ASPT Patient Preparation 4

Question 1

A phlebotomist is asked to collect a fasting specimen from a patient who says they ate a small snack 2 hours ago. What is the best course of action?

Accepted Answer

Collect the specimen and note 'non-fasting' on the requisition

Answer

If a non-fasting specimen must be collected, the phlebotomist should document the patient's actual fasting status on the requisition so the provider can interpret results appropriately.

Question 2

What should the phlebotomist verify before performing a venipuncture on an unconscious patient?

Accepted Answer

Identification via wristband and an order for the draw

Answer

For unconscious patients who cannot provide verbal consent or self-identify, identity is confirmed using the wristband, and a valid order must be present before proceeding.

Question 3

Which factor most commonly causes pre-analytical error related to patient preparation?

Accepted Answer

Patient not following fasting or medication instructions before the draw

Answer

Non-compliance with pre-collection instructions (fasting, medication timing, exercise restriction) is the leading pre-analytical variable affecting specimen quality.

Question 4

Before a glucose tolerance test (GTT), the patient must be instructed to:

Accepted Answer

Fast for 8-12 hours and avoid strenuous exercise before the test

Answer

A proper GTT requires 8-12 hours of fasting with avoidance of strenuous exercise, as both food and exercise significantly alter glucose metabolism.

Question 5

A patient who is breast-feeding asks if it matters for a prolactin blood test. The correct response is:

Accepted Answer

Breast-feeding and recent nursing can significantly elevate prolactin; the physician should be informed

Answer

Breast-feeding and nipple stimulation cause acute prolactin surges, so the ordering physician must know the patient's status to interpret the result correctly.
