What are early clinical signs of post-operative hemorrhage that a PACU nurse must monitor for?
Answer: Increasing heart rate, falling blood pressure, and increased wound drainage
Early hemorrhage signs include tachycardia, hypotension, and increasing wound drainage, all of which require immediate notification of the surgical team.
How does post-operative atelectasis typically present in the PACU?
Answer: Decreased breath sounds, reduced oxygen saturation, and possible fever
Post-operative atelectasis presents with decreased or absent breath sounds in affected lung areas, reduced oxygen saturation, and possible fever from lung collapse.
Which intervention is most effective in preventing post-operative atelectasis in PACU patients?
Answer: Incentive spirometry and deep breathing exercises
Incentive spirometry and deep breathing exercises promote alveolar expansion and are the most effective interventions for preventing post-operative atelectasis.
What is malignant hyperthermia (MH) and why is it considered a critical PACU emergency?
Answer: A potentially fatal hypermetabolic reaction to certain anesthetic agents characterized by hyperthermia, muscle rigidity, and acidosis
Malignant hyperthermia is a life-threatening pharmacogenetic disorder triggered by volatile anesthetics and succinylcholine, causing uncontrolled skeletal muscle metabolism.
What is the first-line specific treatment for malignant hyperthermia?
Answer: Dantrolene sodium administration combined with aggressive cooling and supportive care
Dantrolene sodium is the specific antidote for malignant hyperthermia and must be given promptly along with aggressive cooling and supportive treatment.
A patient develops hypotension 30 minutes after surgery. What is the PACU nurse's priority action?
Answer: Assess for the underlying cause, notify the physician, and initiate appropriate interventions based on findings
Post-operative hypotension requires prompt systematic assessment to identify the underlying cause before appropriate targeted treatment can be initiated, with timely physician notification.
