Question 1
The nurse is caring for a patient in the operating suite who is experiencing hypercarbia, tachypnea, tachycardia, premature ventricular contractions, and muscle rigidity. Which condition does the nurse suspect the patient is experiencing?
- A. Malignant hyperthermia
- B. Fluid imbalance
- C. Hemorrhage
- D. Hypoxia
Show answer and rationale
Correct answer: A — Malignant hyperthermia
The correct answer is A: Malignant hyperthermia. Hypercarbia, tachypnea, tachycardia, premature ventricular contractions, and muscle rigidity are characteristic signs of malignant hyperthermia, a rare but life-threatening reaction to certain anesthetics. This condition is triggered by an abnormal response to specific anesthetic agents, leading to increased muscle metabolism, hyperthermia, and potentially fatal complications. Prompt recognition and treatment, including discontinuation of triggering agents, administration of dantrolene, and supportive care, are crucial. B: Fluid imbalance is incorrect because the symptoms described are not typically associated with fluid imbalance. C: Hemorrhage is incorrect as it does not typically present with the combination of symptoms mentioned. D: Hypoxia is incorrect as it usually presents with different clinical manifestations such as cyanosis, confusion, and respiratory distress.
