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. Frequent sputum tests may be needed to monitor the effectiveness of isoniazid, particularly in assessing the resolution of tuberculosis infection.
B. Isoniazid is usually prescribed for a minimum of six months for tuberculosis treatment, not just a month. Thus, stopping after one month is incorrect.
C. Antacids containing aluminum should not be taken concurrently with isoniazid, as they can interfere with the absorption of the medication, reducing its effectiveness.
D. Constipation is not a common side effect of isoniazid. The more frequent side effects include peripheral neuropathy and liver toxicity, making this statement incorrect.
Correct Answer is A
Explanation
Rationale:
A. Increase fluids while taking the medication: Amitriptyline is a tricyclic antidepressant that can cause anticholinergic side effects such as dry mouth and constipation. Increasing fluid intake helps to mitigate these effects and prevent dehydration and constipation.
B. Expect an elevation in blood pressure with initial doses of the medication: Amitriptyline can cause orthostatic hypotension rather than elevated blood pressure. Clients should be informed about the risk of dizziness or fainting.
C. Stop the medication immediately if urine becomes orange in color: Orange urine is not a common side effect of amitriptyline. Clients should not stop the medication without consulting their provider.
D. Take the medication in the morning: Amitriptyline has sedative effects and is typically taken at night to help manage sleep disturbances and reduce daytime drowsiness.
