There are nursing stations in every medical center in the Directorate. Over 55 nurses with different academic levels, all certified by the Lebanese Ministry of Health, make up the nursing team. The Nursing pyramid consists of the Nursing Supervisor, In charge Nurse, Registered Nurses (RN), Practical Nurses (PN) and Dental Assistance Nurses. The supervisor is responsible for the management of the nursing care of the patients and the supervision of the nursing personnel assigned to all the centers. She plans, coordinates, provides, and evaluates patients on her unit. In addition, she attends all the workshops and seminars done in the Health Ministry. She attends the conferences invited from Medical Hospitals and other health dispensaries. She also attends and organizes meetings done for her nurses in the Directorate of Health and Social Services. The Registered Nurse is considered the In charge and the Triage Nurse who has the main load in each center. Her duties include welcoming and guiding the patient within the center, performing nursing treatment, administering medications and injections, and withdrawing blood test samples. The RN also has the responsibility of admitting and discharging patients, giving routine educational sessions and attending conferences to constantly be updated on latest health issues. She does filing and screening through an in-house developed computer program. She practices the Soap System with each patient (Assessment, Observation, Implementation, Planning, and Evaluation). The RN is also involved in the School Health Program and Staff Development Department.
