Answer-Chlorhexidine gluconate
The main reason not to use expired evacuated tubes for blood specimen collection is ✔Correct
Answer-they may exhibit incomplete filling.
Older patients are more prone to hematoma formation because ✔Correct Answer-their veins have
decreased elasticity.

To prevent glycolysis, which additive is used? ✔Correct Answer-Sodium Fluoride
, When blood is inoculated into blood culture bottles using a butterfly apparatus the ✔Correct
Answer-aerobic bottle in inoculated first.
Which of the following conditions would be most likely cause hemoconcentration? ✔Correct
Answer-Dehydration
A collapsed vein will cause a ✔Correct Answer-cessation of blood flow
If a vein feels hard and thready like when palpated, then this vein may be ✔Correct Answer-
sclerosed.
Blood smears made from EDTA specimens must be prepared within what period of time? ✔Correct

Answer-No the tourniquet should be released first before the gauze pad is place over the puncture
site
When performing a heel puncture on an infant, proper technique includes ✔Correct Answer-
placing the lancet flat against the skin on the medial or lateral plantar surface of the heel.
To avoid contamination when should the needle cap be removed? ✔Correct Answer-Just prior to
performing the puncture
When a patient states that he or she has a needle phobia, the phlebotomist should ✔Correct
Answer-have the patient lie down during the procedure
Specimens are scheduled for collection at specific times for different reasons including: ✔Correct
Answer-Measuring the body's metabolism of the test substance, To determine blood levels of
medications prior to next dose, and when Patients must be tested 2 hours before meals.
If additive contamination occurred from an EDTA evacuated tube, what test would potentially be
affected? ✔Correct Answer-Potassium Level
Petechiae are tiny, nonraised red spots on a patient's skin when the tourniquet is applied. This
indicates, that ✔Correct Answer-site may bleed excessively
