A 12-month-old child has a capillary lead level reading of 15 μg/dL. Based on this finding, the nurse practitioner should:

Rationale: A. A capillary lead level of 15 μg/dL is above the reference level of concern; it is not considered normal, so rescreening in a year is inappropriate. B. Capillary (fingerstick) lead measurements can be affected by contamination and are used for initial screening. Elevated results should always be confirmed with a venous blood sample before taking further action. C. Chelation therapy is reserved for significantly elevated venous lead levels (typically ≥45 μg/dL in children); it is not indicated at this stage without confirmation. D. Home inspection for lead contamination is important if elevated lead levels are confirmed, but the first step after an abnormal capillary reading is to confirm with a venous sample.
