While assessing a newborn with respiratory distress, the nurse auscultates a machine-like heart murmur. Other findings are a widened pulse pressure. pulmonary congestion and right ventricular hypertrophy. The nurse suspects that the newborn has:

Kawasaki disease

Tricuspid Atresia

Tetralogy of Fallot

Patent Ductus Arteriosus (PDA)

Answer and Explanation

The Correct Answer is D

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 C

Explanation

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.

A. Croup B. Epiglottitis C. Bronchiolitis D. Laryngotracheobronchitis

Correct Answer is B

C. Bronchiolitis is usually caused by respiratory syncytial virus (RSV) and presents with wheezing, cough, and respiratory distress but not typically with drooling or difficulty swallowing.
