What is the maximum volume for a subcutaneous injection?

The correct answer indicates that the maximum volume for a subcutaneous injection typically ranges from 0.5 to 1.5 mL, which aligns with standard practices in administering medications through this route. Subcutaneous injections are utilized for medications that need to be absorbed slowly, and the body's subcutaneous tissue can generally accommodate volumes within this range efficiently.

Injecting volumes larger than this can lead to complications such as tissue distension, poor absorption, and increased risk of localized irritation or necrosis. The high end of the range, 1.5 mL, is considered the upper limit for a subcutaneous injection due to these factors.

The other choices do not reflect the accepted clinical guidelines. For instance, 1 mL represents a commonly used volume but does not cover the entire range in practice. Meanwhile, 2 mL exceeds the maximum recommended volume, leading to potential complications and is therefore not advisable. Understanding these guidelines is crucial for safe and effective medication administration.
