True story from another site.
****************************

But the funny part is it's true!
I was working at a large general hospital that shall remain nameless (to protect me!). The Registrar (the senior doctor, teaching the student doctors) was conducting his rounds, in the medical ward. One patient, an 83 year old gent, had become incontinent of urine (wetting his bed). One Female student says "catheterise him!". The Registrar suggests perhaps a uridome (imagine a heavy duty condom with a tube running out the end) would serve as well, with less risk of infection? "Oh yes!" cry the students. "Well, put on on him" says the Registrar.
Female (blonde) Student: 'how does it go on?"
Registrar: 'The same as you would put a condom on a male!"
Student: (blushing) 'Oh!'
Registrar: 'Get on with it, after we finish rounds'

Rounds finished female student comes back to ward to carry out assignment. Now instead of just getting one of the nurses to do it, she insists on doing it herself. Grabs all the kit, pulls the drapes around the bed, and gets to work.

About 20 minutes later the Clinical Nurse says "what the %$#@ is going on in there?" Grunting, groaning, moaning etc. Doc, you had better take a look.

I quitely announce myself at the drawn drapes, and ask if everything is OK?

She bids me enter, she is having trouble.

I pull back the drapes to reveal a certain female (very blonde) medical student jacking off the old guy, who had the biggest grin!

WTF do you think you are doing! "But the registrar said to put it on like a condom! And I can't get him to go hard!"

There truly are times when words fail me, I simply walked away and sent the nurse in, went out , sat on the steps and laughed my arse off!
About 30 seconds later the nurse joined me on the steps, laughing so hard she cried!

And who says the Public Health system is flawed?

BTW, she passed, and is now out there, somewhere, practicing as a urologist!

Cheers, Dave.
