Chronic lead exposure may cause which of the following nervous system problems?

• A. Memory loss
• B. Digestive problems
• C. High blood sugar
• D. Nerve disorders

Answer: (D)

Chronic lead exposure damages the nervous system by injuring the peripheral nerves, which can produce nerve disorders such as numbness, tingling, and weakness. Lead neuropathy is a classic result of prolonged exposure, reflecting direct nervous system injury from the toxin. While memory problems can occur with lead exposure as part of broader cognitive effects, and digestive symptoms or metabolic changes are not the primary nervous system manifestations, the direct and characteristic nervous system impact is best described by nerve disorders. Understanding that lead disrupts nerve signaling and nerve fiber function explains why this choice fits best.
