NOTE: The midterm exam will pull:
40 questions from Chapters 1, 2, and 3
combined, 16 questions from Ch. 4, 19
questions from Ch. 5, & 25 questions from Ch. 6.
A nursing student is studying the organization of the human body. Which of the following
represents the correct order of structural organization from simplest to most complex?
a. Organism → Organ system → Cell → Tissue → Organ
b. Cell → Tissue → Organ → Organ system → Organism
c. Organ system → Organ → Tissue → Cell → Organism
d. Tissue → Organ → Cell → Organ system → Organism
✔️ Correct Answer: B
Page
,Rationale: The correct hierarchy of structural organization is: Cell → Tissue → Organ → Organ
system → Organism. Cells are the basic unit of life; tissues are groups of similar cells performing a
common function; organs are composed of different tissues working together; organ systems
consist of multiple organs; and the organism represents the entire living being. Options A, C, and
D present incorrect sequences.
A biology student is learning about homeostatic mechanisms. Which type of feedback mechanism
is most common in maintaining homeostasis?
a. Positive feedback
b. Negative feedback
c. Neutral feedback
d. Reverse feedback
✔️ Correct Answer: B
Rationale: Negative feedback mechanisms are the most common homeostatic control
mechanisms. They reduce or reverse the effect of a stimulus to maintain balance. Examples
include temperature regulation and blood glucose control. Positive feedback (Option A) amplifies
changes and is less common (e.g., childbirth). Options C and D are not recognized feedback
mechanisms.
A student is studying cellular organelles. What is the primary function of mitochondria?
a. Protein synthesis
b. Detoxification
c. ATP production
d. DNA replication
✔️ Correct Answer: C
Rationale: Mitochondria are known as the "powerhouses" of the cell because they produce ATP
(adenosine triphosphate) through cellular respiration. Option A (protein synthesis) occurs at
ribosomes. Option B (detoxification) occurs in the smooth endoplasmic reticulum and
peroxisomes. Option D (DNA replication) occurs in the nucleus.
A nursing student is identifying tissue types. Which type of tissue lines body surfaces and cavities?
Page
, a. Muscular
b. Epithelial
c. Connective
d. Nervous
✔️ Correct Answer: B
Rationale: Epithelial tissue covers body surfaces, lines internal cavities and organs, and forms
glands. Options A, C, and D are the other three primary tissue types: muscular tissue enables
movement; connective tissue supports and binds; nervous tissue transmits impulses.
A student is studying the endoplasmic reticulum. What is the function of the rough endoplasmic
reticulum (RER)?
a. Lipid synthesis
b. DNA replication
c. Protein synthesis
d. Detoxification
✔️ Correct Answer: C
Rationale: The rough endoplasmic reticulum (RER) has ribosomes attached to its surface and is
involved in protein synthesis. Option A (lipid synthesis) occurs in the smooth ER. Option B (DNA
replication) occurs in the nucleus. Option D (detoxification) occurs in the smooth ER.
A nursing student is studying connective tissues. Which connective tissue connects bone to bone?
a. Tendon
b. Ligament
c. Cartilage
d. Fascia
✔️ Correct Answer: B
Rationale: Ligaments connect bone to bone at joints. Option A (tendons) connect muscle to
bone. Option C (cartilage) provides cushioning between bones. Option D (fascia) surrounds
muscles and other structures.
