Rationale: Graphesthesia is the ability to recognize the form of written symbols. The nurse can assess for this by tracing symbols, such as numbers, in the client's palm. "Identify three objects placed in the hand, one at a time" tests for stereognosis, which is the ability to identify the form of common objects using the sense of touch. "Identify the smallest distance between two skin pricks after pricking the skin with two pins at varying distances" and "state whether one or two skin pricks are felt, after applying sharp stimuli bilaterally to symmetrical areas of the client's skin" test for extinction phenomenon and two-point stimulation, respectively.
