Answer - D - “When I disconnect the pump overnight, I will use the sterile cap to cover the end of the tubing.” The external insulin pump is a continuous subcutaneous insulin delivery system. It consists of a syringe in the pump attached to a long, thin, narrow-lumen plastic tubing with either a needle or Teflon catheter at the end. The needle/catheter is inserted into the subcutaneous tissue (usually in the abdomen). The syringe, tubing, and site are changed every three days. The pump uses regular buffered insulin. The pump delivers a continual (basal) infusion of insulin and additional low (bolus) doses of insulin are administered by the client at meal times. The pump provides flexibility for the client. The pump is worn continuously and is not disconnected for more than one hour at a time. Most pumps are now waterproof and can be worn during showers, swimming, etc.
