How often can nitro be administered for a patient with CHF?

• A. 2 min
• B. 3 min
• C. 5 min
• D. 4 min

Answer: (C)

Administering nitroglycerin in CHF is guided by giving the drug and then waiting a set period to see how the patient responds before repeating. Nitroglycerin works quickly to reduce preload and relieve pulmonary congestion, so you want to watch for improvement in breathing and blood pressure after each dose. A five-minute interval lets the drug take effect and provides time to reassess hemodynamics safely. If the patient remains hypertensive or symptomatic after reassessment, you can give another dose at that five-minute mark, typically up to three doses total, as long as blood pressure stays above a safe level and there are no contraindications. Shorter intervals don’t give enough time to gauge response and can increase the risk of hypotension or unnecessary dosing.
