Questions & Verified Answers
1. Which organelle is known as the powerhouse of the cell because it generates most of the
cell’s supply of ATP?
A. Nucleus
B. Ribosome
C. Mitochondria
D. Lysosome
Answer: C
Rationale: Mitochondria are responsible for cellular respiration and the production of ATP, the cell’s energy
currency. 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.
2. Which process results in two genetically identical daughter cells?
A. Meiosis
B. Fertilization
C. Mitosis
D. Binary Fission
Answer: C
Rationale: Mitosis is the process of cell division that results in two daughter cells each having the same
number and kind of chromosomes as the parent nucleus. 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.
3. What is the primary function of ribosomes in a cell?
A. DNA replication
B. Protein synthesis
C. Lipid synthesis
D. Waste breakdown
Answer: B
Rationale: Ribosomes are the cellular machinery where translation occurs, linking amino acids together to form
proteins. 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.

4. In DNA, which nitrogenous base always pairs with Cytosine?
A. Adenine
B. Thymine
C. Uracil
D. Guanine
Answer: D
Rationale: According to Chargaff’s rules and base pairing, Guanine always pairs with Cytosine in a DNA
molecule. 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.
5. Which stage of the cell cycle involves the replication of DNA?
A. G1 phase
B. M phase
C. G2 phase
D. S phase
Answer: D
Rationale: The S phase (Synthesis phase) is the part of the cell cycle in which DNA is replicated. 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.
6. What is the movement of water across a selectively permeable membrane called?
A. Osmosis
B. Active transport
C. Diffusion
D. Facilitated diffusion
Answer: A
Rationale: Osmosis is the specific term for the diffusion of water molecules through a semi-permeable
membrane. 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.
