Look at the ones in the book, then personalize it to the patient. Simple and easy to do....in theory, a little more difficult in practice.
Here are some hints--look at the patient's history, and the physician's orders.
Personalizing a care plan to the patient can be as easy as stating something like "titrating o2 to keep SpO2 >90%, as per physician order" or "Aerosolized albuterol treatments q4h and prn wheezing, dyspnea (as per physician order)" PT/OT orders, diet orders, activity orders, med orders, all these things can be used to personalize care plans
If the standardized care plan mentions ambulating in halls TID but the patient isn't ambulatory, then you personalize it to that patient. Something like institute passive ROM TID to maintain strength et promote circulation. If a patient comes in and cannot adequatey reposition herself, personalizing the care plan would be to institute a nursing action of turning the patient q2h et prn to maintain skin integrety r/t pt's weakness, lack of activity.
Another personalization would be a patient with a history of CHF. Even if the doc didn't order strict I/O or daily wieghts, you would implement these based on the pt's history--again, another means of personalizing the care plan.
Does that help at all? Or were you already doing these things, and the instructor wants even more?
