An OTA is assessing sensory function in a client's hand. The OTA is assessing to see if the client can discriminate pressure and recording the smallest-diameter touch that the client can report sensing while her vision is occluded. Which assessment is the OTA performing on this client?

The OTA is performing the Semmes Weinstein monofilament test, which is used to determine the client's ability to discriminate pressure. The test involves the use of a series of nylon monofilaments of varying diameters that are applied to the client's skin until they bend. The smallest diameter monofilament that the client can detect is recorded as the threshold value for that area of the body. This test is especially useful for assessing diabetic neuropathy. The two-point test is used to assess the client's ability to discriminate between two points of pressure, while the Moberg pickup test is used to assess the client's ability to identify and pick up small objects. The sharp-dull discrimination test is used to assess the client's ability to differentiate between sharp and dull stimuli.
