D) evaluating the effectiveness of cardiac contractions.

Question

Quizplus · Accepted Answer

An ECG monitor is specifically used to evaluate the heart's electrical conduction system for abnormalities, such as arrhythmias or heart blockages. It does not provide information about cardiac output or stroke volume, which require other forms of monitoring or testing. While changes on an ECG may suggest problems with cardiac contractions or effectiveness, this is not the primary purpose of the monitor.
