Accepted Answer

Decreased breath sounds, reduced oxygen saturation, and possible fever

Incentive spirometry and deep breathing exercises promote alveolar expansion and are the most effective interventions for preventing post-operative atelectasis.

Question 4

What is malignant hyperthermia (MH) and why is it considered a critical PACU emergency?

Accepted Answer

A potentially fatal hypermetabolic reaction to certain anesthetic agents characterized by hyperthermia, muscle rigidity, and acidosis

Answer

Malignant hyperthermia is a life-threatening pharmacogenetic disorder triggered by volatile anesthetics and succinylcholine, causing uncontrolled skeletal muscle metabolism.

Question 5
