Which of the following is NOT required information for informed consent?

Informed consent is a critical process in ensuring that patients are fully aware of and agree to the medical procedures they will undergo. The key elements of informed consent typically include explanations about the procedure itself, expected outcomes, potential risks, and any pertinent patient history that could impact the procedure or outcomes.

The correct answer highlights that patient height and weight are not essential components for obtaining informed consent. While these metrics may be relevant for certain medical assessments or procedures, they do not directly contribute to a patient's understanding of the specific procedure at hand or the associated risks and benefits. In contrast, patient history and allergies are crucial for tailoring the procedure to the individual and for ensuring their safety, while expected outcomes and risks allow patients to make an informed choice regarding their healthcare.

In summary, while height and weight can be used for treatment decisions in some contexts, they are not fundamental for informed consent related to a specific medical procedure.
