Here's the thing about nursing homes.... they are homes. The people there are residents, not patients. They are receiving supervision with their activities of daily living (bathing, dressing, walking) and/or their instrumental activities of daily living (shopping, cooking, cleaning, etc) because they are disabled in some way (cognitively and/or physically). So, they aren't receiving clinical services on a daily basis in most cases (aside from being administered pills, and perhaps an insulin injection, by a nurse). So, how is this different than a person who is seeing a doctor and being questioned about symptoms, being ordered to undergo tests and being provided information about diagnosis and treatment.
Spending time with the disabled is good experience for a clinical role, as many of the people who physicians care for have disabilities, but being in a nursing home is, in my opinion, not being in a clinical setting unless you have a physical hands-on role as a patient care technician (in which case the word patient is in your title and that's a more "patient" oriented thing as is done in the hospital -- bathing the patient, safely getting them to and from the bathroom, etc).
