A 10-year-old child with ADHD has been prescribed a stimulant medication. The parent reports that the child has been eating less since starting the medication. What is the most appropriate nursing intervention to address this side effect?

A. Increased risk of arrhythmias due to drug interactions: While both drugs affect cardiovascular function, the primary risk with concurrent use is not arrhythmias. Nitroglycerin and PDE-5 inhibitors mainly influence vascular tone, not cardiac electrical activity directly.
B. Potential for life-threatening hypotension due to excessive vasodilation: Both nitroglycerin and PDE-5 inhibitors are potent vasodilators. When used together, they can cause profound hypotension due to synergistic effects on the vascular system, which may lead to syncope, myocardial infarction, or even death.
C. Increased risk of severe headache due to overlapping side effects: Headache is a known side effect of both drugs due to vasodilation, but it is not the most dangerous interaction. While uncomfortable, headaches are not life-threatening compared to the risk of severe hypotension.
D. Decreased effectiveness of nitroglycerin in relieving angina: There is no evidence that PDE-5 inhibitors reduce the efficacy of nitroglycerin. The concern is not about reduced therapeutic benefit but rather the risk of severe, potentially fatal cardiovascular side effects.

A. Advise the parent to discontinue the medication immediately: Discontinuing the medication without consulting the healthcare provider is unsafe. Stimulants are effective in managing ADHD symptoms, and any adjustments should be made under medical supervision. Abrupt cessation may lead to a return or worsening of symptoms.
B. Encourage the parent to eliminate all snacks between meals to promote hunger at mealtimes: While reducing snacks may improve appetite, it can also result in missed opportunities for nutrient intake, especially when the child already has a reduced appetite due to the medication. This intervention is not the most appropriate or immediate.
C. Encourage the parent to increase the child's physical activity to stimulate appetite: Physical activity can naturally increase appetite over time, but it is not the most direct or effective strategy for managing stimulant-induced appetite suppression. This approach is more of a long-term supportive strategy.
D. Encourage the parent to make breakfast the most important meal of the day before administering the medication: Stimulant medications commonly reduce appetite, especially later in the day. Ensuring the child eats a nutritious breakfast before taking the medication helps maximize calorie and nutrient intake when appetite is highest. This is the most appropriate initial nursing intervention.
