Final answer:
The nurse should assess the wound and the drainage, and change the dressing more frequently if the drainage is excessive. It is important to monitor for signs of infection.
Step-by-step explanation:
When a client has a transparent film dressing over a wound that is showing a large amount of drainage, the nurse should proceed by assessing the wound and the drainage. If the drainage is excessive and soaked through the dressing, it may be necessary to change the dressing more frequently to maintain a clean and moist environment for wound healing. The nurse should also monitor for signs of infection, such as increased redness, swelling, warmth, and pain, as well as fever and changes in the character of the drainage.
