The first time I ever had a pre-employment physical I was about 17. I had gotten a job in the dietary department in a hospital kitchen. Before I could start, I had to go to the Employee Health office for an exam. (This was the late 70's) They gave me a form and an appointment.
I came in for my appointment and gave the NP the form. She asked all the usual questions, had some basic labs drawn and had me get a urine sample, then had me undress to my underwear. She started with height and weight, then temp (oral), pulse, BP and respirations. Then there was the standard, HEENT, heart, lungs, and abdominal. Then she had me sit up and checked my reflexes and strength. She then had me stand and observed my gait and checked my spine. She then informed me that since this job required a good deal of heavy lifting, she needed to check me for a hernia and told me to drop my underwear and stand with my feet apart. She checked my testicles and did a hernia check, then had me turn around to do a visual of my rectum for possible hemorrhoids. (She did not do an internal exam) Then she had me dress. Next, she gave me a TB test and told me I would have to come back in 2 days to have it read. Just before I left, she handed me a specimen cup in a paper bag. I had to collect a stool sample and bring it back to test for parasites, etc. (Pretty standard for food service)
It was, to that date, perhaps the most complete physical I had ever had. The next one I would have was my induction physical, which I have described elsewhere. After leaving the Navy a decade later, I again went to work in a hospital, this time as an OR orderly. It was similar but was more detailed. I can tell you about it if you want.
