A nurse in a provider’s office is caring for a 20-year-old client who is at 12 weeks of gestation and requests an amniocentesis to determine the sex of the fetus.
Which of the following responses should the nurse make?

Choice A rationale
While assessing the client’s kidney function is important in general, it is not the best way to evaluate medication adherence. Kidney function can affect the metabolism and excretion of medications, but it does not directly indicate whether the client is taking their medication as prescribed.
Choice B rationale

Correct answer. Checking the client’s serum medication level is the most direct and reliable way to evaluate medication adherence. If the client is taking the medication as prescribed, the serum medication level should be within the therapeutic range.
Choice C rationale
Determining the client’s apical pulse rate can provide information about the client’s overall cardiovascular status and can indicate certain drug effects or side effects, but it does not directly measure medication adherence.
Choice D rationale
Asking the client if they are taking the medication as prescribed can provide useful information, but it relies on self-report, which may not be reliable. Some clients might forget doses or not take the medication exactly as prescribed.

Choice A rationale
Fresh citrus fruits are a good source of vitamin C, but they do not contain vitamin B125. Vitamin B12 is not naturally present in plant foods, so vegans need to get it from fortified foods or supplements.
Choice B rationale

Raw carrots are a good source of vitamins A and K, and dietary fiber, but they do not contain vitamin B125. Vegans need to get vitamin B12 from other sources.
Choice C rationale
Brown rice is a good source of B vitamins like B1 (thiamin) and B3 (niacin), but it does not contain vitamin B125. Vegans need to get vitamin B12 from other sources.
Choice D rationale
Fortified soy milk is a good source of vitamin B12 for vegans. Many brands of soy milk are fortified with vitamins, including B12, making them a good choice for vegans looking to increase their vitamin B12 intake.
