Final answer:
Patient height and weight are not required on an informed consent form, which must include the procedure name, risks and benefits, and possible alternatives.
Step-by-step explanation:
The correct answer to the question of which information is not required on an informed consent is C. patient height and weight. An informed consent form is a crucial document in research and medical procedures to ensure that participants are fully aware of what the study or procedure involves. It must include the name of the procedure, the risks and benefits of the procedure, and any possible alternative procedures. However, the patient's height and weight are not standard requirements for informed consent documents and do not directly contribute to the understanding or voluntary participation in the procedure or study.
