A client is newly diagnosed with type 2 diabetes mellitus. The nurse is educating the client about self monitoring blood glucose (SMBG) and hemoglobin A1C (HbA1C). Which statement by the client indicates teaching has been effective?

A. "I will use a lancing device on the center of my finger pad for a drop of blood.": Finger-stick blood glucose testing should be performed on the side of the fingertip rather than the center of the finger pad. The center contains a higher density of nerve endings and pressure receptors, making puncture more painful and potentially interfering with tactile function. B. "I will document my HbA1C results from the SMBG monitor every morning.": Hemoglobin A1C is not measured by standard home glucose monitors. SMBG devices measure capillary blood glucose levels at specific times during the day, whereas HbA1C is a laboratory test reflecting the average blood glucose level over the previous 2 to 3 months. C. "I will inform the healthcare provider (HCP) of my average HbA1C results weekly.": HbA1C testing is typically performed every 3 months in clients with diabetes to evaluate long-term glycemic control. Weekly reporting is not appropriate because HbA1C changes gradually as hemoglobin becomes glycated over the lifespan of red blood cells. D. "I will wash my hands with warm soapy water before sticking my finger.": Proper hand hygiene before SMBG is essential to ensure accurate readings. Washing with warm water and soap removes glucose-containing substances from the skin that could falsely elevate results. Warm water also increases peripheral circulation, helping obtain an adequate drop of blood.
