The only exam I remember being completely nude from the beginning, I was in a hospital...specifically, the locked ward.
It was at Camp LeJeune. Although I made no attempts, i was very depressed, and had major suicidal tendencies. I was admitted in the afternoon, and placed in a room that could be seen from the nurses station. (Suicide watch) I had to remove all my clothing. Neither the room or the bathroom had a door, and the mirror was metal. I don't remember if I had a blanket on my bunk or not, but I was naked that whole first night. (The way I was feeling, i really didn't care.)
The next morning, a nurse came in with breakfast (on paper plates with plastic utensils) She stayed with me while I ate, then took the tray and gave me a robe. A doctor came in right after that and walked with me down to an exam room. (Odd that they did the exam in private when I was fully exposed, at least to the staff, the whole previous night.) When we got to the exam room, the doctor had me remove my robe and did the most complete physical exam I ever had. He even checked my gait and spinal alignment. (He actually noticed that my pelvis was tilted, something most doctors missed.) For a psychiatrist, he really knew his physical medicine. There was absolutely NO PLACE he didn't examine. (Including under my foreskin and the DRE.) Once he finished, he had me put the robe back on, and we started talking about why I was really there. He determined that, although I needed to stay for medication and intensive inpatient psychotherapy, I was not, at that time, a danger to myself. I was removed from suicide watch and given back my uniform. (Since it was a military hospital, military discipline was observed. No pajamas during the day, PT (Consisting primarily of walking/running laps on the floor) in the morning. Reveille and Taps were observed. (Up before 6:00 AM, lights out at 10:00 PM) After a few days I was judged to be "safe" for outdoor exercise. (A fenced in area with a basketball hoop, and not much else,) and was given access to the "Slops chest." (A Navy term. It was a closet where previous patients had, either intentionally or accidentally left articles of civilian clothing behind) We could only wear civvies on these "outings."
After a careful review of my medical records, as well as what was said in both group and individual therapy, it was determined that I was no longer fit for military service, and that, indeed, even if these anxiety/depression/psychotic tendencies existed before hand, the military brought it out, and was therefore classified as a "Service connected' disability. (It was noted by this sharp eyed doc that I had had "adjustment difficulties" or "Stress management" issues at every duty station I was at from Boot Camp on. It only took them 10 years to put the pieces together.)
A medical board was convened, and I was placed on the "Temporary Disability Retirement List" I returned to civilian life a broken man. Two years later, the Navy permanently retired me and turned my care (and pension) over to the VA. That was 1991. By 1996, after several more such "vacations" and even a couple of courses of ECT, I was deemed , in VA speak "70% Disabled and 100% Unemployable." which, in non-government-eses means complete disability. (This...condition... could be directly linked to every job I had and left/lost from the time I left Active duty in 1989 until 1996.)
Official Diagnosis... Anxiety Disorder with depressive tendencies, psychotic episodes and PTSD. To this day, I still am on medication and see my VA shrink about once a month. (More frequently if needed. I also have her on speed dial and her e-mail) It took me a very long time to ease my guilt over this. i didn't feel I deserved the same compensation as people who had been wounded or maimed in the line of duty, but I was finally convinced by my doctor that there was no difference, except my wounds are not visible on the outside.
