A nurse is preparing a client for a scheduled adenosine stress test. Which statement made by the client indicates a need for further education?

The answer is Option C ("My family is bringing me a cup of coffee to drink before the test.")

Explanation:

Adenosine stress test:

Adenosine stress test also referred to as myocardial perfusion imaging is a non-invasive imaging test which uses radioactive material called tracers to show areas of the heart muscle that aren't getting enough blood flow. Pharmaceutical stress is used to increase blood flow to the heart muscle. The administration of adenosine acts on the cardiovascular system and to promote vasodilatation.

Some of the side effects of Adenosine are: flushing, dizziness, head pressure, nausea, chest pain.

There is a need to abstein from caffeine and other methylxanthines before the adenosine stress test for at least 24 hours before testing. caffeine intake may interfere with adenosine-induced coronary hyperemia and myocardial perfusion imaging. Coffee drink contains caffeine which raises blood pressure and heart rate. It also increases the risk of developing irregular heartbeat.
