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 A
Explanation
Rationale:
A. Albuterol: This is a bronchodilator that can cause side effects such as increased heart rate and chest pain due to its stimulant effect on the cardiovascular system.
B. Furosemide: This diuretic is unlikely to cause chest pain directly; however, it may lead to electrolyte imbalances that can indirectly affect cardiac function.
C. Digoxin: While digoxin has several potential side effects, chest pain is not commonly recognized as a direct adverse effect of this medication.
D. Atenolol: This medication is a beta-blocker used to manage hypertension and is unlikely to cause chest pain; rather, it may help alleviate angina symptoms.
Correct Answer is A, B, C, D, E
Explanation
Rationale:
- Administering albuterol first is crucial because it is a bronchodilator that will help open the airways before administering the anti-inflammatory fluticasone.
- The client should rest for 1 minute between puffs of albuterol to allow for the medication to take effect.
- After taking the second puff of albuterol, a longer rest of 5 minutes allows the client to experience the full effects of the bronchodilator.
- Finally, administering fluticasone afterward will help reduce inflammation in the airways, maximizing the benefit of both medications.
