There's negligence, and then there's gross negligence. For example, someone can have a bad reaction to a medication that was reasonable prescribed, but the patient can still sue, because "Murrica." Or, a medication can be prescribed unreasonably, say, prescribing Xanax for anxiety and Benadryl and ambien for sleep in an 80 year old with cognitive difficulties and fall risk factors. When that person inevitably falls, or lights the house on fire due to a confusional episode, that family can also sue. In one of those cases, your legal representation has a very good argument that you are practicing outside of reasonable bounds and can conceivably try to justifiably throw you under the bus to limit their liability.
