The nurse is caring for a newly-admitted infant diagnosed with "failure to thrive." The nurse begins to implement the healthcare provider prescribed orders by taking blood pressures in all four extremities. Which congenital cardiac defect does the nurse anticipate based on the prescribed order?
Pulmonary atresia
Tetralogy of Fallot
Ventricular septal defect
Coarctation of the aorta
The Correct Answer is D
A. Pulmonary atresia involves a blockage of blood flow to the lungs, but it does not specifically lead to differences in blood pressure in the extremities.
B. Tetralogy of Fallot involves four defects, but it does not directly correlate with differences in blood pressure between the extremities.
C. A ventricular septal defect can cause heart failure, but it typically doesn’t affect blood pressure in the extremities.
D. Coarctation of the aorta is a congenital defect where the aorta is narrowed, leading to higher blood pressure in the upper extremities and lower blood pressure in the lower extremities. This is why blood pressures are measured in all four extremities to identify this condition.

Correct Answer is ["A","B","C","E"]
Explanation
A. Pulmonary stenosis is one of the characteristic features of TOF, causing obstruction to blood flow to the lungs.
B. Overriding aorta is a defining feature of TOF, where the aorta is positioned over the ventricular septal defect, leading to mixing of oxygenated and deoxygenated blood.
C. Right ventricular hypertrophy occurs in TOF due to increased workload on the right ventricle caused by pulmonary stenosis.
D. Coarctation of the aorta is not part of Tetralogy of Fallot; it is a separate congenital defect.
E. A ventricular septal defect is the hole between the ventricles in TOF, leading to the mixing of oxygenated and deoxygenated blood.
Correct Answer is A
Explanation
A. Bananas are a safe food choice for a 2-year-old, as they are soft and easy to chew, reducing the risk of choking.
B. Grapes should be cut into smaller pieces to prevent choking, as they are a common choking hazard for young children.
C. Celery can be difficult for a toddler to chew and may pose a choking risk, especially if not cut properly.
D. Raw carrots are hard and may pose a choking risk, especially if not cut into small, manageable pieces.
