You are forgetting Richard Armitage in The Vicar of Dibley.
Having spent years in cath labs and operating theatres - there is blood, the blood gets wiped on the Dr's gown s/he needs to not have hugely wet hands so they wipe them on something sterile, usually their gown.
Also the Dr is not on their own (in a cath lab) you will have at a minimum a scrub nurse, usually there is a scrub nurse, a radiographer, circulating nurse, tech and may a couple of other trainees.
No one ever flatlines, what you see on film / TV is electrodes not attached. What we call a flatline looks more like a badly hand drawn line.
One thing that DOES happen IRL is junior Drs phoning for the results of a 24 hour tape when the patient is still wearing the tape. The clue is in the name, it records for 24 hours, we can't analyze it until then.
Teaching - I think has mostly been covered but as a supply teacher I'm lucky if I can teach one of the subjects I have either trained to teach or have an interest in. but I might be covering Spanish or Music or resistant materials.
Sorry to anyone on here whose children have had a supply teacher I can't let you use the machinery, I don't know how to use it safely so I can't let you. Sorry you can't play the musical instruments, I've been given work and that is to design a poster.
I know it's crap, I know you deserve someone who can teach you to use the equipment, but I'm onsite and the school needs to get their money's worth.
