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 usually the only symptom of pediculosis capitis (head lice)?

• A. Itching
• B. Vesicles
• C. Scalp rash
• D. Localized inflammatory response

Correct answer: A

Rationale: Itching is typically the primary and most common symptom of pediculosis capitis due to the lice bites on the scalp.

3. Which sign is indicative of developmental dysplasia of the hip in infants?

• A. Ortolani sign
• B. Romberg sign
• C. Trendelenburg sign
• D. Gower's sign

Correct answer: A

Rationale: The Ortolani sign is a specific maneuver used during physical examination to detect hip instability or dislocation in infants. A positive Ortolani sign, where the hip is felt to slip back into the socket, is indicative of developmental dysplasia of the hip, a condition that can lead to long-term disability if not treated early. Romberg sign is used to assess sensory ataxia, Trendelenburg sign indicates weakness of the hip abductor muscles, and Gower's sign is seen in children with proximal muscle weakness climbing up their own body from a supine position due to conditions like muscular dystrophy.

4. The nurse is planning an educational session for a group of 9-year-olds and their parents aimed at decreasing injuries and accidents among this age group. Which topics should be included in the educational session to accomplish the goal?

• A. Safety rules when dealing with fire to prevent burns.
• B. Safety rules when dealing with toxic substances to prevent poisonings.
• C. Pedestrian, motor vehicle, and bike safety rules.
• D. Safety information regarding the use of all-terrain vehicles (ATVs).

Correct answer: C

Rationale: For school-aged children, pedestrian, motor vehicle, and bike safety are critical areas to focus on as accidents involving these are common in this age group. Education about fire safety and toxic substances is also important, but the priority is on preventing accidents in everyday activities. Therefore, choices A, B, and D are not the most relevant for addressing the goal of decreasing injuries and accidents in this age group.

5. What is characteristic of a neonate’s vision?

• A. Pupils react to light
• B. Tear glands function
• C. Blink reflex is absent
• D. Ciliary muscles are mature

Correct answer: A

Rationale: The correct answer is A: 'Pupils react to light.' Newborns' pupils do react to light, indicating that the visual pathway is functioning. However, a neonate's vision is still developing, and they can only focus on objects close to their face. Choice B is incorrect because tear glands are functional at birth. Choice C is incorrect because the blink reflex is present in neonates and helps protect their eyes. Choice D is incorrect as neonates' ciliary muscles are not fully developed.
