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.

B. Bradycardia is not a typical manifestation of sickle cell crisis. The patient might experience tachycardia due to pain or dehydration.
C. Pain is the hallmark symptom of a sickle cell crisis. The sickle-shaped red blood cells obstruct blood flow, leading to ischemia and severe pain, often in the joints or abdomen.
D. Fever can occur if there is an infection, but pain is the most characteristic finding in a sickle cell crisis.
