Which category would involve decreased WBCs, RBCs, and platelets?

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

Answer: (D)

This question tests understanding of where bone marrow suppression shows up as a side effect. When a drug slows or stops production in the bone marrow, all blood cell lines can drop, leading to decreased white blood cells, red blood cells, and platelets. This pattern is called hematologic toxicity. WBCs fight infection, RBCs carry oxygen, and platelets help with clotting, so reductions in all three can cause infection risk, fatigue from anemia, and easy bruising or bleeding. That’s why this category is hematology side effects—it's about effects on blood cell production rather than the GI tract, CNS, or urinary system. In practice, clinicians monitor CBCs and watch for signs of infection, anemia symptoms, and bleeding.
