A nurse is reviewing the laboratory results for a client who is at 32 weeks of gestation. For which of the following results should the nurse notify the provider?

A. Hgb 12 g/dL: Hemoglobin at 12 g/dL is within the expected range for a healthy pregnant client in the third trimester. Normal pregnancy ranges typically decrease slightly due to hemodilution, and this value does not indicate a need for provider notification. B. Platelet count 90,000/mm³: A platelet count below 100,000/mm³ (thrombocytopenia) is concerning during pregnancy and may indicate gestational thrombocytopenia, preeclampsia, or other hematologic disorders. This finding requires prompt provider notification for evaluation and potential intervention. C. Hematocrit 37%: Hematocrit of 37% falls within normal limits for a pregnant client and does not indicate anemia or other abnormal findings. Routine monitoring is sufficient. D. Creatinine 0.7 mg/dL: Creatinine is within the expected range for pregnancy, which is typically slightly lower than in nonpregnant adults due to increased renal clearance. This result does not warrant urgent provider notification.
