What is a potential sign that nitroglycerin is still effective for a patient?

• A. Experiencing dizziness
• B. Feeling a tingling sensation under the tongue
• C. Color change of the tablet
• D. Immediate relief of chest pain

Answer: (B)

Feeling a tingling sensation under the tongue is an important indicator that nitroglycerin is still effective for a patient. When administered sublingually, nitroglycerin dissolves and is absorbed quickly into the bloodstream, and the tingling sensation is a common physiological response. This reaction suggests the medication is being absorbed properly and is likely to exert its vasodilatory effects, which help relieve anginal symptoms by increasing blood flow to the heart. It's important to recognize that while other signs or symptoms might occur in relation to medication effectiveness or patient response, they might not be as reliable as the tingling sensation. Dizziness can occur due to drops in blood pressure, color changes in the tablet indicate possible degradation and loss of potency, and immediate relief of chest pain can vary significantly from patient to patient, depending on the severity of their condition and individual response to the drug. Thus, the tingling sensation under the tongue serves as a more dependable indicator of the medication's effectiveness.
