Nursing Elites

1. A healthcare professional is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the professional identify as the cause of the polycythemia?

• A. Low tissue oxygen needs
• B. Tissue oxygen needs
• C. Diminished iron level
• D. Hypertrophic cardiac muscle

Correct answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs as the body's response to chronic hypoxia by increasing RBC production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect, the heart's structure causes reduced oxygen levels in the blood. This chronic hypoxia stimulates the bone marrow to produce more red blood cells, leading to an elevated RBC count. Choice A is incorrect as low blood pressure is not directly related to polycythemia in this context. Choice C, diminished iron level, is not the cause of polycythemia in tetralogy of Fallot. Choice D, hypertrophic cardiac muscle, is not the primary cause of the elevated RBC count in this case.

2. The instructor is educating 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.
• B. The process occurs in a head-to-toe fashion.
• C. Myelination speeds up nerve impulses.
• D. Myelination increases the specificity and efficiency 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 because myelination continues beyond 4 years of age and into adolescence. Choice C is incorrect as myelination speeds up nerve impulses rather than slowing them down. Choice D is incorrect because myelination increases the specificity and efficiency of nerve impulses, making them more focused and precise.

3. 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.

4. A child with a diagnosis of nephrotic syndrome is being discharged. What dietary instructions should the nurse provide?

• A. Encourage a high-protein diet
• B. Avoid foods high in salt
• C. Encourage a low-sodium diet
• D. Encourage a low-protein diet

Correct answer: B

Rationale: For a child with nephrotic syndrome, it is crucial to avoid foods high in salt to manage symptoms and prevent complications. Excessive salt intake can lead to fluid retention and exacerbate edema, which are common issues in nephrotic syndrome. Encouraging a high-protein diet (Choice A) may put additional strain on the kidneys and worsen the condition. While protein restriction is sometimes needed, it is not the primary dietary concern in nephrotic syndrome. Similarly, a low-protein diet (Choice D) is not typically recommended as it may lead to malnutrition in children. Although a low-sodium diet (Choice C) may sound similar to avoiding foods high in salt, the emphasis should be on reducing salt intake specifically, rather than a generalized low-sodium approach.

5. 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.
