1. Which statement best describes pathophysiology?
A. The study of medication administration
B. The study of abnormal physiological processes associated with
disease or injury
C. The study of nursing interventions only
D. The study of normal human anatomy
Answer: B. The study of abnormal physiological processes associated
with disease or injury
Rationale: Pathophysiology examines how normal physiological
functions are altered by disease or injury. It provides the scientific
,foundation for understanding clinical manifestations, disease
progression, and appropriate nursing interventions.
2. Homeostasis refers to:
A. Permanent changes in body structure
B. The body's ability to maintain a stable internal environment
C. Cell destruction following injury
D. The production of antibodies
Answer: B. The body's ability to maintain a stable internal
environment
Rationale: Homeostasis is the maintenance of relatively constant
internal conditions despite external changes. Regulatory systems,
including the nervous and endocrine systems, continuously adjust
physiological processes to preserve balance.
3. Which organelle is primarily responsible for ATP production?
A. Ribosome
B. Nucleus
C. Mitochondrion
D. Golgi apparatus
,Answer: C. Mitochondrion
Rationale: Mitochondria generate ATP through aerobic cellular
respiration. ATP serves as the primary energy source for nearly all
cellular functions.
4. Which cellular adaptation is characterized by an increase in cell
size?
A. Hyperplasia
B. Metaplasia
C. Hypertrophy
D. Dysplasia
Answer: C. Hypertrophy
Rationale: Hypertrophy involves enlargement of existing cells, leading to
increased tissue or organ size. Skeletal muscle enlargement after
exercise and left ventricular hypertrophy from hypertension are common
examples.
5. Hyperplasia refers to:
, A. Cell death
B. Increase in cell number
C. Decrease in cell size
D. Cellular degeneration
Answer: B. Increase in cell number
Rationale: Hyperplasia results from increased cell division, increasing
the total number of cells. It may be physiological, such as breast tissue
growth during pregnancy, or pathological, such as endometrial
hyperplasia.
6. Which adaptation is most likely to occur when skeletal muscles are
immobilized in a cast?
A. Hyperplasia
B. Hypertrophy
C. Atrophy
D. Dysplasia
Answer: C. Atrophy
Rationale: Atrophy is a decrease in cell size resulting from reduced
workload, loss of innervation, poor nutrition, aging, or decreased blood
supply. Immobilization commonly causes muscle atrophy.
