Questions & Verified Answers
1. Which organelle is primarily responsible for the synthesis of proteins within the cell?
A. Mitochondria
B. Golgi apparatus
C. Lysosomes
D. Ribosomes
Answer: D
Rationale: Ribosomes are the cellular structures where protein synthesis occurs by translating mRNA into
polypeptide chains. 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.
2. In the cell cycle, during which phase is the DNA replicated?
A. G1 phase
B. G2 phase
C. S phase
D. M phase
Answer: C
Rationale: The S phase (Synthesis phase) is the period of the cell cycle during which DNA is replicated,
ensuring each daughter cell receives a full set of chromosomes. 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.
3. Which process results in the production of two genetically identical daughter cells?
A. Mitosis
B. Fertilization
C. Meiosis
D. Binary fission
Answer: A
Rationale: Mitosis is a type of cell division that results in two daughter cells each having the same number and
kind of chromosomes as the parent nucleus. 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 (A) requires understanding both the pathophysiology and the practical nursing
implications.

4. What is the primary energy currency of the cell?
A. Glucose
B. NADH
C. ATP
D. Pyruvate
Answer: C
Rationale: Adenosine triphosphate (ATP) is the main energy carrier used by cells to power various biological
processes. 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. Which of the following is a characteristic of prokaryotic cells?
A. Presence of a nucleus
B. Membrane-bound organelles
C. Complex cytoskeleton
D. A single circular chromosome
Answer: D
Rationale: Prokaryotic cells, such as bacteria, lack a nucleus and membrane-bound organelles, typically
possessing a single circular chromosome. 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. Which base always pairs with Cytosine in a DNA molecule?
A. Adenine
B. Guanine
C. Uracil
D. Thymine
Answer: B
Rationale: According to Chargaff’s rules for base pairing in DNA, Cytosine always pairs with Guanine via three
hydrogen bonds. 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.
