CARE is a four-letter word that refers to the act of providing assistance and support to those in need. Tests is a five-letter word that refers to the process of examining a patient's health and diagnosing any medical conditions. NURSING is a seven-letter word that refers to the practice of providing medical CARE and treatment to patients. All of these activities are important components of hospital work.
