Consent is informed.
Withholding the fact that a person has been raped is exactly the same as a doctor withholding a cancer diagnosis. They do not have that option and cannot have that option. The patient must have the relevant information to be capable of managing their treatment.
No, it is not. That is not informed.
Information being shared with the patient is not something that takes their consent. It is the baseline bare minimum obligation of every provider in every circumstance.
A lawyer can’t allow a client to decline to hear a plea offer. A doctor can’t choose to allow a patient to make any decision without being fully informed of everything the doctor knows relevant to their case. The information is always mandatory, and it’s always malpractice not to provide it.
