Question 1 of 5
In which congenital heart defect would the nurse need to take upper and lower extremity blood pressures?
Correct Answer: C
Rationale: The correct answer is C: Coarctation of the Aorta (CO
A). In COA, there is a narrowing of the aorta leading to increased blood pressure in the upper extremities and decreased pressure in the lower extremities. By taking blood pressures in both arms and legs, the nurse can assess for this characteristic blood pressure differential. Aortic stenosis (
A) primarily affects the aortic valve, not causing differential blood pressures. Transposition of the Great Vessels (
B) involves aorta and pulmonary artery switching positions, not affecting blood pressures in extremities. Tetralogy of Fallot (
D) involves pulmonary stenosis, right ventricular hypertrophy, VSD, and overriding aorta, not causing differential blood pressures.
