A client with an elevated cardiac index has received diuretic medication as prescribed. The nurse realizes that this medication will affect which cardiac parameter?
1. Afterload
2. Contractility
3. Preload
4. Stroke volume
3
Preload is characterized by the amount of cardiac muscle fiber stretch preceding each contraction. Preload will decrease with the use of diuretics. Contractility is the force of ventricular contraction. Afterload is the pressure and forces opposing ventricular contraction. The stroke volume is the amount of blood pumped by the left ventricle in one contraction. Diuretics do not specifically impact contractility, afterload, or stroke volume.
