My sister has the medical POA. Over the past couple months she has made some questionable decisions with my moms medical care. She cancelled my moms cardiology appointment. My mom has heart failure and the cardiologist was working on having her edema reduced. My sister lied and told them when she cancelled the appointment that mom was doing better. Her feet were grossly swollen-enough to have to buy new bigger shoes. Moms PA put her on amlodipine 10mg which I found out for an elderly person they should only be on 2.5 mg. Side affects include swelling, fatigue, dizziness and a host of other side affects. If you read an earlier concern I had about the PA scope of practice, this is the same PA. Lately I noticed in moms records that when mom was put on amlodipine moms blood pressure spiked to 200/100. This is when I saw that my sister had her off her B/P medication for almost 6 weeks. I am still waiting to hear back from her why she was off of her meds in the first place. Then the other day she had an appointment. I went to pick mom up when she suddenly was in extreme pain in her neck which dissipated then intensified. The nurse and I decided to call the ambulance not knowing what was going on. When I called my sister her words were, "was it necessary to call the ambulance". I am second in line for the medical POA but feel I need to keep an eye on the medical because of these recent actions. Any thoughts on how I can confront my sister to allow me to take her medical. My sister has the financial POA too which she does an excellent job at.
