Questions & Verified Answers
1. What is the first step of the scientific method?
A. Formulating a hypothesis
B. Conducting an experiment
C. Making an observation
D. Analyzing data
Answer: C
Rationale: The scientific method begins with observing a phenomenon which leads to a question. 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. Which organelle is known as the powerhouse of the cell?
A. Nucleus
B. Ribosome
C. Mitochondria
D. Golgi apparatus
Answer: C
Rationale: Mitochondria are responsible for producing ATP through cellular respiration. 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.
3. In a cell membrane, the phospholipid heads are:
A. Hydrophobic
B. Hydrophilic
C. Non-polar
D. Insoluble
Answer: B
Rationale: Phospholipid heads are polar and attracted to water, making them hydrophilic. 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.

4. Which molecule carries genetic information from DNA to the ribosome?
A. tRNA
B. rRNA
C. mRNA
D. ATP
Answer: C
Rationale: Messenger RNA (mRNA) carries the genetic code from the DNA in the nucleus to the ribosomes for
translation. 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. How many chromosomes are in a human somatic cell?
A. 46
B. 23
C. 48
D. 92
Answer: A
Rationale: Human somatic (body) cells contain 46 chromosomes, which is the diploid number. 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. What is the primary function of enzymes?
A. To speed up chemical reactions
B. To act as structural components
C. To store energy
D. To transport oxygen
Answer: A
Rationale: Enzymes act as biological catalysts, lowering the activation energy of reactions. 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.
