Final answer:
The optimal nursing intervention to minimize perineal edema after an episiotomy is application of cold packs.
Step-by-step explanation:
The optimal nursing intervention to minimize perineal edema after an episiotomy is application of cold packs.
Cold packs help to constrict blood vessels, reduce inflammation, and alleviate swelling in the perineal area. This intervention is safe and effective in promoting healing and relieving discomfort.
Other interventions such as administration of diuretics, encouraging prolonged sitting, and avoiding fluid intake do not directly address perineal edema and may not provide the same level of relief.
