1. Which parental statement at the conclusion of a teaching session regarding environmental controls for childhood asthma indicates correct understanding of the information presented?

Correct answer: D

Rationale: The correct answer is D. Replacing carpet with hard flooring helps to reduce allergens and asthma triggers in the child’s environment. Choice A is incorrect as having a dog in the child’s room can worsen asthma symptoms due to pet dander. Choice B is incorrect because keeping plants in the child’s room can increase mold spores and allergens. Choice C is incorrect as using a fireplace can introduce smoke and other irritants into the air, worsening asthma symptoms.

2. Which congenital heart defect causes a "boot-shaped" heart on a chest x-ray?

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot, a congenital heart defect with four distinct abnormalities, often presents with a "boot-shaped" heart on chest x-ray due to right ventricular hypertrophy. This characteristic finding is due to the specific combination of defects in this condition. Coarctation of the aorta (choice B), Transposition of the great arteries (choice C), and Ventricular septal defect (choice D) do not typically result in a "boot-shaped" heart on a chest x-ray like Tetralogy of Fallot does.

3. Which is described as an elevated, circumscribed skin lesion that is less than 1 cm in diameter and filled with serous fluid?

Correct answer: D

Rationale: A vesicle is an elevated, circumscribed lesion filled with serous fluid, typically less than 1 cm in diameter.

4. The presence of which pair of factors is a good predictor of a fluid deficit of at least 5% in an infant?

Correct answer: D

Rationale: Dry mucous membranes and an ill appearance are good indicators of dehydration in infants, often correlating with a fluid deficit of at least 5%. Sunken fontanels and poor skin turgor are also indicative but were not options here.

5. An infant weighed 8 lb at birth and was 18 inches in length. What weight and length should the infant be at 5 months of age?

Correct answer: C

Rationale: By 5 months, an infant's weight should typically double from birth, and length should increase by approximately 50%.
