1. Introduction to Nursing
Definition and Scope
Nursing is a fluid and multi-faceted occupation that has the goal of helping persons, families
and communities to maintain health and well-being. Nurses are employed in numerous
different roles in numerous facilities such as hospitals, clinics, nursing homes and community
health. Nursing interventions also encompass health promotion and illness prevention, as
fundamental and complex care of individuals with acute and chronic health conditions.
Historical Background
The nursing profession has developed through the many centuries which have passed.
Originally, nursing was a kind of innate, inexperienced care offered by families or religious
congregations to the sick and their households. Forces that help shape the current practice
of nursing have ancestral icons; some of them include Florence Nightingale.
Nursing Roles and Responsibilities
Nurses perform a wide range of tasks, including:
Performance evaluation – patient’s state and requirements
Formulation of care plans and putting them into practice
Providing medications and courses of treatment
Teaching of patients and family members
Regarded the interaction with other healthcare givers
2. Importance of Medical Terminology
Role in Effective Communication
There is no doubt that medical terminology is a very important tool for general and efficient
communication amongst members of the health care team. It is always helpful to use
standard words for the purpose for which they are designed so that any message passed on
is technically clear. This is important particularly when planning and organizing patient care,
recording and reporting the details of a patient’s history as well as sharing some issues with
other health care providers.
Enhancing Professionalism
Since a large amount of information is conveyed in the healthcare profession by medical
terminology, implementation and proper understanding of medical terms add to
professionalism and make one more credible in his/her field. It is a prestigious signifying a
nurse’s training background and his/her zeal to work exclusively for his/her clients.
Dominance in terminology also enables doctors and other healthcare professionals to carry
on learning and applying new findings in medical science.
Impact on Patient Care
Concisely, using correct medical terms tremendously contributes to patient care for the
following reasons: This assists in coming up with a constant and efficient methodology for
handling patients.
3. Basic Medical Terminology
Root Words
Root words are units of dimensionally bigger meaning in the expression of diseases or some
states of a body, and as a rule, they give their main meaning to the term. Examples include:
Cardi (heart)
Neur (nerve)
Gastr (stomach)
Prefixes and Suffixes
Prefixes and suffixes modify the meaning of root words:
Prefix: It is a term that is placed before the root word and the root must be changed to
retain its meaning (for example, Hyper meaning too much)
Suffix: Word part that is attached to the base word or root word, to provide more
information (for instance, -itis for inflammation).
Combining Forms
Combining forms are root words joined with a vowel to interact with other words or actual
endings. For example:
Hemat/o (blood) added to -logy (study) gives the meaning of Hematology (meaning: the
study of blood).
4. Anatomy and Physiology Terminology
Body Systems
It is expedient for anybody who wants to study anatomy and physiology to establish some
basic knowledge of the language associated with the core systems of the human body.
Major body systems include:
Circulatory System: Heart, Blood vessels
Respiratory System: Lungs trachea
Digestive System: Stomach intestinal
The structure of the terms used to describe the position and limbed directions
Anatomical terms describe the location of body parts relative to one another:
Anterior: Front
Posterior: Back
Superior: Above
Inferior: Below
Medical Abbreviations
It is worth noting that abbreviations are commonly used in medical records and medical
communication. Examples include:
BP: Blood Pressure
HR: Heart Rate
WBC: White Blood Cell
5. Pathophysiology Terminology
Disease Processes
Understanding disease processes involves learning terms related to how diseases affect the
body:
Etiology: Usually in the diagnosis of a disease, one is asked to determine the cause of
the disease.
Pathogenesis: Negotiating a disease: the cultural creation of a disease
Prognosis: A probable or anticipated development of an illness or disease
Common Diseases and Conditions
Familiarity with common diseases and their terms helps in diagnosing and treating patients:
Diabetes Mellitus: The state of the body in which there exists an excess of glucose in
the bloodstream
Hypertension: Hypertension
Asthma: A more than characteristically long-term respiratory disease
Medical Procedures and Tests
Terms related to medical procedures and tests are crucial for understanding diagnostic
processes:
Biopsy: Bipolar cautery of tissue for biopsy
Endoscopy: Endoscopy or the examination of the internal organs through a tube.
MRI: Otherwise commonly known as MRI, or Magnetic Resonance Imaging.
6. Pharmacology Terminology
Drug Classification
Drugs are classified based on their effects and usage:
Analgesics: Analgesia (e. g. , Acetaminophen)
Antibiotics: Antibacterial chemicals such as antibiotic medications (e.g., Amoxicillin).
Antihypertensives: Anti-hypertension medications (e.g., Lisinopril).
Routes of Administration
Different routes for administering medication include:
Oral: Given orally
Intravenous (IV): Given through a drip
Topical: When used externally
Dosage and Administration Terms
Terms related to dosage and administration are essential for proper medication
management:
Dosage: The dosage of fluid prescribed
Frequency: Frequency at which certain medication should be administered
Side Effects: Side effects of a substance used in the treatment of a particular disease
7. Nursing Practice Terminology
Nursing Diagnosis and Interventions
Nursing diagnoses identify patient problems and guide interventions
Diagnosis: An assessment of a patient’s responses as per clinical insight (e.g., Acute
Pain)
Intervention: Measures employed to attend to diagnoses (e.g., Pain Management).
Care Planning
Care planning involves developing a comprehensive plan to address patient needs:
Goals: Goals of care
Implementation: Implementation of care plans
Evaluation: Methods of determining the effectiveness of the interventions that have
been implemented
Documentation Terms
Accurate documentation is crucial for patient care and legal purposes:
SOAP Notes: A way of noting down patient information that entails, history, findings,
analysis, and strategy.
Charting: Documentation of patients' records and treatment given
8. Specialty Areas in Nursing
Terms Used in Pediatrics
Pediatric nursing focuses on the care of children:
Pediatrics: The medical speciality that enclosed the examination of children
Growth and Development: Visually tracking the physical and emotional development of
the child
Terms Used in Geriatrics
Geriatric nursing addresses the needs of elderly patients:
Geriatrics: The medical speciality in charge of the health of the elderly
Age-Related Conditions: Miscellaneous conditions commonly seen in the aged
population include for example osteoporosis.
There are many terms used in mental health nursing, some of which are listed below:
Mental health nursing involves caring for patients with mental health conditions:
Psychiatric Disorders: Illnesses ( e.g., Depression, Schizophrenia)
Therapeutic Interventions: Services to promote well-being (e.g., Therapy, Prescribed
Drugs).
9. Cunningham provides a set of clinical scenarios and case studies in the book.
The Chapter, Medical Terminology in Practice
But to emphasize the fact that medical terms are used in everyday practice, case studies will
be described. For example:
Case Study 1: A patient with Diabetes Mellitus presents with symptoms
of Hyperglycemia.
Case Study 2: Management of a patient with Chronic Obstructive Pulmonary Disease
(COPD). Learning Objectives Upon completion of this subject, the learner should be able
to: Understand the nursing care, diagnosis, management and prognosis of a patient
with COPD. Pre-Reading Checklists is a self-assessment tool used to gauge the learner's
prior knowledge of COPD and its management before embarking on a case study
Common Clinical Scenarios
Common scenarios help in understanding the application of terminology:
Emergency Situations: Taking care of critical ailments such as Myocardial Infarction.
Chronic Conditions: Chronic disease management; for example Hypertension.
Case Study Analysis
Analyzing case studies helps in applying knowledge:
Assessment: From case studies, recognize important problems.
Diagnosis and Planning: Create right care plans out of the findings in the case.
Evaluation: Discuss and reflect on the results and make changes as desirable.
