Applied Pathophysiology: A Conceptual Approach, 4th Edition
Complete Test Bank - 180 Practice Questions with Answers and
Rationales
UNIT 1: FOUNDATIONS OF PATHOPHYSIOLOGY
Chapter 1: Introduction to Pathophysiology
1. The nucleus, which is essential for function and survival of the cell:
A) is the site of protein synthesis
B) contains the genetic code
C) transforms cellular energy
D) initiates aerobic metabolism
Answer: B
Rationale: The nucleus contains DNA, the genetic code that directs all
cellular activities including protein synthesis, cell division, and
,metabolism. Ribosomes are the site of protein synthesis, while
mitochondria transform cellular energy and initiate aerobic metabolism
.
2. Although energy is not made in mitochondria, they are known as the
"power plants" of the cell because they:
A) contain RNA for protein synthesis
B) utilize glycolysis for oxidative energy
C) extract energy from organic compounds
D) store calcium bonds for muscle contractions
Answer: C
Rationale: Mitochondria extract energy from organic compounds
through cellular respiration, converting it into ATP, the cell's main
energy currency .
,3. The process responsible for generating and conducting membrane
potentials is:
A) diffusion of current-carrying ions
B) millivoltage of electrical potential
C) polarization of charged particles
D) ion channel neurotransmission
Answer: A
Rationale: Membrane potentials are generated by the diffusion of ions
across the cell membrane, creating electrical gradients essential for
nerve impulse transmission .
4. Connective tissue contains fibroblasts that are responsible for:
A) providing a fibrous framework for capillaries
, B) synthesis of collagen, elastin, and reticular fibers
C) forming tendons and the fascia that covers muscles
D) filling spaces between tissues to keep organs in place
Answer: B
Rationale: Fibroblasts are the most common cells in connective tissue
and synthesize extracellular matrix components including collagen,
elastin, and reticular fibers, providing structural support and elasticity .
5. Although all muscle tissue cells have some similarities, smooth
muscle differs by:
A) having dense bodies attached to actin filaments
B) containing sarcomeres between Z lines and M bands
C) having rapid contractions and abundant cross-striations
