Which of the following is true about IM injections?

Explanation:
IM injections must reach the muscle tissue, not just the subcutaneous fat. For most adults, a needle about 1.5 inches long is sufficient to penetrate the muscle in common sites like the deltoid or gluteal region, ensuring the medicine goes into muscle tissue. A shorter needle (around 1 inch) may not reach muscle in individuals with more body fat, while a longer needle (about 2 inches) is needed for some very lean or very obese patients depending on the site. A 3/8 inch needle is generally used for subcutaneous injections, not IM. So using a length of about 1.5 inches aligns with typical practice for IM injections, with adjustments made for patient body size.
