These mental status challenges are not necessarily designed for the patient to determine if the patient can get the correct answer. The intents for some of them are to observe the patient's ability to persevere, to stay focused on the challenge, to observe the patient's frustration and ability to self-correct and how the patient attacks particular mental tasks.

People are sometimes not as forthcoming in the clinical setting as they are sitting in their underwear in the computer trying to determine if that last shot of vodka or those extra cannolis are making their side ache.
