A nurse is reinforcing teaching with a client who has chronic stable angina and a new prescription for sublingual nitroglycerin. Which of the following instructions should the nurse include in the teaching?
"Take the medication with a sip of water."
"Take up to four tablets in 15 minutes."
"Chew each tablet completely before swallowing.
"Take one tablet before a strenuous activity."
The Correct Answer is D
A. Nitroglycerin is meant to be absorbed under the tongue, and water is not necessary.
B. The client should take up to three doses 5 minutes apart and seek emergency medical attention if pain persists. The maximum number of tablets that should be taken in 15 minutes is 3 and not 4 since this could cause severe hypotension and headache.
C. Nitroglycerin tablets are meant to be dissolved under the tongue, not chewed or swallowed.
D. Sublingual nitroglycerin is used to prevent angina attacks by dilating the coronary arteries and increasing blood flow to the heart. The client should take one tablet for 5 to 10 minutes before engaging in an activity that might trigger angina, such as exercise, stress, or cold exposure.

Correct Answer is D
Explanation
The correct answer is D.
A. Dizziness: Dizziness is a common side effect of diphenhydramine, often due to its sedative properties. It is not considered an idiosyncratic reaction because it is a predictable and expected response to the medication.
B. Nausea: Nausea can occur with diphenhydramine use, especially if taken on an empty stomach or in higher doses. This is also a known side effect and not an idiosyncratic reaction.
C. Dry mouth: Dry mouth is another common side effect of diphenhydramine, resulting from its anticholinergic effects. This reaction is predictable and not idiosyncratic.
D. Agitation: Agitation is an idiosyncratic reaction to diphenhydramine. While the drug is typically sedating, some individuals may experience paradoxical excitation, leading to symptoms like agitation. This unpredictable response is what makes it idiosyncratic.
