Final answer:
The nurse should include changing the perineal pad and reporting the drainage in the plan of care for a postpartum client after a vaginal delivery.
Step-by-step explanation:
The nurse should include changing the perineal pad and reporting the drainage in the plan of care for the client. After a vaginal delivery, the perineum can be swollen and tender, and it is important to keep the area clean to prevent infection. Changing the perineal pad regularly helps maintain cleanliness and allows the nurse to assess the color, amount, and odor of the drainage, which can indicate complications such as infection or hemorrhage.
