Which of the following charges could be filed by a patient if a provider performs an invasive exam without obtaining informed consent prior to the procedure

Assault refers to the act of creating a reasonable apprehension of imminent harmful or offensive contact. While the patient may feel apprehensive about the procedure, the actual performance of the exam without consent constitutes battery rather than assault. Therefore, assault is not the correct charge for the physical act that took place.

Negligence involves a failure to provide the standard of care resulting in harm to a patient. While a lack of informed consent may indicate negligence on the provider's part, the specific act of performing an invasive exam without consent is classified as battery due to the direct physical contact, hence negligence does not apply here.

Libel entails making false written statements that harm an individual's reputation. This charge is unrelated to the context of unauthorized medical procedures and does not pertain to physical contact or informed consent, making it an incorrect choice in this scenario.
