Answer to Question 1

ANS: C
PS is a narrowing or stricture of the pulmonary valve causing resistance to blood flow from the right ventricle to the pulmonary artery. PS is not associated with an abnormality of the pulmonary tree, the pulmonary artery, or the vein.

Answer to Question 2

ANS: D
The patient is experiencing neurogenic shock in which blood volume has not changed, but SVR decreases drastically so that the amount of space containing the blood has increased, leading to hypotension. In this type of shock, blood loss has not occurred. In this type of shock, fluid loss has not occurred. Vasodilation due to infection would be septic shock; the type of shock de-scribed in the patient is due to loss of sympathetic stimulation.
