A nurse in the PACU is caring for a client who has received general anesthesia and has manifestations of malignant hyperthermia. Which of the following medications should the nurse expect to administer?
Diazepam
Dantrolene
Cyclobenzaprine
Metaxalone
The Correct Answer is B
Rationale:
A. Diazepam is a benzodiazepine used for anxiety and sedation but is not effective for treating malignant hyperthermia.
B. Dantrolene is the specific antidote for malignant hyperthermia, and the nurse should expect to administer it to help reduce the severe muscle contractions and hypermetabolism associated with this condition.
C. Cyclobenzaprine is a muscle relaxant used for muscle spasms but is not indicated for malignant hyperthermia.
D. Metaxalone is also a muscle relaxant, but like cyclobenzaprine, it is not effective for managing malignant hyperthermia and would not be used in this situation.

Correct Answer is D
Explanation
Rationale:
A. This statement is incorrect because omeprazole is not an antibiotic and does not kill bacteria; it is a proton pump inhibitor (PPI) that reduces acid production.
B. This statement is incorrect; omeprazole does not neutralize stomach acid, but rather decreases its production.
C. This statement is also incorrect; omeprazole does not coat the stomach lining; it works by inhibiting the proton pumps in the stomach lining to reduce acid secretion.
D. This statement is correct; omeprazole reduces stomach acid production, which is beneficial for managing GERD symptoms.
Correct Answer is D
Explanation
Rationale:
A. Lactated Ringer's: This solution is isotonic and is typically used for fluid resuscitation, not for hypotonic treatment.
B. 0.9% sodium chloride: This is isotonic saline and does not qualify as a hypotonic solution.
C. 3% sodium chloride: This solution is hypertonic and used to treat severe hyponatremia, not hypotonic hydration.
D. 0.45% sodium chloride: This is the correct choice as it is a hypotonic solution that can help to hydrate cells by providing free water.
