Am angry with sister-am I right?

[tingly]

My 84 year old mother recently had a small fall and is suffering from bruised ribs and a broken toe.
She did this last wednesday morning by stumbling in her bedroom.
I am my mums main carer ( I live 5 miles away) and stayed the night with her the first night it happened as she was shook up, and i visit everyday anyway, but have been at her house all day every day the last week to take care of her- doctors, washing , ironing, shopping, gardening, bathing etc.
I needed today 'off' as it were, as I had to catch up with a number of things . My sister said she would visit for an hour or so- and she took her husband.She knows my mum is on strong painkillers, but took a bottle of champagne with her and all 3 sat in the garden and drank this-unbeknown to me.
I rang my mum to check on her at about 3 oclock today, and it was clear something was wrong as she sounded funny.. I rang my sister to ask if she had seen my mum take too many tablets/have a drink and she said 'no'
My mum then rang me at 6 to tell me my sister had bought the champagne in question

I am really angry- a. because my sister lied to me. b. because i do all the mundane jobs, pay for my mums house and all her bills, take her to hospital when necessary ( my sister doesnt 'do' hospitals she says)-- and then my sister gives my mum drink after she has had a fall.

I could honestly cry--i try and get my mum better then she gives her drink. My mum of course loved it-but then she would cos she's on tablets and is now out of it.

am i being uneccessarily harsh. I'm really fed up.
