To improve ventricular contractility in a child with a ventricular septal defect, the nurse would expect to administer:
A) a diuretic.
B) a cardiac glycoside.
C) an ACE inhibitor.
D) an aldosterone receptor blocker.
B) a cardiac glycoside.
Explanation: A) Medical management of the VSD is aimed at reducing afterload. Afterload is the resistance the heart must overcome to eject the volume of blood from the ventricle and is expressed as total peripheral resistance. Medical management includes a diuretic to help decrease pulmonary volume, an afterload reducing agent such as an ACE inhibitor or aldosterone receptor blocker, and possibly digoxin, a cardiac glycoside agent that improves contractility of the ventricle.
