The hotel idea is a good one--several students did that when the hospital was far from their homes, esp. in the winter. Plus, no early morning storm surprises.
Are the other students having difficulty? Have you talked to your instructor--not to complain, but to see if she has any suggestions. One of our clinical instructors overheard us talking the first morning of that particular rotation about how little sleep we'd gotten the night before r/t working on care plans
. She told us to start with the medication part of the care plan and then get as much done as we could, but she didn't want us working after midnight at the latest. Another instructor had us turn in the meds portion first thing, and then we could work on our care plans (labs, etc.) during the day if we had any spare moments, and not turn it in until the following week.
I also made my own template (with the instructor's permission) that was easier to fill in (and correct) than the "official" one and the other students ended up using that for their careplans, too.
If nothing else, just know it does get easier. You'll get to the point you can knock out care plans without a second's thought.
