What should be done before administering medications through a PICC line?

Before administering medications through a PICC line, cleansing the port with alcohol pads is essential to reduce the risk of infection and maintain sterility. Given that intravenous access can introduce pathogens directly into the bloodstream, ensuring that the port is disinfected is a crucial step in safe medication administration.

While checking the patient's blood pressure, reviewing the medication order, and confirming the patient’s identity are important protocols in overall patient care, they do not specifically address the immediate step of preparing the PICC line for medication delivery. Cleansing the port directly addresses aseptic technique, which is vital in preventing complications such as bloodstream infections during the medication administration process.
