QMA Insulin Types and Administration Techniques 3

Question 1

Rapid-acting insulin analogs such as lispro, aspart, and glulisine are typically administered:

Accepted Answer

0–15 minutes before or immediately after meals

Answer

Rapid-acting analogs have a quick onset (5–15 minutes) and are given just before or right after eating to match the postprandial glucose rise.

Question 2

Which site of insulin injection generally produces the fastest absorption rate?

Accepted Answer

Abdomen

Answer

The abdomen has the fastest insulin absorption rate due to greater subcutaneous blood flow in that area.

Question 3

A resident who uses an insulin pen leaves the needle attached after injection. The QMA should explain that this can cause:

Accepted Answer

Insulin leakage or air entering the cartridge

Answer

Leaving a needle attached allows insulin to leak out or air to enter the cartridge, affecting subsequent dose accuracy.

Question 4

What is the recommended maximum volume for a single subcutaneous insulin injection at one site?

Accepted Answer

1 mL

Answer

No more than 1 mL should be injected at a single subcutaneous site to minimize discomfort and ensure proper absorption.

Question 5

Lipohypertrophy at injection sites is most commonly caused by:

Accepted Answer

Repeatedly injecting into the same small area

Answer

Lipohypertrophy (fatty tissue buildup) results from injecting repeatedly into the same spot, which can cause erratic insulin absorption.
