A nurse is caring for an infant who has a congenital heart defect. Which of the following defects is associated with increased pulmonary blood flow?
Coarctation of the aorta
Patent ductus arteriosus
Tetralogy of Fallot
Tricuspid atresia
The Correct Answer is B
A patent ductus arteriosus (PDA) is a congenital heart defect associated with increased pulmonary blood flow. In normal fetal circulation, the ductus arteriosus allows blood to bypass the lungs since the baby receives oxygen from the mother's placenta. After birth, the ductus arteriosus should close, redirecting blood flow to the lungs for oxygenation. However, in some infants with PDA, the ductus arteriosus remains open, causing an abnormal connection between the aorta and the pulmonary artery. As a result, oxygenated blood from the aorta flows back into the pulmonary artery, increasing the workload on the lungs.
The other options are as follows:
A. Coarctation of the aorta - Coarctation of the aorta is a narrowing of the aorta, which obstructs blood flow and leads to increased blood pressure in the upper body and reduced blood flow to the lower body.
C. Tetralogy of Fallot - Tetralogy of Fallot is a combination of four heart defects that results in decreased pulmonary blood flow due to a ventricular septal defect (VSD), overriding aorta, pulmonary stenosis, and right ventricular hypertrophy.
D. Tricuspid atresia - Tricuspid atresia is a congenital heart defect where the tricuspid valve does not develop correctly, resulting in an absent or abnormal tricuspid valve. This defect prevents blood flow from the right atrium to the right ventricle and, therefore, reduces pulmonary blood flow.

Correct Answer is B
Explanation
Following a cardiac catheterization, the nurse should provide the parent with appropriate discharge instructions to ensure the child's proper recovery. The correct instruction to include is option B: "Give the child acetaminophen for discomfort."
Explanation:
Option A: Offering the child clear liquids for the first 24 hours is not a typical instruction following a cardiac catheterization. After the procedure, the child may be allowed to resume a regular diet, as tolerated, based on the healthcare provider's orders.
Option B: This is the correct instruction. After cardiac catheterization, the child may experience some discomfort at the insertion site or the area where the catheter was threaded through the blood vessels. Acetaminophen can be used to manage mild pain or discomfort.
Option C: Taking a tub bath for the first 3 days is not typically mentioned in discharge instructions after a cardiac catheterization. The nurse might advise the parent to avoid submerging the catheter insertion site in water for a specific period and instead use sponge baths until permitted by the healthcare provider.
Option D: Keeping the child home for 1 week is not a standard recommendation for a cardiac catheterization. The recovery period after a cardiac catheterization is usually shorter, and the child can often resume normal activities within a day or two, depending on the specific circumstances of the procedure and the child's condition.
The nurse should thoroughly review the specific discharge instructions provided by the healthcare provider and ensure the parent understands the care required at home, including any restrictions on activities or signs of potential complications that require immediate attention.
Correct Answer is C
Explanation
Infants with gastroesophageal reflux should be placed in an infant seat or an upright position after feedings to help prevent regurgitation and aspiration of stomach contents into the airway. Placing the infant in an upright position facilitates gravity-assisted movement of stomach contents down and away from the esophagus, reducing the likelihood of reflux. It is essential to ensure that the infant seat is appropriate for the child's age and size and that the infant is safely secured within it.
The other options are not recommended for infants with gastroesophageal reflux:
When caring for an infant with gastroesophageal reflux (GER), the nurse should place the infant in an infant seat or an upright position following feedings. Placing the infant in an upright position helps to reduce the risk of reflux and regurgitation. Gravity can assist in keeping the stomach contents from flowing back into the esophagus, reducing the potential for discomfort and reflux symptoms.
The other options are not recommended for an infant with GER:
A. Placing the infant in a prone position (lying on the stomach) after feedings can increase the risk of choking and aspiration. It is essential to avoid this position, especially after feeding, to reduce the risk of reflux and its complications.
B. Placing the infant on his left side is not the preferred position for GER management. While the left side is often recommended for sleeping to reduce the risk of sudden infant death syndrome (SIDS), it is not specifically indicated for GER management after feedings.
D. Placing the infant on his right side is also not the preferred position for GER management after feedings. The right side does not provide the benefits of an upright position in reducing the risk of reflux and regurgitation.
