Update 2026/2027 | 200 Questions and Verified Answers |
Rasmussen Complete Q&A Guide | A+ Graded
1. Pathophysiology is best defined as:
A. Study of normal body function
B. Study of structural changes in cells and tissues
C. Study of functional changes caused by disease
D. Study of drug actions on the body
Answer: C. Pathophysiology focuses on abnormal physiological processes resulting from disease. It
differs from anatomy (structure) and normal physiology (function). Pathophysiology includes four
components: etiology (causes), pathogenesis (disease development), clinical manifestations
(signs/symptoms), and treatment implications.
2. The term that describes the maintenance of a stable internal environment is:
A. Pathogenesis
B. Homeostasis
C. Etiology
D. Allostasis
Answer: B. Homeostasis refers to the body's ability to maintain internal equilibrium despite external
changes. Allostasis refers to the adaptive processes the body uses to achieve homeostasis, not the state
itself.
3. A disease that develops slowly and lasts for months or years is considered:
,A. Acute
B. Chronic
C. Latent
D. Nosocomial
Answer: B. Chronic diseases have prolonged courses (months to years), such as diabetes or
hypertension. Acute conditions develop rapidly and resolve quickly; latent refers to dormant periods;
nosocomial means acquired in healthcare settings.
4. The cause or origin of a disease is referred to as:
A. Pathogenesis
B. Etiology
C. Clinical manifestation
D. Prognosis
Answer: B. Etiology identifies the causal factors for disease (e.g., bacteria, genetics, environment).
Pathogenesis is the sequence of events leading to disease manifestations; prognosis predicts disease
outcome.
5. Which organelle is responsible for ATP production?
A. Nucleus
B. Ribosome
C. Mitochondrion
D. Golgi apparatus
,Answer: C. Mitochondria are the "powerhouses" of the cell, generating ATP through cellular respiration.
They contain their own DNA and are highly concentrated in energydemanding tissues like muscle and
brain.
6. Which organelle contains digestive enzymes that break down cellular debris?
A. Lysosome
B. Peroxisome
C. Endoplasmic reticulum
D. Nucleolus
Answer: A. Lysosomes contain hydrolytic enzymes that digest waste, pathogens, and damaged
organelles. Peroxisomes break down fatty acids and detoxify hydrogen peroxide.
7. Which cellular structure regulates the passage of substances into and out of the cell?
A. Cell membrane
B. Nuclear envelope
C. Cytoplasm
D. Mitochondrial membrane
Answer: A. The cell membrane (plasma membrane) is selectively permeable, controlling ion and
molecule transport via channels, carriers, and pumps.
8. What is the primary component of the cell membrane?
A. Carbohydrates
, B. Nucleic acids
C. Phospholipid bilayer
D. Proteins
Answer: C. The phospholipid bilayer forms the basic structure of the cell membrane, with hydrophilic
heads facing outward and hydrophobic tails facing inward.
9. Which type of cellular adaptation occurs when a cell decreases in size and function due to reduced
workload?
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
Answer: C. Atrophy is shrinkage from disuse, denervation, ischemia, or nutrient deficiency.
10. A patient with chronic hypertension develops thickening of the left ventricular wall. This is an
example of:
A. Atrophy
B. Hyperplasia
C. Hypertrophy
D. Metaplasia
Answer: C. Increased workload causes individual myocytes to enlarge (hypertrophy), not increase in
number.
