A nurse is performing a monofilament sensory assessment of a client who has diabetes mellitus. When performing this assessment, for which of the following complications is the nurse monitoring?

Choice A reason: Retinopathy involves damage to the retinal blood vessels and is assessed through ophthalmologic exams, not monofilament testing. Choice B reason: Neuropathy, specifically peripheral sensory neuropathy, is the target of monofilament testing. This assessment checks for loss of protective sensation in the feet, which increases the risk of ulcers and amputations in diabetic patients. Choice C reason: Radiculopathy refers to nerve root compression, often in the spine, and presents with radiating pain. It is not assessed using monofilament testing. Choice D reason: Nephropathy involves kidney damage and is monitored through laboratory tests such as serum creatinine and urine albumin levels, not sensory assessments.
