Final answer:
To distinguish between a hernia and a hydrocele, a physical examination is necessary. A hernia is identified by a bulge in the inguinal region, while a hydrocele can be distinguished by transillumination. Jeff should seek medical evaluation for an accurate diagnosis.
Step-by-step explanation:
A scrotal mass can be challenging to assess if the scrotum is edematous. To determine if it is a hernia or a hydrocele, a physical examination is necessary. A hernia is a protrusion of tissue through a weakened area in the abdominal wall. It can be identified by a bulge in the inguinal region that may be reducible or non-reducible. On the other hand, a hydrocele is a collection of fluid in the scrotum due to the accumulation of fluid around the testicles. It can be distinguished from a hernia by transillumination, where a light shone through the scrotum will cause the hydrocele to glow. Ultimately, a healthcare professional should evaluate Jeff's scrotal mass to determine the precise diagnosis and appropriate management.
