Correct Answer: C

Rationale: The correct answer is to instruct the client to rotate the patch site each time they apply it. This practice helps prevent skin irritation and ensures the effectiveness of nitroglycerin transdermal patches. Applying the patch to the same site each time can lead to skin irritation and decreased patch efficacy. Choices A, B, and D are incorrect because applying the patch to the upper arm, removing it before showering, and placing it on the lower abdomen do not promote proper rotation of patch sites, which is essential for optimal outcomes.

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.

Correct Answer: C

Rationale: The correct instruction when taking alendronate is to remain upright for 30 minutes after administration. This helps prevent esophageal irritation, a known side effect of the medication.

Option D is incorrect as alendronate should be swallowed whole with a full glass of water and not chewed.

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.
