Questions & Verified Answers
1. Which organelle is often referred to as the powerhouse of the cell because it generates ATP?
A. Nucleus
B. Ribosome
C. Mitochondria
D. Golgi apparatus
Answer: C
Rationale: Mitochondria are responsible for cellular respiration, which converts nutrients into ATP, the cell’s
energy currency. 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. Which of the following describes a prokaryotic cell?
A. Lacks a membrane-bound nucleus
B. Contains complex organelles like mitochondria
C. Contains a membrane-bound nucleus
D. Is typically larger than a eukaryotic cell
Answer: A
Rationale: Prokaryotic cells, such as bacteria, 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.
3. What is the primary function of ribosomes in a cell?
A. Lipid synthesis
B. Protein synthesis
C. Energy production
D. DNA replication
Answer: B
Rationale: Ribosomes are the sites where translation occurs, assembling amino acids into proteins based on
mRNA sequences. 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 the cell membrane, the ‘fluid mosaic model’ describes which structure?
A. A solid wall of cellulose
B. A double layer of phospholipids with embedded proteins
C. A single layer of proteins floating in water
D. A rigid layer of cholesterol
Answer: B
Rationale: The fluid mosaic model depicts the membrane as a phospholipid bilayer with proteins that can move
laterally within the layer. 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.
5. Which process results in two genetically identical daughter cells?
A. Meiosis
B. Mitosis
C. Fertilization
D. Binary fission in eukaryotes
Answer: B
Rationale: Mitosis is the process of nuclear division that results in two daughter cells with 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 (B) requires understanding both the pathophysiology and the practical nursing
implications.
6. Which nitrogenous base is found in RNA but not in DNA?
A. Thymine
B. Adenine
C. Uracil
D. Guanine
Answer: C
Rationale: RNA uses uracil instead of thymine, which is found in DNA. 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.
