Correct Answer: B

Rationale: The correct answer is B. Certain combinations of food and drugs can indeed lead to adverse reactions. It is important to be cautious with the simultaneous intake of food and drugs as interactions between them can affect their efficacy and safety. Choices A, C, and D are incorrect because they do not accurately reflect the potential risks associated with the combination of food and drugs.

Correct Answer: A

Rationale: The correct answer is to check the thyroid hormone assay. Long-term lithium use can result in thyroid dysfunction, making it crucial to monitor the client's thyroid function regularly to detect any abnormalities early and prevent potential complications. Liver function tests (choice B) are not specifically associated with lithium therapy. Erythrocyte sedimentation rate (choice C) is a nonspecific test for inflammation and not directly related to lithium therapy. Brain natriuretic peptide (choice D) is a test used to diagnose heart failure and is not relevant to monitoring lithium therapy.

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: D

Rationale: A creatinine level of 1.0 mg/dL should be reported to the provider immediately. While a lithium level of 1.0 mEq/L falls within the therapeutic range, a creatinine level of 1.0 mg/dL could suggest early signs of kidney dysfunction, especially concerning in a client on long-term lithium therapy. It is crucial to monitor kidney function closely because lithium can be nephrotoxic over time. Elevated creatinine levels may indicate impaired kidney function and should prompt immediate reporting to the healthcare provider. Potassium and sodium levels within normal range are not immediate concerns when compared to potential kidney issues.

Correct Answer: B

Rationale: The correct answer is B. Certain combinations of food and drugs can indeed lead to adverse reactions. It is important to be cautious with the simultaneous intake of food and drugs as interactions between them can affect their efficacy and safety. Choices A, C, and D are incorrect because they do not accurately reflect the potential risks associated with the combination of food and drugs.
