Rotation sites for insulin injection should be separated from one another by 2.5 cm (1 inch) and should be used only every:
A. Third day
B. Every other day
C. 1-2 weeks
D. 2-4 weeks
Correct Answer: C. 1-2 weeks
Rotation of sites for insulin injection should be done every week or two. Frequently using the same spot over time can cause fat cells to break down or build up (lipodystrophy) causing lumps under the skin and may interfere with insulin absorption.
Option A: Avoid injecting into the same site over and over. This can irritate the skin and underlying fatty tissue. When rotating injections, move around within the area to ensure that the injection does not always take place in exactly the same spot.
Option B: Puncturing the same point every time can lead to hard lumps or fatty deposits developing. This can be uncomfortable and even reduce the body’s effectiveness in absorbing the medication.
Option D: If a person always administers a morning dose of rapid-acting insulin into their abdomen, they should alternate between different areas of the abdomen to avoid repeated injections into the same site.
