What does the nurse explain that a ventricular septal defect will allow?
a. Blood to shunt left to right, causing increased pulmonary flow and no cyanosis
b. Blood to shunt right to left, causing decreased pulmonary flow and cyanosis
c. No shunting because of high pressure in the left ventricle
d. Increased pressure in the left atrium, impeding circulation of oxygenated blood in the circulating volume
ANS: A
Pulmonary blood flow is increased when a ventricular septal defect exists. The blood shifts from left to right because of the higher pressure in the left ventricle. This particular shift does not cause cyanosis.
