A nurse is reinforcing discharge teaching with a client who has angina and a prescription for sublingual nitroglycerin tablets. Which of the following statements by the client indicates an understanding of the teaching?

A. Keep the finger in a dependent position:

• Keeping the finger in a dependent position (lower than the heart) helps promote blood flow to the fingertips, making it easier to obtain a blood sample. This position can facilitate the formation of a blood drop, improving the chances of obtaining an adequate sample for testing.

B. Wear sterile gloves:

• Sterile gloves are not typically necessary for routine capillary blood glucose monitoring. Clean, non-sterile gloves are generally sufficient for this procedure. However, the nurse should perform proper hand hygiene to minimize the risk of contamination.

C. Select the central tip of a finger:

• The central tip of the finger is more sensitive, and choosing this area may cause greater discomfort for the client. The sides of the fingertips are often preferred for capillary blood glucose testing as they have a good blood supply and are less sensitive.

D. Test the first drop of blood that forms after the puncture:

• The initial drop may contain tissue fluid or contaminants from the puncture site, so it is important to use the first drop to obtain a representative blood sample. This step contributes to the accuracy of the blood glucose measurement.

The correct answer is C. A small, soft-bristled toothbrush is recommended for cleaning a toddler's teeth as it can remove plaque without damaging the gums. The bristles should be angled at 45 degrees, not 90 degrees, to reach under the gum line. A pea-sized amount of toothpaste, not a 5-inch strip, is sufficient for a toddler's toothbrush. Flossing is not necessary until two adjacent teeth touch each other, which usually happens around age 2 or 3.
