单项选择题
The nurse preparing to give a child an intramuscular injection chooses to give the injection into the gluteal muscle. The site is acceptable because which of the following reasons
A. The child has been walking for 1 year.
B. The child has small deltoid muscles.
C. The child is older than 2 years.
D. The child weighs more than 25 pounds.
答案
参考答案：A
解析：Muscle mass determines whether or not a muscle can be safely used as an injection site. The gluteal muscle enlarges in response to use in walking. After the child has been walking for a year, it should be safe to use the gluteus maximus for injections.
