Which symptom is most consistent with anemia in chemotherapy patients?

• A. Fatigue and pallor
• B. Weight gain
• C. Hyperactivity
• D. Bradycardia

Answer: (A)

Anemia from chemotherapy reduces the blood’s oxygen-carrying capacity, so tissues receive less oxygen. That tissue hypoxia most clearly presents as fatigue and pallor, since energy production drops and skin color may appear pale due to fewer red blood cells. Weight gain, hyperactivity, or bradycardia don’t reflect this oxygen-delivery problem—anemia often triggers a compensatory increase in heart rate (tachycardia) to help maintain perfusion. So fatigue with pallor is the hallmark sign in this setting.
