A nurse is reviewing the complete blood count results for a 4-year-old child who is receiving treatment for acute lymphoblastic leukemia. Which of the following findings should indicate to the nurse that the treatment is having a therapeutic effect?
Hemoglobin 6.8 g/dL (9.5 to 14 g/dL)
Platelet count 98,000/mm3 (150,000 to 400,000/mm3)
RBC count 5/mm3 (4 to 5.5/mm3)
WBC count 15,000/mm3 (5,000 to 10,000/mm3)
The Correct Answer is C
A. A low hemoglobin level indicates anemia, which is common in leukemia but does not necessarily indicate treatment effectiveness.
B. A low platelet count is a sign of bone marrow suppression, which is a common side effect of chemotherapy for leukemia.
C. A normal RBC count indicates that the child's bone marrow is producing enough red blood cells to carry oxygen throughout the body.
D. Elevated WBC count is typical in leukemia and does not necessarily indicate treatment effectiveness.

Correct Answer is ["12.5"]
Explanation
To answer this question, we need to perform some calculations. First, we need to convert the child's weight from pounds to kilograms. To do this, we multiply 55 lb by 0.4536 kg/lb, which gives us 24.948 kg. Next, we need to find out how much ibuprofen the child needs in milligrams. To do this, we multiply 10 mg/kg by 24.948 kg, which gives us 249.48 mg. Finally, we need to find out how many milliliters of ibuprofen solution the nurse should administer. To do this, we use the formula:
(mg of ibuprofen) / (mg/mL of ibuprofen solution) = mL of ibuprofen solution
Substituting the values, we get:
(249.48 mg) / (100 mg/5 mL) = 12.474 mL
Rounding to the nearest tenth, the answer is 12.5 mL. Therefore, the nurse should administer 12.5 mL of ibuprofen solution to the child.
