Nursing Elites

1. The parents of a child with sickle cell anemia ask why their child did not have a sickle cell crisis until he was approximately 6 months old. How should the nurse respond?

• A. Your child probably had a crisis, and you were unaware of the symptoms.
• B. Are you sure your child has sickle cell anemia and not sickle cell trait?
• C. Affected children can be asymptomatic in early infancy because of high levels of fetal hemoglobin that inhibit sickling.
• D. Have you asked your doctor about this yet?

Correct answer: C

Rationale: The correct answer is C. Fetal hemoglobin (HbF) is present in high levels during early infancy, inhibiting sickling unlike adult hemoglobin (HbS). As the levels of HbF decrease and HbS increases, the risk of sickling and crises becomes more pronounced, typically after 6 months of age. Choice A is incorrect because it assumes the crisis went unnoticed, which is not supported by medical knowledge. Choice B is incorrect as it questions the child's diagnosis rather than explaining the phenomenon of delayed crises. Choice D is incorrect as it does not provide the parents with the necessary information regarding their query.

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

• A. ''We're glad the dog can continue to sleep in our child’s room.''
• B. ''We’ll keep the plants in our child’s room dusted.''
• C. ''We’ll be sure to use the fireplace often to keep the house warm in the winter.''
• D. ''We will replace the carpet in our child’s bedroom with a hard surface.''

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.

3. 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.

4. The clinic nurse is reviewing the immunization guidelines for hepatitis B. Which are true of the guidelines for this vaccine?

• A. The hepatitis B vaccination series should be begun at birth
• B. All are applicable
• C. Any child not vaccinated at birth should receive two doses at least 4 months apart
• D. An unimmunized 10-year-old child should receive three doses administered 4 weeks apart

Correct answer: B

Rationale: Hepatitis B vaccination should start at birth, and any child or adolescent not vaccinated should complete the series. Adolescents should receive three doses if they were not previously vaccinated.

5. What is the typical presentation of pyloric stenosis in infants?

• A. Bilious vomiting
• B. Projectile vomiting
• C. Blood in stools
• D. Failure to thrive

Correct answer: B

Rationale: The correct answer is B: Projectile vomiting. Pyloric stenosis in infants typically presents with projectile vomiting, which is forceful and projective in nature. This occurs due to the obstruction at the pylorus, leading to the stomach being unable to empty properly. Choices A, C, and D are incorrect. Bilious vomiting is more commonly associated with intestinal obstruction, blood in stools can occur in conditions such as necrotizing enterocolitis or allergic colitis, and failure to thrive is a nonspecific finding that can be seen in various pediatric conditions.
