Answer to Question 1

Ans: A
Feedback:
There are four recognized routes for catheter contamination. The most common route of infection is colonization of the catheter tip due to migration of skin organisms from insertion site. Direct contamination of the catheter or catheter hub is also a contributing factor (O'Grady, N.P., et al, 2011). Less common, the catheters may be contaminated by organisms that migrate from infections in other areas of the client. Rarely, the infusion itself may be contaminated. Additionally, the material the catheter is made from may contribute to CRBSI. Silastic catheters are associated with higher risk of catheter infections due to surface irregularities that allow development of a biofilm formation along the catheter's inner lumen.

Answer to Question 2

Ans: A
Feedback:
The infusion can be set on a continuous rate (basal mode) or an intermittent mode controlled by the client (patient-controlled epidural analgesia PCEA). It is commonly used in labor and discontinued after delivery.
