1. Which finding suggests fluid volume deficit in an infant presenting with vomiting and diarrhea for 2 days?

• A. Increased blood pressure
• B. A sunken fontanel
• C. Decreased pulse rate
• D. Low urine specific gravity

Correct answer: B

Rationale: A sunken fontanel is a classic sign of dehydration in infants, indicating a fluid volume deficit. In dehydration, the fontanel sinks due to decreased fluid volume in the body. Increased blood pressure (Choice A) is not typically associated with dehydration in infants. Decreased pulse rate (Choice C) is not a common finding in fluid volume deficit, as the body tries to increase the heart rate to compensate for decreased volume. Low urine specific gravity (Choice D) may be seen in dehydration, but it is not as specific or as easily observable as a sunken fontanel.

2. When should a child receive the first dose of the hepatitis B virus (HBV) vaccine if the mother is hepatitis B surface antigen (HBsAg) negative?

• A. 2 months of age, before hospital discharge.
• B. Birth before discharge from the hospital.
• C. 6 months of age, at the third well-child visit.
• D. No time (this vaccine is not currently recommended).

Correct answer: B

Rationale: If the mother is HBsAg negative, it is recommended that the child receives the first dose of the hepatitis B vaccine at birth before discharge from the hospital. This is to provide early protection against the hepatitis B virus. The second dose of the vaccine is typically given at the first well-child visit, and the third dose is usually administered at a later date. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention and the Committee on Infectious Diseases of the American Academy of Pediatrics govern the recommendations for immunization, including the hepatitis B virus vaccine. Choice A is incorrect as the first dose should ideally be given at birth. Choice C is incorrect as waiting until 6 months of age may leave the child vulnerable to infection during the early months of life. Choice D is incorrect as the hepatitis B vaccine is recommended for all newborns, especially if the mother is HBsAg negative, to prevent transmission of the virus.

3. The nurse is teaching parents about high-fiber foods that can prevent constipation. What foods should the nurse include in the teaching?

• A. Oranges
• B. All are correct
• C. Lima beans
• D. Baked beans

Correct answer: B

Rationale: The correct answer is B: All are correct. High-fiber foods like oranges, lima beans, baked beans, and raisin bran cereal are effective in preventing constipation. Oranges are a good source of fiber, lima beans and baked beans are high in fiber content, and raisin bran cereal is also rich in fiber. Bananas, which are not listed but could be considered by some as a high-fiber food, are actually low in fiber and may not be as effective in preventing constipation. Therefore, the nurse should include all the options provided in the teaching to help prevent constipation effectively.

4. At what age is it safe to give infants whole milk instead of commercial infant formula?

• A. 6 months
• B. 9 months
• C. 12 months
• D. 18 months

Correct answer: C

Rationale: Whole milk should not be introduced before 12 months because it lacks the necessary nutrients, such as iron, that infants need for proper growth and development.

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?

• A. 12 lb, 20 inches
• B. 14 lb, 21.5 inches
• C. 16 lb, 23 inches
• D. 18 lb, 24.5 inches

Correct answer: C

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