A patient in the PACU becomes agitated, tachycardic, and diaphoretic 20 minutes after receiving succinylcholine. Temperature is rising rapidly. What complication should the nurse suspect?
Answer: Malignant hyperthermia
Malignant hyperthermia is a life-threatening hypermetabolic crisis triggered by volatile anesthetics or succinylcholine, characterized by rapid temperature rise, rigidity, and tachycardia.
What is the first-line treatment for malignant hyperthermia?
Answer: Dantrolene sodium IV
Dantrolene sodium is the specific antidote for malignant hyperthermia; it inhibits calcium release from the sarcoplasmic reticulum to stop muscle hypermetabolism.
A patient emerges from general anesthesia with stridor and increased work of breathing. Which intervention is the priority?
Answer: Apply jaw thrust and call for anesthesia provider immediately
Stridor post-extubation indicates partial airway obstruction; a jaw thrust opens the airway while immediately summoning anesthesia support for potential reintubation.
A patient develops hypotension (BP 80/50) in the PACU after spinal anesthesia. Which intervention is most appropriate as the initial response?
Answer: Position the patient in Trendelenburg and administer IV fluid bolus as ordered
Spinal anesthesia causes sympathetic blockade leading to vasodilation; Trendelenburg positioning and IV fluid bolus are first-line treatments to restore preload and blood pressure.
Which assessment finding is an early sign of postoperative pulmonary embolism (PE) in a PACU patient?
Answer: Sudden onset tachycardia, dyspnea, and decreased SpO2
Sudden tachycardia, dyspnea, and SpO2 drop are early warning signs of PE caused by obstruction of pulmonary blood flow.
A patient becomes unresponsive with no palpable pulse in the PACU. What is the nurse's immediate priority action?
Answer: Activate the emergency response system and begin CPR
In a pulseless patient, immediate activation of the emergency response system and initiation of CPR are the highest priorities per ACLS guidelines.
