Nokea
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
Correct Answer: A
Rationale: 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.
