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","D","E"]
Explanation
Rationale:
A. Blurred vision is a common side effect of anticholinergic medications due to their effect on the eye muscles and pupil dilation.
B. Polyuria is not typically associated with anticholinergic medications; these medications may actually lead to urinary retention.
C. A productive cough is not an expected adverse effect of anticholinergic medications; instead, they may cause dry mucous membranes and a dry cough.
D. Tachycardia can occur as anticholinergic medications block the effects of acetylcholine on the heart, leading to increased heart rate.
E. Constipation is a well-known side effect of anticholinergic medications because they reduce gastrointestinal motility.
Correct Answer is C
Explanation
Rationale:
A. Monitoring alanine aminotransferase is important for liver function, but it is not the priority for a client on captopril.
B. Thyroid-stimulating hormone is not directly impacted by captopril and is not the priority lab value to monitor in this context.
C. Potassium is the priority laboratory value to monitor because captopril, an ACE inhibitor, can lead to hyperkalemia (elevated potassium levels), which can cause serious cardiac complications.
D. While magnesium levels are important to monitor, they are not specifically related to captopril therapy as potassium levels are.
