Final answer:
Hygiene measures for patients receiving external radiotherapy include minimizing time in the radiation environment, maintaining distance from the source, using shielding, and avoiding close contact with phones.
Step-by-step explanation:
When teaching a patient receiving external radiotherapy, several hygiene measures are usually emphasized to ensure safety and minimize potential risks:
- Minimize time spent in the radiation environment to reduce exposure.
- Maintain distance from the radiation source as much as possible as radiation intensity decreases with distance.
- Use shielding to protect against radiation by placing a barrier between the patient and the radiation source.
- Avoid phone use close to the body and in a car without an external antenna to decrease exposure to radiation.
These measures aim to limit radiation doses and protect both the patient and healthcare personnel.
