Pediatric ATI Practice Exam

Which lab value should a nurse report for a 6-year-old receiving chemotherapy?

1. WBC 4,500 cells/uL

2. Hgb 8.5 g/dL

3. Platelets 250,000 cells/uL

4. Hct 35%

The correct answer is: Hgb 8.5 g/dL

For a 6-year-old child undergoing chemotherapy, a hemoglobin level of 8.5 g/dL is concerning and should be reported. Chemotherapy can lead to a decrease in red blood cells due to its effects on the bone marrow, where blood cells are produced. Normal hemoglobin levels for a child in this age range typically fall between 11.5 g/dL and 13.5 g/dL. A level of 8.5 g/dL indicates anemia, which can lead to symptoms such as fatigue, weakness, and increased susceptibility to infections. Therefore, identifying and reporting this abnormality is crucial for the child's safety and may warrant intervention, such as a blood transfusion or further investigation into the cause of the anemia. In this context, the other lab values do not indicate immediate concern. A white blood cell count of 4,500 cells/uL is within the normal range, suggesting that the child does not have leukopenia, which is often a side effect of chemotherapy. A platelet count of 250,000 cells/uL demonstrates adequate platelet levels, indicating that the child does not currently have thrombocytopenia, which would elevate the risk of bleeding. Similarly, a hematocrit level of 35
