,SECTION 1: Epidemiology & Disease Prevention
Question 1
A community health nurse is reviewing data on a recent influenza outbreak in a
long-term care facility. To determine the proportion of residents who developed new
influenza infections during the month of January, the nurse should calculate which of
the following?
A. Prevalence rate
B. Incidence rate
C. Attack rate
D. Crude mortality rate
Correct Answer: B
Rationale: The incidence rate measures the number of new cases of a disease that
develop in a defined population at risk during a specified time period. In this scenario,
the nurse needs to identify new influenza infections over one month, which requires an
incidence rate. Prevalence rate (A) measures the total number of existing cases (both
new and old) in a population at a specific point or period in time, making it useful for
measuring disease burden but not new occurrence. Attack rate (C) is a specific type of
incidence rate typically used during outbreak investigations for exposed populations
over a short period, but incidence rate is the broader and more standard epidemiological
measure for this purpose. Crude mortality rate (D) measures deaths from all causes in
the total population and is unrelated to measuring new disease cases.
Question 2
,A community health nurse is implementing a program to reduce the incidence of type 2
diabetes in a high-risk neighborhood. The nurse organizes free nutrition education
classes and walking groups for adults with prediabetes. This intervention is an example
of which level of prevention?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Restorative prevention
Correct Answer: A
Rationale: Primary prevention aims to prevent disease before it occurs by reducing risk
factors and promoting health. Teaching nutrition and exercise to adults with
prediabetes targets risk reduction and prevents progression to type 2 diabetes, fitting
the definition of primary prevention. Secondary prevention (B) involves early detection
and screening, such as conducting glucose screenings for diabetes. Tertiary prevention
(C) focuses on managing existing disease to prevent complications, such as teaching
diabetic foot care or insulin administration. Restorative prevention (D) is not a standard
level of prevention in public health nursing.
Question 3
During a community health fair, a nurse screens 500 attendees and identifies that 65
adults have uncontrolled hypertension. This measurement of existing disease in the
screened population at a single point in time represents:
A. Incidence
B. Prevalence
, C. Morbidity rate
D. Case fatality rate
Correct Answer: B
Rationale: Prevalence measures the proportion of a population that has a particular
disease or condition at a specific point in time (point prevalence) or over a period
(period prevalence). The nurse identified 65 existing cases of uncontrolled hypertension
among 500 attendees at a single health fair, which is a point prevalence measurement.
Incidence (A) measures new cases over time, not existing cases at one point. Morbidity
rate (C) is a general term for disease occurrence in a population but does not
specifically describe the measurement of existing cases at a point in time. Case fatality
rate (D) measures the proportion of individuals with a disease who die from it, which is
not applicable here.
Question 4
A community health nurse is analyzing local health data to prioritize community health
problems. Which criterion is most important when determining which health problem
should be addressed first?
A. The problem affects the largest number of community members or has the greatest
potential impact on the community
B. The problem is the easiest and least expensive to address
C. The problem has received the most media attention in recent months
D. The problem aligns with the nurse's personal clinical interests
Correct Answer: A
