malpractice insurance for nurses

Doctor perscribed antibiotics feels are not necessary before seeing the patient. Is this malpractice?
My dad is in a center rehabilitation after stroke. He had a trach put in, and, recently, we (the family) began to notice a bad smell when you cough, accompanied by blood in their sputum. After noting that a nurse, a test was done in his sputum and found two bacteria. My father is put on antibiotics. Two days later, his doctor (who has seen it all twice in the last three months) comes and tells us that according to his professional opinion, the father does NOT have an infection, and no reason for him to be on antibiotics perscribed Hon. Also I will report that it's really dangerous to the dad that treatment with antibiotics, but that put him there, because it was the wish of the family. Never was – just wanted to know if there was an infection. Today we learned that is charging more than $ 1500 for drugs that have asked (never did). The insurance does not cover this. Is this legal? What can we do? Certainly, We can not afford.
First of all, you have to get another doctor to see her father. This doctor is dangerous for your health! A person in a tracheotomy should be assessed more frequently than twice in three months. You also need a second opinion. Request copies of all your medical records. (You can not deny this!) It is also necessary to obtain an itemized bill. If he is on Medicare or Medicaid, you need to contact them, sounds like you are committing fraud. Also need to consult with an attorney, most will tell you about an initial consultation at no cost. I also know of any antibiotic that costs a lot for a course two days! If your father is with fever and have a bacterial infection, antibiotics are needed.
