A client has a new prescription for Trimethoprim-sulfamethoxazole. Which of the following information should the nurse include?

Correct Answer: C

Rationale: The correct answer is C: 'Take it with food.' Trimethoprim-sulfamethoxazole can cause gastrointestinal upset, and taking it with food helps reduce the risk of stomach irritation. It should not be taken on an empty stomach. Maintaining good hydration is important to prevent kidney-related side effects, so maintaining a fluid restriction, as in choice B, is not appropriate. Additionally, stopping the medication when manifestations subside, as in choice D, is incorrect as antibiotics should be taken for the full prescribed course to ensure eradication of the infection and to prevent antibiotic resistance.

Correct Answer: A

Rationale: NRTIs inhibit the enzyme reverse transcriptase, essential for HIV replication. By preventing this process, viral replication is hindered, ultimately reducing the viral load in the body. Option A correctly explains the mechanism of action of NRTIs in treating HIV infection. Choices B, C, and D describe mechanisms of action that do not align with how NRTIs work in HIV treatment. B is incorrect because NRTIs do not target protein synthesis within the HIV cell. C is incorrect as NRTIs do not affect the cell wall of the HIV virus. D is incorrect because NRTIs do not block HIV entry into cells.

Correct Answer: A

Rationale: The correct instruction is to take Efavirenz at bedtime to prevent drowsiness and manage central nervous system side effects like dizziness and vivid dreams. While it is important to take the medication at the same time daily for consistent blood levels, the emphasis should be on bedtime to minimize the impact of these side effects. Choices B and C suggesting taking the medication with milk or juice are incorrect and not relevant to optimizing Efavirenz therapy.

Correct Answer: A

Rationale: The correct answer is A: Ondansetron. Ondansetron is a commonly used antiemetic for managing nausea and vomiting in clients undergoing chemotherapy. It works by blocking serotonin to reduce these symptoms effectively. Metoclopramide (choice B) is another antiemetic but is more commonly used for gastric motility disorders. Promethazine (choice C) is an antihistamine with antiemetic properties, but ondansetron is often preferred for chemotherapy-induced nausea and vomiting due to its efficacy and fewer side effects. Lorazepam (choice D) is a benzodiazepine used for anxiety and insomnia, not typically for managing nausea and vomiting in this context.

Correct Answer: A

Rationale: The correct instruction that the nurse should include in the teaching for a client prescribed Cyclobenzaprine is to avoid driving or operating heavy machinery while taking this medication. Cyclobenzaprine can cause drowsiness, so it is important to advise clients to avoid activities that require alertness and coordination to prevent accidents or injuries. Choice B is incorrect because Cyclobenzaprine can be taken with or without food. Choice C is incorrect because Cyclobenzaprine is typically taken regularly as prescribed, not just when experiencing muscle pain. Choice D is incorrect because there is no specific need to increase potassium-rich foods while taking Cyclobenzaprine.
