• Provides guidelines for use of a tunneled CVC - ANSWER- a.

Provides guidelines for use of a new AV fistula

During cannulation of all AV fistulas

• A tourniquet is to be applied to increase vein engorgement and

stabilize vessel

• A tourniquet may be applied to increase vein engorgement if deemed

necessary by the cannulator

• A tourniquet to increase vein engorgement is not necessary if the AVF

is well developed

• The supine position increases pressure within central veins and

diminishes the risk of an air embolism - ANSWER- d. The supine position increases pressure within central veins and diminishes the risk of an air embolism
