In addition, I would suggest you pull from other aspects of your life outside of shadowing (extracurriculars, jobs, volunteer work, academics, etc.). The essay is an opportunity for you to shine, so mention some of the things you've done that coincide with the APTA's values of professionalism to really show that you're prepared to exhibit professionalism as a PT student. Remember, answer the question above all...professionalism as a PT student, not a therapist. If you have space, then you could definitely add in how you plan to exhibit professionalism as a therapist, but you don't want to shy too far away from the prompt 🙂
