and Population Health | Actual Q&A with Rationale
(NRS425 Exam 2) | Grand Canyon University
1. A community health nurse is calculating the rate of new cases of COVID-19 in a specific
county over the last 30 days. Which epidemiological measure is being utilized?
A. Prevalence rate
B. Incidence rate
C. Attack rate
D. Mortality rate
Correct Answer: B
Explanation: Incidence rate refers to the number of new cases of a disease occurring in a
population during a specified period. This measure is crucial for understanding the spread
of acute conditions and evaluating the effectiveness of prevention programs. Prevalence, by
contrast, includes all existing cases at a specific point in time.
2. The nurse is evaluating the social determinants of health (SDOH) that contribute to the
high rates of obesity in a local neighborhood. Which factors are considered SDOH? Select all
that apply.
A. Availability of safe playgrounds and parks
B. Proximity to grocery stores selling fresh produce
,C. Individual genetic predisposition to metabolic syndrome
D. Educational level of the household heads
E. Average household income and job security
F. Presence of sidewalk lighting and public transportation
Correct Answer: A, B, D, E, F
Explanation: Social determinants of health are the conditions in which people are born,
grow, live, work, and age. The Five domains include economic stability, education, social
and community context, health and health care, and the built environment. Genetic
predisposition is a biological factor, not a social determinant, as it is inherited rather than
influenced by the environment.
3. A nurse is organizing a community-wide blood pressure screening event at a local church.
Which level of prevention does this represent?
A. Primary prevention
B. Quaternary prevention
C. Tertiary prevention
D. Secondary prevention
Correct Answer: D
Explanation: Secondary prevention focus on early detection and intervention to stop the
progression of a disease. Screening programs, such as those for blood pressure or
,cholesterol, aim to identify individuals in the early stages of a condition before symptoms
become severe. Primary prevention occurs before the disease is present, while tertiary
prevention focuses on rehabilitation.
4. According to the Epidemiological Triangle, which of the following is considered an ‘agent’
in the context of a foodborne illness outbreak?
A. Contaminated potato salad
B. Salmonella bacteria
C. The local restaurant kitchen
D. The patrons who ate the salad
Correct Answer: B
Explanation: The Epidemiological Triangle consists of the agent, host, and environment.
The agent is the animate or inanimate factor that must be present or lacking for a disease
or condition to develop, such as bacteria, viruses, or chemical toxins. The patrons represent
the host, and the restaurant kitchen represents the environment.
5. A community health nurse is implementing a smoking cessation program for pregnant
women. This is an example of which level of prevention?
A. Secondary prevention
B. Primary prevention
C. Tertiary prevention
, D. Risk reduction
Correct Answer: B
Explanation: Primary prevention aims to prevent the onset of disease or injury before it
occurs. By educating pregnant women on smoking cessation, the nurse is attempting to
prevent complications for both the mother and the fetus. This proactive approach focuses
on health promotion and protection from specific threats.
6. When applying the Health Belief Model (HBM), the nurse understands that a patient’s
decision to get a flu vaccine is primarily influenced by:
A. The patient’s interpersonal relationships and social support
B. The availability of the vaccine at a low cost
C. Perceived susceptibility to the flu and perceived benefits of the vaccine
D. The patient’s previous experience with healthcare providers
Correct Answer: C
Explanation: The Health Belief Model posits that health-related action depends on the
simultaneous occurrence of several factors, most notably perceived susceptibility and
perceived benefits. If a person feels they are at risk and that the action (vaccination) will be
effective, they are more likely to comply. This model emphasizes the individual’s subjective
perception of the threat and the solution.
