A nurse is assessing cognitive functioning of a patient. Which action will the nurse take?

Choice A reason: Asking the family about normal behavior provides subjective context but lacks standardized cognitive assessment. Cognitive function requires objective tools like the MMSE to evaluate memory, orientation, and attention. Relying solely on family input risks missing subtle deficits, delaying diagnosis of conditions like dementia or delirium critical for patient management. Choice B reason: Asking for name, location, and month tests orientation, a component of cognitive assessment, but is too limited. The MMSE offers a comprehensive evaluation of memory, language, and visuospatial skills. This narrow approach risks overlooking broader cognitive impairments, potentially missing early dementia or other neurological conditions requiring targeted interventions. Choice C reason: The HHIE-S assesses hearing impairment, not cognitive function. Hearing loss may affect communication but isn’t a direct cognitive measure. Using this tool for cognition misdirects assessment, risking failure to identify cognitive deficits like memory loss, delaying diagnosis and management of conditions such as Alzheimer’s disease or acute confusional states. Choice D reason: Administering the MMSE is a standardized, comprehensive tool to assess cognitive function, evaluating orientation, memory, attention, language, and visuospatial skills. It detects impairments in conditions like dementia or delirium, guiding diagnosis and treatment. Its structured approach ensures reliable identification of cognitive deficits, critical for planning care and interventions in clinical settings.
