Final answer:
To protect the patient and the intravenous (IV) insertion site from injury due to the patient's erratic movements, the nurse can apply an IV site-protection device over the site.
Step-by-step explanation:
To protect the patient and the intravenous (IV) insertion site from injury due to the confused patient's erratic movements, the nurse can take the following action:
A. Apply an IV site-protection device over the site, such as House UltraDressing.
This will provide a barrier between the patient's movements and the IV insertion site, preventing accidental dislodgement or injury. It is important for the nurse to assess the patient frequently to ensure the IV site remains intact and the patient is safe. Instructing the patient to avoid dislodging the IV catheter is also important, but it may not be effective if the patient is confused and may not be able to follow instructions.
