This module provides essential knowledge of cardiac physiology critical for nursing practice. Students will explore the basic structure and function of the heart, the mechanisms that regulate cardiac rhythm, and the components of a normal cardiac cycle. The module emphasizes key cardiac parameters including stroke volume and cardiac output, the electrical conduction system of the heart, and the interpretation of heart sounds. Students will examine electrocardiogram basics and learn to recognize normal cardiac function. The module also addresses common cardiovascular disorders and their clinical management, preparing students to identify significant changes in patient status such as cardiac arrhythmias, blood pressure variations, perfusion changes, and altered urine output. Through this exploration, learners will develop the cardiovascular knowledge necessary to monitor patients effectively, recognize early warning signs of cardiac compromise, and respond appropriately during cardiac emergencies and resuscitation efforts.
