Questions & Verified Answers
1. Which organelle is primarily responsible for the production of ATP during aerobic
respiration?
A. Mitochondrion
B. Chloroplast
C. Ribosome
D. Lysosome
Answer: A
Rationale: The mitochondrion is known as the powerhouse of the cell because it generates most of the cell’s
supply of adenosine triphosphate (ATP) through cellular respiration. Applying this knowledge in clinical settings
supports safe, evidence-based practice and improves patient outcomes.
2. What is the main component of the cell membrane in eukaryotic cells?
A. Cellulose
B. Peptidoglycan
C. Chitin
D. Phospholipid bilayer
Answer: D
Rationale: The cell membrane is primarily composed of a phospholipid bilayer with embedded proteins,
providing a fluid mosaic structure. Recognizing this principle allows the nurse to prioritize care, anticipate
complications, and provide accurate patient education. Exam questions often test the ability to distinguish this
concept from closely related distractors, making a clear rationale essential for mastery.
3. In which phase of the cell cycle is DNA replicated?
A. S phase
B. G1 phase
C. G2 phase
D. M phase
Answer: A
Rationale: The S phase (Synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring
between G1 and G2 phases. Exam questions often test the ability to distinguish this concept from closely
related distractors, making a clear rationale essential for mastery. Applying this knowledge in clinical settings
supports safe, evidence-based practice and improves patient outcomes.

4. Which of the following is a prokaryotic organism?
A. Fungi
B. Protist
C. Animal
D. Bacteria
Answer: D
Rationale: Bacteria are single-celled organisms that lack a membrane-bound nucleus and other organelles,
classifying them as prokaryotes. 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.
5. What type of bond holds two nitrogenous bases together in a DNA molecule?
A. Ionic bond
B. Covalent bond
C. Peptide bond
D. Hydrogen bond
Answer: D
Rationale: Hydrogen bonds form between complementary nitrogenous bases (A-T and C- G) to hold the two
strands of the DNA double helix together. Recognizing this principle allows the nurse to prioritize care,
anticipate complications, and provide accurate patient education. Exam questions often test the ability to
distinguish this concept from closely related distractors, making a clear rationale essential for mastery.
6. Which process results in two identical daughter cells?
A. Meiosis
B. Fertilization
C. Mitosis
D. Binary fission in eukaryotes
Answer: C
Rationale: Mitosis is the process of nuclear division in eukaryotic cells that occurs when a parent cell divides to
produce two identical daughter cells. 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.
