A patient with obsessive-compulsive disorder (OCD) is most likely to exhibit which of the following physical findings?

In individuals with obsessive-compulsive disorder (OCD), one common behavior that may lead to notable physical findings is excessive hand washing or cleaning compulsions. This can result in raw, red hands due to the frequent use of soap, water, and sometimes harsh antiseptics. The action of compulsively sanitizing hands can create physical stress, leading to irritation and damage to the skin, making option A the most likely physical finding in this context.

Other options, while they may present in various conditions or situations, are not characteristic indicators often associated with OCD. Memory impairment is not directly linked to OCD in the same way as excessive hand washing is. Abdominal pain is not related to obsessive-compulsive behaviors, and priapism, which is a prolonged and painful erection, does not correlate with OCD symptoms. This makes raw, red hands the most appropriate choice given the specific behaviors often exhibited by patients with OCD.
