Which category involves adverse effects on the kidneys and electrolyte balance, such as high potassium and BUN changes?

• A. Hematology side effects
• B. Urinary system side effects
• C. GI side effects
• D. CNS side effects

Answer: (B)

The kidneys are the organs that regulate fluid, electrolytes, and waste. When a drug affects renal function, you see electrolyte disturbances such as hyperkalemia and changes in BUN. BUN rises when the kidneys can’t clear waste effectively, and potassium levels can climb if the kidneys don’t excrete it properly. This pattern points to adverse effects in the urinary system, i.e., renal/urinary toxicity. Other categories relate to different body systems: hematology involves blood cells, GI involves the digestive tract, and CNS involves the brain and nerves, none of which are primarily about kidney function or electrolyte balance.
