Question 1

Which unit of measurement quantifies the absorbed radiation dose in modern oncology practice?

Accepted Answer

Gray (Gy)

Answer

The Gray (Gy) is the SI unit of absorbed radiation dose, equal to 1 joule of energy absorbed per kilogram of tissue.

Question 2

Radiation-induced mucositis in the oral cavity is best managed with:

Accepted Answer

Frequent saline rinses, pain assessment, and nutritional support

Answer

Saline rinses maintain oral hygiene, regular pain assessment guides analgesic escalation, and nutritional support prevents the weight loss associated with mucositis.

Question 3

Radiation recall is defined as:

Accepted Answer

Inflammatory reaction at a prior radiation site triggered by a systemic drug

Answer

Radiation recall is a cutaneous or mucosal inflammatory reaction at a previously irradiated field, triggered by a systemic agent (commonly anthracyclines or taxanes) administered after radiation.

Question 4

Which skin care instruction is correct for patients undergoing external beam radiation therapy to the breast?

Accepted Answer

Avoid tight clothing, heat, and sun exposure; use gentle fragrance-free moisturizers

Answer

Protecting irradiated skin from friction, heat, and UV while maintaining moisture with gentle products reduces the severity of radiation dermatitis.

Question 5

Stereotactic body radiation therapy (SBRT) differs from conventional radiation by delivering:

Accepted Answer

Very high doses per fraction in a small number of treatments with precise targeting

Answer

SBRT delivers ablative doses (typically 5–20 Gy/fraction) in 1–5 fractions with submillimeter precision, maximizing tumor cell kill while sparing surrounding tissue.
