✍️ Sample RT Questions & Answers
1. Why is it important to monitor radiation exposure to the patient during therapy?
Monitoring radiation exposure to the patient during therapy is paramount to ensure their safety and prevent excessive radiation exposure. This continuous oversight helps the medical team adhere to the prescribed dose limits, protecting healthy tissues from unnecessary damage and reducing the risk of severe side effects. It is a critical component of quality assurance, ensuring the patient receives the optimal therapeutic benefit with minimal harm.
2. Why is it important for radiation therapists to assess the patient's physical condition before treatment?
Assessing a patient's physical condition before radiation treatment is crucial to ensure they can safely tolerate the therapy. This evaluation helps identify any pre-existing conditions or vulnerabilities that might be exacerbated by radiation or affect their ability to remain still during treatment. It allows the care team to make necessary adjustments or provide supportive care to optimize patient safety and treatment efficacy.
3. The Bergonié-Tribondeau law states that cells are MORE radiosensitive when they:
The Bergonié-Tribondeau law (1906) states that cells with high mitotic activity, great proliferative future, and less differentiation are more radiosensitive — which is why cancer cells are generally more sensitive than mature normal cells.
4. What is the standard of care requirement for patient communication in clinical practice?
The standard of care is defined as what a reasonably competent practitioner with similar training would provide under similar circumstances.
5. Which cell cycle phase is considered MOST radioresistant?
Late S phase is the most radioresistant phase of the cell cycle because cells are actively synthesizing DNA and have increased repair capacity through homologous recombination.
6. What is the standard of care requirement for clinical assessment methods in clinical practice?
The standard of care is defined as what a reasonably competent practitioner with similar training would provide under similar circumstances.
