Correct Answer: C

Rationale: When a pediatric client is taking propranolol, the nurse should instruct the parents to report signs of overdose, including bradycardia. Propranolol is a beta-blocker that can lead to dangerously slow heart rate as a sign of overdose. While increased respiratory rate, seizures, and irritability may occur in some cases, bradycardia is the most critical symptom indicating an overdose of this medication.

Correct Answer: C

Rationale: The most crucial nursing assessment in determining whether therapy should be initiated for an asymptomatic HIV-infected client with a CD4 cell count of 500 is the client's willingness to comply with complex drug schedules. Adherence to antiretroviral therapy is essential for its effectiveness. Assessing the client's willingness and ability to comply with the complex medication regimen is crucial to ensure successful treatment and prevent drug resistance. Choices A, B, and D, although important in the overall care of the client, are not as crucial as assessing the client's willingness to adhere to the prescribed drug regimen.

Correct Answer: B

Rationale: The correct answer is B: Toast with jelly. Tetracycline can cause gastrointestinal upset when taken with dairy products. Yogurt with fruit (Choice A) contains dairy, which can worsen the gastrointestinal upset. Crackers with peanut butter (Choice C) and oatmeal with raisins (Choice D) are also not the best choices as they may not be gentle enough on the stomach. Toast with jelly is a simple snack that does not contain dairy and is less likely to exacerbate the gastrointestinal upset.

Correct Answer: C

Rationale: Blood glucose monitoring is crucial for managing diabetes effectively. By monitoring blood sugar levels, individuals can understand how their lifestyle choices, medications, and diet affect their glucose levels. This information helps in making necessary adjustments to control blood sugar levels and prevent complications. While maintaining a low-sugar diet, foot care, and daily exercise are all important aspects of managing diabetes, blood glucose monitoring takes precedence as it provides real-time data for informed decision-making.

Correct Answer: A

Rationale: The correct answer is A: 'Take the medication with a full glass of water.' It is crucial for the nurse to teach the client to take ciprofloxacin with a full glass of water to prevent crystalluria, a potential side effect of the medication. Choice B is incorrect because ciprofloxacin does not require avoiding direct sunlight. Choice C is incorrect as taking the medication with meals is not necessary to prevent nausea. Choice D is incorrect as dizziness is not a common reason to discontinue ciprofloxacin.
