A nurse is a healthcare professional who is trained to provide care and support to patients who are ill or injured. Nurses work in a variety of settings, including hospitals, clinics, long-term care facilities, and home healthcare. They are responsible for assessing patient needs, developing care plans, administering medications, monitoring vital signs, providing emotional support, and educating patients and their families about health and wellness. There are different levels of nursing, ranging from entry-level certified nursing assistants (CNAs) to advanced practice registered nurses (APRNs) with specialized training and education. Some of the different types of nurses include registered nurses (RNs), licensed practical nurses (LPNs), and nurse practitioners (NPs). Nurses play a crucial role in the healthcare system, working closely with doctors, other healthcare professionals, and patients to provide high-quality care and support. They are often the primary point of contact for patients, providing comfort and reassurance during a difficult time. Nurses also help to ensure that patients receive the appropriate care and treatment, working to prevent complications and promote recovery.
