Nitroglycerin is indicated for which condition?

Nitroglycerin is indicated for which condition?

• A. Chest pain of cardiac origin
• B. Hypertension
• C. Pulmonary edema
• D. Arrhythmia

Answer: (A)

Nitroglycerin relieves chest pain from cardiac ischemia by dilating veins, which lowers preload and reduces the heart’s oxygen demand. This makes it most appropriate for chest pain of suspected cardiac origin, such as angina or a possible heart attack. It’s not a treatment for hypertension, since it can drop blood pressure and isn’t used to address high blood pressure in this context. It isn’t the primary choice for arrhythmias, and while it can be used in some heart-failure situations to reduce preload, that’s not its main EMS indication.
