Skilled nursing care is used to manage, observe and evaluate care. Registered nurses (RN) and licensed practical nurses (LPN) provide skilled services that cannot be performed safely and effectively by nonprofessional personnel. Some of these services include injections and intravenous therapy, wound care, education on disease treatment and prevention and patient assessments. The intricacy of a patient’s medical condition and required course of treatment determine whether care should be provided by an RN or provided by an LPN. The nurse is also the link between the patient, their family and the physician. The patient’s primary physician approves the orders for ongoing home health care and the plan of treatment which can be performed at home, in an assisted living facility or in a family member’s home.
