You did good. Mom's side of the family tend to go into nursing/medical - so have several cousins who are in that field. They are hugely overworked. But one thing any good nurse in a well run hospital will encourage is for family members to assist whenever possible. It keeps the patient calm, having someone familiar to help them, even in unfamiliar surroundings.
My cousin Trudy (midwife now, but was a RN for years) says "Calm is good. They are more likely to heal, with fewer complications." - just happened to be on the phone to her when I read your reply, so I asked her.
Thanks! Around 10 or so years ago, I got a degree in Human Services, along with getting certificates as an NA and Activity Director. I worked in the fields for a time, but my husband had Alzheimer's, so that stopped my college career and working. However, I was VERY lucky to have the skills needed to help him. Everyone should take NA courses. They are cheap, and don't take long to learn the skills. Many can earn a few bucks doing home nursing. Since I'm an old fart, I help friends and relatives who need home care, without charge. It's my way of paying back their friendships over the years. Besides, most of the skills taught, we already know through life experiences.
