To assess a client’s ability to concentrate, the nurse would instruct the client to do which of the following?

Choice A reason: Repeating the days of the week backward requires sustained attention, working memory, and mental sequencing. It is a direct and effective method for assessing concentration. Choice B reason: Describing a typical day assesses memory and insight but does not challenge the client’s ability to focus or maintain attention on a cognitive task. Choice C reason: Explaining a proverb assesses abstract thinking, not concentration. It evaluates cognitive complexity and interpretation skills. Choice D reason: Naming past presidents tests long-term memory recall, not concentration. It does not require sustained mental effort or attention.
