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.

Explanation
Rationale:

C. Male pattern baldness is treated with other medications, such as finasteride, rather than terazosin.
D. Terazosin is also indicated for benign prostatic hypertrophy (BPH), as it helps alleviate urinary symptoms associated with this condition by relaxing the smooth muscles in the prostate and bladder neck.
E. Terazosin is not indicated for erectile dysfunction; it is primarily used for hypertension and BPH.
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.
