A nurse is performing blood glucose monitoring on a client. Which of the following actions should the nurse take?

A. Position the client's finger above their heart: The finger should be positioned below the level of the heart to encourage blood flow, making it easier to obtain a sufficient blood sample for testing. Elevating the finger would decrease blood flow and make collection more difficult. B. Apply sterile gloves prior to performing the test: Clean, non-sterile gloves are sufficient for routine blood glucose monitoring. Sterile gloves are not necessary unless performing procedures that require a sterile environment, such as surgery or central line dressing changes. C. Puncture the side of the client's finger: The sides of the fingertips have fewer nerve endings compared to the pads, making the procedure less painful. Additionally, puncturing the side helps promote better blood flow and reduces the risk of bruising and soreness. D. Milk the finger site: Milking or squeezing the finger excessively can cause hemolysis or contamination of the blood sample with tissue fluid, leading to inaccurate glucose readings. Gentle pressure may be used if needed, but forceful milking should be avoided.
