A patient asks why the blood glucose meter directions state to wipe away the first drop of blood. The most informative response by the nurse would be:

“The first drop has serous fluid that can dilute the specimen.”

“The first drop is usually contaminated.”

“This eliminates microorganisms from the sample.”

“The first drop is usually too small.”

Answer and Explanation

The Correct Answer is A

A. "The first drop has serous fluid that can dilute the specimen." The first drop of blood may be mixed with serous fluid or tissue fluid, which can lead to inaccurate glucose readings.

B. "The first drop is usually contaminated.": This is inaccurate; contamination is not the primary concern.

C. "This eliminates microorganisms from the sample.": Blood glucose meters are not designed to detect or be affected by microorganisms.

D. "The first drop is usually too small.": The amount of blood is not the issue; it is the potential for dilution.
