In order for my fellow nurses not to crucify me for spoonfeeding you w/ the answer, let me guide you how it's done instead.
First, identify the symptoms of the disease.
After you enumerate each one of them, identify which symptom requires the immediate attention.
Now correlate this symptom with an applicable Nursing Diagnoses.
Nsg. Dx: Activity Intolerance, Self-Care Deficit
Problem#1: Activity Intolerance (or Self-Care Deficit) related To Fatigue
Goal/s: The patient will... (you know this part already)
1. Anticipate the patient's need and provide the necessary assistance to perform an ADL (washing, grooming, etc.)
2. And so on and so forth....
Go ahead... you can do it!
