Definition of Nursing: Discuss the critical role of nursing in modern healthcare, from patient care to public health advocacy

Nursing integrates the art and science of caring and focuses on the protection, promotion, and optimization of health and human functioning; prevention of illness and injury; facilitation of healing; and alleviation of suffering through compassionate presence. It is a profession that demands both emotional intelligence and scientific knowledge. Nursing is the diagnosis and treatment of human responses and advocacy in the care of individuals, families, groups, communities, and populations in recognition of the connection of all humanity. This holistic approach ensures that care is not only individualized but also inclusive of broader societal needs.

21st Century Nursing
21st Century nursing is the glue that holds a patient’s health care journey together. Nurses are often the first point of contact for patients, providing both medical and emotional support. Across the entire patient experience, and wherever there is someone in need of care, nurses work tirelessly to identify and protect the needs of the individual. Their role extends beyond the hospital, influencing public health policies and community health initiatives.

Beyond the time-honored reputation for compassion and dedication lies a highly specialized profession, which is constantly evolving to address the needs of society. Technological advancements and new medical research continually reshape the nursing landscape. From ensuring the most accurate diagnoses to the ongoing education of the public about critical health issues; nurses are indispensable in safeguarding public health. Their ability to adapt to new challenges is a testament to the resilience and versatility of the profession.

Nursing as an Art and Science
Nursing can be described as both an art and a science; a heart and a mind. At its heart, lies a fundamental respect for human dignity and an intuition for a patient’s needs. This emotional connection is what sets nursing apart from other medical professions. This is supported by the mind, in the form of rigorous core learning. Due to the vast range of specialisms and complex skills in the nursing profession, each nurse will have specific strengths, passions, and expertise. These unique qualities allow nurses to tailor their care to meet the diverse needs of their patients.

However, nursing has a unifying ethos: In assessing a patient, nurses do not just consider test results. They also take into account the patient’s personal history, lifestyle, and emotional state. Through the critical thinking exemplified in the nursing process (see below), nurses use their judgment to integrate objective data with subjective experience of a patient’s biological, physical and behavioral needs. This ensures that every patient, from city hospital to community health center; state prison to summer camp, receives the best possible care regardless of who they are, or where they may be. This patient-centered approach is the cornerstone of modern nursing practice.

What Exactly Do Nurses Do?
In a field as varied as nursing, there is no typical answer. Responsibilities can range from making acute treatment decisions to providing inoculations in schools. The key unifying characteristic in every role is the skill and drive that it takes to be a nurse. Nurses must possess a unique combination of technical expertise and interpersonal skills. Through long-term monitoring of patients’ behavior and knowledge-based expertise, nurses are best placed to take an all-encompassing view of a patient’s wellbeing. This comprehensive perspective allows nurses to identify potential health issues before they become critical.

Types of Nurses
All nurses complete a rigorous program of extensive education and study, and work directly with patients, families, and communities using the core values of the nursing process. In the United States today, nursing roles can be divided into three categories by the specific responsibilities they undertake. Each category requires a unique set of skills and knowledge, reflecting the diversity of the nursing profession.

Registered Nurses
Registered nurses (RN) form the backbone of health care provision in the United States. RNs provide critical health care to the public wherever it is needed. Their role is essential in both acute and chronic care settings.

Key Responsibilities

• Perform physical exams and health histories before making critical decisions
• Provide health promotion, counseling and education
• Administer medications and other personalized interventions
• Coordinate care, in collaboration with a wide array of health care professionals

Advanced Practice Registered Nurses
Advance Practice Registered Nurses (APRN) hold at least a Master’s degree, in addition to the initial nursing education and licensing required for all RNs. The responsibilities of an APRN include, but are not limited to, providing invaluable primary and preventative health care to the public. APRNs treat and diagnose illnesses, advise the public on health issues, manage chronic disease and engage in continuous education to remain at the very forefront of any technological, methodological, or other developments in the field. Their advanced training allows them to take on roles that were traditionally reserved for physicians.

APRNs Practice Specialist Roles

• Nurse Practitioners prescribe medication, diagnose and treat minor illnesses and injuries
• Certified Nurse-Midwives provide gynecological and low-risk obstetrical care
• Clinical Nurse Specialists handle a wide range of physical and mental health problems
• Certified Registered Nurse Anesthetists administer more than 65 percent of all anesthetics

Licensed Practical Nurses
Licensed Practical Nurses (LPN), also known as Licensed Vocational Nurses (LVNs), support the core health care team and work under the supervision of an RN, APRN or MD. By providing basic and routine care, they ensure the wellbeing of patients throughout the whole of the health care journey. Their role is crucial in maintaining the day-to-day operations of healthcare facilities.

Key Responsibilities

• Check vital signs and look for signs that health is deteriorating or improving
• Perform basic nursing functions such as changing bandages and wound dressings
• Ensure patients are comfortable, well-fed and hydrated
• May administer medications in some settings

The Nursing Process
No matter what their field or specialty, all nurses utilize the same nursing process; a scientific method designed to deliver the very best in patient care, through five simple steps. This process ensures that care is systematic, patient-centered, and evidence-based.

Assessment – Nurses assess patients on an in-depth physiological, economic, social and lifestyle basis. This comprehensive evaluation helps identify both immediate and long-term health needs.
Diagnosis – Through careful consideration of both physical symptoms and patient behavior, the nurse forms a diagnosis. This step requires critical thinking and clinical expertise.
Outcomes / Planning – The nurse uses their expertise to set realistic goals for the patient’s recovery. These objectives are then closely monitored. The planning phase ensures that care is tailored to the individual’s unique circumstances.
Implementation – By accurately implementing the care plan, nurses guarantee consistency of care for the patient whilst meticulously documenting their progress. This step involves collaboration with other healthcare professionals.
Evaluation – By closely analyzing the effectiveness of the care plan and studying patient response, the nurse hones the plan to achieve the very best patient outcomes. Continuous evaluation is key to improving patient care over time.

Nurses are Key to the Health of the Nation
There are over 4 million registered nurses in the United States today. That means that one in every 100 people is a registered nurse. Nurses are in every community – large and small – providing expert care from birth to the end of life. Their presence is vital in both urban and rural settings, ensuring that healthcare is accessible to all.

According to the January 2012 “United States Registered Nurse Workforce Report Card and Shortage Forecast” in the American Page Essay – Journal of Medical Quality, a shortage of registered nurses is projected to spread across the country between 2009 and 2030. In this state-by-state analysis, the authors forecast the RN shortage to be most intense in the South and the West. This shortage highlights the need for increased investment in nursing education and workforce development.

Nurses’ roles range from direct patient care and case management to establishing nursing practice standards, developing quality assurance procedures, and directing complex nursing care systems. Their contributions extend beyond the bedside, influencing healthcare policy and improving the overall quality of care.
