The insertion of a peripheral IV line involves the following steps: 1. Preparation: The child’s skin is cleaned with an antiseptic solution to reduce the risk of infection. 2. Insertion: A needle is used to insert the catheter into the vein. Once the catheter is in place, the needle is removed. 3. Securing: The catheter is secured with adhesive tape or a dressing to prevent dislodgement. 4. Flushing: The IV line is flushed with saline to ensure it is functioning correctly.
