You would proceed with the physical assessment of an adult geriatric patient no differently than you would with the physical assessment of any other adult patient. So, any physical assessment sheet you might have would work.
I have been working on a review of systems/physical assessment sheet for students to use in their clinicals that you can download and copy, but it may not be what you are looking for. You can circle items in the Review of Systems area and write in your physical findings in the physical assessment area. It has two typos on it at the moment that I have not corrected.
There are some special assessments that can be specifically done with geriatric patients that pertain to their risk for falls, confusion, incontinence and other common areas of concern. You can see a listing of them here and link into and download the assessment tools that are used as well. Some of them are used by evaluators in nursing homes. However, they are NOT part of what you would call a routine head to toe physical assessment.
