Which of the following would you expect to encounter in a patient with moderate radiation toxicity?

• A. Nausea and vomiting
• B. Headache and dizziness
• C. Hair loss and first-degree burns
• D. Rash and joint pain

Answer: (C)

Radiation toxicity at a moderate level usually shows localized skin reactions in the area that received radiation, reflecting effects on the rapidly dividing cells of the skin and hair follicles. Hair loss in the irradiated region happens because hair follicles are highly sensitive to radiation. First-degree burns describe superficial epidermal damage with mild redness, which is also a typical skin reaction to moderate radiation exposure. Together, these signs directly reflect a moderate, localized skin-tissue response to radiation. Nausea and vomiting tend to occur with higher, more systemic radiation doses affecting the GI tract; headache and dizziness are nonspecific symptoms not characteristic of a defined radiation-toxicity pattern; and rash with joint pain isn’t a classic presentation of radiation injury to the skin.
