1. Which of the following best defines the term "risk" in epidemiology?
A) The likelihood of dying from a specific disease
B) Any stressor that directly causes disease
C) A factor that when present increases the chance of disease
D) The number of existing cases in a population
Answer: C
Rationale: Risk is correctly defined as a factor that when present increases the chance of
disease. Option A is incorrect as it describes mortality risk. Option B is wrong because risk
factors are not stressors themselves but conditions that increase the likelihood of encountering
stressors. Option D describes prevalence, not risk.
2. A nurse researcher is studying factors that increase the likelihood of developing type 2
diabetes. Which of the following would be considered a risk factor rather than a stressor?
A) Being laid off from employment
,B) Having a family history of diabetes
C) Going through a divorce
D) Experiencing a natural disaster
Answer: B
Rationale: Family history is a risk factor—a condition that increases the chance of disease.
Options A, C, and D are stressors (life events that cause stress) rather than risk factors. Risk
factors are not stressors but conditions or situations that increase the likelihood of
encountering a stressor.
3. Which statement accurately distinguishes between risk factors and stressors?
A) Risk factors directly cause disease while stressors indirectly cause disease
B) Risk factors increase the likelihood of encountering a stressor
C) Stressors are conditions that increase the chance of disease
D) Risk factors and stressors are interchangeable terms
Answer: B
Rationale: Risk factors are conditions or situations that increase the likelihood of encountering
a stressor. Option A is incorrect because neither directly causes disease in all cases. Option C
reverses the definitions. Option D is incorrect as these terms are not interchangeable.
,4. A community health nurse identifies that a neighborhood has limited access to fresh fruits
and vegetables. In epidemiological terms, this would be classified as:
A) A stressor
B) A risk factor
C) A measure of prevalence
D) A measure of incidence
Answer: B
Rationale: Limited access to fresh fruits and vegetables is a risk factor—a condition that
increases the chance of disease (e.g., obesity, diabetes). It is not a stressor (an acute life event)
but rather an environmental condition. Options C and D are measures of disease frequency, not
risk factors.
5. Which of the following represents the correct definition of prevalence?
A) The number of new cases of a disease in a population
B) The probability of being diagnosed with a disease during a given period
C) The total number of cases of disease existing in a population
D) The number of deaths from a disease in a population
, Answer: C
Rationale: Prevalence is the total number of cases of disease existing in a population at a given
time. Option A describes incidence. Option B describes incidence probability. Option D
describes mortality.
6. A prevalence rate is calculated by:
A) Dividing new cases by the population at risk
B) Dividing total existing cases by the total population
C) Dividing deaths by the total population
D) Dividing new cases by total existing cases
Answer: B
Rationale: Prevalence rate = total number of existing cases ÷ total population. Option A
describes incidence rate. Option C describes mortality rate. Option D is not a standard
epidemiological measure.
7. A nurse is reviewing health data for a county. If the county has 500 existing cases of
hypertension in a population of 50,000, what is the prevalence rate?
A) 1%
B) 10%
