The Correct Answer is D

Choice B rationale
Calcitonin is used to treat conditions like osteoporosis and hypercalcemia, not adrenal insufficiency.
Choice C rationale
Buspirone is an anxiolytic used to treat anxiety disorders and is not used for adrenal insufficiency.

Correct Answer is D
Explanation
Choice A rationale
Immediate-release exenatide pens should be discarded 30 days after the first use, not two months. This ensures the medication remains effective and free from contamination.
Choice B rationale
Exenatide is administered subcutaneously, not intramuscularly. The preferred injection sites are the abdomen, thigh, or upper arm.
Choice C rationale
Open exenatide pens should be stored at room temperature, but this is not the most critical aspect of patient education. Proper storage ensures the medication’s stability and effectiveness.
Choice D rationale
Immediate-release exenatide should be taken one hour before morning and evening meals to optimize its glucose-lowering effects by enhancing insulin secretion in response to meals.
Correct Answer is B
Explanation
Choice A rationale
Repeating up to four doses until pain is relieved is incorrect. The correct instruction is to take one tablet at the onset of pain and repeat every 5 minutes if needed, up to a maximum of three tablets in 15 minutes.
Choice B rationale
Storing unused tablets at room temperature is correct. Nitroglycerin tablets should be stored in their original container at room temperature, away from moisture and heat.
Choice C rationale
Taking two tablets at the onset of pain is incorrect. The correct instruction is to take one tablet at the onset of pain and repeat every 5 minutes if needed, up to a maximum of three tablets in 15 minutes.
Choice D rationale
Taking the medication two hours prior to exercise is incorrect. Nitroglycerin should be taken 5 to 10 minutes before an activity that may cause chest pain.
