This pocket-sized clinical companion is designed to assist in the assessment of psychiatric nursing clients, formulation of nursing diagnoses, and design of psychiatric nursing care plans. It provides quick and easy access to the detailed and concrete information students need to know as they visit the inpatient unit, community mental health setting, or home care setting. The content is clinically based, rather than theory based. This avoids repetition of material that students already have in their mental health nursing textbooks and makes it a perfect reference for clinical use.
