Question

The nurse's assignment includes an infant with pulmonic stenosis (ps). before asking questions about the child's condition, the rn reasons that the disorder would involve which of the following?

a. a single blood vessel arising from both ventricles
b. obstruction of blood from the right ventricle
c. obstruction of blood from the left ventricle
d. return of blood to the heart without entry into the left atrium

Answer 1

Pulmonic stenosis involves the obstruction of blood from the right ventricle, impeding blood flow to the pulmonary arteries and requiring the heart to work harder. The correct option is B.

Step-by-step explanation:

The nurse's assignment includes an infant with pulmonic stenosis (PS). Before asking questions about the child's condition, the RN correctly reasons that this disorder involves obstruction of blood from the right ventricle.

Pulmonic stenosis is characterized by a narrowing at the pulmonary valve or just below it, which impedes the flow of blood from the right ventricle to the pulmonary arteries. As a result, the heart must work harder to pump blood into the pulmonary circulation.

This condition does not relate to the other options given: a single blood vessel arising from both ventricles, obstruction of blood from the left ventricle, or return of blood to the heart without entry into the left atrium. The correct option is B.
