A nurse is using a glucometer to measure a client's capillary blood glucose level.

Which of the following actions should the nurse take?

A.

Keep the finger in a dependent position.

B.

Wear sterile gloves.

C.

Select the central tip of a finger

D.

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

Answer and Explanation

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 B

Explanation

B. “I should discuss this document with my family after I sign it.”It is important for clients to discuss their advance directives with their family members to ensure that their wishes are understood and respected. This helps prevent confusion and ensures that family members are aware of the client’s preferences for end-of-life care.

Incorrect Options:

A. “I am not allowed to change my mind once I sign this document.”Clients can change or revoke their advance directives at any time as long as they are competent to do so.

C. “My partner needs to be present when I sign this document.”While it is a good idea to have a witness, it is not necessary for the partner to be present. The requirements for witnesses vary by jurisdiction.

D. “An attorney will need to notarize this document for it to be valid.”Not all advance directives require notarization. The requirements vary by state or country, and some may only require witnesses.

Correct Answer is A

Explanation

The correct answer is A. The client should begin collecting urine after discarding the first morning void, which is not part of the 24-hr period. The client should avoid eating a protein-rich diet during the collection period, as this can affect the creatinine level. The client does not need to cleanse the perineal area with an antiseptic towel each time before voiding, as this is not necessary for a creatinine clearance test. The client does not need to record the blood glucose level each time they void, as this is not related to the creatinine clearance test.
