Nursing Elites

1. Why might a healthcare provider question a health care provider's order for a tap water enema for a 6-month-old infant with suspected Hirschsprung disease?

• A. The result could lead to loss of necessary nutrients.
• B. It could cause a fluid and electrolyte imbalance.
• C. It could increase the fear of intrusive procedures.
• D. The result could cause shock from a sudden drop in temperature.

Correct answer: B

Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas are unlikely to lead to loss of necessary nutrients. Choice C is incorrect as it does not directly relate to the physiological risk of tap water enemas. Choice D is incorrect as shock from a sudden drop in temperature is not a common concern with tap water enemas.

2. A healthcare professional is reviewing the clinical records of infants and children with cardiac disorders who developed heart failure. What did the healthcare professional determine is the last sign of heart failure?

• A. Tachypnea
• B. Tachycardia
• C. Peripheral edema
• D. Periorbital edema

Correct answer: C

Rationale: Peripheral edema is often the last sign of heart failure in infants and children as it indicates significant fluid retention and circulatory compromise. Tachypnea (Choice A) and tachycardia (Choice B) are early signs of heart failure due to the body's compensatory mechanisms. Periorbital edema (Choice D) can occur in heart failure but is not typically the last sign; it is more commonly associated with renal or hepatic dysfunction.

3. A nurse is planning an evening snack for a child receiving Novolin N insulin. What is the reason for this nursing action?

• A. To encourage the child to stay on the diet.
• B. Energy is needed for immediate utilization.
• C. Extra calories will help the child gain weight.
• D. Nourishment helps to counteract late insulin activity.

Correct answer: D

Rationale: The correct answer is D. Novolin N insulin peaks in the evening, leading to a higher risk of hypoglycemia during this time. Providing a snack before bedtime helps counteract the late insulin activity and prevent hypoglycemia. Choice A is incorrect as the primary reason for the snack is related to insulin activity rather than diet compliance. Choice B is not directly related to the timing of Novolin N insulin administration. Choice C is unrelated to the specific need for a snack in the evening to address insulin activity.

4. 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.

5. When preparing a 2-year-old child for surgery, what preoperative teaching should be provided to help them understand the procedure?

• A. Explaining the procedure in simple terms
• B. Using a doll to demonstrate the procedure
• C. Showing pictures of the hospital environment
• D. Allowing the child to play with medical equipment

Correct answer: B

Rationale: The correct preoperative teaching for a 2-year-old child undergoing surgery involves using a doll to demonstrate the procedure. This method helps the child understand what to expect in a non-threatening and visual way, making the experience less intimidating. Explaining the procedure in simple terms (Choice A) may not effectively convey the details to a young child. Showing pictures of the hospital environment (Choice C) may not directly address the surgical procedure itself. Allowing the child to play with medical equipment (Choice D) can be unsafe and may not effectively prepare the child for the surgery.
