Health assessment is the systematic process of gathering comprehensive data about a patient’s physical and psychosocial status to guide care. This text teaches head-to-toe examination techniques, focused assessments, and effective history taking across the lifespan. Each chapter pairs normal findings with common deviations and explains their clinical significance and next steps. Communication skills, cultural considerations, and documentation templates support patient-centred assessments. Clinical photographs, stepwise examination checklists, and quick reference tables make it a practical companion in training and clinics. Suitable for nursing students and early-career nurses, it builds confidence for competent, holistic patient appraisal.
