ulol
_______________ is swelling caused by the abnormal accumulation of fluid in the tissues.
Edema
Reasons why specimens collected from edematous areas are avoided:
- May yield inaccurate test results owing to contamination with tissue fluid or
altered blood composition caused by the swelling. - Veins are harder to locate and are often fragile and easily injured by
tourniquet and antiseptic application - Healing may be prolonged in these areas
Reasons why specimens collected from bruised (with hematoma) areas are avoided:
- The site is painful
- The site may be contaminated with hemolyzed blood from outside the vein
(NOTE: never use hemolyzed blood sample for testing as it would lead to
erroneous results) - Obstruction of blood flow may occur as the effects of the clotting process
may also lead to inaccurate test results.
A ____________ is a swelling or mass of blood (often clotted) that can be caused by blood leaking from a blood vessel during or following venipuncture.
hematoma
_____________ is the first step to a successful venipuncture.
Proper tourniquet selection and application
A ________ may be used to support the location of the vein making it more prominent.
blood pressure cuff
T or F
Blood should be drawn from an arm on the same side as a mastectomy
Blood should never be drawn
Impaired lymph flow makes the arm susceptible to swelling, called, _________ and to infection.
lymphedema,
An ________________ is a catheter that is placed in an artery.
arterial line (A-line or Art-line)
An arterial line is a catheter that is placed in an artery. It is most commonly placed in a _______________
radial artery
is typically used to provide accurate and continuous measurement of a patient’s blood pressure.
ARTERIAL LINE
It may also be used to collect blood gas and other blood specimens and for the administration of drugs such as dopamine.
ARTERIAL LINE
T or F
Only specially trained personnel should access arterial lines.
T
These devices are permanent surgical connection of an artery and vein by direct infusion resulting in a bulging vein, or with a piece of vein or tubing that creates a loop under the skin.
ARTERIOVENOUS SHUNT, FISTULA, OR GRAFT
It is typically created to be used for dialysis, commonly joins the radial artery
and cephalic vein above the wrist on the underside of the arm.
ARTERIOVENOUS SHUNT, FISTULA, OR GRAFT
This is a catheter or cannula connected to a stopcock or a cap with a diaphragm (thin rubber-like cover) that provides access for administering medication or drawing blood.
HEPARIN or SALINE LOCK
