AMERICAN BOARD OF PERIANESTHESIA NURSING CERTIFICATION (CPAN)
PRACTICE EXAM 2026 — 200 QUESTIONS
QUESTION 1: A patient arriving in the PACU after general anesthesia is
unresponsive to verbal stimuli but responds to painful stimuli. According to
the Aldrete scoring system, what score would this patient receive for the
consciousness category?
A. 0
B. 1
C. 2
D. 3
E. 4
CORRECT ANSWER: B. 1
EXPERT RATIONALE: The Aldrete scoring system scores consciousness on a scale
of 0–2. A score of 1 is assigned when the patient responds only to stimulation
,(tactile or painful). A score of 2 is given when the patient is fully awake and
oriented. A score of 0 is given when the patient is not responding at all.
QUESTION 2: A post-anesthesia patient develops sudden onset of stridor and
increasing respiratory distress 20 minutes after extubation. What is the most
likely cause?
A. Pulmonary embolism
B. Bronchospasm
C. Laryngospasm
D. Pneumothorax
E. Aspiration pneumonitis
CORRECT ANSWER: C. Laryngospasm
EXPERT RATIONALE: Laryngospasm is a common postoperative complication that
occurs when the vocal cords spasm and partially or completely close the airway. It
typically presents with stridor, increased respiratory effort, and oxygen
desaturation shortly after extubation. Immediate treatment includes jaw thrust,
positive pressure oxygen, and if severe, succinylcholine administration.
QUESTION 3: Which neuromuscular blocking agent reversal medication works
by encapsulating rocuronium and vecuronium molecules to reverse their
effects?
A. Neostigmine
B. Edrophonium
C. Pyridostigmine
D. Sugammadex
E. Atropine
CORRECT ANSWER: D. Sugammadex
,EXPERT RATIONALE: Sugammadex (Bridion) is a modified gamma-cyclodextrin that
encapsulates rocuronium and vecuronium molecules, forming a tight complex and
rapidly reversing neuromuscular blockade. Unlike neostigmine, it does not require
an anticholinergic agent and works independently of acetylcholinesterase
inhibition.
QUESTION 4: A PACU patient's SpO2 drops to 88% despite supplemental
oxygen via face mask at 10 L/min. The nurse notes absent breath sounds on
the left side. What condition should be suspected?
A. Pulmonary edema
B. Atelectasis
C. Tension pneumothorax
D. Hemothorax
E. Pleural effusion
CORRECT ANSWER: C. Tension pneumothorax
EXPERT RATIONALE: Tension pneumothorax presents with absent or decreased
breath sounds on the affected side, hypoxia, tracheal deviation, hypotension, and
distended neck veins. It is a life-threatening emergency requiring immediate needle
decompression followed by chest tube insertion. PACU nurses must recognize this
rapidly.
QUESTION 5: When caring for a patient who received spinal anesthesia, the
nurse notices blood pressure drops from 130/80 to 88/50 mmHg. What is the
priority intervention?
A. Administer morphine IV
B. Position the patient in Trendelenburg and administer IV fluids
C. Apply oxygen via nasal cannula
D. Notify the surgeon immediately
, E. Administer oral fluids
CORRECT ANSWER: B. Position the patient in Trendelenburg and
administer IV fluids
EXPERT RATIONALE: Hypotension following spinal anesthesia results from
sympathetic blockade causing vasodilation and venous pooling. The priority
intervention is IV fluid bolus and positioning to improve venous return.
Vasopressors such as ephedrine or phenylephrine may also be used. Oxygen is
supportive but not the primary intervention.
QUESTION 6: Which of the following best describes malignant hyperthermia
(MH)?
A. A postoperative infection caused by gram-positive organisms
B. A hypermetabolic crisis of skeletal muscle triggered by volatile anesthetics or
succinylcholine
C. Hyperthermia due to excessive warming blankets in the PACU
D. An allergic reaction to opioid analgesics
E. A neurological complication of regional anesthesia
CORRECT ANSWER: B. A hypermetabolic crisis of skeletal muscle triggered
by volatile anesthetics or succinylcholine
EXPERT RATIONALE: Malignant hyperthermia is a life-threatening
pharmacogenetic disorder where triggering agents (volatile anesthetics and
succinylcholine) cause uncontrolled skeletal muscle metabolism, leading to
hyperthermia, rigidity, acidosis, and hyperkalemia. Treatment includes dantrolene
sodium, cooling measures, and supportive care.
QUESTION 7: A patient in the PACU develops muscle rigidity, high fever
(40.2°C), tachycardia, and dark urine. What is the priority medication to
administer?
