Question

question 30 (1 point) ✔ saved listen if an infant begins projectile vomiting in the second to fourth week after birth, a primary care provider might suspect: cystic fibrosis. hirschsprung disease. pyloric stenosis. cardiac stenosis. question 31 (1 point) listen which of the following is an acyanotic defect? ventricular septal defect transposition of the great arteries tetralogy of fallot tricuspid atresia

Explanation:

For Question 30: Projectile vomiting in infants 2-4 weeks after birth is a classic hallmark of pyloric stenosis, where the pylorus muscle thickens, blocking stomach emptying. Cystic fibrosis primarily affects the respiratory and digestive systems with different early symptoms, Hirschsprung disease causes bowel obstruction issues, and cardiac stenosis impacts heart function unrelated to this vomiting pattern.
For Question 31: Acyanotic heart defects involve left-to-right shunts without oxygen-poor blood entering systemic circulation. Ventricular septal defect is an acyanotic defect, while transposition of the great arteries, tetralogy of Fallot, and tricuspid atresia are cyanotic defects that result in deoxygenated blood circulating in the body.

Answer:

Question 30: Pyloric stenosis.
Question 31: Ventricular septal defect
