What is the difference between express consent and implied consent, and in what situations is implied consent commonly assumed?

• A. Express consent is explicit (written or oral); implied consent is inferred from actions or circumstances (e.g., during urgent care when patient is unable to respond).
• B. Express consent is inferred; implied consent is explicit.
• C. Express consent is not allowed in medicine.
• D. Implied consent requires always written documentation.

Answer: (A)

Express consent is explicit and communicates agreement directly, either in writing or spoken aloud after the patient is informed about the procedure, its risks, benefits, and alternatives. Implied consent is not stated outright but is inferred from the patient’s actions or the clinical context, especially when the patient cannot respond or when the situation requires timely treatment to prevent harm. A common scenario is urgent care or emergencies where the patient is unconscious or otherwise incapable of giving consent, and the clinician reasonably assumes the patient would consent to treating necessary conditions. That makes the best answer: express consent is explicit (written or oral); implied consent is inferred from actions or circumstances (such as during urgent care when the patient cannot respond). The other statements blur the definitions or assert things that aren’t accurate: consent can be express in medicine, and not all implied consent requires written documentation—implied consent is often inferred without any written record.
