A patient has been in the intensive care unit for 10 days. He has just been moved to the medical-surgical unit, and the admitting nurse is planning to perform a mental status examination. What should the nurse expect during this patient's tests of cognitive function?

A. May show evidence of some clouding of his level of consciousness: While patients who have been in intensive care for an extended period may experience some clouding of consciousness or altered mental status, it is not a universal finding. This option implies a more significant alteration in consciousness than typically expected in a patient transitioning to a medical-surgical unit. B. Will be oriented to place and person, but the patient may not be certain of the date: This is a common expectation for patients who have been in an intensive care setting for a prolonged period. They may maintain orientation to person and place due to their familiarity with the environment and staff, but they might have difficulty recalling the date due to the stress of hospitalization and changes in routine. C. Disruptive behavior: While some patients may exhibit changes in behavior after a long stay in intensive care, it is not a standard expectation. Many patients may be more subdued and fatigued rather than disruptive. D. Will state, "I am so relieved to be out of intensive care": While this response might occur, it is not guaranteed. Patients may have mixed emotions about their transition from intensive care, including anxiety or confusion. Therefore, this statement is not a definitive expectation during the mental status examination.
