This paper describes the case of a patient with worsening renal function accompanied by electrolyte disturbance who required long-term hemodialysis after assessment by a medical team. The patient felt helpless due to restrictions in daily life and changes in their family role. The care period was from January 16 to February 2, 2020. In this period, observations, direct care, physical evaluation, medical record inspection, active concern, and open interviews were used for collecting information. Major health problems found included the following: 1. shortness of breath; 2. poor execution of dialysis diet; and 3. a sense of powerlessness. During the care period, picture teach the case to measure edema, and let the case study dietary water control skills through the use of water bottles and scales, nutrition-related information websites and several types of reminder mechanisms were employed, such as using cell phone charms or mobile alarms, to help the patient understand correct information on various dietary components and accept their current family role. This was done to make living with the disease easier for the patient. We recommend the inclusion of family participation for future studies on care of patients with similar conditions. Also, we should think of devising ways for increasing medical staff’s willingness to proactively take psychological counseling courses so that they can respond better to such cases in the future.
