A client is prescribed 10 units of regular insulin subcutaneously. The nurse draws up the insulin and prepares to administer it. Which site is most appropriate for rapid absorption of regular insulin?
- AThigh
- BDeltoid muscle
- CAbdomen
- DButtocks
Show answer & explanationAnswer & explanation
Correct answer: C. Abdomen
The abdomen provides the most rapid and consistent absorption of insulin due to its rich blood supply and subcutaneous fat. Rapid absorption is often desired for regular insulin, especially when given before meals.
Why the other options are wrong
- A. The thigh provides slower absorption compared to the abdomen.
- B. The deltoid is an intramuscular site, not appropriate for subcutaneous insulin administration.
- D. The buttocks provide slower absorption compared to the abdomen.
Insulin Absorption Sites
Different subcutaneous injection sites for insulin offer varying rates of absorption, with the abdomen providing the fastest and most consistent absorption.
- Abdomen: Fastest absorption.
- Arms (posterior upper): Intermediate absorption.
- Thighs (anterior): Slower absorption.
- Buttocks: Slowest absorption.
- Rotate sites within an area to prevent lipodystrophy.
Memory trick: Always Be The Best for insulin absorption: Abdomen, Back of arms, Thighs, Buttocks.
