Free CPAN Sample Questions and Answers

Question 1: Airway Obstruction 

A 58-year-old patient arrives in Phase I PACU following laparoscopic cholecystectomy. The patient is snoring loudly, oxygen saturation is 88%, and chest movement is minimal. Which action should the CPAN nurse perform first?

A. Apply a nonrebreather mask
B. Administer naloxone
C. Perform a jaw-thrust maneuver and reposition the airway
D. Call the surgeon

Correct Answer: C

Explanation:

Upper airway obstruction from tongue relaxation is common immediately after anesthesia. Snoring and decreased chest excursion indicate airway collapse. The priority is restoring airway patency using a jaw-thrust or chin-lift maneuver while maintaining cervical alignment. Oxygen alone will not correct obstruction if airflow is compromised. Naloxone is appropriate only when opioid-induced respiratory depression is suspected after ensuring airway support. Early airway repositioning frequently resolves hypoxemia and prevents progression to respiratory arrest. CPAN nurses should always follow ABC priorities, addressing airway issues before moving to breathing and circulation interventions.

Question 2: Malignant Hyperthermia

During recovery, a patient develops muscle rigidity, tachycardia, rising end-tidal CO₂, and a temperature of 103°F (39.4°C). Which medication should be administered immediately?

A. Succinylcholine
B. Dantrolene sodium
C. Atropine
D. Epinephrine

Correct Answer: B

Explanation:

Malignant hyperthermia is a life-threatening hypermetabolic reaction usually triggered by volatile anesthetics or succinylcholine. Early signs include increased end-tidal CO₂, muscle rigidity, tachycardia, and hyperthermia. Dantrolene sodium is the only specific treatment and should be administered immediately while discontinuing triggering agents. Additional interventions include cooling measures, correcting acidosis, monitoring potassium levels, and providing oxygen. Succinylcholine can worsen the condition. Rapid recognition by the CPAN nurse significantly reduces mortality and prevents complications such as arrhythmias, renal failure, and disseminated intravascular coagulation.

Question 3: Postoperative Hypotension

A patient recovering from total hip replacement has a blood pressure of 82/48 mmHg, pulse 118/min, and pale, cool skin. Which cause should the nurse suspect first?

A. Anxiety
B. Internal bleeding and hypovolemia
C. Hyperglycemia
D. Urinary retention

Correct Answer: B

Explanation:

Hypotension accompanied by tachycardia and cool skin suggests inadequate circulating volume. Postoperative bleeding is a common cause after orthopedic procedures. Internal hemorrhage can lead to shock if not recognized promptly. Anxiety typically causes hypertension rather than profound hypotension. Hyperglycemia and urinary retention rarely produce these signs. The CPAN nurse should assess surgical drains, dressings, and laboratory values while notifying the anesthesia provider and surgeon. Prompt fluid replacement and possible blood transfusion may be required. Recognizing early signs of hypovolemic shock is critical in preventing organ dysfunction and cardiovascular collapse.

Question 4: Aldrete Scoring

Which criterion is included in the Modified Aldrete Score used for PACU discharge readiness?

A. Serum potassium level
B. Activity, respiration, circulation, consciousness, and oxygen saturation
C. White blood cell count
D. Urine output only

Correct Answer: B

Explanation:

The Modified Aldrete Score evaluates five categories: activity, respiration, circulation, consciousness, and oxygen saturation. Each category receives a score of 0–2, with a total score generally of 9 or higher indicating readiness for transfer from Phase I recovery. Laboratory values are not part of the scoring system. CPAN nurses use this tool to assess recovery from anesthesia objectively. Although clinical judgment remains important, the Aldrete score provides a standardized method to ensure patients have regained sufficient respiratory and neurologic function before leaving the PACU.

Question 5: Opioid-Induced Respiratory Depression

A patient receiving IV hydromorphone becomes difficult to arouse and has a respiratory rate of 6 breaths/min. Which medication should be anticipated?

A. Flumazenil
B. Naloxone
C. Midazolam
D. Diphenhydramine

Correct Answer: B

Explanation:

Hydromorphone is an opioid, and severe sedation with respiratory depression is a medical emergency. Naloxone is an opioid antagonist that reverses respiratory depression. It should be administered cautiously and titrated because abrupt reversal may cause severe pain, hypertension, pulmonary edema, or withdrawal symptoms. Flumazenil reverses benzodiazepines, not opioids. CPAN nurses should simultaneously maintain airway patency, provide supplemental oxygen, and closely monitor respiratory status. Continuous reassessment is essential because naloxone’s duration may be shorter than that of the opioid, requiring repeated doses or infusion.

Question 6: Laryngospasm Case

A pediatric patient suddenly develops inspiratory stridor, retractions, and oxygen saturation of 84% after tonsillectomy. Which complication is most likely?

A. Pulmonary embolism
B. Laryngospasm
C. Atelectasis
D. Stroke

Correct Answer: B

Explanation:

Laryngospasm is a common postoperative airway emergency in pediatric patients, particularly after tonsillectomy. It involves involuntary closure of the vocal cords and presents with stridor, retractions, and hypoxia. Immediate interventions include providing 100% oxygen, applying positive pressure ventilation, suctioning secretions, and notifying anesthesia personnel. Severe cases may require succinylcholine and reintubation. Prompt recognition prevents progression to complete airway obstruction and cardiac arrest. CPAN nurses should remain vigilant because children have smaller airways and are at increased risk for rapid oxygen desaturation.

Question 7: Spinal Anesthesia Complication

Following spinal anesthesia, a patient reports severe headache that worsens when sitting upright and improves when lying flat. Which condition is most likely?

A. Cerebral hemorrhage
B. Post-dural puncture headache
C. Stroke
D. Sinusitis

Correct Answer: B

Explanation:

Post-dural puncture headache results from leakage of cerebrospinal fluid after spinal anesthesia. Symptoms are characteristically positional, worsening when upright and improving when supine. Associated symptoms may include nausea, neck stiffness, and photophobia. Conservative treatment includes hydration, caffeine, and analgesics. Persistent symptoms may require an epidural blood patch. CPAN nurses should recognize this complication promptly because it can significantly delay recovery and discharge. Early communication with anesthesia providers ensures timely intervention and improved patient comfort.

Question 8: Emergence Delirium

An elderly patient becomes confused, restless, and attempts to remove monitoring devices after surgery. What is the priority intervention?

A. Apply restraints immediately
B. Reorient the patient and assess oxygenation
C. Administer opioids first
D. Leave the patient alone

Correct Answer: B

Explanation:

Emergence delirium may result from hypoxia, pain, medications, or metabolic disturbances. Reorientation and assessment of oxygenation are priority interventions because hypoxemia is reversible and potentially life-threatening. Restraints should be used only when necessary for safety and after other measures fail. Pain and urinary retention should also be assessed. Elderly patients are especially susceptible to postoperative delirium because of age-related physiologic changes and medication sensitivity. CPAN nurses play an essential role in maintaining safety while identifying and correcting underlying causes.

Question 9: Residual Neuromuscular Blockade

Which assessment finding indicates residual neuromuscular blockade?

A. Strong handgrip and sustained head lift
B. Ability to cough effectively
C. Weak hand grasp and inability to sustain head lift for 5 seconds
D. Clear speech

Correct Answer: C

Explanation:

Residual paralysis following neuromuscular blocking agents can impair airway protection and ventilation. Inability to maintain a head lift for 5 seconds and weak hand grip suggest incomplete recovery. Patients may also have difficulty swallowing or coughing. CPAN nurses should assess muscle strength and respiratory function before extubation and transfer. Quantitative neuromuscular monitoring is increasingly recommended to prevent postoperative respiratory complications. Failure to recognize residual blockade can lead to airway obstruction and hypoventilation.

Question 10: PACU Pain Management

Which pain scale is recommended for a fully alert adult patient?

A. Glasgow Coma Scale
B. Numeric Rating Scale (0–10)
C. Braden Scale
D. Morse Fall Scale

Correct Answer: B

Explanation:

The Numeric Rating Scale allows patients to rate pain intensity from 0 to 10 and is widely used in PACU settings. Accurate pain assessment enables individualized analgesic therapy and improves outcomes. The Glasgow Coma Scale evaluates neurologic function, while Braden and Morse scales assess pressure injury and fall risk. CPAN nurses should combine pain scores with physiologic findings and patient preferences. Effective pain control enhances respiratory effort, mobility, and overall satisfaction during postoperative recovery.

Question 11: PACU Bradycardia

Which medication is commonly used to treat symptomatic bradycardia?

A. Atropine
B. Dantrolene
C. Naloxone
D. Protamine

Correct Answer: A

Explanation:

Atropine is the first-line medication for symptomatic bradycardia according to ACLS guidelines. It blocks vagal influences on the heart, increasing heart rate. Symptoms may include hypotension, altered mental status, chest pain, or poor perfusion. CPAN nurses should assess for causes such as vagal stimulation, medications, or hypoxia while preparing emergency equipment. Continuous ECG monitoring is essential. Prompt treatment prevents progression to cardiac arrest and ensures adequate tissue perfusion.

Question 12: Postoperative Nausea and Vomiting

Which patient has the highest risk for postoperative nausea and vomiting (PONV)?

A. Male smoker
B. Female nonsmoker with history of motion sickness
C. Male diabetic patient
D. Elderly male

Correct Answer: B

Explanation:

Risk factors for PONV include female sex, nonsmoking status, history of motion sickness or previous PONV, and postoperative opioid use. The female nonsmoker with motion sickness has multiple risk factors. Prevention strategies include multimodal antiemetics and minimizing opioid exposure. CPAN nurses should monitor hydration status and assess the effectiveness of antiemetic therapy. Early management improves patient comfort and reduces complications such as aspiration and delayed discharge.

Question 13: Hypothermia

A PACU patient has a temperature of 95°F (35°C) and is shivering. Which intervention is appropriate?

A. Cold compresses
B. Forced-air warming blanket
C. Restrict fluids
D. Increase room airflow

Correct Answer: B

Explanation:

Postoperative hypothermia increases oxygen consumption, cardiac workload, and risk of bleeding. Forced-air warming systems effectively restore normothermia and reduce shivering. Cold therapy would worsen hypothermia. CPAN nurses should monitor core temperature, provide warmed IV fluids when appropriate, and assess for complications. Maintaining normothermia improves coagulation, decreases surgical site infections, and enhances patient comfort.

Question 14: Obstructive Sleep Apnea

Patients with obstructive sleep apnea are at greatest risk for which complication after receiving opioids?

A. Hyperglycemia
B. Respiratory depression
C. Hypertension
D. Renal failure

Correct Answer: B

Explanation:

Patients with obstructive sleep apnea have increased susceptibility to opioid-induced respiratory depression because airway obstruction worsens during sedation. Continuous monitoring, supplemental oxygen, and cautious opioid administration are recommended. CPAN nurses should assess for episodes of apnea and encourage use of CPAP devices if prescribed. Early recognition prevents severe hypoxemia and cardiac complications.

Question 15: PACU Priority

Which patient should the CPAN nurse assess first?

A. Pain score of 8/10
B. Blood pressure 150/88 mmHg
C. Oxygen saturation 86% on 4 L nasal cannula
D. Mild nausea

Correct Answer: C

Explanation:

Airway and breathing always take priority. Oxygen saturation of 86% despite supplemental oxygen indicates significant hypoxemia requiring immediate assessment. Severe pain and hypertension are important but less urgent. CPAN nurses must use ABC principles to prioritize care and prevent respiratory failure. Rapid intervention may include airway repositioning, oxygen delivery adjustment, or notifying anesthesia personnel.

Question 16: Pediatric Airway Differences

Compared with adults, children are more prone to airway obstruction because they have:

A. Larger tracheas
B. Relatively larger tongues and smaller airways
C. Stronger respiratory muscles
D. Larger lungs

Correct Answer: B

Explanation:

Children have proportionally larger tongues, smaller airways, and higher oxygen consumption rates, making them susceptible to airway obstruction and rapid desaturation. CPAN nurses caring for pediatric patients should maintain proper positioning and monitor respiratory status closely. Early intervention prevents severe hypoxia and respiratory arrest.

Question 17: Hemorrhage Recognition

Which finding suggests postoperative hemorrhage?

A. Increasing blood pressure and bradycardia
B. Tachycardia and decreasing urine output
C. Elevated temperature only
D. Increased appetite

Correct Answer: B

Explanation:

Tachycardia and oliguria are early signs of hypovolemia and hemorrhage. Reduced renal perfusion decreases urine output. CPAN nurses should assess dressings, drains, hemodynamic status, and laboratory values. Early intervention may include fluid resuscitation and blood products. Delayed recognition can progress to shock and organ failure.

Question 18: Flumazenil Use

Flumazenil reverses which medication class?

A. Opioids
B. Benzodiazepines
C. NSAIDs
D. Beta blockers

Correct Answer: B

Explanation:

Flumazenil antagonizes benzodiazepines such as midazolam and diazepam. It is used when excessive sedation causes respiratory compromise. Because it may precipitate seizures in chronic benzodiazepine users, careful monitoring is necessary. CPAN nurses should maintain airway support and observe for resedation because the duration of flumazenil may be shorter than the benzodiazepine involved.

Question 19: Aspiration Risk

Which patient has the highest aspiration risk?

A. Awake patient with intact gag reflex
B. Sedated patient with impaired protective reflexes
C. Ambulating patient
D. Patient with mild headache

Correct Answer: B

Explanation:

Loss of protective airway reflexes increases aspiration risk. Sedation impairs swallowing and coughing mechanisms, allowing gastric contents to enter the lungs. CPAN nurses should position patients appropriately, suction secretions as needed, and monitor for respiratory distress. Prevention of aspiration reduces morbidity and mortality.

Question 20: PACU Discharge Criteria

Before discharge from Phase I recovery, which finding is essential?

A. Complete absence of pain
B. Stable vital signs and adequate oxygenation
C. Ability to eat a meal
D. Normal bowel movement

Correct Answer: B

Explanation:

Patients do not need to be pain-free before leaving PACU, but they must demonstrate stable cardiovascular and respiratory status, adequate oxygenation, and recovery of consciousness appropriate for their condition. Discharge criteria are often guided by the Modified Aldrete Score. CPAN nurses ensure safe transfer by verifying physiologic stability and identifying unresolved complications. Proper discharge assessment reduces readmissions and postoperative adverse events.

Question 21: Negative Pressure Pulmonary Edema 

A 34-year-old patient experiences severe laryngospasm after extubation. Thirty minutes later, the patient develops dyspnea, crackles, and pink frothy sputum. Which complication should the CPAN nurse suspect?

A. Aspiration pneumonia
B. Pulmonary embolism
C. Negative pressure pulmonary edema
D. Acute myocardial infarction

Correct Answer: C

Explanation:

Negative pressure pulmonary edema (NPPE) can occur following forceful inspiratory efforts against an obstructed airway, such as during laryngospasm. The increased intrathoracic negative pressure causes fluid to shift into the alveoli, resulting in pulmonary edema. Symptoms include hypoxemia, respiratory distress, crackles, and pink frothy sputum. Treatment focuses on maintaining oxygenation, applying positive pressure ventilation, and, in severe cases, reintubation and mechanical ventilation. Prompt recognition by the CPAN nurse is essential because NPPE usually resolves with supportive care but may rapidly become life-threatening if untreated.

Question 22: Local Anesthetic Systemic Toxicity 

Following a peripheral nerve block, a patient complains of tinnitus, metallic taste, and circumoral numbness before developing seizures. What should the nurse suspect?

A. Stroke
B. Hypoglycemia
C. Local anesthetic systemic toxicity
D. Myocardial infarction

Correct Answer: C

Explanation:

Tinnitus, metallic taste, circumoral numbness, and seizures are classic manifestations of local anesthetic systemic toxicity (LAST). In severe cases, cardiac arrhythmias and cardiovascular collapse may occur. Immediate management includes stopping anesthetic administration, maintaining airway support, controlling seizures, and initiating lipid emulsion therapy. Early recognition dramatically improves outcomes. CPAN nurses should be aware that symptoms may initially appear neurologic before progressing to cardiovascular instability. Continuous monitoring after regional anesthesia is essential to detect toxicity promptly.

Question 23: Postoperative Urinary Retention

Which patient is at greatest risk for postoperative urinary retention?

A. Young patient undergoing cataract surgery
B. Male patient with benign prostatic hyperplasia after spinal anesthesia
C. Female patient receiving local anesthesia
D. Pediatric patient after ear tube placement

Correct Answer: B

Explanation:

Spinal anesthesia temporarily blocks bladder sensation and detrusor muscle function. Male patients with benign prostatic hyperplasia already have impaired urinary flow, significantly increasing their risk of urinary retention. Symptoms include suprapubic discomfort, inability to void, and bladder distention. CPAN nurses should monitor intake and output and assess bladder fullness when retention is suspected. Ultrasound bladder scanning is commonly used before catheterization. Untreated urinary retention can lead to bladder overdistension and infection.

Question 24: Neurologic Assessment

A patient remains unresponsive 45 minutes after surgery despite stable vital signs and adequate oxygenation. Which cause should be investigated first?

A. Residual anesthetic effects
B. Anxiety
C. Hypertension
D. Constipation

Correct Answer: A

Explanation:

Delayed emergence is commonly caused by residual anesthetic agents, sedatives, or opioids. Hypoglycemia, electrolyte disturbances, and neurologic events should also be considered if recovery is unexpectedly prolonged. CPAN nurses should evaluate oxygenation, blood glucose levels, medications administered, and neurologic status. Anxiety does not cause prolonged unconsciousness. Prompt identification of delayed emergence helps prevent complications and ensures appropriate interventions, including reversal agents when indicated.

Question 25: PACU Arrhythmia

Frequent premature ventricular contractions (PVCs) are noted on the monitor. Which electrolyte imbalance most commonly contributes to this rhythm disturbance?

A. Hypercalcemia
B. Hypokalemia
C. Hypernatremia
D. Hypermagnesemia

Correct Answer: B

Explanation:

Hypokalemia increases myocardial irritability and predisposes patients to ventricular ectopy and dysrhythmias. Frequent PVCs may progress to ventricular tachycardia if left untreated. CPAN nurses should assess electrolyte values, oxygenation, and medication history while continuously monitoring cardiac rhythm. Potassium replacement may be required under provider supervision. Early intervention prevents more serious arrhythmias and maintains cardiovascular stability during recovery.
