Questions & Verified Answers
1. Which of the following is considered the basic unit of life?
A. Atom
B. Cell
C. Organ
D. Tissue
Answer: B
Rationale: The cell is the smallest structural and functional unit of an organism, which is a core tenet of the cell
theory. 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.
2. What organelle is primarily responsible for generating ATP through cellular respiration?
A. Golgi apparatus
B. Mitochondria
C. Ribosome
D. Lysosome
Answer: B
Rationale: Mitochondria are known as the powerhouses of the cell because they produce energy in the form of
ATP. 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. 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 the structure of DNA, Guanine always pairs with Cytosine via
three hydrogen bonds. 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. Which process results in two genetically identical daughter cells?
A. Meiosis
B. Fertilization
C. Mitosis
D. Binary fission in eukaryotes
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.
5. What is the primary function of ribosomes in a cell?
A. Lipid synthesis
B. DNA replication
C. Protein synthesis
D. Cellular waste disposal
Answer: C
Rationale: Ribosomes are the sites in a cell where proteins are synthesized from amino acids based on mRNA
instructions. 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.
6. Which of the following is a polysaccharide used for energy storage in animals?
A. Starch
B. Cellulose
C. Glycogen
D. Chitin
Answer: C
Rationale: Animals store glucose in the form of glycogen, primarily in the liver and muscle tissues. 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.
