87yrs Grandmother having frequent fever.

My Grandmother is 87 yrs old and is paralytic having diabetes and hypertension. She is having regular fever since last 10-12 days and it subsides after giving Dolo 650.  Her Malaria and Typhoid tests were negative. Liver Function Test was also ok. She was given Augmentin and Uribid (contains Nitrofurantoin) for 3-4 days till the Urine Culture report came on 27/04/20 which is attached. After the culture report Augmentin was stopped and Farobact 200 (contains Faropenem) and Uribid were given. She was not getting comfortable so CBP was done on 01/05/20 report is attached. After the report Zocef CV 500 (Contains Cefuroxime 500+ Clavulanic Acid 125) was given instead of Farobact 200 which was given 8 tablets to her so far. Uribid was continued. She is taking this since last 3 days. In this lockdown phase and looking at her age and other conditions, it's impossible to take her to any hospital or doctor. Please suggest a suitable remedy for her existing condition
