Study Notes

Exam 3 Review Topics

Exam 3 covers chapters 9, 19, 7, 18, and 20 of the textbook, specifically focusing on applied pathophysiology.

Chapter 9: Altered Acid-Base Balance

Understand acidosis and alkalosis identification via serum (blood) pH levels.
Know the importance of maintaining physiologic pH for cellular and tissue function.
Identify the three buffer systems in the body and their mechanisms for maintaining pH balance.

Chapter 19: Degenerative Changes in Aging

Compare normal aging to pathophysiological changes.
Understand the various manifestations of aging (refer to Figure 19.2 in the textbook).
Learn about osteoporosis and Alzheimer's disease as examples of aging-related conditions.

Chapter 7: Altered Cellular Proliferation and Differentiation

Differentiate between proliferation and differentiation, especially in relation to cancer.
Define cancer and neoplasms, and recognize the characteristics of neoplastic cells.
Explain carcinogenesis and the role of genetic mutations.
Identify factors that create a favorable environment for cancer formation (e.g., polymorphisms, epigenetic changes).
Understand the concept of initiation, promotion, and progression in cancer development.
Recognize characteristics of cancer cells, e.g., autonomy, anaplasia, changes in cell-to-cell communication, alterations in energy needs, and changes in cohesion and mobility.
Differentiate between benign and malignant cancers.
Understand methods of cancer spread.
Understand basics of naming and classifying cancers; whether higher numbers indicate better or worse prognosis.
Discuss general and localized manifestations of cancer.
Describe cancer diagnostics and treatments.
Note examples of cancer types, including lung, brain, colon, leukemia, and lymphomas.

Chapter 18: Altered Elimination

Explain the process of urine production and removal, including nephron function (glomerulus).
Describe the kidneys' roles in reabsorption and excretion.
Outline how urine is transported from the kidneys to the outside of the body.

Chapter 20: Integrated Pathophysiologic Concepts (Glucose Regulation and Diabetes)

Understand the role of glucose, energy, insulin, and the pancreas in regulating blood sugar levels.
Know what happens when the blood sugar regulating system malfunctions; specifically relevant to type 1, type 2, and gestational diabetes.
Describe causes, symptoms, diagnostics, and treatments for each type of diabetes, including non-pharmacological approaches.
Discuss the long-term complications of diabetes (microvascular and macrovascular).
Understand the dangers of hypoglycemia (low blood sugar).
Define diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar nonketotic syndrome (HHNK).
Learn about the Somogyi effect and dawn phenomenon.
Review important diagnoses like metabolic acidosis and osteoporosis.

General Studying Advice

Use a combination of textbook, notes, pre-lecture study guides, and online videos during your study process.
Create visual aids (concept maps) if visual learning helps you.
Use the provided brain-based learning techniques.
Focus on the body's expected functions and how these can be disrupted (pathophysiology) in each chapter.
Do not solely rely on powerpoints, but try to supplement them with class notes and readings.
Note the concepts in the main topics of the review and think about the main foundational concepts.
Understand examples of real diagnoses, how their pathophysiology, signs, symptoms, diagnostic tests, and treatment/management.
