Nursing Elites

1. The parent of an 8.2-kg (18-lb) 9-month-old infant is borrowing a federally approved car seat from the clinic. The nurse should explain that the safest way to put in the car seat is what?

• A. Front facing in back seat
• B. Rear facing in back seat
• C. Front facing in front seat with air bag on passenger side
• D. Rear facing in front seat if an air bag is on the passenger side

Correct answer: B

Rationale: Infants should be placed rear-facing in the back seat until they are at least 2 years old or exceed the weight/height limit of their car seat for optimal safety.

2. The nurse is caring for a 1-month-old infant diagnosed with Hirschsprung’s disease. Which treatment measure should be included in the plan of care?

• A. Barium Enema
• B. Surgical removal of the affected section of bowel
• C. High-fiber diet
• D. Permanent colostomy

Correct answer: B

Rationale: The correct answer is B: Surgical removal of the affected section of bowel. Hirschsprung's disease is a congenital condition where a portion of the large intestine lacks nerve cells, leading to difficulties in passing stool. The definitive treatment for this condition is the surgical removal of the affected section of the bowel. Barium enema (Choice A) may be used for diagnosis but is not a treatment. A high-fiber diet (Choice C) is not effective in managing Hirschsprung's disease. A permanent colostomy (Choice D) is not the initial treatment for this condition in infants.

3. Which condition is often associated with a "ground-glass" appearance on a chest x-ray in neonates?

• A. Pneumonia
• B. Respiratory distress syndrome
• C. Bronchopulmonary dysplasia
• D. Congenital diaphragmatic hernia

Correct answer: B

Rationale: The correct answer is B, Respiratory distress syndrome. Respiratory distress syndrome often presents with a "ground-glass" appearance on a chest x-ray in neonates due to surfactant deficiency. Choice A, Pneumonia, typically appears as patchy infiltrates on chest x-ray. Choice C, Bronchopulmonary dysplasia, is characterized by hyperinflation and fibrosis, not a ground-glass appearance. Choice D, Congenital diaphragmatic hernia, usually shows mediastinal shift and bowel loops in the chest cavity on x-ray, not a ground-glass appearance.

4. Apgar scoring is conducted at 1 minute and 5 minutes after birth. It is used to determine:

• A. Major body systems’ responses at birth
• B. Future intelligence of the newborn
• C. Level of parent and newborn interaction
• D. Gestational age of the newborn

Correct answer: A

Rationale: The Apgar score assesses a newborn's physical condition immediately after birth by evaluating heart rate, respiratory effort, muscle tone, reflex response, and color. Therefore, the correct answer is A. The other choices are incorrect because B) the Apgar score does not predict future intelligence, C) it does not measure parent and newborn interaction, and D) it is not used to determine gestational age.

5. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed
• B. Flexed posture favors heat loss
• C. A large body surface area favors heat loss to the environment
• D. A thick layer of subcutaneous fat provides excellent insulation

Correct answer: C

Rationale: Newborns have a large surface area relative to their body weight, making them more susceptible to heat loss and requiring careful thermoregulation. Choice A is incorrect because renal function is not directly related to thermoregulation. Choice B is incorrect because a flexed posture actually helps reduce heat loss by minimizing the surface area exposed to the environment. Choice D is incorrect because neonates have limited subcutaneous fat, which contributes to their susceptibility to heat loss.
