This test requires strict skin antisepsis procedures before specimen collection?
blood cultures
The tests performed in this department are typically collected in a tube with a light-blue stopper
Coagulation Department
Capillary puncture blood most closely resembles this
arterial blood
A laboratory report form should always indicate the fact that a specimen has been collected by capillary puncture because of this
test results can vary depending on the method of collection
The term “calcaneus” refers to this body part
heel bone
Hormone detected in a positive urine pregnancy test
HCG
This tube additive is responsible for the most carryover problems
ethylenediaminetetraacetic acid (EDTA)
It is necessary to control depth of lancet insertion during capillary puncture to avoid this
injuring the heel bone
This causes a microhematocrit tube to fill with blood
capillary action
The term "basal state" is defined as this
The resting metabolic state of the body early in the morning after fasting for a minimum of 12 hours
Creatinine clearance tests this bodily system
the urinary system
the proper blood-to-additive ratio for a light-tube collected for a coagulation test (such as prothrombin)
9:1 (nine parts blood to one part sodium citrate)
Capillary punctures are not acceptable for this color/additive tube
Light blue/sodium citrate (cannot maintain proper blood to additive ratio)
These are the preferred capillary puncture sites for fingersticks and heelsticks; respectively
middle and ring fingers
medial or lateral plantar surface
The ability of the body to repair and maintain itself to achieve a “steady state” defines this term
homeostasis
A 2-hour postprandial specimen should be drawn
2 hours after the patient finishes eating a meal
Type of additive recommended for collecting an ethanol test specimen
sodium fluoride (gray top tube)
Capillary punctures that are deeper than recommended are more painful because pain fibers increase in abundance below this
2.4mm
Capillary blood gases are less desirable than arterial blood gases (ABGs) because of these factors
Skin puncture blood contains tissue fluid
Skin puncture blood is only partly arterial
The blood is exposed to air during collection
The term “phlebotomy” is derived from Greek words that, literally translated, means this
vein incision
ACT is used to monitor this type of therapy
heparin therapy
A phlebotomist collects a light-blue-top, lavender-top, and gray-top tube from an inpatient.
Respectively, the tubes most likely contain the following additives
sodium citrate (light blue), EDTA (lavender), and sodium fluoride (gray)
Capillary puncture blood reference ranges are higher for this analyte
glucose
Capillary puncture is the preferred method of obtaining blood from infants because of these factors
capillary blood is preferred for some tests
removing tubes of blood can lead to anemia
venipuncture in infants may damage veins
Hemostasis refers to this
the stoppage of bleeding
