The nurse is caring for a patient who has just been transferred to the PACU from the OR. What is the highest nursing priority?

Choice A reason: Assessing for hemorrhage is a critical nursing function in the immediate postoperative period. While internal or external bleeding can lead to hypovolemic shock, the physiological timeline for hemorrhage usually allows for a slightly longer window of intervention compared to the immediate lethality of an obstructed airway. Choice B reason: According to the ABC (Airway, Breathing, Circulation) prioritization framework, maintaining a patent airway is the absolute highest priority. Post-anesthesia patients are at high risk for airway obstruction due to tongue displacement, residual neuromuscular blockade, or laryngospasm, which can lead to rapid hypoxemia and cardiac arrest. Choice C reason: Pain management is essential for patient comfort and can prevent postoperative complications like hypertension or shallow breathing. However, it is a lower priority than physiological stabilization. The nurse must ensure the patient is breathing and hemodynamically stable before administering opioid analgesics that could further suppress respiration. Choice D reason: Assessing vital signs is a core component of PACU monitoring, but the frequency mentioned (every 30 minutes) is actually insufficient for the immediate postoperative phase, which usually requires monitoring every 5 to 15 minutes. Regardless, monitoring is a tool to identify problems, not an intervention like airway maintenance.
