Final answer:
The nurse should apply a transparent film dressing over the patient's venous access site to monitor for infection and provide a barrier against contaminants.
Step-by-step explanation:
The nurse should apply a transparent film dressing over the patient's venous access site.
This type of dressing allows the nurse to monitor the site for signs of infection, such as redness or swelling. It also provides a barrier against bacteria and other contaminants, helping to prevent infection.
In addition, a transparent film dressing allows for easy visualization of the site, allowing the nurse to assess the condition of the vein and the surrounding skin.
