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. "Remove the patch for two to four hours daily.": This is incorrect because transdermal nitroglycerin patches should be worn continuously for 24 hours, with a scheduled time to remove them (usually overnight) to prevent tolerance.
B. "Apply a new patch each day after waking up.": This instruction is correct; clients should apply a new patch daily to ensure continuous therapeutic effects while also allowing a break to reduce tolerance.
C. "Cover the patch with plastic wrap.": This is incorrect; covering the patch with plastic wrap can alter the absorption of the medication and is not necessary.
D. "Replace the existing patch with a new patch as soon as anginal pain begins.": This is incorrect; clients should not replace the patch immediately for angina. Instead, they should use sublingual nitroglycerin for immediate relief and follow the prescribed patch schedule.
Correct Answer is A
Explanation
Rationale:
A. Requesting a serum trough level blood draw for 60 minutes after the completion of the infusion is appropriate for monitoring the therapeutic levels of vancomycin and ensuring it is within the desired range to prevent toxicity.
B. Changing the infusion site after each dose administration is not necessary unless there is an issue such as infiltration or phlebitis; typically, the site can be used for multiple doses if it remains patent and functional.
C. Contacting the provider for prescription clarification is not needed unless there are specific concerns about the medication or the administration protocol; in this case, the order is clear and standard.
D. Requesting a serum peak level to be drawn 30 minutes prior to infusion is incorrect, as the peak level should be drawn 30 minutes after the completion of the infusion, not before the next dose.
