Thesis quantitative research

Good afternoon, I am struggling on my quantitative research proposal, it is dealing with a PICO of pediatric population in a hospital setting and the use of a procedural treatment room versus the patient's bedside during hospitalization during and the affect it has on the fear/anxiety level.
I am trying to place my finger on the research design plan:I looked towards descriptive observational, however, it is some intervention by moving a patient to a treatment room for the procedure. Therefore, what design method can i try to select: I tried picking cross-sectional or randomized clinical trial.
I am completely stuck: thanks for any guidance.
