Question

1. with _______ , blood flows backward through an incomplete pulmonic valve from the pulmonary artery to the right ventricle.

pulmonic regurgitation
mitral regurgitation
tricuspid regurgitation
aortic regurgitation

1. which of the following is not a congenital heart defect?

atrial septal defect
cerebral vascular accident
tetralogy of fallot
ventricular septal defect

Explanation:

Question 37

Pulmonic regurgitation involves blood flowing backward through the pulmonic valve (from pulmonary artery to right ventricle) due to valve incompetence. Mitral regurgitation is about the mitral valve (left side), tricuspid about tricuspid valve (right atrium - ventricle), and aortic about aortic valve (left ventricle - aorta). So the correct option relates to pulmonic valve.

Congenital heart defects are present at birth. Atrial septal defect, tetralogy of Fallot, and ventricular septal defect are congenital. Cerebral vascular accident (stroke) is a vascular event in the brain, not a congenital heart defect.

Answer:

A. pulmonic regurgitation
