Introduction
This comprehensive examination is meticulously designed to evaluate the advanced knowledge, critical reasoning,
and clinical judgment essential for perianesthesia nursing practice. It assesses competency across core domains,
including airway management, pharmacology, hemodynamic monitoring, and emergency response. The exam
employs a rigorous multiple-choice format interwoven with realistic, scenario-based questions that mirror the
complexities of the perianesthesia environment. Emphasis is placed on the application of evidence-based
guidelines, adherence to patient safety protocols, and the execution of sound clinical decisions. Success on this
,examination reflects a deep understanding of physiologic principles and the ability to synthesize data to ensure
optimal patient outcomes.
Section One: Questions 1–100
1. A patient in the PACU is exhibiting signs of upper airway obstruction characterized by snoring respirations
and paradoxical chest wall movement. What is the most appropriate initial intervention?
A. Insert an oral airway
B. Administer naloxone
C. Perform a jaw-thrust maneuver
D. Prepare for reintubation
🟢 C. Perform a jaw-thrust maneuver
🔴 RATIONALE: A jaw-thrust maneuver is the primary, non-invasive technique to relieve upper airway
obstruction caused by pharyngeal soft tissue collapse, especially in patients with suspected cervical spine injury
or those who are obtunded. It lifts the mandible and tongue forward, restoring airway patency without moving
the neck. While an oral airway is a subsequent step, the jaw-thrust is the immediate, manual intervention.
2. A patient’s arterial blood gas (ABG) reveals a pH of 7.28, PaCO2 of 55 mmHg, and HCO3- of 24 mEq/L.
Which condition is most consistent with these findings?
A. Metabolic acidosis
B. Metabolic alkalosis
,C. Respiratory acidosis
D. Respiratory alkalosis
🟢 C. Respiratory acidosis
🔴 RATIONALE: The ABG shows acidemia (pH < 7.35) with an elevated PaCO2 (> 45 mmHg), indicating a
primary respiratory acidosis. The HCO3- is within normal range, suggesting this is an acute process without
renal compensation. This pattern is often seen in hypoventilation, airway obstruction, or central nervous system
depression from residual anesthetics.
3. A patient develops sudden, severe hypertension, tachycardia, and muscle rigidity in the PACU. Which
medication should the nurse anticipate administering first?
A. Dantrolene sodium
B. Sodium bicarbonate
C. Diltiazem
D. Nifedipine
🟢 A. Dantrolene sodium
🔴 RATIONALE: These signs are classic indicators of malignant hyperthermia (MH), a life-threatening
hypermetabolic crisis. Dantrolene sodium is the specific and only effective antidote for MH, acting on the
ryanodine receptor to reduce calcium release from the sarcoplasmic reticulum. It must be administered
immediately. While other drugs may treat symptoms, dantrolene addresses the underlying pathophysiology.
4. The PACU nurse is assessing a patient who received general anesthesia with sevoflurane. Which finding is
most indicative of stage II (excitement) emergence?
, A. Patient is unresponsive to painful stimuli
B. Patient is oriented and following commands
C. Patient is thrashing and holding their breath
D. Patient has regular, deep respirations
🟢 C. Patient is thrashing and holding their breath
🔴 RATIONALE: Stage II of anesthesia, or the excitement/delirium stage, is characterized by irregular breathing,
breath-holding, uncontrolled movements, and laryngeal spasm. This is a high-risk period for aspiration and
injury. An unresponsive patient is indicative of Stage IV (overdose), orientation indicates Stage III (surgical), and
regular respirations are typical of Stage I (analgesia).
5. A patient in the PACU is complaining of severe, continuous pain at the surgical site, rated as an 8 on a 0-10
scale. The nurse administers 2 mg of IV morphine. Thirty minutes later, the patient’s respirations are 8/min,
and they are difficult to arouse. What is the nurse’s priority action?
A. Administer flumazenil
B. Administer naloxone
C. Administer doxapram
D. Apply supplemental oxygen only
🟢 B. Administer naloxone
🔴 RATIONALE: The clinical picture of respiratory depression (RR 8/min) and sedation following opioid
administration is strongly suggestive of opioid-induced respiratory depression. Naloxone is the specific opioid
antagonist that reverses these effects. Flumazenil is for benzodiazepine reversal. Doxapram is a respiratory
stimulant but is not first-line. While oxygen is important, reversing the primary cause is the priority.
