A nurse is using a glucometer to measure a client's capillary blood glucose level.
Which of the following actions should the nurse take?
Keep the finger in a dependent position.
Wear sterile gloves.
Select the central tip of a finger
Test the first drop of blood that forms after the puncture.
The Correct Answer is A
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.

Correct Answer is A
Explanation
The correct answer is A. Interlace the fingers while rubbing hands together. This is one of the steps of performing a surgical hand scrub, which is an antiseptic surgical scrub or antiseptic hand rub that is performed prior to donning surgical attire. Interlacing the fingers helps to remove microorganisms from the spaces between the fingers and under the nails.
Correct Answer is D
Explanation
The correct answer is D. The nurse should measure the client's vital signs first to assess for any injuries or complications from the fall, such as bleeding, shock, or head trauma. The nurse should then notify the provider and document the fall in the client's medical record. Completing an incident report is also important, but it is not the first action that the nurse should take.
