Nursing Elites

1. By what age does birth weight usually triple?

• A. 1 year
• B. 1 month
• C. 2 years
• D. 6 months

Correct answer: A

Rationale: The correct answer is A: 1 year. By the age of 1 year, a baby’s birth weight typically triples. This period allows for significant growth and development in infants. Choices B, C, and D are incorrect because birth weight does not usually triple by 1 month, 2 years, or 6 months of age, respectively.

2. Which pediatric disorder is associated with a 'boot-shaped' heart on a chest x-ray?

• A. Tetralogy of Fallot
• B. Transposition of the great arteries
• C. Coarctation of the aorta
• D. Ventricular septal defect

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot is often associated with a 'boot-shaped' heart appearance on a chest x-ray due to the characteristic heart anatomy in this condition. This appearance is caused by the combination of pulmonary stenosis, overriding aorta, ventricular septal defect, and right ventricular hypertrophy. Choice B, Transposition of the great arteries, is incorrect because it presents with a 'egg-on-a-string' appearance on x-ray due to the abnormal position of the aorta and pulmonary artery. Choice C, Coarctation of the aorta, typically presents with rib notching on x-ray. Choice D, Ventricular septal defect, does not produce the 'boot-shaped' heart appearance seen in Tetralogy of Fallot.

3. The nurse's approach when introducing hospital equipment to a preschooler who seems afraid should be based on which principle?

• A. The child may think the equipment is alive.
• B. Explaining the equipment will only increase the child’s fear
• C. One brief explanation will be enough to reduce the child’s fear
• D. The child is too young to understand what the equipment does

Correct answer: A

Rationale: Preschoolers may engage in magical thinking and believe inanimate objects are alive, so the nurse should explain the equipment in a way that reduces fear.

4. The parents of a 2-year-old boy who had a repair of exstrophy of the bladder at birth ask when they can begin toilet training their son. The nurse replies based on what knowledge?

• A. Most boys in the United States can be toilet trained at age 3 years.
• B. Training can begin when he has sufficient bladder capacity.
• C. Additional surgery may be necessary to achieve continence.
• D. They should begin now because he will require additional time.

Correct answer: B

Rationale: Toilet training should begin when the child has sufficient bladder capacity and control, which may be delayed in children who have undergone surgical repairs for conditions like bladder exstrophy. Premature training can lead to frustration and setbacks.

5. What is the primary goal in the treatment of a child with nephrotic syndrome?

• A. Decrease urine output
• B. Increase serum albumin
• C. Reduce proteinuria
• D. Increase blood pressure

Correct answer: C

Rationale: The primary goal in treating nephrotic syndrome in children is to reduce proteinuria. Nephrotic syndrome is characterized by proteinuria, leading to hypoalbuminemia and edema. By reducing proteinuria, kidney damage can be minimized, and symptoms can be managed effectively. Decreasing urine output (Choice A) is not the primary goal, as it does not address the underlying issue of protein loss. Increasing serum albumin (Choice B) is a consequence of reducing proteinuria rather than the primary goal. Increasing blood pressure (Choice D) is not a goal in treating nephrotic syndrome and may even be contraindicated to prevent further kidney damage.
