Questions & Verified Answers
1. Which of the following is the primary component of the cell membrane’s bilayer structure?
A. Phospholipids
B. Proteins
C. Carbohydrates
D. Nucleic acids
Answer: A
Rationale: Phospholipids have a hydrophilic head and two hydrophobic tails, which spontaneously form a
bilayer in aqueous environments, creating the foundation of the cell membrane. Recognizing this principle
allows the nurse to prioritize care, anticipate complications, and provide accurate patient education.
2. Which organelle is known as the ‘powerhouse of the cell’ for its role in generating ATP?
A. Nucleus
B. Mitochondrion
C. Golgi apparatus
D. Ribosome
Answer: B
Rationale: Mitochondria are the sites of cellular respiration, the process that converts biochemical energy from
nutrients into adenosine triphosphate (ATP). 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.
3. During which phase of the cell cycle is DNA replicated?
A. G1 phase
B. G2 phase
C. S phase
D. M phase
Answer: C
Rationale: The S phase (Synthesis phase) of interphase is when the cell replicates its genetic material to
prepare for division. 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.

4. What is the basic building block of a protein?
A. Monosaccharide
B. Amino acid
C. Nucleotide
D. Fatty acid
Answer: B
Rationale: Proteins are polymers composed of chains of amino acids linked together by peptide bonds. 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.
5. Which process results in two genetically identical daughter cells?
A. Mitosis
B. Meiosis
C. Fertilization
D. Translation
Answer: A
Rationale: Mitosis is a type 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 (A) 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. An organism with two identical alleles for a specific gene is described as:
A. Homozygous
B. Heterozygous
C. Phenotypic
D. Haploid
Answer: A
Rationale: Homozygous refers to having inherited the same alleles (e.g., AA or aa) for a particular gene from
each parent. 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.
