A client with diabetic peripheral neuropathy has been taking pregabalin for 4 days. Which finding indicates to the nurse that the medication is effective?

Rationale: A. Full volume of pedal pulses: Pedal pulses reflect peripheral arterial circulation, not neuropathic pain. Pregabalin does not affect vascular flow, so this finding is unrelated to the medication’s intended effect. B. Reduced level of pain: Pregabalin is an anticonvulsant used to treat neuropathic pain by modulating nerve signals. A reduction in reported pain confirms that the medication is helping manage the client’s diabetic nerve pain. C. Granulating tissue in foot ulcer: Wound healing is influenced by infection control, circulation, and blood glucose management—not directly by pregabalin. While important, this finding does not measure the drug’s effectiveness for neuropathy. D. Improved visual acuity: Visual changes are not treated with pregabalin and may be associated with diabetic retinopathy. Pregabalin does not improve vision and is not indicated for ocular complications of diabetes.
