You can give nitroglycerin to a patient if the systolic blood pressure is at or above which value?

• A. Less than 100 mmHg
• B. ≥ 80 mmHg
• C. ≥ 100 mmHg
• D. ≥ 120 mmHg

Answer: (C)

Nitroglycerin is given to relieve chest pain by dilating veins, which lowers preload and reduces myocardial oxygen demand. It can also cause some arterial dilation and a drop in blood pressure. Because of that, you want to ensure there’s enough perfusion pressure left after the drug’s effects. A systolic blood pressure of 100 mmHg or higher provides a safety margin, so nitroglycerin can be used if there are no other contraindications. If the systolic pressure is below 100 mmHg, giving nitro risks significant hypotension that can compromise organ perfusion. After administration, monitor blood pressure and reassess, using the medication again only if the protocol allows and the patient remains within an acceptable pressure range.
