Answer:
Options, B, C, and E; abdomen, thighs, and arms
Explanation:
All five of these locations can be used for a patient of average build as subcutaneous injection sites, and site selection can depend on various factors, including the type of medication, amount of medication, and the patient's pain sensitivity. They can also be selected using personal preference (both that of the patient or other assistive personnel educated on administered subcutaneous injections) as long as injection sites are being rotated.
The most common sites for subcutaneous (subcut, subq) injections, though, are the abdomen, thighs, and posterior arm. This is because there is a lower likelihood of puncturing muscle, blood vessels, and bone at these locations, and a high likelihood of there being plentiful adipose tissue in which the medication can be administered.
In this case, options B, C, and E would be the correct choices. But, once more, all of these sites are viable.
