Step-by-step explanation:
The most appropriate intervention for a patient admitted with epididymitis is warm packs to the scrotum. Epididymitis is inflammation of the epididymis, which is one of the paired organs within the scrotum where sperms mature and are stored. Applying warm packs to the scrotum helps to relieve swelling and pain by increasing blood flow to the area and promoting healing.
