• A. Mild fatigue
• B. Slight nausea
• C. Mild headache
• D. Fever, severe shortness of breath, chest pain, severe dehydration, or signs of anaphylaxis or infusion reaction

Answer: (D)

Recognizing red-flag symptoms that require urgent evaluation in chemotherapy patients. Fever with severe shortness of breath, chest pain, severe dehydration, or signs of anaphylaxis or an infusion reaction signal potentially life-threatening emergencies. In chemotherapy, the immune system is often suppressed, so fever can be the first sign of a serious infection that can progress rapidly—an oncologic emergency that needs immediate assessment and prompt workup and treatment. Severe shortness of breath with fever or chest pain could indicate pneumonia, pulmonary embolism, or cardiopulmonary complications from therapy, all demanding rapid assessment. Signs of anaphylaxis or an infusion reaction require immediate intervention to protect the airway and stabilize breathing and circulation, plus stopping the offending agent and treating the reaction. When these symptoms appear, urgent care is necessary rather than waiting for routine monitoring. By contrast, mild fatigue, slight nausea, or mild headache are common, non-emergency effects that can be monitored and managed with standard supportive care unless they worsen or are accompanied by red-flag signs.
