In what circumstances should skin be cleansed before giving an I'M injection?

Skin should be cleansed before giving an intramuscular (IM) injection to reduce the risk of infection. This is especially important when the injection site is visibly dirty or if the patient has compromised skin integrity. Alcohol swabs or antiseptic solutions are typically used to disinfect the area, ensuring a sterile environment for the injection. Additionally, cleansing is recommended for all patients as a standard practice to maintain hygiene and safety.
