Maryville NURS 611 Patho Exam 1 Practice Test
2026 | Verified Answers | Exam Prep
1. Describe the role of lysosomes in maintaining cellular health.
Lysosomes help maintain cellular health by breaking down waste
materials and recycling cellular components.
Lysosomes store and transmit genetic information.
Lysosomes are responsible for protein synthesis.
Lysosomes primarily produce ATP for energy.
2. Describe the significance of the BRCA1 gene in relation to breast cancer.
The BRCA1 gene is responsible for the majority of breast cancer cases.
The BRCA1 gene is unrelated to breast cancer risk.
The BRCA1 gene is significant because mutations in this gene
increase the risk of developing breast cancer, accounting for about
5% of cases.
The BRCA1 gene only affects ovarian cancer risk.
3. Which of the following is an example of physiologic hypertrophy?
Enlargement of muscles from exercise.
Intestinal cell change in the gastric mucosa from gastritis.
Regeneration of the liver after partial resection for metastatic cancer.
Cardiomegaly from chronic hypertension.
Enlargement of uterine fibroid (leiomyoma) during pregnancy.
,4. What is the typical age range for the onset of Huntington's disease
symptoms?
10 to 20 years old
20 to 30 years old
50 to 70 years old
30 to 50 years old
5. What is a common example of physiologic hypertrophy in the human body?
Increased muscle mass from exercise
Enlargement of the heart due to disease
Swelling of the liver from alcohol consumption
Thickening of the skin from sun exposure
6. Describe the significance of relative risk in epidemiological studies.
Relative risk measures the total number of cases in a population over
time.
Relative risk is used to calculate the average age of onset for diseases.
Relative risk provides a direct cause-and-effect relationship between
exposure and disease.
Relative risk helps determine the strength of the association
between exposure and disease, indicating how much more likely the
disease is to occur in the exposed group compared to the
unexposed group.
7. If a patient is exposed to high levels of ionizing radiation, what cellular
response might you expect to observe in their tissues?
, Decreased inflammation
Increased hypertrophy
Enhanced cellular proliferation
Increased apoptosis
8. What type of genetic inheritance pattern is associated with cystic fibrosis?
Autosomal dominant
X-linked dominant
X-linked recessive
Autosomal recessive
9. If a cell's Golgi apparatus is damaged, what cellular process would be most
directly affected?
DNA replication.
Cell division.
Protein and lipid processing and secretion.
Energy production.
10. The chief function of ribosomes is:
cell signaling.
protein synthesis.
ATP production.
lipid synthesis.
11. To an epidemiologist, "incidence" refers to
, the occurrence of a single precipitating incident
the total number of cases of a health disorder that exist at any given
time
the frequency with which new cases of a disorder occur within a
given population
the proportion of a population currently sick from an illness
12. Describe how the secretion of antidiuretic hormone (ADH) relates to the
sensation of thirst.
Thirst is triggered solely by dehydration, without any relation to ADH.
ADH secretion is independent of plasma osmolality and does not
affect thirst.
ADH secretion increases when plasma osmolality rises, which also
stimulates the thirst center in the brain.
ADH decreases thirst by promoting fluid retention.
13. Which of the following characteristics applies to type 1 diabetes mellitus
(DM)?
Significant hyperglycemia and ketoacidosis result from lack of
insulin.
Insulin resistance (IR) is a significant part of the disease.
Initial response to oral sulfonylureas is usually favorable.
This condition is commonly diagnosed on routine examination or
work-up for other health problems.
14. Describe the role of ATP in cellular metabolism and why it is considered the
energy currency of the cell.
