In which congenital heart defect would the nurse need to take upper and lower extremity blood pressures?

A.

Aortic stenosis (AS)

B.

Transposition of the Great Vessels (Arteries)

C.

Coarctation of the Aorta (COA)

D.

Tetralogy of Fallot (TOF)

Answer and Explanation

The Correct Answer is C

A. Aortic stenosis (AS) typically causes a difference in blood flow across the aortic valve but does not usually require assessment of upper and lower extremity blood pressures.

B. Transposition of the Great Vessels (Arteries) results in cyanosis and abnormal circulatory flow but does not require upper and lower extremity blood pressure monitoring.

C. Coarctation of the Aorta (COA) is characterized by narrowing of the aorta, often resulting in higher blood pressure in the upper extremities compared to the lower extremities. Measuring both helps identify this condition.

D. Tetralogy of Fallot (TOF) involves right ventricular outflow obstruction, VSD, overriding aorta, and right ventricular hypertrophy, but upper and lower extremity blood pressures are not typically used for diagnosis.

Correct Answer is D

Explanation

A. Kawasaki disease typically presents with fever, rash, and conjunctivitis, not a machine-like murmur or the other cardiovascular findings.

B. Tricuspid Atresia involves a defect in the tricuspid valve and presents with cyanosis and poor circulation, but not a machine-like murmur.

C. Tetralogy of Fallot involves a murmur due to pulmonary stenosis and VSD but would not produce a "machine-like" murmur, which is characteristic of PDA.

D. Patent Ductus Arteriosus (PDA) results in a continuous "machine-like" murmur due to abnormal blood flow between the aorta and pulmonary artery, along with findings of pulmonary congestion and right ventricular hypertrophy.

Correct Answer is B

Explanation

A. Place the patch on the right eye for several hours daily would not be effective for treating amblyopia. The goal of patching is to encourage the use of the weaker (lazy) eye, so the good eye (left) must be patched.

B. Place the patch on the left eye for several hours daily is the correct approach to treat amblyopia, as it forces the right (weaker) eye to work and improve visual acuity.

C. Place the patch on the right eye for one hour daily would not effectively treat the amblyopia in the left eye, as it focuses on the wrong eye.

D. Alternate the patch from the right to the left eye hourly is not typically done. Consistent patching of the stronger (left) eye is recommended.
