After nitroglycerin administration, which parameter is most important to monitor for safety?

• A. Temperature
• B. Respiratory rate
• C. Blood pressure
• D. Oxygen saturation

Answer: (C)

Nitroglycerin works by dilating blood vessels, especially veins, which reduces the amount of blood returning to the heart and lowers blood pressure. Because the main safety concern with this medication is a drop in blood pressure (hypotension), monitoring blood pressure after administration is the most important parameter. Detecting a significant BP drop early allows you to stop or withhold further dosing, position the patient safely, and treat the hypotension as needed. Oxygen saturation and respiratory rate are important for overall patient status, but they don’t directly reveal the risk of nitroglycerin-induced hypotension. Temperature is not a primary concern with this medication.
