Question

in which of the following locations can insulin be injected?
abdomen
wrist
upper chest
upper back

Explanation:

Insulin is typically injected into areas with a layer of fat and relatively few nerves and blood vessels close to the surface. The abdomen is a common and recommended site for insulin injection as it has a good fat layer, allows for consistent absorption, and is easy to access. The wrist has very little fat and many nerves/blood vessels, making it unsuitable. The upper chest and upper back can be used but the abdomen is a more standard and common primary site among these options.

Answer:

A. Abdomen
