How does the author use foreshadowing in The Shrike?

The play opens with an illustration of the hospital's autocratic structure, which foreshadows what is in store for Jim as he struggles to retain his individuality. In the first scene, Miss Cardell, one of the authoritarian student nurses, accuses a patient of smoking, chastising him for endangering his weak heart. When Fleming refuses to admit that he has been smoking, Miss Cardell invades his privacy by looking under his covers for the cigarettes. Finally, when she tells him that she will have to call one of the attendants, he gives in. In an effort to guarantee that he will never again disobey orders, Miss Cardell tells him that she will report him. This opening vignette presents, in miniature, what Jim will experience during his stay in the hospital.
