NUR 426 Exam 1: Community Health Nursing Theory &
Application V2 - Arizona College Updated and Latest
Questions and Correct Answers with Rationale
1. A community health nurse is organizing a program to provide influenza vaccinations to elderly residents
at a local community center. Which level of prevention does this activity represent?
A. Quaternary prevention
B. Secondary prevention
C. Tertiary prevention
D. Primary prevention
Ans: D
Explanation: Primary prevention focuses on preventing the initial occurrence of a disease or injury
through interventions like immunizations. These activities are performed before any disease process has
started to keep individuals healthy. Providing vaccinations reduces the susceptibility of the population to
the influenza virus. It is distinct from secondary prevention, which involves screening for early detection
of existing conditions. Effective primary prevention decreases the overall burden on the healthcare
system by lowering incidence rates.
2. A nurse is conducting a skin cancer screening event at a local beach. This action is categorized as which
level of prevention?
A. Primary prevention
B. Health promotion
C. Tertiary prevention
D. Secondary prevention
,Ans: D
Explanation: Secondary prevention aims at early detection and treatment of disease to limit severity and
adverse effects. Screenings are the hallmark of this level as they identify asymptomatic individuals in the
early stages of illness. By finding skin cancer early, treatment can be initiated sooner to improve the
prognosis. This differs from primary prevention, which would focus on sun protection education to
prevent the cancer entirely. Nurses use secondary prevention to reduce the prevalence of complications
within a community.
3. Which intervention should a community health nurse implement as part of tertiary prevention for a
group of clients with chronic heart failure?
A. Conducting a blood pressure screening clinic
B. Providing a low-sodium diet educational workshop
C. Referral to a cardiac rehabilitation program
D. Distributing flyers about the risks of smoking
Ans: C
Explanation: Tertiary prevention occurs after a disease or disability has occurred and focuses on
rehabilitation and preventing further deterioration. Cardiac rehabilitation helps patients manage their
chronic condition and improve their quality of life after a cardiac event. This level of care aims to
minimize the long-term effects of the disease and restore function. It differs from secondary prevention,
which would involve the initial diagnosis through screening. Community health nurses play a vital role in
ensuring patients have access to these long-term recovery resources.
4. In the epidemiological triangle, which of the following best describes the ‘agent’?
A. A human or animal that harbors the disease
, B. The external factors that allow for disease transmission
C. The factor that must be present for a disease to occur
D. The social and physical surroundings of the individual
Ans: C
Explanation: The agent in the epidemiological triangle is the physical, infectious, or chemical factor that
causes the disease. Examples include bacteria, viruses, toxins, or physical trauma that directly impacts
the host. Understanding the agent is crucial for determining how to disrupt the cycle of transmission.
This component interacts with the host and the environment to determine the distribution of health
states. Identifying the specific agent allows community health nurses to implement targeted prevention
and control measures.
5. A nurse is calculating the number of new cases of COVID-19 in a city during the month of July. This
measurement is known as the:
A. Prevalence rate
B. Mortality rate
C. Incidence rate
D. Attack rate
Ans: C
Explanation: The incidence rate measures the number of new cases of a specific disease occurring in a
population over a specific period. It is used to track the spread of acute conditions and assess the risk of
contracting the disease. This measurement is vital for evaluating the effectiveness of primary prevention
programs. Prevalence, in contrast, includes both new and existing cases at a single point in time.
