Total Questions: 50
1. A community health nurse is calculating the attack rate for a foodborne illness outbreak. Which formula
should the nurse use?
A) (Number of new cases / total population) × 100
B) (Number of exposed individuals who develop illness / total number exposed) × 100
C) (Number of deaths / total population) × 1,000
D) (Number of existing cases / total population) × 1,000
E) (Number of new cases / population at risk) × 100,000
Answer: B
Rationale: Attack rate is a special type of incidence rate used for outbreaks. It is calculated as (number of
exposed individuals who develop illness / total number exposed) × 100. It measures the proportion of exposed
individuals who become ill.
2. A nurse is reviewing measures of mortality. Which term refers to the number of deaths from a specific
cause per 100,000 population?
A) Crude mortality rate
B) Cause-specific mortality rate
C) Case fatality rate
D) Infant mortality rate
E) Maternal mortality rate
Answer: B
Rationale: Cause-specific mortality rate is the number of deaths from a specific cause divided by the total
population, multiplied by 100,000. Crude mortality rate includes all causes of death.

the nurse expect to see for a point source outbreak?
A) A gradual rise and fall over several weeks
B) A sharp peak followed by a gradual decline
C) A sustained plateau with no clear peak
D) Multiple peaks over time
E) A steady increase with no decline
Answer: B

fall. Propagated outbreaks have multiple peaks. Common source outbreaks have a gradual rise and plateau.

cardiovascular disease?
A) Screening for high blood pressure
B) Administering aspirin to clients with heart disease
C) Providing education on healthy eating and exercise
