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.”
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.

Correct Answer is A
Explanation
A. Listen to the patient, answer questions, and offer to have the supervisor or physician speak with the patient. Understanding the patient’s concerns and providing information may help address their reasons for leaving and promote informed decision-making. Involving the supervisor or physician allows for further discussion.
B. Call both the supervisor and a family member to try to get the patient to reconsider: Family involvement should only occur with the patient’s consent.
C. Obtain a written explanation of the reasons from the patient: This can be done after addressing the patient’s concerns.
D. Advise the patient that insurance may not pay for this hospitalization: This may seem coercive and is not an immediate priority.
Correct Answer is B
Explanation
A. Obtain meals: This is important but not a safety priority.
B. Call the nurse. Ensuring the patient knows how to call for help is a safety priority and essential to their care.
C. Use the telephone: While communication is helpful, it is secondary to patient safety.
D. Work the TV: This is a comfort measure, not a critical concern during orientation.
