RN Nursing Care of Children 2019 With NGN

Correct Answer: C

Rationale: A low-phosphorus diet is important in managing chronic renal failure to prevent hyperphosphatemia and its associated complications, such as bone disease. Protein intake should be controlled but not necessarily low, and vitamin D supplementation is often required, not reduced.

Correct Answer: B

Rationale: A sunken fontanel is a classic sign of dehydration in infants, indicating a fluid volume deficit. In dehydration, the fontanel sinks due to decreased fluid volume in the body. Increased blood pressure (Choice A) is not typically associated with dehydration in infants. Decreased pulse rate (Choice C) is not a common finding in fluid volume deficit, as the body tries to increase the heart rate to compensate for decreased volume. Low urine specific gravity (Choice D) may be seen in dehydration, but it is not as specific or as easily observable as a sunken fontanel.

Correct Answer: A

Rationale: Calcium gluconate, sodium bicarbonate, and glucose with insulin are used as temporary measures to rapidly reduce serum potassium levels. They help shift potassium into cells and stabilize the heart but do not remove potassium from the body like dialysis does.

Correct Answer: C

Rationale: Prednisone, an immunosuppressant, increases the child's susceptibility to infections, making infection prevention a critical nursing goal. Detecting edema and stimulating appetite are important but secondary to preventing potentially life-threatening infections.

Correct Answer: D

Rationale: The correct answer is D. The child is slightly taller than average, but the weight is within normal limits. This information should be reassuring to the parent and provides insights into normal growth patterns. Choice A is incorrect as it inaccurately states that the child is taller than other children this age. Choice B is incorrect because the child's weight is actually within normal limits. Choice C is incorrect as it inaccurately states that the child is shorter in stature than other children this age.
