The process by which complex substances are broken down into simple substances is called -
Catabolism
When a patient develops syncope during a
... [Show More] venipuncture, the phlebotomist should first: -
remove the tourniquet and needle and then call for help.
Which substance has a higher concentration in capillary blood than in venous blood? - Glucose
is normally higher in capillary blood compared to venous blood and Potassium, Calcium and
Total Protein are normally lower
If a patient is critical or an antibiotic needs to be given right away, and two blood culture sets
are collected - When more than one set of blood cultures are ordered to be collected at the
same time, the second set should be obtained from a separately prepared site on the opposite
arm if possible
When performing a capillary blood collection, the first blood drop is wiped away because - the
first drop typically has more tissue fluid
Why is it necessary to wipe the first drop of blood away when performing a capillary
procedure? - to eliminate excess tissue fluid;To reduce interstitial fluid contamination
The color-coded tube that is most frequently associated with coagulation tests is - light blue
How far above the venipuncture site should the tourniquet be wrapped around the arm? - 3 to
4 inches
How long should a tourniquet be placed around a patient's arm? - No more than one minute
When is a phlebotomist allowed to perform a venipuncture on an ankle vein? - When all other
options have been exhausted and the physician has given approval
Prior to bandaging the puncture site the phlebotomist should - examine the site for bleeding
During venipuncture, a hematoma may result from which of the following? - Needle bevel is
partially inserted into a vein
Alcohol should be allowed to dry completely prior to skin puncture to - prevent lysis of red
blood cells
When palpating, a vein having which one of the following characteristics would be most
appropriate to select for venipuncture? - Bouncy
Following venipuncture, which of the following should be applied to the venipuncture site? -
Clean, sterile gauze pad
What is the preferred method for infant blood collection? - Capillary
Which of the following actions could cause the formation of a hematoma? - The needle
penetrates all the way through the vein
what is the most critically affected analyte in a hemolyzed specimen - Potassium
The heel is the recommended site for collection of capillary puncture specimens on infants and
the phlebotomist is going to stick in the posterior curvature of the heel. Is this correct? - No the
medial plantar surface of the heel is the best site to prevent possible bone damage
You have properly prepared the antecubital venipuncture site, you have the corrrect collection
device and enter the vein at a 20 degree angle. Is this the proper angle of insertion? - No, 30
degrees is the correct angle for the needle to be inserted into the skin
If blood begins to flow and then stops when an evacuated tube is pushed into the needle the
most likely cause is the - bevel of the needle resting against the vein wall.

Petechiae are tiny, nonraised red spots on a patient's skin when the tourniquet is applied. This
indicates, that - Petechiae, the tiny red spots, are minute drops of blood that escapes from the
capillaries and comes to the surface of the skin below the tourniquet and indicate that the
venipuncture site may bleed excessively [Show Less]
