Question

For a intramuscular injection, at what angle to skin should the needle be inserted?

a) 45°
b) 90°
c) 35°

Answer 1

The correct angle for an intramuscular injection is 90°, as it allows the needle to reach deep into the muscle tissue for proper medication administration.

Step-by-step explanation:

For an intramuscular injection, the correct angle to insert the needle into the skin is 90°. This means that the needle should be inserted perpendicular to the skin's surface. This angle ensures that the needle reaches deep into the muscle tissue, which is necessary for the proper administration of the medication. Inserting the needle at a 45° angle is more common for subcutaneous injections, where the medication is administered into the fat layer beneath the skin. The angle of 35° is not typically used for standard injection techniques.
