Evolve Cardiovascular Practice Test

Question: 1 / 400

What should a nurse consider as a possible cause of tachycardia related to lifestyle factors?

Dietary fiber increase

Stress management

Caffeine

Caffeine is well-known for its ability to stimulate the central nervous system, which can lead to increased heart rate or tachycardia. When consumed, caffeine blocks the action of adenosine, a neurotransmitter that promotes relaxation and sleepiness, thus resulting in heightened alertness and potential elevation of heart rate.

This stimulatory effect can be particularly pronounced in individuals who are sensitive to caffeine or who consume it in excess, making it a significant lifestyle factor to consider when evaluating causes of tachycardia. By recognizing caffeine consumption as a possible contributing factor, healthcare professionals can provide guidance to patients on managing their intake, which may help in reducing episodes of elevated heart rate.
