In making a Drug Study, the following elements must be present: Generic Name and the Brand name (not all brands, just the brand used by the patient), Action, Indication, Pregnancy Category, Drug Classification, and Contraindication, Adverse Effect, Drug interaction and Nursing Consideration/Intervention…. Most clinical instructors preferred this to be in a long bond paper in printed or handwritten with paper in landscape.
