There is a lot to learn on the fly
Walking into clinicals without any hospital experience reminds me a bit of walking into a gym for the first time.
There are so many pieces of equipment with specific ways to use them... free weights, weight machines, treadmills, TRX bands, kettle bells, ellipticals, spin bikes... the list goes on and on.
Not only do you have to know how to use the equipment (and plethora of options) but you also have to know how to plan your workout to fit your needs, interests, and capabilities.
It's a major learning curve for a gym newbie!
It reminds me of the first time I walked onto a nursing unit, and people were talking about telemetry, Kerlix, secondary tubing, code browns, and somehow I felt like I just walked into a different world.
I remember being told to go do a total bed change on a patient and just standing there looking like Kevin McCallister being asked to pack his suitcase on his own.
