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. An 8-year-old child diagnosed with meningitis is to undergo a lumbar puncture. What should the nurse explain is the purpose of this procedure?

• A. To measure the pressure of cerebrospinal fluid
• B. To obtain a sample of cerebrospinal fluid for analysis
• C. To relieve intracranial pressure
• D. To assess the presence of infection in the spinal fluid

Correct answer: B

Rationale: A lumbar puncture is performed to obtain a sample of cerebrospinal fluid for analysis. This fluid is then examined for signs of infection, bleeding, or other abnormalities. Measuring the pressure of cerebrospinal fluid is typically done during the procedure itself, but it is not the primary purpose of the lumbar puncture. While a lumbar puncture can indirectly help relieve intracranial pressure by removing excess cerebrospinal fluid, this is not its primary purpose. Assessing the presence of infection in the spinal fluid is part of the analysis that follows the collection of the sample, making it a secondary outcome of the procedure.

3. A healthcare professional plans to discuss childhood nutrition with a group of parents whose children have Down syndrome in an attempt to minimize a common nutritional problem. What problem should be addressed?

• A. Rickets
• B. Obesity
• C. Anemia
• D. Rumination

Correct answer: B

Rationale: The correct answer is B: Obesity. Children with Down syndrome are at a higher risk of obesity due to various factors such as lower metabolic rate, hormonal imbalances, and reduced physical activity levels. Addressing healthy eating habits early can help prevent obesity in these children. Choice A (Rickets) is incorrect because rickets is primarily associated with vitamin D deficiency and is not a common nutritional problem in children with Down syndrome. Choice C (Anemia) is incorrect as anemia may not be a common nutritional problem specific to children with Down syndrome. Choice D (Rumination) is incorrect as rumination is a behavioral disorder characterized by repeated regurgitation of food and is not a common nutritional problem associated with Down syndrome.

4. What is one of the most important factors that a healthcare professional must consider when parents of a toddler request to be present at a procedure occurring on the hospital unit?

• A. Type of procedure to be performed
• B. Individual assessment of the parents
• C. Whether the toddler wants the parents present
• D. Probable reaction to the toddler’s response to pain

Correct answer: B

Rationale: When parents of a toddler request to be present during a procedure, an individual assessment of the parents is crucial. This assessment helps healthcare professionals understand the parents' ability to cope with the situation, provide support to their child, and ensure a conducive environment for the procedure. Choice A is not as critical because the focus is on the parents' readiness rather than the specific procedure. Choice C, considering the toddler's desire, is important but not as crucial as assessing the parents. Choice D, anticipating the toddler's response to pain, is relevant but secondary to assessing the parents' readiness and support capabilities.

5. An infant with hypertrophic pyloric stenosis (HPS) is admitted to the pediatric unit. What does the nurse expect when palpating the infant’s abdomen?

• A. A distended colon
• B. Marked tenderness around the umbilicus
• C. An olive-sized mass in the right upper quadrant
• D. Rhythmic peristaltic waves in the lower abdomen

Correct answer: C

Rationale: When palpating the abdomen of an infant with hypertrophic pyloric stenosis (HPS), the nurse would expect to feel an olive-sized mass in the right upper quadrant. This finding is characteristic of HPS due to the hypertrophied pylorus muscle. Choices A, B, and D are incorrect. A distended colon is not typically associated with HPS. Marked tenderness around the umbilicus is not a specific finding of HPS. Rhythmic peristaltic waves in the lower abdomen are not expected in HPS, as the condition primarily affects the pylorus region of the stomach.
