A postpartum woman has small vulvar hematomas. What nursing action should be taken to reduce swelling?

Applying an ice pack to the area is the appropriate nursing action to reduce swelling in the case of small vulvar hematomas. Ice application promotes vasoconstriction, which helps minimize blood flow to the area, thereby reducing swelling and providing pain relief. The cold temperature can also numb the area, offering additional comfort to the postpartum woman.

Although heat can be beneficial for muscle relaxation and improving circulation in some conditions, it is not suitable in the acute phase of swelling, as it may exacerbate the problem. Encouraging leg exercises is valuable for promoting circulation and preventing complications such as thrombosis, but it does not directly address the swelling of the hematomas. Administering prescribed pain medication can help manage discomfort but does not have an immediate effect on swelling.
