Questions & Verified Answers
1. Which organelle is responsible for synthesizing proteins in the cell?
A. Mitochondria
B. Golgi apparatus
C. Ribosomes
D. Lysosomes
Answer: C
Rationale: Ribosomes are the cellular structures where protein synthesis occurs by translating messenger
RNA. 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. In which phase of the cell cycle does DNA replication occur?
A. G1 phase
B. M phase
C. G2 phase
D. S phase
Answer: D
Rationale: The S phase (Synthesis phase) is when the cell replicates its DNA so that each daughter cell
receives a complete set. 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 (D)
requires understanding both the pathophysiology and the practical nursing implications.
3. What is the primary product of the Calvin cycle in photosynthesis?
A. Oxygen
B. G3P (Sugar)
C. ATP
D. NADPH
Answer: B
Rationale: The Calvin cycle uses carbon dioxide and energy from the light reactions to produce G3P, which is
then used to build glucose. 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 type of transport requires energy to move molecules against their concentration
gradient?
A. Simple diffusion
B. Facilitated diffusion
C. Active transport
D. Osmosis
Answer: C
Rationale: Active transport moves substances from low to high concentration, requiring energy in the form of
ATP. 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 genotype of an individual who is a carrier for a recessive genetic disorder but
does not show symptoms?
A. Homozygous dominant
B. Hemizygous
C. Homozygous recessive
D. Heterozygous
Answer: D
Rationale: A carrier has one dominant allele and one recessive allele (heterozygous), masking the recessive
trait. 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.
6. Which nitrogenous base is found in RNA but not in DNA?
A. Adenine
B. Thymine
C. Guanine
D. Uracil
Answer: D
Rationale: RNA uses uracil instead of thymine, which is found in DNA. 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.
