Correct Answer: C

Rationale: The correct answer is C, the Supplemental Food Program for Women, Infants, and Children (WIC). WIC provides nutritional assistance to low-income pregnant women, breastfeeding women, and children under 5. The Division of Maternal and Child Health (Choice A) focuses on promoting the health of mothers and children but does not provide direct nutritional assistance. Medicaid (Choice B) is a health insurance program for low-income individuals but does not specifically address nutritional needs. The State Children's Health Insurance Program (Choice D) provides health insurance for children in low-income families but does not offer nutritional support like WIC does.

Correct Answer: A

Rationale: The correct answer is A: Petechiae, fever, fatigue. Children with leukemia commonly present with petechiae (due to low platelet count), fever (due to infection), and fatigue (due to anemia), which are classic manifestations of the disease. Option B is incorrect because headache, papilledema, and irritability are more indicative of increased intracranial pressure, not leukemia. Option C is incorrect as muscle wasting and weight loss are not typical initial manifestations of leukemia in children. Option D is incorrect as decreased intracranial pressure, psychosis, and confusion are not commonly associated with leukemia.
