Rationale: This practice, known as "coining," is a cultural method believed to rid the body of illness and is not indicative of child abuse.

Correct Answer: D

Rationale: A high white blood cell count (leukocytes of 275,000/mcL) at diagnosis is associated with a worse prognosis in leukemia because it indicates a more aggressive disease with a higher tumor burden. Slow response to chemotherapy (choice A) is a consequence of the aggressive disease and not a determining factor at diagnosis. Platelets of 150,000/mcL (choice B) and leukocytes less than 10,000/mcL (choice C) are within normal ranges and not indicative of a worse prognosis in leukemia.

Correct Answer: C

Rationale: The correct answer is C: Acute renal failure in children is often reversible, especially when the underlying cause is identified and treated promptly. It does not always lead to chronic renal failure or the need for a kidney transplant. Choice A is incorrect as prophylactic antibiotics for life are not a standard treatment for acute renal failure. Choice B is incorrect as acute renal failure does not always progress to chronic renal failure. Choice D is incorrect as not all children with acute renal failure will eventually require a kidney transplant.

Correct Answer: C

Rationale: For a conscious child with mild hypoglycemia, giving 15 grams of fast-acting carbohydrates is the appropriate intervention. This can quickly raise blood glucose levels to prevent further complications. Administering insulin (Choice A) would further lower the glucose level, which is not suitable in this scenario. Administering epinephrine (Choice B) is not indicated for hypoglycemia. Glucagon (Choice D) is used for severe hypoglycemia with altered consciousness, not for mild cases where the child is awake and alert.
