The nurse is teaching a patient who is recovering from issues due to being newly diagnosed as a diabetic to monitor her blood glucose using a glucometer. The nurse will know that the patient is competent in performing her finger-stick to obtain blood when she:

  1. Uses the ball of a finger as the puncture site
  2. Uses the side of a fingertip as the puncture site
  3. Avoids using the fingers of her dominant hand as puncture sites
  4. Avoids using the thumbs as puncture sites
Explanation
Answer - B - Using the side of a fingertip as the puncture site confirms that the client understands the health teaching on blood glucose monitoring using a glucometer. The sides of the fingertips have fewer nerve endings than do the balls of the finger, so less discomfort will result from selecting the sides as puncture sites. Both hands, including the thumbs, can be used as puncture sites.
