A nurse is caring for a client in the post-anesthesia unit who is experiencing malignant hyperthermia. Which of the following prescriptions should the nurse anticipate administering?
Correct answer
D
Rationale
The correct answer is D: Dantrolene. Malignant hyperthermia is a potentially life-threatening condition triggered by certain anesthetics. Dantrolene is the specific antidote for malignant hyperthermia as it works to inhibit calcium release from the sarcoplasmic reticulum, preventing muscle contraction and reducing body temperature. Verapamil (A) is a calcium channel blocker and not indicated for malignant hyperthermia. Naloxone (B) is an opioid antagonist used for opioid overdose, not for malignant hyperthermia. Cefazolin (C) is an antibiotic used for infection, not for malignant hyperthermia. Therefore, the correct choice is Dantrolene (D) for treating malignant hyperthermia.
