Correct Answer: D

Rationale: The correct answer is D. A nonstress test measures the fetal heart's response to movement, helping to assess fetal well-being. Choice A is incorrect as the duration of the test can vary, and it is not always precisely 30 minutes. Choice B is incorrect as drinking water is not necessary for a nonstress test. Choice C is incorrect as having a full bladder is not required for this test.

Correct Answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, elevated cortisol levels lead to increased gluconeogenesis, insulin resistance, and breakdown of proteins and fats, resulting in elevated blood glucose levels. This is known as hyperglycemia. The other options, including serum calcium level (choice B), lymphocyte count (choice C), and serum potassium level (choice D), are not typically affected by Cushing's disease. Therefore, they are incorrect choices.

Correct Answer: D

Rationale: Clear breath sounds are an essential indicator of effective pneumonia treatment as they suggest resolution of the lung infection. A normal respiratory rate (A) indicates adequate breathing but does not directly reflect the effectiveness of pneumonia treatment. An elevated white blood cell count (B) is a sign of infection and may not decrease immediately with treatment. While maintaining an SpO2 of 95% (C) is crucial for oxygenation, it may not directly indicate the effectiveness of pneumonia treatment.

Correct Answer: D

Rationale: A serum creatinine level of 3.0 mg/dL indicates impaired kidney function, which is a concern when prescribing spironolactone as it can further affect renal function. Elevated serum creatinine levels may suggest decreased renal clearance of spironolactone, leading to potential toxicity. Potassium, calcium, and magnesium levels are within normal ranges and not directly related to spironolactone therapy. Therefore, the nurse should report the elevated serum creatinine level to the provider for further evaluation and possible dosage adjustment.

Correct Answer: D

Rationale: The correct answer is D because it provides the medication (Metoprolol), dosage (5 mg), route of administration (IV), and timing (now), making it a complete prescription. Choices A, B, and C lack either the route of administration or timing, making them incomplete prescriptions. For choice A, it lacks the route of administration, and for choices B and C, they lack the timing of administration.
