SECTION 1: CELLULAR STRUCTURE & FUNCTION
1. A 45-year-old patient presents with chronic fatigue. Laboratory studies reveal
decreased ATP production. The nurse practitioner understands that ATP is primarily
generated in which cellular organelle through aerobic respiration?
A. Nucleus
B. Mitochondria
C. Ribosomes
D. Golgi apparatus
Correct Answer: B
Rationale: Mitochondria are the powerhouses of the cell, generating ATP through aerobic
respiration.
2. A nursing student is reviewing cell structure. Which statement correctly describes the
function of the nucleus?
A. It synthesizes proteins for cellular function
B. It contains all of the cell's DNA and controls cell activity
C. It generates ATP for cellular energy
D. It breaks down toxins and waste products
Correct Answer: B
Rationale: The nucleus houses DNA and regulates all cellular activities through gene
expression.
3. A patient with liver disease has impaired drug metabolism. The nurse understands that
drug detoxification primarily occurs in which cellular structure?
,A. Rough endoplasmic reticulum
B. Smooth endoplasmic reticulum
C. Lysosomes
D. Peroxisomes
Correct Answer: B
Rationale: Smooth ER synthesizes lipids and contains enzymes for drug detoxification.
4. A 62-year-old patient with chronic obstructive pulmonary disease (COPD) has impaired
ciliary function in the respiratory tract. The nurse recognizes that cilia primarily function to:
A. Generate ATP for cellular energy
B. Move substances along and act as a filter
C. Synthesize proteins for tissue repair
D. Break down foreign bodies in the alveoli
Correct Answer: B
Rationale: Cilia move mucus and debris along respiratory surfaces to maintain airway
clearance.
5. A 28-year-old male patient is diagnosed with infertility. Semen analysis reveals
immotile sperm. The nurse practitioner understands that the structural defect most likely
involves which cellular component?
A. Cilia
B. Flagellum
C. Microvilli
D. Lysosomes
Correct Answer: B
Rationale: Flagellum is the tail structure that enables sperm motility.

understands that this fluid shift is best explained by which transport mechanism?
A. Active transport requiring ATP
B. Diffusion of solutes from high to low concentration
C. Osmosis of water across a semipermeable membrane
D. Facilitated diffusion using carrier molecules
Correct Answer: C
Rationale: Osmosis drives water movement across membranes toward areas of higher
solute concentration.
7. A nurse is caring for a patient with hyponatremia. The sodium-potassium pump is critical
for maintaining electrolyte balance. Which statement best describes this pump's function?
A. It moves sodium into the cell and potassium out of the cell using ATP
B. It moves sodium out of the cell and potassium into the cell using ATP
C. It allows passive diffusion of sodium and potassium across the membrane
D. It exchanges sodium for calcium across the cell membrane
Correct Answer: B
,Rationale: The Na+/K+ pump actively transports 3 Na+ out and 2 K+ in per ATP
hydrolyzed.
8. Which organelle is responsible for protein synthesis and is composed of large and small
subunits?
A. Golgi apparatus
B. Ribosome
C. Lysosome
D. Peroxisome
Correct Answer: B
Rationale: Ribosomes are the sites of protein translation from mRNA.
9. A patient with a genetic disorder has defective lysosomal enzymes. Which cellular
process would be most affected?
A. ATP production
B. Protein synthesis
C. Intracellular digestion and waste removal
D. Cell division
Correct Answer: C
Rationale: Lysosomes contain hydrolytic enzymes for breaking down cellular waste and
debris.
10. The rough endoplasmic reticulum is distinguished from smooth ER by the presence of:
A. Ribosomes on its surface
B. Lipid synthesizing enzymes
C. Detoxification enzymes
D. Carbohydrate chains
Correct Answer: A
Rationale: Rough ER is studded with ribosomes for protein synthesis.
11. Peroxisomes are cellular organelles that primarily function to:
A. Synthesize ATP
B. Break down fatty acids and detoxify harmful substances
C. Package proteins for secretion
D. Store calcium ions
Correct Answer: B
Rationale: Peroxisomes contain enzymes for beta-oxidation and detoxification reactions.
12. A nursing student correctly identifies that the Golgi apparatus is responsible for:
A. Synthesizing ribosomal RNA
B. Modifying, sorting, and packaging proteins
C. Generating cellular energy
D. Breaking down cellular debris
Correct Answer: B
Rationale: Golgi apparatus modifies proteins and lipids and packages them into vesicles.
, 13. Which cellular structure contains the cell's genetic material and controls cellular
reproduction?
A. Mitochondria
B. Nucleus
C. Ribosome
D. Endoplasmic reticulum
Correct Answer: B
Rationale: The nucleus contains chromosomes with DNA that regulates cell division and
function.
14. Microvilli are specialized cellular structures that function to:
A. Aid in cellular movement
B. Increase surface area for absorption
C. Move substances along cell surfaces
D. Provide structural support
Correct Answer: B
Rationale: Microvilli increase absorptive surface area in cells like intestinal epithelium.
