Nursing Elites

1. The nurse is teaching a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?

• A. Myelination continues into adolescence and beyond.
• B. The process occurs in a cephalocaudal (head-to-toe) pattern.
• C. Myelination decreases the speed of nerve impulses.
• D. Myelination decreases the specificity of nerve impulses.

Correct answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.

2. A child with a diagnosis of sickle cell anemia is experiencing a vaso-occlusive crisis. What is the most important nursing intervention?

• A. Administering oxygen
• B. Administering pain medication
• C. Monitoring fluid intake
• D. Encouraging physical activity

Correct answer: B

Rationale: During a vaso-occlusive crisis in sickle cell anemia, the most important nursing intervention is to administer pain medication. Pain management is crucial in alleviating the intense pain experienced by the patient. Administering oxygen (Choice A) may be necessary in some cases to improve oxygenation, but pain relief takes precedence during a vaso-occlusive crisis. Monitoring fluid intake (Choice C) is important for hydration but is not the priority during a crisis. Encouraging physical activity (Choice D) is contraindicated during a vaso-occlusive crisis as it can exacerbate pain and tissue damage.

3. During a health assessment of a school-age child, where should the nurse focus more attention based on the child's developmental level?

• A. Infections
• B. Poisonings
• C. Risk-taking behaviors
• D. Accidents and injuries

Correct answer: D

Rationale: During the school-age period, children are active, curious, and engaged in various physical activities, making them more susceptible to accidents and injuries. This developmental stage is characterized by increased motor skills and exploration, leading to a higher risk of unintentional harm. While infections, poisonings, and risk-taking behaviors are also concerns for school-age children, focusing on preventing and addressing accidents and injuries is essential due to their heightened physical activity and curiosity.

4. When describing urticaria, what would an instructor include?

• A. It is a type IV hypersensitivity reaction.
• B. Histamine release leads to vasodilation.
• C. Wheals appear first followed by erythema.
• D. The nonpruritic rash blanches with pressure.

Correct answer: B

Rationale: The correct answer is B. Urticaria is a type I hypersensitivity reaction where histamine release leads to vasodilation and the formation of characteristic wheals. Choice A is incorrect as urticaria is associated with type I hypersensitivity, not type IV. Choice C is incorrect because in urticaria, erythema typically appears before the development of wheals. Choice D is incorrect as urticaria is typically pruritic and does not blanch with pressure.

5. During the health assessment of a school-age child, on which problem would the nurse focus more attention based on the child's developmental level?

• A. Infections
• B. Poisonings
• C. Risk-taking behaviors
• D. Accidents and injuries

Correct answer: D

Rationale: During the school-age years, children are more physically active and curious, which increases their risk of accidents and injuries. This developmental stage is characterized by increased exploration and engagement in physical activities. While infections and poisonings are important health concerns, school-age children are more likely to be affected by accidents and injuries due to their active nature. Risk-taking behaviors may become more prevalent in adolescence rather than during the school-age period, making it a less likely focus for the nurse during the health assessment of a school-age child.
