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 B
Explanation
Rationale:
A. A decrease in the amount of gastric acid production: Alosetron is not used to decrease gastric acid production. This effect is more associated with medications such as proton pump inhibitors or H2 blockers.
B. A decrease in the frequency of defecation: Alosetron is used to treat irritable bowel syndrome with diarrhea (IBS-D) by reducing bowel movement frequency and improving stool consistency.
C. An increase in gastric motility: Alosetron works by decreasing intestinal motility, which helps reduce diarrhea, not by increasing it.
D. An increase in the absorption of water into the intestine: Alosetron does not specifically increase water absorption into the intestine. Its primary effect is slowing intestinal transit to reduce diarrhea.
Correct Answer is B
Explanation
Rationale:
A. Nitrates: Nitrates are primarily used to manage angina or heart conditions and are unrelated to acetazolamide or its potential for allergic reactions.
B. Sulfa-based medications: Acetazolamide is a carbonic anhydrase inhibitor that contains sulfonamide groups. Clients with a sulfa allergy may experience a cross-sensitivity reaction, so it's important to confirm any history of sulfa allergies before administration.
C. Mostly cloudy: This option does not relate to any medication classification and is incorrect.
D. Antilipemic agents: Antilipemics are used to lower cholesterol and are not related to acetazolamide or its potential for allergic reactions.
E. Proton pump inhibitors: Proton pump inhibitors are used to reduce stomach acid and do not have a known cross-sensitivity with acetazolamide.
