Which of the following are documented by the therapist at the end of the treatment?

The correct answer is that the therapist documents all of the above at the end of the treatment. Documenting the daily fraction dose is essential for maintaining an accurate record of the treatment regimen being administered, which is crucial for both patient safety and treatment planning.

Recording any unusual occurrences is equally important, as it provides insights into the patient’s response to treatment and can highlight any potential side effects or complications that may need further attention or intervention.

The time of arrival is also documented to track patient attendance, ensure proper scheduling, and assist in managing the workflow within the clinical setting.

Therefore, it's necessary for therapists to maintain comprehensive and accurate records that include all these elements to uphold quality standards in patient care and compliance with professional guidelines.
