Hi! First off, I think it is important for you to know the difference between a nurse and a caregiver so as to understand which one suits your (and your grandma) needs best. Nurses themselves have different categorization. The most common categorization is Enrolled Nurse (EN)/Registered Nurse (RN). EN assist RN to provide holistic nursing care for patients and usually possess the Higher Nitec Certificate from ITE. To be a RN, you have to obtain a nursing diploma/degree. RN usually develop their nursing skills in specific specialties. Of course because of this, RN are more expensive than EN. Nurses in general, perform more skills specific tasks like wound care, dressing changes, IV and infusion therapy, medication administration, injections, and tube feedings. Basically the more technical stuff.

Caregivers on the other hand usually do not possess any nursing certification. They usually provide hands-on assistance with respect to the client's daily life. Some of the tasks they handle include bathing, dressing and grooming, medication reminders, light housekeeping and laundry, transportation services, meal prep, assistance with toileting, companionship, etc. The list is non-exhaustive.

So now, that we understand the difference between nurses and caregivers, to answer your question, I think your grandma might only need a caregiver and not a nurse because you did not mention anything very technical tasks like changing of dressings or infusion therapy. But of course, I am not very sure of the specific requirements you might have so i think is best if you can approach people who offer such services to find out more. Hope this helps :)
