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. What should be taught to the child and parents about using a peak flow meter for a child diagnosed with asthma?

• A. Use the device before taking medication
• B. Use the device during asthma attacks
• C. Record the best of three attempts
• D. Use the device after eating

Correct answer: C

Rationale: The correct answer is to 'Record the best of three attempts.' This method provides an accurate measure of peak expiratory flow using a peak flow meter. By taking the best of three attempts, the child and parents can obtain a more reliable assessment of the child's lung function. Choices A, B, and D are incorrect because using the device before taking medication, during asthma attacks, or after eating does not ensure an accurate measurement of peak flow, which is essential for managing asthma effectively. Monitoring peak flow regularly and accurately can help in adjusting asthma treatment plans and assessing response to medications.

3. What is the priority intervention for a 10-year-old girl in a foster family?

• A. Determining if the child is being bullied at school
• B. Dealing with mixed parental expectations
• C. Establishing the child's primary caretaker
• D. Performing a comprehensive health assessment

Correct answer: D

Rationale: In a foster family setup, the priority intervention for a 10-year-old girl is to perform a comprehensive health assessment. This is crucial as children in foster care may have moved between different homes, leading to incomplete medical records. A comprehensive health assessment helps identify any health issues, track the child's growth and development, and ensure appropriate medical care. While addressing bullying at school, managing parental expectations, and establishing the primary caretaker are important considerations, the immediate priority for the child's well-being and holistic care is to conduct a thorough health assessment.

4. 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 not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.

5. After instituting ordered measures to reduce the fever in a 3-year-old with fever and vomiting, what nursing action is most important for the nurse in the emergency department to take?

• A. Preventing shivering
• B. Restricting oral fluids
• C. Measuring output hourly
• D. Taking vital signs hourly

Correct answer: A

Rationale: Preventing shivering is crucial in this situation as it can increase the body temperature and counteract the effects of antipyretic measures aimed at reducing the fever. Shivering generates heat, potentially worsening the fever. Restricting oral fluids (Choice B) is not appropriate as fluid intake is important to prevent dehydration, especially in a child who has been vomiting. Measuring output hourly (Choice C) and taking vital signs hourly (Choice D) are important nursing actions but not as critical as preventing shivering in this scenario. Therefore, the most important nursing action is to prevent shivering to aid in fever reduction and management.
