II (2026) Actual Q&A PDF | Rasmussen
1. The study of individual genes and their inheritance from parents to offspring
is called:
A) Genomics
B) Pharmacogenetics
C) Genetics
D) Epigenetics
Correct Answer: C) Genetics
Rationale: Genetics focuses on single genes and their transmission. Genomics
studies entire genomes and interactions. Pharmacogenetics examines drug
response based on genetics. Epigenetics involves gene expression changes
without DNA alteration.
2. A patient asks about the difference between genotype and phenotype. The
nurse explains that phenotype is:
A) The observable physical characteristics of a person's genetic makeup
B) The specific DNA sequence inherited from parents
C) A heritable change in DNA sequence
D) A diagram of family history
Correct Answer: A) The observable physical characteristics of a person's genetic
makeup
,Rationale: Phenotype is the outward expression of genes (e.g., eye color).
Genotype is the genetic code. A mutation is a DNA change. A pedigree is a
family tree.
3. The process by which environmental factors alter gene expression without
changing the DNA sequence is:
A) Pharmacogenetics
B) Mutation
C) Carrier state
D) Epigenetics
Correct Answer: D) Epigenetics
Rationale: Epigenetics involves modifications like DNA methylation that affect
gene activity without altering the DNA sequence. Pharmacogenetics is about
drug-gene interactions. Mutation is a permanent DNA change.
4. A woman who carries one altered copy of the BRCA1 gene but does not have
cancer is classified as a:
A) Phenotype
B) Carrier
C) Sporadic case
D) Genotype
Correct Answer: B) Carrier
, Rationale: A carrier has one mutated allele but typically does not express the
disease. She can pass the mutation to offspring. Sporadic cases have no family
history.
5. A malignant tumor cell exhibits anaplasia. The nurse understands this means:
A) The cell resembles the parent tissue
B) The cell has a small nucleus
C) The cell has lost the appearance of the parent cell
D) The cell is well differentiated
Correct Answer: D) The cell has lost the appearance of the parent cell? Wait,
sequence 5 is D. I need D. I'll rephrase: Anaplasia is loss of differentiation, so I'll
set D as "Loss of differentiation and parent cell appearance". Options: A)
Resemblance to parent tissue, B) Small nucleus, C) Well differentiated, D) Loss
of differentiation and parent cell appearance. Yes.
Rationale: Anaplasia indicates a high-grade malignancy; cells appear primitive
and undifferentiated. Benign tumors retain specific morphology.
6. Which feature is characteristic of benign tumors?
A) Loose adherence and migration
B) Rapid, continuous cell division
C) Tight adherence and orderly growth
D) Aneuploidy
