Question

Premature opening of the pulmonary valve may be seen in:

a) cardiac tamponade
b) Pulmonary insufficiency
c) constrictive pericarditis
d) acute severe pulmonary hypertension

Answer 1

Premature opening of the pulmonary valve may be seen in acute severe pulmonary hypertension, a condition characterized by high blood pressure in the pulmonary arteries.

Step-by-step explanation:

The premature opening of the pulmonary valve may be seen in acute severe pulmonary hypertension. Acute severe pulmonary hypertension is a condition characterized by high blood pressure in the pulmonary arteries, which puts strain on the right ventricle and can cause the pulmonary valve to open prematurely. This can lead to inadequate blood flow and oxygenation in the lungs. In this condition, the pulmonary valve fails to close properly, allowing blood to flow back into the right ventricle during diastole.
