If you're planning to file a medical malpractice lawsuit or simply want to know more about what it is so you can make a better judgment about whether or not you have a case, you need to understand that not all injuries suffered in a hospital or due to a medication are caused by malpractice. Some things, like allergic reactions patients didn't know about or injuries that were a potential result of treatment are within the scope of your care. However, if you were to tell a doctor you had an allergy to ibuprofen and then were given that drug by the same doctor, that could be construed as negligence.
Medical malpractice laws are in place to help you get compensation after you suffer harm from a substandard medical treatment. So, if you are injured during surgery because it was performed on the wrong site, you could choose to seek compensation for those injuries, your medical bills, and your pain and suffering. Doctors, nurses, and the hospital itself are all responsible for your injuries if they resulted from a deviation from the quality of care that is expected.
