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 healthcare professional is educating a parent group about the importance of immunizations. Which disease can be prevented by the varicella vaccine?

• A. Measles
• B. Mumps
• C. Rubella
• D. Chickenpox

Correct answer: D

Rationale: The varicella vaccine is specifically designed to prevent chickenpox. Measles, mumps, and rubella are prevented by different vaccines (MMR vaccine for measles, mumps, and rubella). Therefore, the correct answer is chickenpox (varicella). It is crucial for healthcare professionals to provide accurate information about vaccines to help ensure the health and well-being of individuals.

3. A child is diagnosed with atopic dermatitis. Which laboratory test would the nurse expect the child to undergo to provide additional evidence for this condition?

• A. Erythrocyte sedimentation rate
• B. Potassium hydroxide prep
• C. Wound culture
• D. Serum immunoglobulin E (IgE) level

Correct answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is a nonspecific test for inflammation and not specific to atopic dermatitis. Choice B, potassium hydroxide prep, is used to diagnose fungal infections like tinea versicolor, not atopic dermatitis. Choice C, wound culture, is not typically indicated for the diagnosis of atopic dermatitis as it is a chronic inflammatory skin condition rather than an infectious process.

4. What finding would lead the nurse to suspect that a child has Turner syndrome?

• A. Webbed neck
• B. Microcephaly
• C. Gynecomastia
• D. Cognitive delay

Correct answer: A

Rationale: A webbed neck is a key feature seen in Turner syndrome, a genetic condition that occurs in females due to a complete or partial absence of one of the X chromosomes. This physical trait is caused by excess skin on the neck, giving it a webbed appearance. Microcephaly (Choice B) is a condition characterized by a smaller than average head size and is not typically associated with Turner syndrome. Gynecomastia (Choice C) refers to breast enlargement in males and is not a common finding in Turner syndrome, which affects females. Cognitive delay (Choice D) is not a specific characteristic of Turner syndrome, as the syndrome primarily affects physical development and may not necessarily impact cognitive abilities.

5. Where should the child admitted with injuries that may be related to abuse be placed?

• A. In a private room
• B. With an older, friendly child
• C. With a child of the same age
• D. In a room near the nurses’ desk

Correct answer: D

Rationale: The correct answer is to place the child in a room near the nurses’ desk. This placement allows for close monitoring and immediate intervention if needed, ensuring the safety and well-being of the child. Placing the child in a private room (Choice A) may limit visibility and monitoring. Putting the child with an older, friendly child (Choice B) or a child of the same age (Choice C) does not prioritize the necessary close monitoring and intervention that a child potentially experiencing abuse requires. Hence, placing the child in a room near the nurses’ desk is the most appropriate choice in this scenario.
