Questions & Verified Answers
1. What is the primary function of enzymes in biological systems?
A. To store genetic information
B. To act as structural components of the cell wall
C. To speed up chemical reactions by lowering activation energy
D. To provide a source of energy for the cell
Answer: C
Rationale: Enzymes are biological catalysts that increase the rate of chemical reactions by decreasing the
amount of energy needed to start the reaction. This is an important clinical concept because selecting the
correct answer (C) requires understanding both the pathophysiology and the practical nursing implications.
Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide accurate
patient education.
2. Which of the following molecules is considered the ‘energy currency’ of the cell?
A. DNA
B. RNA
C. Glucose
D. ATP
Answer: D
Rationale: ATP (Adenosine Triphosphate) is the primary energy carrier in all living organisms, capturing
chemical energy obtained from the breakdown of food molecules. Applying this knowledge in clinical settings
supports safe, evidence-based practice and improves patient outcomes. This is an important clinical concept
because selecting the correct answer (D) requires understanding both the pathophysiology and the practical
nursing implications.
3. In which stage of the cell cycle does DNA replication occur?
A. G1 phase
B. S phase
C. G2 phase
D. M phase
Answer: B
Rationale: The S phase (Synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring
between G1 and G2 phases. This is an important clinical concept because selecting the correct answer (B)
requires understanding both the pathophysiology and the practical nursing implications. Recognizing this
principle allows the nurse to prioritize care, anticipate complications, and provide accurate patient education.

4. Which organelle is responsible for cellular respiration and energy production in eukaryotic
cells?
A. Chloroplast
B. Ribosome
C. Mitochondria
D. Lysosome
Answer: C
Rationale: Mitochondria are known as the powerhouses of the cell because they generate most of the cell’s
supply of ATP through cellular respiration. Applying this knowledge in clinical settings supports safe,
evidence-based practice and improves patient outcomes. This is an important clinical concept because
selecting the correct answer (C) requires understanding both the pathophysiology and the practical nursing
implications.
5. What is the correct sequence of the stages of mitosis?
A. Prophase, Anaphase, Metaphase, Telophase
B. Metaphase, Prophase, Anaphase, Telophase
C. Anaphase, Prophase, Metaphase, Telophase
D. Prophase, Metaphase, Anaphase, Telophase
Answer: D
Rationale: The correct order of mitosis is PMAT: Prophase (condensation), Metaphase (alignment), Anaphase
(separation), and Telophase (de-condensation). This is an important clinical concept because selecting the
correct answer (D) requires understanding both the pathophysiology and the practical nursing implications.
Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide accurate
patient education.
6. A cell placed in a hypertonic solution will likely:
A. Shrink as water leaves the cell
B. Stay the same size
C. Swell and burst
D. Divide into two daughter cells
Answer: A
Rationale: In a hypertonic solution, the concentration of solutes is higher outside the cell than inside, causing
water to move out of the cell by osmosis. This is an important clinical concept because selecting the correct
answer (A) requires understanding both the pathophysiology and the practical nursing implications.
Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide accurate
patient education.
