The injection should be given at a 45-degree angle.
The injection should be given at a 90-degree angle.
A bleb should form on the skin’s surface following injection.
Number 3 is correct.
IM injections are given at a 90-degree angle. A 25-gauge 1-inch needle is suitable for IM injections in children. A 45-degree angle is used to administer subcutaneous injections. A bleb should form only when giving intradermal injections.
