How to Inject Insulin Injection: Using Syringe

Insulin administration

Insulin pumps

  • Continuous subcutaneous insulin infusion is administered by an externally worn device that contains a syringe attached to a long, thin, narrow-lumen tube with a needle or Teflon catheter attached to the end.
  • The client inserts the needle or Teflon catheter into the subcutaneous tissue (usually on the abdomen) and secures it with tape or a transparent dressing; the pump is worn on a belt or in a pocket; the needle or Teflon catheter is changed at least every 2 to 3 days.
  • A continuous basal rate of insulin infuses; in addition, based on the blood glucose level, the anticipated food intake, and the activity level, the client delivers a bolus of insulin before each meal.
  • Both rapid-acting and regular insulin (buffered to prevent the precipitation of insulin crystals within the catheter) are appropriate for use in these pumps.



Insulin pump and skin sensor

  • A skin sensor device that monitors the client’s blood glucose continuously; the information is transmitted to the pump, determines the need for insulin, and then the insulin is injected.
  • The pump holds up to a 3-day supply of insulin and can be easily disconnected for activities such as bathing.

Jet injectors

  • A jet injector is a needleless device that delivers insulin through the skin under pressure in an extremely fine stream.
  • Insulin administered by this device usually absorbs faster.
  • The injector can cause bruising at the site of insulin delivery.

Pancreas transplants

  • The goal of pancreatic transplantation is to halt or reverse the complications of diabetes mellitus.
  • Transplantations are performed on a limited number of clients (generally, these are clients who are undergoing kidney transplantation simultaneously).
  • Immunosuppressive therapy is prescribed to prevent and treat rejection.

Self-monitoring of blood glucose level

  • Self-monitoring provides the client with the current blood glucose level and information to maintain good glycemic control.
  • Monitoring requires a finger prick to obtain a drop of blood for testing.
  1. Alternative site testing (obtaining blood from the forearm, upper arm, abdomen, thigh, or calf) is nowavailable using specific measurement devices.
  2. Tests must be used with caution in clients with diabetic neuropathy.
  3. Client instructions

Urine testing

  1. Urine testing for glucose is not a reliable indicator of the blood glucose level and is not used for monitoring purposes.
  2. Instruct the client in the procedure for testing for urine ketones.
