A nurse is preparing a child for a lumbar puncture. In which of the following positions should the child be placed for the procedure?

A. This temperature is too high and can cause severe burns. The recommended water heater temperature is 120° F (49° C) or lower.
B. Toddlers are curious and may explore electrical outlets and cords, leading to burns or electrocution. Keeping wires out of sight is essential.
C. Turning pot handles toward the front of the stove increases the risk of a toddler pulling on them, causing spills and burns. Handles should be turned inward.
D. This time frame is when the sun's rays are strongest, increasing the risk of sunburn. Outdoor activities should be scheduled during cooler parts of the day or when the sun is less intense.

A. A hemoglobin level of 6.8 g/dL is lower than the normal range for a child (9.5 to 14 g/dL). This indicates anemia, which is a common issue in leukemia due to the disease affecting red blood cell production. Although this level is concerning, it does not necessarily reflect a therapeutic effect of treatment.
B. A WBC count of 15,000/mm³ is elevated compared to the normal range (5,000 to 10,000/mm³). In the context of ALL, high white blood cell counts can indicate active disease or ineffective treatment. Therapeutic effects are generally indicated by a reduction in WBC count towards the normal range.
C. The RBC count of 5/mm³ is within the normal range for a 4-year-old child (4 to 5.5/mm³). This finding suggests that red blood cell production is relatively stable. However, in the context of leukemia treatment, the focus is often on other indicators such as WBC count and platelet count to assess treatment effectiveness
D. A platelet count of 98,000/mm³ is lower than the normal range (150,000 to 400,000/mm³), indicating thrombocytopenia (low platelet count). In children with leukemia, treatment often aims to normalize platelet counts or at least improve them from very low levels.
