General, it is the responsibility of a doctor to ensure that they provide medical treatment which is equal or better than what would be expected in their field. They must treat and diagnose their patients in a competent manner and according to accepted medical standards. Medical malpractice may result if a doctor breaches this standard and injures a patient.
A physician can be held responsible for his or her own actions as well as those of the staff that they supervise. This includes nurse practitioners and physician assistants if the latter were working within their scope of employment.
Maggie’s and your own liability depends on the circumstances and roles of each party. You may also be held accountable for harm done to patients if, as a nursing professional, you have been found negligent.
You should consult an attorney if you’re concerned about legal implications.
It is always best to follow professional standards when providing medical treatment and document all actions taken or any decisions made. Documentation can provide evidence in the event that a dispute arises. You may also want to contact the regulatory or oversight agency if there are any concerns you have about the doctor’s actions or those of other healthcare professionals.
