You are working in a nursing home as a formal caregiver. The client you are assigned to is William Kerr, who has hearing loss, reduced level of attention and repeated reports of falls. One of the prescriptions of Dr Stewart who is a neurologist in the nursing home is Falls Prevention Program. You were asked to inform Henry that he needs to attend the physiotherapy ward three days per week to participate in their Falls Prevention Program. You go to Henry's room and explain that he needs to participate in the program due to the falls incidents that he experienced recently. Henry nods his head confirming that he understood what you meant. However, you know that Henry has hearing loss and reduced level of attention. Therefore, you need to use other strategies to ensure Henry has completely understood you. How can you confirm a person has understood you?.
