For moderate to severe signs and symptoms of CHF/Pulmonary edema with a SBP greater than 200, what is the nitro dose?

• A. 0.8 mg SL
• B. 0.4 mg SL
• C. 1.2 mg SL
• D. 2.0 mg SL

Answer: (C)

Sublingual nitroglycerin is given in small, repeatable doses to reduce preload and afterload in CHF with pulmonary edema. Each tablet is 0.4 mg, and you can administer one tablet every 5 minutes up to three times if the patient remains hypertensive and there are no contraindications. That means the total possible dose is 1.2 mg. In a patient with a systolic BP over 200, you’re allowed to continue with additional 0.4 mg doses to reach that total, provided there’s still no hypotension or adverse effects. Therefore, the best answer reflects the maximum cumulative dose achievable with the standard SL dosing protocol: 1.2 mg.
