Passage / Scenario
A nurse is obtaining a 2-hr postprandial blood glucose from a patient.Which of the following actions should the nurse take?
Correct answer
D
Rationale
The correct answer is D: Select the lateral side of the finger for puncture. This is the most appropriate action because the lateral side of the finger has fewer nerve endings, making it less painful for the patient. Puncturing this area also minimizes the risk of hitting bone and ensures an adequate blood flow for sampling. Holding the finger above the heart (choice A) is incorrect as it may affect blood flow. Smearing blood onto the reagent strip (choice B) is incorrect as it can lead to inaccurate results. Puncturing the finger while still damp with antiseptic solution (choice C) is incorrect as it can dilute the blood sample.
