Nursing Elites

1. When evaluating the laboratory report of a 1-year-old infant’s hematocrit, a healthcare provider compares it with the expected hematocrit range for this age group. What is the hematocrit of a healthy 12-month-old infant?

• A. 19% to 32%
• B. 29% to 41%
• C. 37% to 47%
• D. 42% to 69%

Correct answer: C

Rationale: The correct hematocrit range for a healthy 12-month-old infant is between 37% to 47%. At this age, this range reflects the normal blood volume and red blood cell (RBC) levels in infants. Choice A (19% to 32%) is too low for a healthy hematocrit level in a 12-month-old. Choice B (29% to 41%) is also below the typical range for a 12-month-old. Choice D (42% to 69%) includes an upper limit that is higher than expected for a healthy infant, making it an incorrect option.

2. 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.

3. An infant is admitted to the neonatal intensive care unit (NICU) with exstrophy of the bladder. What covering should the nurse use to protect the exposed area?

• A. Loose diaper
• B. Dry gauze dressing
• C. Moist sterile dressing
• D. Petroleum jelly gauze pad

Correct answer: C

Rationale: A moist sterile dressing should be used to protect the exposed bladder tissue from infection and injury. Exstrophy of the bladder requires careful management to prevent complications such as infection. A loose diaper (Choice A) may not provide adequate protection or prevent infection. Dry gauze dressing (Choice B) may not be ideal as it could adhere to the exposed area and cause trauma upon removal. Petroleum jelly gauze pad (Choice D) may not be suitable as it can trap moisture and increase the risk of infection.

4. A 2-week-old infant is admitted with a tentative diagnosis of a ventricular septal defect. The parents report that their baby has had difficulty feeding since coming home after birth. What should the nurse consider before responding?

• A. Feeding problems are common in neonates.
• B. Inadequate sucking is not significant unless cyanosis is present.
• C. Ineffective sucking and swallowing may be early indications of a heart defect.
• D. Many neonates retain mucus, which can interfere with feeding for several weeks.

Correct answer: C

Rationale: Ineffective sucking and swallowing can be early signs of a heart defect like a ventricular septal defect. This is crucial information for the nurse to consider as it aligns with the infant's tentative diagnosis. Choice A is too general and does not provide specific relevance to the situation. Choice B is incorrect as inadequate sucking can indeed be significant, especially in the context of a potential heart defect. Choice D is not directly related to the potential heart defect and feeding difficulties mentioned in the scenario.

5. A 6-year-old child with a diagnosis of juvenile idiopathic arthritis (JIA) is being discharged. What should the nurse include in the discharge teaching?

• A. Encourage participation in physical activity
• B. Provide a high-calorie diet
• C. Provide a low-sodium diet
• D. Administer intravenous fluids

Correct answer: A

Rationale: Encouraging regular physical activity is essential in managing symptoms and improving joint function in juvenile idiopathic arthritis. Physical activity helps maintain joint mobility, muscle strength, and overall function. Providing a high-calorie diet may not be necessary unless there are specific concerns about the child's nutritional status. A low-sodium diet is not typically a priority in the management of JIA unless the child has comorbid conditions requiring sodium restriction. Administering intravenous fluids is not a standard discharge teaching for JIA unless there are specific medical indications necessitating it.
