A nurse is using a glucometer to measure a client's capillary blood glucose level. Which of the following actions should the nurse take?

Choice A Reason: Select the central tip of a finger is incorrect. The nurse should select a puncture site on the side of the finger, slightly off-center from the central tip, as it tends to be less painful. The side of the finger has an adequate blood supply and can provide an accurate blood sample without causing excessive discomfort. Choice B Reason: Wearing sterile gloves is incorrect. Sterile gloves are not typically necessary for routine capillary blood glucose monitoring. However, clean hands and proper hand hygiene are essential. The nurse should perform hand hygiene before the procedure. Choice C Reason: Keeping the finger in a dependent position is correct. Keeping the finger in a dependent position (hanging down) can promote blood flow and make it easier to obtain a blood sample. This is a recommended technique to facilitate the puncture and collection of blood. Choice D Reason: Milking may hemolyze specimen and introduce excess tissue fluid.
