What is an essential step after administering an IV medication?

Flushing the line with saline is an essential step after administering an IV medication because it ensures that the medication is fully delivered into the circulatory system and helps maintain patency of the intravenous line. This action allows you to clear the line of any residual medication, ensuring that the full dose has been received by the patient and reducing the risk of complications such as phlebitis or blockage of the IV catheter.

It is also important for verifying that the IV line remains open for any subsequent medications or fluids that may be administered later. This practice supports both medication efficacy and patient safety.
