Where should Nitro-Paste be applied and in what amount?

• A. 2" to the back
• B. 3" to the upper chest
• C. 1" to the anterior upper chest
• D. 1" to the forearm

Answer: (C)

Nitro-Paste is a topical nitroglycerin used to cause vasodilation and relieve chest pain by delivering a steady, predictable amount of medication through the skin. The most reliable site and amount is a one-inch strip placed on the anterior upper chest. This area provides good, steady absorption through well-perfused skin and stays in place more reliably, giving a consistent dose. Using a longer strip would deliver more drug and raise the risk of significant blood pressure drops, while other locations like the forearm are less effective for predictable absorption. So, a one-inch strip on the anterior upper chest is the best practice.
