Question 10

An infant is experiencing dyspnea related to patent ductus arteriosus (PDA).What does the nurse understand regarding why dyspnea occurs?

A) Blood is circulated through the lungs again,causing pulmonary circulatory congestion.
B) Blood is shunted past the pulmonary circulation,causing pulmonary hypoxia.
C) Blood is shunted past cardiac arteries,causing myocardial hypoxia.
D) Blood is circulated through the ductus from the pulmonary artery to the aorta,bypassing the left side of the heart.

A) Coronary arteries
B) Heart muscle and the mitral valve
C) Aortic and pulmonic valves

A) Barium swallow
B) Chest x-ray
C) Electrocardiogram
D) Echocardiogram

Question 14

Through what does the infant born with hypoplastic left heart syndrome acquire oxygenated blood?

A) The patent ductus arteriosus
B) A ventricular septal defect
C) The closure of the foramen ovale

Question 15

How would the nurse caring for an infant with congestive heart failure (CHF)modify feeding techniques to adapt for the child's weakness and fatigue? (Select all that apply. )

A) Feeding more frequently with smaller feedings
B) Using a soft nipple with enlarged holes
C) Holding and cuddling the child during feeding
D) Substituting glucose water for formula
E) Offering high-caloric formula

Question 16

A father asks why his child with tetralogy of Fallot seems to favor a squatting position.What is the nurse's best response?

A) Squatting increases the return of venous blood back to the heart.
B) Squatting decreases arterial blood flow away from the heart.
C) Squatting is a common resting position when a child is tachycardic.
D) Squatting increases the workload of the heart.

Question 17

The nurse explained how to position an infant with tetralogy of Fallot if the infant suddenly becomes cyanotic.Which statement by the father leads the nurse to determine he understood the instructions?

A) "If the baby turns blue,I will hold him against my shoulder with his knees bent up toward his chest."
