
- Meperidine
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 133: Which of the following best describes the PACU nurse's responsibility regarding informed consent for a procedure ordered post-operatively?
- 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
- Obtain consent since the patient is in their care
- Have the patient sign consent upon discharge to Phase II
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 134: Dexmedetomidine exerts its sedative and analgesic effects primarily through which receptor?
- NMDA receptor
- Alpha-2 adrenergic receptor (Correct answer)
- GABA-A receptor
- Mu opioid 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 135: A patient in the PACU develops inspiratory stridor. What is the most likely cause and priority intervention?
- Allergic reaction to anesthesia requiring immediate antihistamine administration
- Post-operative nausea and vomiting requiring antiemetic administration
- Laryngospasm or airway obstruction requiring immediate airway repositioning and positive pressure ventilation if needed (Correct answer)
- Post-operative hypotension requiring intravenous fluid bolus
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 136: Which type of precaution is used for ALL patient encounters regardless of diagnosis?
- Airborne precautions
- Contact precautions only
- Standard precautions (Correct answer)
- Droplet precautions only
Correct answer: Standard precautions

Question 137: A PACU patient who received spinal anesthesia has a block level at T6 and develops bradycardia (HR 42 bpm) and hypotension. The nurse anticipates administering:
- Labetalol and nitroglycerin
- Atropine and IV fluid bolus (Correct answer)
- Diltiazem IV infusion
- Digoxin 0.25 mg IV
Correct answer: Atropine and IV fluid bolus
High spinal block can cause sympathectomy leading to bradycardia and hypotension, treated with atropine for the heart rate and IV fluids or vasopressors for blood pressure.
Question 138: A patient is prescribed transdermal fentanyl for chronic pain management. In the PACU, the nurse notes a slow respiratory rate. What factor about this formulation is most important to consider?
- The patch delivers drug only while the patient is awake
- The patch is cleared immediately by the liver
- The depot in subcutaneous fat continues releasing fentanyl even after patch removal, prolonging effects (Correct answer)
- Heating the patch area decreases absorption
Correct answer: The depot in subcutaneous fat continues releasing fentanyl even after patch removal, prolonging effects
Transdermal fentanyl creates a subcutaneous depot that continues to release drug into systemic circulation for hours after patch removal, making overdose management prolonged.
Question 139: Which pharmacologic agent is the drug of choice for treating bronchospasm in the PACU?
- Aminophylline 250 mg IV
- Albuterol via nebulizer or MDI (Correct answer)

- A sign indicating adequate intraoperative pain control was achieved
- A planned and expected component of the anesthesia recovery process
- Normal sedation expected to follow all types of general anesthesia
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 142: 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 objectively evaluate recovery using criteria including activity, respiration, circulation, consciousness, and oxygen saturation (Correct answer)
- To assess surgical wound healing and readiness for staple removal
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 143: A PACU patient requests that their HIV status not be disclosed to their spouse who is present. The nurse should:
- Ask the physician to disclose the information
- Document the request and inform the charge nurse only
- Respect the patient's confidentiality and not disclose without the patient's consent (Correct answer)
- Tell the spouse because they may be at risk
Correct answer: Respect the patient's confidentiality and not disclose without the patient's consent
Patient confidentiality is protected by HIPAA and ethical principles; the nurse must respect the patient's right to control their health information except in specific legally mandated circumstances.
Question 144: Which medication reverses opioid-induced respiratory depression in PACU patients?
- Sugammadex
- Naloxone (Correct answer)
- Neostigmine
- Flumazenil
Correct answer: Naloxone
Naloxone (Narcan) is the opioid antagonist used to reverse opioid-induced respiratory depression in the PACU.
Question 145: The ethical concept of 'fidelity' in nursing practice refers to:
- Equal treatment of all patients regardless of status
- Keeping promises and honoring commitments to patients (Correct answer)
- Acting in the patient's best interest without their input
- Telling the truth even when it is difficult
Correct answer: Keeping promises and honoring commitments to patients
Fidelity means keeping promises, fulfilling duties, and honoring commitments made to patients, which is foundational to the nurse-patient trust relationship.
Question 146: Which of the following best describes the legal concept of 'charting by exception' in PACU documentation?
- Skipping documentation when a patient is stable
- Documenting only abnormal findings and deviations from expected outcomes, with normal findings assumed unless noted (Correct answer)
- Documenting every assessment finding in full narrative form
- Charting only the exceptions to facility policy
Correct answer: Documenting only abnormal findings and deviations from expected outcomes, with normal findings assumed unless noted
Charting by exception documents only abnormal findings, with normal assessment results implied by the absence of documented deviations.
Question 147: A PACU nurse is reviewing a patient's chart and notes that prophylactic heparin was ordered but not administered on the surgical floor. Which patient safety concern does this MOST directly address?
- Surgical site infection prevention
- Prevention of postoperative hemorrhage
- Reduction of postoperative atelectasis risk
- Deep vein thrombosis and pulmonary embolism prevention (Correct answer)
Correct answer: Deep vein thrombosis and pulmonary embolism prevention
Prophylactic anticoagulation with heparin is prescribed to prevent venous thromboembolism (DVT and PE), which is a leading cause of preventable postoperative death.
Question 148: When managing a PACU patient in pulseless ventricular tachycardia, what is the correct energy setting for the first biphasic defibrillation attempt?
- 120–200 J (Correct answer)
- 360 J
- 50–100 J
- 300 J
Correct answer: 120–200 J
Current AHA guidelines recommend 120–200 J for the first biphasic defibrillation shock for pulseless VT/VF.
Question 149: A patient in the PACU has a urine output of 15 mL over the past hour following a 4-hour abdominal surgery. Blood pressure is 110/70 mmHg and HR is 88 bpm. The nurse should:
- Reassure the patient that output will improve as anesthesia wears off
- Assess for bladder distension and notify the provider if no improvement (Correct answer)
- Restrict IV fluids to prevent fluid overload
- Insert a urinary catheter immediately without physician order
Correct answer: Assess for bladder distension and notify the provider if no improvement
Oliguria (<0.5 mL/kg/hr) in the PACU warrants assessment for bladder distension or urinary retention and prompt provider notification if not resolved.
Question 150: 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:
- Malignant hyperthermia
- Pseudocholinesterase deficiency (Correct answer)
- Opioid-induced respiratory depression
- Residual non-depolarizing blockade
Correct answer: Pseudocholinesterase deficiency
Pseudocholinesterase (butyrylcholinesterase) deficiency impairs succinylcholine metabolism, resulting in prolonged neuromuscular blockade lasting hours.
Question 151: Which accreditation concept requires that PACU processes be continuously monitored and improved, not just evaluated during survey periods?
- Conditional accreditation probation
- Sentinel event root cause analysis
- Periodic Performance Review (PPR)
- Ongoing Performance Improvement (PI) (Correct answer)
Correct answer: Ongoing Performance Improvement (PI)
Performance Improvement (PI) requirements mandate that facilities continuously collect data, analyze trends, and implement improvements between accreditation surveys.
Question 152: A patient is transitioning from IV to oral opioids. To safely convert IV morphine 4 mg to oral oxycodone, the nurse knows the oral bioavailability difference requires approximately which conversion?
- IV morphine 4 mg = oral oxycodone 20 mg
- IV morphine 4 mg = oral oxycodone 4 mg
- IV morphine 4 mg = oral oxycodone 2 mg
- IV morphine 4 mg = oral oxycodone 6–8 mg (Correct answer)
Correct answer: IV morphine 4 mg = oral oxycodone 6–8 mg
IV morphine 4 mg converts to approximately 12 mg oral morphine (3:1 ratio), and oral morphine to oral oxycodone is approximately 1:0.67, yielding about 6–8 mg oxycodone.
Question 153: Which set of conditions is REQUIRED for effective steam sterilization (autoclave) of surgical instruments?
- 100°C temperature, atmospheric pressure, 60-minute exposure time

Incentive spirometry and deep breathing exercises promote alveolar expansion and are the most effective interventions for preventing post-operative atelectasis.
Question 156: 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
- Draw a single line through the error, write the correction, and add initials, date, and 'error' notation (Correct answer)
- Remove the page and rewrite the entire note correctly
- Use correction fluid (white-out) to cover the error and write the correct information
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 157: In the PACU, a patient receiving a heparin infusion after vascular surgery develops oozing from IV sites and hematuria. The nurse suspects heparin-induced coagulopathy and expects which laboratory finding?
- Supratherapeutic aPTT greater than 120 seconds (Correct answer)
- Elevated INR and prolonged aPTT
- 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 158: Perioperative hypothermia is most directly associated with which post-operative complication?
- Hypertensive crisis
- Pulmonary embolism
- Acute renal failure
- Increased wound infection risk (Correct answer)
Correct answer: Increased wound infection risk
Hypothermia impairs immune function and reduces tissue oxygen delivery, significantly increasing the risk of surgical site infection.
Question 159: Which of the following BEST describes the relationship between CPAN certification and facility accreditation?
- Accreditation replaces the need for individual specialty certifications
- They are complementary: certification validates individual competence, accreditation validates organizational systems (Correct answer)
- They are entirely independent with no influence on each other
- CPAN certification is required for a facility to obtain accreditation
Correct answer: They are complementary: certification validates individual competence, accreditation validates organizational systems
CPAN certification demonstrates individual nurse competence, while accreditation demonstrates that the organization's systems and environment support quality care—both are complementary.
Question 160: 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)
- Setting the medication dose independently without an order
- Pressing the PCA button for the patient when they appear uncomfortable
- Disabling the lockout mechanism for patients with severe pain
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 161: A PACU patient develops sudden onset of stridor and progressive hoarseness 20 minutes post-extubation. What is the most likely cause?
- Subglottic edema (Correct answer)
- Laryngospasm
- Vocal cord paralysis
- Bronchospasm
Correct answer: Subglottic edema
Post-extubation subglottic edema (croup) presents with stridor and hoarseness and is caused by mucosal irritation from the endotracheal tube.
Question 162: A post-cardiac surgery patient in the PACU develops cardiac tamponade. Which hemodynamic pattern is most consistent with this diagnosis?
- Low CVP with hypotension and tachycardia
- Hypertension with bradycardia and irregular rhythm
- Widened pulse pressure with elevated CVP
- Beck's triad: hypotension, muffled heart sounds, elevated JVD (Correct answer)
Correct answer: Beck's triad: hypotension, muffled heart sounds, elevated JVD
Beck's triad — hypotension, muffled heart sounds, and elevated jugular venous distension — is the classic presentation of cardiac tamponade.
Question 163: Why is pain reassessment after interventions essential in the PACU?
- It is required solely to fulfill hospital policy requirements
- It determines intervention effectiveness and guides further treatment decisions (Correct answer)
- It is done to delay discharge from the PACU for safety reasons
- It is performed only if the patient complains again after treatment
Correct answer: It determines intervention effectiveness and guides further treatment decisions
Pain reassessment after interventions allows the nurse to evaluate whether pain management was effective and adjust the treatment plan as needed.
Question 164: Which intervention is the gold standard for confirming correct endotracheal tube placement in a PACU patient requiring reintubation?
- Chest rise with ventilation
- Bilateral breath sounds on auscultation
- Continuous waveform capnography with CO2 detection (Correct answer)
- SpO2 improvement following intubation
Correct answer: Continuous waveform capnography with CO2 detection
Continuous waveform capnography is the gold standard for confirming endotracheal tube placement because it provides real-time CO2 waveform data that unequivocally confirms tracheal intubation.
Question 165: What does the term "half-life" refer to in pharmacology?
- The time until the drug expires
- The point at which a drug reaches maximum effectiveness
- The time between two doses
- 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 166: What is the primary pain assessment tool recommended for use in post-anesthesia care units (PACUs)?
- Numeric Rating Scale (NRS) (Correct answer)
- Braden Scale
- Ramsay Sedation Scale
- Glasgow Coma Scale
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 167: A patient in the PACU following abdominal surgery has a urine output of 15 mL/hour for 2 consecutive hours. Which assessment finding would best help differentiate prerenal from intrinsic renal failure?
- Urine specific gravity > 1.020
- Serum creatinine > 2.0 mg/dL
- Urine sodium < 10 mEq/L (Correct answer)
- Presence of red cell casts in urine
Correct answer: Urine sodium < 10 mEq/L
Urine sodium < 10 mEq/L indicates the kidney is reabsorbing sodium maximally, suggesting prerenal azotemia rather than intrinsic renal damage.
Question 168: After administering rocuronium-assisted intubation, the anesthesiologist orders sugammadex for reversal. Which patient condition is a contraindication to sugammadex administration?
- Hepatic insufficiency
- Renal failure requiring dialysis
- Known hypersensitivity to sugammadex (Correct answer)
- Age over 75 years
Correct answer: Known hypersensitivity to sugammadex
Known hypersensitivity or allergy to sugammadex is the primary contraindication, as severe anaphylaxis has been reported.
Question 169: Which assessment finding most suggests upper airway obstruction in a PACU patient?
- Inspiratory stridor with paradoxical chest and abdominal movement (Correct answer)
- Decreased SpO2 with productive cough
- Mild expiratory wheezing bilaterally
- Regular respiratory rate of 14 breaths/minute with clear breath sounds
Correct answer: Inspiratory stridor with paradoxical chest and abdominal movement
Inspiratory stridor and paradoxical chest-abdominal movement (chest falls while abdomen rises on inspiration) are classic signs of upper airway obstruction.
Question 170: 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 can cause aspiration, wound dehiscence, increased intracranial pressure, and significant patient distress (Correct answer)
- It is a minor inconvenience with no serious clinical significance
- 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 171: 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?
- 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
- Temperature of 37.8°C (100°F)
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 172: The CPAN is caring for a patient post-carotid endarterectomy. Which neurological finding requires IMMEDIATE provider notification?
- Blood pressure of 145/88 mmHg
- Complaint of mild incisional pain at the neck
- New unilateral facial droop and arm weakness (Correct answer)
- Mild drowsiness as anesthesia wears off
Correct answer: New unilateral facial droop and arm weakness
New focal neurological deficits after carotid endarterectomy indicate possible cerebral ischemia or stroke and constitute a neurovascular emergency.
Question 173: What is opioid tolerance and how does it affect post-anesthesia pain management?
- Decreased analgesic effect requiring higher doses to achieve the same pain relief (Correct answer)
- An allergy to opioid medications requiring avoidance
- The ability to metabolize opioids more rapidly than average
- A contraindication to opioid use in the post-operative setting
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 174: Which criterion must be met before a patient can be safely discharged from a Phase I PACU to Phase II or an inpatient unit?
- Patient must be fully awake and oriented to person, place, and time
- Patient must have resumed oral intake without nausea
- Patient must meet facility-approved discharge scoring criteria such as a Modified Aldrete Score of ≥9 (Correct answer)
- Patient must ambulate to the bathroom independently
Correct answer: Patient must meet facility-approved discharge scoring criteria such as a Modified Aldrete Score of ≥9
Discharge from Phase I PACU requires meeting a validated scoring threshold (e.g., Modified Aldrete ≥9) that ensures adequate recovery of vital functions per ASPAN standards.
Question 175: A patient with known obstructive sleep apnea arrives in the PACU after general anesthesia. Which positioning measure is MOST important?
- Place the patient in Trendelenburg to increase venous return
- Keep the patient flat to prevent hypotension
- Position the patient semi-upright (30–45 degrees) or lateral (Correct answer)
- Keep the patient supine with a pillow under the knees
Correct answer: Position the patient semi-upright (30–45 degrees) or lateral
Semi-upright or lateral positioning reduces upper airway collapse in OSA patients by decreasing the effect of gravity on oropharyngeal soft tissues.
