Which adverse effect might a nurse observe in a client prescribed nitroglycerin for angina?

Nitroglycerin is a nitrate medication commonly used to treat angina pectoris by dilating blood vessels and improving blood flow to the heart muscle. One of the most notable adverse effects of nitroglycerin is hypotension, which occurs because the medication causes vasodilation. This can lead to a decrease in blood pressure, especially when the patient stands up or exerts themselves, which may result in dizziness or fainting. It is essential for the nurse to monitor the patient’s blood pressure closely after administering nitroglycerin to prevent complications associated with lowered blood pressure.

While renal insufficiency, sedation, and hypokalemia may occur with various medications or health conditions, they are not common adverse effects directly associated with nitroglycerin. Monitoring for hypotension is crucial for ensuring patient safety when using this medication.
