an infant presents with a new grade iv/vi systolic ejection murmur. chest x - ray reveals a boot - shaped heart. what is the most likely diagnosis?

• ventricular septal defect
• coarctation of the aorta
• aortic stenosis
• tetralogy of fallot

question 15

Explanation:

Question 13

Meconium ileus is strongly associated with cystic fibrosis (CF) in newborns. CF affects the exocrine glands, leading to thick mucus that can cause intestinal obstruction like meconium ileus. Congenital heart disease, diaphragmatic hernia, and pulmonary airway malformation are not typically linked to meconium ileus as closely as CF.

Tetralogy of Fallot (TOF) is a congenital heart defect with four components, including pulmonary stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. A boot - shaped heart on chest X - ray and a systolic ejection murmur (due to pulmonary stenosis) are classic findings of TOF. Ventricular septal defect usually has a different X - ray appearance and murmur characteristics. Coarctation of the aorta and aortic stenosis do not present with a boot - shaped heart.

Answer:

A. cystic fibrosis.
