Pediatric Nursing Cardiovascular Disorders Questions
Question 1 of 5
What does the surgical closure of the ductus arteriosus do?
Correct Answer: D
Rationale: The ductus arteriosus allows blood to flow from the higher-pressure aorta to the lower-pressure pulmonary artery, causing a right-to-left shunt. If this is surgically closed, no additional oxygenated blood (from the aorta) will return to the lungs through the pulmonary artery. The aorta carries oxygenated blood to the systemic circulation. Because of the higher pressure in the aorta, blood is shunted into the pulmonary artery and the pulmonary circulation. Edema in the legs and feet is usually a sign of heart failure. This repair would not directly affect the edema. Increasing the oxygenation of blood would not interfere with the return of oxygenated blood to the lungs.

Question 3 of 5
The nurse is caring for a child with persistent hypoxia secondary to a cardiac defect. The nurse recognizes that a risk exists of cerebrovascular accidents (strokes). Which is an important objective to decrease this risk?
Correct Answer: B

Question 4 of 5
The nurse is caring for a child after heart surgery. What should the nurse do if evidence of cardiac tamponade is found?
Correct Answer: C
Rationale: If evidence is noted of cardiac tamponade, which is blood or fluid in the pericardial space constricting the heart, the physician is notified immediately of this life-threatening complication. Increasing analgesia may be done before the physician drains the fluid, but the physician must be notified. Warming blankets are not indicated at this time. Encouraging the child to cough, turn, and breathe deeply should be deferred till after the evaluation by the physician.
