NURS 4322 FINAL EXAM STUDY GUIDE TOPICS – TAMUCC NURSING REVIEW,
PRACTICE QUESTIONS & PREP 2026/2027
Types of Prevention
Levels of Prevention
Primary Prevention: Focuses on preventing disease before it occurs through health promotion
and education. Examples include vaccinations and lifestyle modifications.
Secondary Prevention: Involves early detection and intervention to prevent disease progression.
Screening tests like mammograms and blood pressure checks are key examples.
Tertiary Prevention: Aims to reduce the impact of an already established disease by managing
symptoms and preventing complications. Rehabilitation programs are a prime example.
Importance of Prevention
Prevention strategies can significantly reduce healthcare costs by avoiding the need for more
extensive treatments.
Public health initiatives often focus on prevention to improve community health outcomes and
reduce disease burden.
Education and awareness campaigns are crucial in promoting preventive measures among
populations.
Pathophysiology Concepts
Etiology and Pathogenesis
Etiology: Refers to the cause or origin of a disease, which can be genetic, environmental, or
infectious.
Pathogenesis: Describes the biological mechanism that leads to the development of a disease,
including cellular and molecular changes.
Understanding both concepts is essential for developing targeted treatments and preventive
strategies.
Clinical Manifestations
Clinical manifestations are the signs and symptoms associated with a disease, which can vary
widely among individuals.
Examples include fever, pain, and fatigue, which can indicate underlying pathophysiological
processes.
Recognizing these manifestations is critical for timely diagnosis and intervention.
Respiratory and Cardiovascular Systems
Respiratory Conditions
Respiratory Alkalosis: A condition characterized by decreased carbon dioxide levels due to
hyperventilation, leading to increased blood pH.
Pneumothorax: The presence of air in the pleural space, which can lead to lung collapse. Types
include spontaneous, traumatic, and tension pneumothorax.
Pulmonary Embolism: A blockage in a pulmonary artery, often due to blood clots, which can
cause sudden shortness of breath and chest pain.
Cardiovascular Dynamics
Cardiac Output: The volume of blood the heart pumps per minute, calculated as heart rate
multiplied by stroke volume.
Systole and Diastole: Systole refers to the contraction phase of the heart, while diastole is the
relaxation phase, both crucial for effective circulation.
Cardiac Preload and Afterload: Preload is the initial stretching of the cardiac muscle fibers, while
afterload is the resistance the heart must overcome to eject blood.
