Correct Answer: A

Rationale: Ciclosporin is extensively metabolized by CYP3A enzymes, making it susceptible to drug interactions with inhibitors or inducers of this pathway.

Correct Answer: A

Rationale: The correct instruction the nurse should give the patient who is experiencing constipation and dry mouth as side effects of amitriptyline (Elavil) is to increase fluid intake. Increasing fluid intake can help alleviate these side effects. Adequate hydration can help with constipation by softening stools and making bowel movements easier, and it can also help relieve dry mouth by promoting saliva production. It is a simple and effective measure that can be taken to manage these common side effects without the need to stop the medication or switch to a different antidepressant.

Correct Answer: C

Rationale: The most helpful test in determining the response to highly active antiretroviral therapy (HAART) in an HIV-positive client is a viral load test. A viral load test measures the amount of HIV in the blood by counting the number of copies of the virus present. Monitoring viral load levels over time provides vital information about how well the antiretroviral medications are working in suppressing the replication of the virus. A decrease in viral load indicates a positive response to the therapy, while an increase may suggest treatment failure or the development of drug resistance. Regular monitoring of viral load is a crucial aspect of managing HIV infection and assessing the effectiveness of antiretroviral therapy.

Correct Answer: A

Rationale: Diarrhea is one of the most debilitating side effects of chemotherapy because it can lead to severe dehydration, electrolyte imbalances, and malnutrition. Persistent diarrhea can significantly impact the patient's quality of life, causing fatigue, weakness, and discomfort. While alopecia, constipation, and pain are also common side effects, diarrhea poses a greater immediate risk to the patient's physical health and ability to continue treatment. Managing diarrhea is therefore a priority in chemotherapy care.
