Final answer:
To ensure adequate filling of the drip chamber when changing a client's IV tubing and closing the roller clamp, the nurse should hold the IV bag higher than the entry point, create sufficient pressure, and position the IV bag correctly.
Step-by-step explanation:
When changing a client's IV tubing and closing the roller clamp on the new tubing setup, the nurse should take the following action to ensure adequate filling of the drip chamber:
- Hold the IV bag higher than the entry point into the arm, at a height of about 0.24 m.
- Make sure the IV bag is at a sufficient height to create pressure that pushes the solution into the arm.
- Position the IV bag correctly, with the saline solution surface about 1.61 m above the needle entrance.
By following these steps, the nurse can ensure that the drip chamber fills adequately and the solution flows properly into the client's arm.
