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 D
Explanation
Rationale:
A. Mostly cloudy: This option appears to be incorrectly stated. It does not pertain to a critical client assessment related to morphine administration.
B. Apical heart rate: Monitoring the heart rate is important, but respiratory depression is a more immediate and life-threatening concern with morphine administration, so it is not the first priority.
C. Blood pressure: Morphine can cause hypotension, but this is not as critical as respiratory depression, which must be assessed first in opioid administration.
D. Respiratory rate: The most critical assessment when administering morphine is the respiratory rate, as opioid medications like morphine can cause respiratory depression, which can be life-threatening if not addressed.
E. Level of consciousness: While important, changes in consciousness typically follow respiratory depression, so assessing the respiratory rate takes priority.
