failure. Aim: - determine the effectiveness of a designed nursing teach back strategy and 
patient's self-care nutrition on daily livings activity of heart failure patients. Subject and 
methods: -   Randomized controlled trial design was utilized. A simple random sample of 
sixty adult Patients with heart failure seeking treatment at cardiology department at Tanta 
University were chosen, allocated, and split into two equal groups randomly. Group I: 
control group were given regular nursing care by hospital nurses and under prescribed 
treatment by physician. Whereas a designed nursing teach back strategy and individualized 
patient's self-care nutrition as calculated and implemented by researcher and under prescribed 
nutrition by physician was provided to group II (study group). Tools: Three tools were used 
to gather relevant data for the investigation, Tool (I) included Assessment questionnaire, Tool 
(II) included Nutritional assessment sheet and Tool (III) was clinical outcomes assessment 
sheet. Result: The main result revealed that slightly more than half of the control group I and 
the minority of the study group II still had moderate functional impairment two one month 
after implementing individualized teaching nursing strategy about nutrition. Conclusion: 
Individualized patient's self-care nutrition to maintain healthy and safe food intake based on 
patients' needs had positive effect on improvement of activity of daily livings of study group 
II.

patient's self-care nutrition should be given to patients upon admission and followed after 
patient discharge by cardiology nurse.
