The nurse is caring for a client who requires occupational therapy. Which question asked by the nurse would be most appropriate when assessing a client for the sensory perception of stereognosis?

Stereognosis is the cortical ability to recognize objects through tactile perception without visual input, mediated by the parietal lobe. Impairment indicates dysfunction in sensory integration, somatosensory pathways, or cortical processing affecting object identification and spatial discrimination. Rationale: A. Olfactory perception relates to smell detection mediated by cranial nerve I and olfactory cortex. It assesses chemosensory function rather than tactile recognition. Therefore smell dysfunction does not evaluate stereognosis or somatosensory cortical processing. B. Verbal communication assesses language and speech function involving Broca’s and Wernicke’s areas. It reflects expressive or receptive aphasia rather than tactile sensory perception. Thus language assessment is unrelated to stereognosis evaluation. C. Gustatory perception evaluates taste sensation mediated by cranial nerves VII, IX, and X. It is a chemosensory function unrelated to tactile object recognition. Therefore taste dysfunction does not assess stereognosis capability. D. Object recognition without visual input directly evaluates stereognosis by testing the client’s ability to identify items through touch alone. This requires intact somatosensory pathways and cortical integration. Thus tactile identification is the correct method for assessing stereognosis.
