Pre-Analytical Consideration Part B Flashcards
avoid these areas since it’s difficult to palpate or penetrate in burned
and scarred areas.
o painful
o susceptible to infection
→ healed sites with extensive scarring may have impaired circulation that
could lead to erroneous (invalid or false) test results
Burns, Scars and Tattoos
may feel hard and cordlike and lack of resiliency since they are partially or completely occluded (obstructed)
Damaged Veins
Veins may be:
- Sclerosed (hardened)
- Thrombosed (clotted)
Effects of inflammation, disease, or chemotherapy drugs
Thrombosed (clotted)
Swelling caused by abdominal accumulation of fluid in tissue
Edema
What is the common problem after mastectomy
Edema
yield inaccurate test results owing to contamination by swelling
▪ harder to locate
▪ fragile
▪ easily injured by tourniquet & antiseptic
▪ healing may be prolonged
Edema
Swelling or mass of blood (often clotted)
Hematoma
o can be caused by blood leaking from a blood vessel
o large bruise spread around the area
o Hemolyzed blood will occur when puncturing to hematoma
site
▪ painful
▪ can coagulation and lead to inaccurate test
Hematoma
Surgical Breast Removal
Mastectomy
- never drawn blood from an arm on the same side
o Lymph node removal
▪ part of the procedure
Mastectomy
May case Lymphocytosis
Mastectomy
o Obstruction or stoppage of normal lymph flow
o could change blood composition
o lead to inaccurate test results
Lymphocytosis
it’s an impaired lymph flow makes the arm susceptible to
swelling
Lymphedema
- Extremely Overweight
Obesity
18 inch long
Strap Tourniquet
Designed for obese
Bariatric Tourniquets
used and just below the patient’s diastolic pressure
Bariatric or XL size blood pressure cuff
What are the steps to locate obese vain
–> 1st check antecubital area
→ next palpable is median cubital vein
→ then ask the patient where or what sites have been successful for past blood draws
→ next option: cephalic vein
o to locate: rotate the patient’s arm medially
- Loss of muscle function
- Can be temporary or permanent
- Can be localized in one area or widespread
Paralysis

What is the meaning of VADS
Vascular Access Devices and Sites
→ tubing devices that are designed to allow entry to veins or arteries
→ for patients who require frequent venous or arterial access
→ commonly used for administration of meds, fluids, blood products & sometimes blood collection
→ General Rule: do not performed in extremity with VAD
Vascular Access Devices and Sites (VADS)
What is the meaning of IV?
Intravenous Line
→ “Pertaining to or within the vein”
→ quick way to deliver fluids, meds, blood transfusion products and other substances
Intravenous Line (IV)
o catheter inserted in peripheral vein
▪ its typically connected to a line that is used to administer fluid
o line is attached to a bag containing the substance being
administered
Intravenous Line (IV)
Line is usually having a special drip chamber that prevents air from entering the tubing allows the flow rate to be estimated and controlled
IV Drip
If the patient has an IV in both arms, draw ____ the IV
