A nurse is evaluating the laboratory results of four clients. The nurse should report which of the following laboratory results to the provider?

A. A client who has a prescription for heparin and an aPTT of 90 seconds (30-40 seconds).: This is significantly elevated and indicates a risk for bleeding, as the therapeutic range for heparin is typically 1.5–2.5 times the normal value. B. A client who has a prescription for warfarin and an INR of 2.0 (0.8 to 1.1): This is within the therapeutic range for most conditions treated with warfarin (e.g., 2.0–3.0). C. A client who has a prescription for heparin and an aPTT of 65 seconds (30-40 seconds): This is slightly elevated but still within the therapeutic range for heparin (typically 60–80 seconds). D. A client who has a prescription for warfarin and an INR of 3.0 (0.8 to 1.1): This is within the therapeutic range for most warfarin indications.
