The best method to verify "the right patient" in an unconscious client is to:

Choice A reason: An ID number alone lacks context; without name confirmation, it risks mismatching if wristbands are swapped, missing a critical identity check. Choice B reason: Name alone may coincide with common names; without a unique identifier like a hospital number, this method risks errors in a busy unit. Choice C reason: Name and hospital number provide dual identifiers; this matches the MAR precisely, ensuring accuracy for an unconscious patient per safety standards. Choice D reason: Calling an unconscious patient is futile; they can’t respond, making this impractical and unreliable compared to objective wristband verification.
