Pharmacology Proctored ATI Practice Exam

What instruction should the nurse give to a client with angina pectoris about using SL nitroglycerin tablets?

1. Take one tablet at the first indication of chest pain

2. Wait until the pain is severe before taking the tablet

3. Take two tablets before any physical activity

4. Dissolve the tablet in water before ingestion

The correct answer is: Take one tablet at the first indication of chest pain

When experiencing chest pain, it is important for the client with angina pectoris to take one SL nitroglycerin tablet at the first indication of pain. This is because the medication works quickly and can help alleviate the pain before it becomes more severe. It is not recommended to wait until the pain is severe, as this may delay the relief and also put the client at risk for a more serious cardiac event. Taking two tablets at once or dissolving the tablets in water before ingestion are also not recommended as they can cause a faster and potentially dangerous drop in blood pressure. Therefore, option A is the most appropriate instruction for the client to follow.
