Question

Quizplus · Accepted Answer

Wasting the first drop of blood obtained from the patient's finger ensures that the sample is not contaminated with tissue fluids or debris, which can result in inaccurate readings. Cleaning the finger with alcohol prior to pricking it with a lancet is appropriate to disinfect the area. Asking the patient to hold his hand above his head prior to pricking a finger for blood has no impact on the accuracy of the reading. Using a lancet to prick an artery or vein for the blood sample is not appropriate, as it can cause significant bleeding and harm to the patient.
