Which possible adverse effect of nitroglycerin should a nurse mention to a client?

• A. Constipation
• B. Dizziness
• C. Fever
• D. Flushing

Answer: (B)

Dizziness is a commonly reported adverse effect of nitroglycerin due to its vasodilatory properties. When nitroglycerin is administered, it causes blood vessels to relax and widen, leading to a decrease in blood pressure. This sudden change can result in reduced cerebral perfusion, which can manifest as dizziness or lightheadedness, especially when a client stands up quickly or changes positions (orthostatic hypotension). Patients should be advised to rise slowly and to be aware of this potential effect, especially during the initiation of therapy or dose adjustments. Other options like constipation, fever, and flushing are less commonly associated with nitroglycerin. While flushing can occur due to vasodilation, it is not as significant a concern as dizziness, which poses a more immediate risk of falls or injury due to sudden changes in balance and perception. Therefore, emphasizing dizziness helps ensure client safety and promotes awareness of how they might respond to the medication.
