Patients who are obese have veins that are:
Deep and difficult to locate
A solution to puncturing obese patients is to
Use a longer tourniquet or locating the cephalic or cubital vein
There are cases when _____ are needed do blood sampling, infusing medication, central venous pressure reading. and blood transfusion of a patient.
vascular access devices (VADs)
Choosing ____ is based On the needs of the patient, the purpose, and the length of time the device is to remain in the body.
vascular access sites
What are the VADS used in phlebotomy?
- Arterial Line
- Arteriovenous Shunt or Fistula
- Blood-sampling Device
- Heparin or Saline Lock
- Intravenous (IV) Sites
- Central Vascular Access Devices (CVADs)
