Peripheral Intravascular device indications are? - Answer-1. Indicated for patients with adequate venous availability for indicated infusion therapy.

  1. Non-vesicants and non-irritants
  2. PH 5-
  3. Solutions with an osmolality less than 600 mOsm/L. Power-injectable catheters are made of - Answer-poyurethane Power-injectable catheters are engineered to withstand how much pressure? - Answer-a power injection of greater than 300 pounds per square inch, PSI Power-injectable catheters used for injection of what? - Answer-power injection of IV contrast during a computerized tomography (CT) or magnetic resonance imaging (MRI) scan. PICC's with antimicrobial properties may benefit patient with? - Answer-septicemia or neutropenia Tunneled CVAD is used with patients with acute leukemia and other blood cancers going through? - Answer-bone marrow transplant With chemotherapy a CVAD is required for - Answer-1. Long term greater than 3 months treatment.
  4. complex multi-agent protocols
  5. vesicant infusions greater than one hour in duration
  6. continuous chemotherapy infusions 24 to 96 hours in duration. Because of long duration of treatment most adult patients have what type of device rather than a PICC?
  • Answer-Implanted port
  1. this reflects the amount of oxygen left over after the tissues remove what they need
  2. indicates the body taking more oxygen than normal, which is the bodies way to meet tissue oxygen needs when the amount reaching the tissues is less than needed. What does mixed venous oxygen saturation (SvO2) tell us? - Answer-1. whether the cardiac output and oxygen delivery is high enough to meet a patient's needs.
  3. useful if measured before and after changes to cardiac medications or mechanical ventilation. What is a normal SvO2? - Answer-1. 60-80% What is the normal ScvO2 which is from an internal jugular or subclavian vein? - Answer-Normal ScvO from IJ or subclavian vein is greater than 70%. Four fundamental causes for a drop in SvO2: - Answer-1. The cardiac output is not high enough to meet tissue oxygen needs.
  4. The hemoglobin is too low.
  5. The Sao2 (oxygen saturation) is too low
  6. The oxygen consumption has increased

without an increase in oxygen delivery. What is a contraindication of a vascular access device related to axillary lymph node dissection? - Answer-Axillary lymph node dissection including sentinel lymph node biopsy can result in lymph-edema risk for years or decades after the original lymph node dissection surgery. Risk increase when 1 or more lymph nodes are removed. SVC stenosis impacting the ability to advance a catheter may be caused by: - Answer-1. Injury or surgery to SVC.

  1. Prior radiation
  2. History or presence of SVC syndrome
  3. Stenosis of manor upper thoracic vessels. What vein may be most appropriate in a morbid obese patient? - Answer-Due to the location, a PICC inserted in the basilic or brachial may lead to a moist insertion site or catheter dislodgement. The cephalic vein may be most appropriate. Ultrasound appearance of a target vein that changes in size for large to small and back again as it traverses up the arm may represent? - Answer-1. Venous dilatation from a distal stenosis or occulsion.
  4. Do not assume that a CVAD will advance to the desired tip location. The goal of sterile technique to prevent microbial contamination is? - Answer-To protect the patient from getting a hospital acquired infection. Maximal Sterile Barrier Precautions (MSBP) includes: - Answer-cap, mask (on inserter), sterile gown, sterile gloves, total body drape. Mask on all personnel in the room during procedure.
