What is blood collected from capillary puncture composed of? - ✔✔✔
Correct Answer > blood from capillaries, arterioles, veins, and
tissue fluid
Which samples must be sent to lab immediately - ✔✔✔ Correct
Answer > Blood and Urine
- increase the chance of pathogen detection
Goggles - ✔✔✔ Correct Answer > - although not commonly used,
goggles are frequently recommended for use
- protect eyes from exposure due to splashing of blood-borne
pathogens
Antiseptic - ✔✔✔ Correct Answer > - antimicrobial substances
used to clean puncture sites before procedure in order to reduce the
risk of possible infection
- most common antiseptic is alcohol
,How long should serum specimens be sent to lab - ✔✔✔ Correct
Answer > within 2 hours
Allergic Reaction - ✔✔✔ Correct Answer > - some patients may be
allergic to supplies used during puncture, such as latex gloves
- patient records should always be checked for known allergies
- if patient has allergic reactions that were unknown, be prepared to
provide or call for medical attention
Blood Smear - ✔✔✔ Correct Answer > performed right after wiping
away the first drop of blood
A spreader (two glass slide) is positions and a small drop of blood is
placed on the slide. The top glass is pulled back into the blood drop to
spread it along the back side of the glass. The slide is then pushed left
quickly
What is the best angle for blood smear spreading - ✔✔✔ Correct
Answer > 30 degrees
Arterial Puncture - ✔✔✔ Correct Answer > usually performed for
further analysis of blood gas
Should be done with no exposure to air
,Why should arterial pressure not be done in exposure to air - ✔✔✔
Correct Answer > to prevent the escape of gas from the liquid
At what angle should artery be punctured - ✔✔✔ Correct Answer >
90 degreed
Gloves - ✔✔✔ Correct Answer > - disposable gloves used in
phlebotomy to help prevent contamination - can be made of latex,
nitrile rubber, neoprene, or vinyl
- there are two types of gloves: exam gloves and surgical gloves
- surgical gloves are better sized and made to a higher standard
Tourniquet - ✔✔✔ Correct Answer > - compressing device that is
used to control blood circulation
- usually resembling a rubber tube, it is wrapped around the arm during
the
procedure
- more modern devices are available with contour cuffs attached to
wire
Collection Tube - ✔✔✔ Correct Answer > - made of glass or plastic
(plastic being preferred in use)
- tubes are attached to a needle and a hub
, - tubes contain vacuum so that they fill automatically to a certain level -
some tubes contain anticoagulants (additives)
- anticoagulants are substances that prevent blood clotting
- in tubes with anticoagulants, it is important to fill the tube with the
correct amount of blood to provide an accurate blood-additive ratio
Heparin - ✔✔✔ Correct Answer > preferred in clinical chemistry
Lithium Heparin - ✔✔✔ Correct Answer > preferred to study glucose
levels
Acid Citrate dextrose - ✔✔✔ Correct Answer > used in blood
donations
Syringe - ✔✔✔ Correct Answer > - medical syringes are usually
fitted with needles
- consists of a plunger and a tube (plunger fits exactly into tube)
- design makes it possible for fluid to be pulled in and pushed out of the
syringe
Needles - ✔✔✔ Correct Answer > needle sizes vary, as do the
gauges (openings) of needles
- larger gauge sizes refer to smaller openings (diameters) of needles
- the butterfly needle refers to a winged needle (infusion) set
