Questions & Verified Answers
1. Which organelle is often referred to as the powerhouse of the cell because it generates ATP?
A. Nucleus
B. Mitochondria
C. Ribosome
D. Lysosome
Answer: B
Rationale: Mitochondria are the primary sites of cellular respiration, converting nutrients into ATP energy. 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.
2. The movement of water across a semi-permeable membrane from an area of low solute
concentration to high solute concentration is known as:
A. Active Transport
B. Osmosis
C. Facilitated Diffusion
D. Endocytosis
Answer: B
Rationale: Osmosis is the specific term for the passive diffusion of water across a membrane. 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 of the following molecules contains the genetic instructions for the development and
function of living organisms?
A. RNA
B. Protein
C. DNA
D. Lipid
Answer: C
Rationale: Deoxyribonucleic acid (DNA) stores the genetic information for all cellular life. 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.

4. What is the main component of the plasma membrane in a eukaryotic cell?
A. Cellulose wall
B. Phospholipid bilayer
C. Chitin layer
D. Glycogen chain
Answer: B
Rationale: The plasma membrane is primarily composed of phospholipids arranged in a double layer.
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. In which phase of the cell cycle does DNA replication occur?
A. S Phase
B. G1 Phase
C. G2 Phase
D. M Phase
Answer: A
Rationale: The S (Synthesis) phase is when the cell replicates its DNA content. 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.
6. Which of the following is a characteristic of prokaryotic cells?
A. Presence of a nucleus
B. Presence of membrane-bound organelles
C. Absence of a nucleus
D. Complex multicellular structure
Answer: C
Rationale: Prokaryotes lack a defined nucleus and membrane-bound organelles. 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.
