Question

Waiting only 5 seconds between lowering the blood pump speed and drawing the post treatment blood sample would:

A) Yield an inaccurate sample due to insufficient time for blood stabilization.
B) Enhance the accuracy of the sample by minimizing clotting risks.
C) Have no impact on the quality of the sample collected.
D) Facilitate a more reliable assessment of treatment effectiveness.

Answer 1

Waiting only 5 seconds before drawing a blood sample after lowering the blood pump speed results in inaccuracies due to the lack of time for blood stabilization.

Step-by-step explanation:

Waiting only 5 seconds between lowering the blood pump speed and drawing the post-treatment blood sample would yield an inaccurate sample due to insufficient time for blood stabilization. This short interval does not allow enough time for the blood to equilibrate, which can lead to erroneous concentrations of cellular components and metabolites, potentially impacting the assessment of the patient's condition or the effectiveness of the treatment. To obtain an accurate blood sample for analysis, it is crucial to allow a short period after altering the blood flow or pump speed for the blood parameters to stabilize, usually on the order of a few minutes.
