Pathophysiology NR 283 Quiz 1 – Practice Questions &
Verified Answers | Latest Update 2026 | Graded A+
1. This is seen in a biopsy of rapid growing tumors It is cells that are undifferentiated,
have variable cell structures, and miotic figures.
Anaplasia
Atrophy
Hypertrophy
2. What is the definition of incubation in the context of infectious diseases?
Time between exposure to microorganism and onset of signs and symptoms
The duration of illness after symptoms appear
The period during which a microorganism multiplies
The time taken for a vaccine to become effective
3. Describe the significance of understanding incidence in the study of pathological
changes.
Incidence measures the severity of a disease in affected individuals.
Incidence indicates the total healthcare costs associated with a disease.
Incidence helps in assessing the risk of developing a disease and
understanding its spread in a population.
Incidence is irrelevant to understanding disease pathology.
4. In a patient with chronic hypertension, which cellular change is most likely to occur
in the heart muscle, and what is the implication of this change?
, Hypertrophy; it can lead to heart failure due to increased workload on the
heart.
Atrophy; it can lead to decreased cardiac output.
Dysplasia; it can lead to abnormal cell growth and potential malignancy.
Metaplasia; it can result in the heart muscle being replaced by fibrous tissue.
5. Describe how a Punnett square can be used to illustrate the inheritance of a single
trait.
A Punnett square shows the physical traits of an organism based on
environmental influences.
A Punnett square determines the overall health of an organism.
A Punnett square visually represents the possible combinations of alleles
from two parents for a specific trait.
A Punnett square is used to calculate the probability of genetic mutations.
6. New cases or conditions:
Mortality
Morbidity
Incidence
Prevalence
7. What term is used to describe a condition with an unknown cause?
Idiopathic
Hereditary
Acquired
, Congenital
8. If a patient develops a complication after surgery, which term would best describe
this condition?
Anaplastic
Iatrogenic
Metaplastic
Dysplastic
9. What is the purpose of a Punnett square in genetics?
To predict the genotypes of offspring from parental genotypes.
To analyze the effects of environmental factors on genetics.
To classify genetic disorders.
To determine the physical characteristics of an organism.
10. What does the term 'incidence' refer to in the context of disease pathology?
Rate of disease progression
Percentage of population affected by a disease
Number of new cases of a disease
Total number of existing cases of a disease
11. Right kidney is greatly reduced in size when compared to the left. The arrow in the
image is pointing out the decrease in size of the right renal artery in addition to the
decrease in the size of the kidney. Atrophy - decrease in size and function of cell
caused by:
, 12. If a patient is diagnosed with a neoplasm, what further classification might be
necessary to determine the treatment plan?
Blood analysis
Genetic testing
MRI scanning
TNM staging
13. Dysplasia of epithelial cells sometimes results from:
