My wife went to hospital last sunday,trauma and her exrays showed she had a lung infection. she has tested negative for covid. she has been taking the prednisone and vitamins however she is getting a cough early hours of the morning and this is givin?

Perspective: Likely, she had a "rapid" test, but these maybe false negative in ~40% of cases. Best to repeat, but get COVID-19 PCR testing. For time being, stay quarantined. You do not mention antibiotics, but these may be needed if bacterial infection is present (which could be a superimposed co-morbidity). See your doctor in followup

How can we help?: Pneumonia or other lung infections could be related to COVID 19, other viruses or bacterial infections. I don't see a question here. Did you have a particular question about her care or her condition?????
