A primiparous woman presents in labor with the following labs: hemoglobin 10.9 g/dL (109 g/L), hematocrit 29% (0.29), hepatitis surface antigen positive, group B Streptococcus positive, and rubella non- immune. Which intervention should the nurse implement? Reference Range Hemaglobin [Reference Range:12-16 g/dL (120-160 g/L)] Hematrocrit [Reference Range:Pregnant female: 37% to 47% (0.37 to 0.47 volume fraction)] Hepatitis Surface Antigen [Reference Range: negative] Group B Streptococcus [Reference Range: negative]

The client's labs indicate that she has a positive result for group B Streptococcus (GBS) and hepatitis surface antigen, and she is also identified as rubella non-immune. Ampicillin is the recommended antibiotic for intrapartum prophylaxis against GBS infection to reduce the risk of transmission to the newborn. Administering ampicillin intravenously would help protect the newborn from potential GBS-related complications. Transfusion of packed red blood cells is not indicated based on the hemoglobin and hematocrit values provided. The client's hemoglobin and hematocrit levels, although lower than the reference range, are not critically low and do not necessarily require a blood transfusion. Injecting hepatitis B immune globulin is not the appropriate intervention in this case. The client is positive for hepatitis surface antigen, indicating active infection, and requires appropriate medical management, which may include antiviral treatment. Administering the measles, mumps, rubella vaccine is contraindicated during pregnancy. Vaccination for rubella is typically recommended prior to conception or postpartum to prevent congenital rubella syndrome.
