High Blood Urea and Creatinine.

My Grandmother is 94yrs old and was very stable and active. She fell down at bathroom 3days ago and slightly injured herself. From the 3rd day she wasn't able to speak properly and went in a state of confusion. Was experiencing pain in the lower back area probably from the fall. After taking to hospital, CT scan was ok but KFT report was not good and showed Blood Urea of 153.4mg% and Serum Creatinine of 5.63mg/dl, Uric acid 8.40 mg/dl, Sodium 133.10mEq/L, Potassium 5.81mEq/L, Calcium 8.20mg/dl. Her CBC also shows platelet count is also very low 0.58 Lacs/ul. The doctor at hospital gave following medication: Panterp DSR, NephroSave Forte, Dytor 5mg, Ultramol, Citilek P, Meganeuron OD, Syrup Marirgyl She was discharged the same day as doctor said nothing much can be done. Please suggest if there is any course of treatment to keep her stable and back to normal so that she can speak normally..which she was just two days ago and now she almost is in a state of confusion.
