    A 75-year-old client with a recent history of a cerebrovascular accident (CVA) presents with right hemiparesis. The nurse tests the deep tendon reflexes on the right side and elicits a brisk 4+ response. Which interpretation of this finding is accurate?

    Explanation & Rationale

    A. An absent or sluggish deep tendon reflex typically indicates a lower motor neuron lesion, which affects the peripheral nerves or spinal cord segments involved in reflex arc processing. Lower motor neuron lesions often result in reduced or absent reflexes, not brisk responses. B. Flaccid paralysis is characterized by a lack of muscle tone and reflexes, which is usually associated with lower motor neuron damage. A brisk 4+ reflex response does not indicate flaccid paralysis but rather heightened reflex activity. C. A brisk 4+ response indicates hyperactivity of the deep tendon reflexes, which is consistent with an upper motor neuron disorder. Upper motor neuron lesions, such as those resulting from a cerebrovascular accident (CVA), often lead to increased reflex responses due to disruption in the normal inhibitory signals from the brain. D. A normal reflex response is typically classified as 2+ on a scale of 0 to 4, where 2+ is considered average or expected. A 4+ response indicates hyperactivity, which is not normal but rather indicates increased reflexes, usually associated with upper motor neuron issues.
