Practicum/Capstone Clinical Question

I was just curious if other students had been told their hospital facilities do not allow them to do any IV pushes, lab draws from central lines or any access to central lines, opioids, sedatives, warfarin/heparin, hypertonic solution, KCL or neuro blocks even with a preceptor present guiding them on their final clinical. It's a hospital wide policy for all nursing students. I understand why some of those drugs aren't given but Im not sure when I'm supposed to learn some of this stuff. Some floors might not be affected by this but I am going to be on an ICU unit and I'm concerned I will not possess the basic skills to work on this unit when I am done if I'm not allowed to do these things when I imagine it's quite common for ICU patients to be on these drugs or have central lines.

is this a normal thing?

Full disclosure: this practicum I have been selected for is a transition role where they offer you a job at the end and it's designed that you stay/sign a contract to work in that unit which is why I'm ultra confused at why they wouldn't want to train me if I'm staying on after
