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 is the most frequently used test for measuring visual acuity?

• A. Snellen letter chart
• B. Ishihara vision test
• C. Allen picture card test
• D. Denver eye screening test

Correct answer: A

Rationale: The Snellen letter chart is the most commonly used test for measuring visual acuity, particularly in school-age children and adults.

3. The nurse is teaching a client to prevent future urinary tract infections (UTIs). What factor is most important to emphasize as the potential cause?

• A. Poor hygiene
• B. Constipation
• C. Urinary stasis
• D. Congenital anomalies

Correct answer: C

Rationale: Urinary stasis is the most important factor in the development of UTIs because it provides an environment for bacterial growth. While poor hygiene and congenital anomalies are contributing factors, preventing urinary stasis is key in UTI prevention.

4. The nurse is selecting a site to begin an intravenous infusion on a 2-year-old child. The superficial veins on his hand and arm are not readily visible. What intervention should increase the visibility of these veins?

• A. Gently tap over the site.
• B. Apply a cold compress to the site.
• C. Raise the extremity above the level of the body
• D. Use a rubber band as a tourniquet for 5 minutes.

Correct answer: A

Rationale: Gently tapping over the site helps dilate the veins and increase visibility. Applying a cold compress or raising the extremity above the body level constricts the veins, making them harder to access. Prolonged tourniquet use can cause discomfort and venous congestion.

5. Which statement regarding bottle mouth caries requires further teaching?

• A. Caries can be decreased by putting an infant to bed with a bottle of milk or sweetened juice
• B. Eliminating the bedtime bottle or substituting water is recommended
• C. Sugar pools within the oral cavity cause severe decay
• D. It is often seen in children between 18 months and 3 years

Correct answer: A

Rationale: The correct answer is A. Putting an infant to bed with a bottle of milk or sweetened juice increases the risk of bottle mouth caries rather than decreasing it. This statement requires further teaching as it provides incorrect information. Choice B is correct as eliminating the bedtime bottle or substituting water is recommended to prevent bottle mouth caries. Choice C is also correct as sugar pooling within the oral cavity can indeed cause severe decay. Choice D is correct as bottle mouth caries is often observed in children between 18 months and 3 years.
