• Roles of community health nurses
1. A community health nurse is assigned to assess the overall health needs of
a rural community with limited access to healthcare. During the initial
visits, the nurse observes poor sanitation, overcrowded housing, limited
nutrition, and a high prevalence of respiratory and gastrointestinal
infections. Before implementing any interventions, what should the nurse
do first to ensure effective program planning?
A. Begin providing medications for observed conditions immediately
B. Identify and define the specific health problems affecting the community
C. Distribute educational pamphlets about hygiene to all households
D. Analyze hospital admission records from the past year
Answer: B. Identify and define the specific health problems affecting the community
Explanation: The first step in community health assessment is to identify and clearly define
the health problems. This ensures that interventions are targeted, appropriate, and
evidence-based rather than reactive or generalized. Immediate action without assessment
may waste resources or fail to address root causes.
2. A nurse is developing a community-wide program to prevent the onset of type 2
diabetes among adults. Which type of prevention is the nurse focusing on when
designing educational workshops about healthy eating, physical activity, and weight
, management before any participant has developed diabetes?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Quaternary prevention
Answer: A. Primary prevention
Explanation: Primary prevention aims to reduce the risk of disease before it occurs. In this
scenario, the nurse is targeting modifiable risk factors to prevent diabetes onset.
Secondary prevention focuses on early detection, tertiary prevention addresses
management of established disease, and quaternary prevention prevents unnecessary
interventions.
3. During a community immunization clinic, a parent asks which vaccine protects their
child from measles, mumps, and rubella. The nurse knows the child has received all
other standard vaccines on schedule. Which response is correct?
A. DTaP
B. MMR
C. IPV
D. HepB
Answer: B. MMR
Explanation: The MMR vaccine specifically protects against measles, mumps, and
rubella. DTaP protects against diphtheria, tetanus, and pertussis. IPV protects against polio,
and HepB protects against hepatitis B. Knowledge of vaccine schedules is critical in
community health to prevent outbreaks.
4. A public health nurse is conducting surveillance for influenza within a small city over
the past month. She records only the new cases of influenza that occurred during this
time frame. Which epidemiological measurement is the nurse using?
A. Prevalence
B. Incidence
C. Mortality
D. Morbidity
Answer: B. Incidence
Explanation: Incidence measures the number of new cases of a disease in a defined period.
Prevalence measures all existing cases, mortality counts deaths, and morbidity refers to
disease prevalence or severity. Surveillance of incidence is critical for identifying emerging
outbreaks and planning interventions.
5. In a community with high vaccination coverage, the nurse explains that even
unvaccinated individuals are less likely to become ill because most of the population
is immune. What public health concept is the nurse describing?
A. Individual immunity
, B. Herd immunity
C. Life-long immunity
D. Passive immunity
Answer: B. Herd immunity
Explanation: Herd immunity occurs when a sufficient proportion of the population is
immune, reducing the likelihood of disease spread and protecting those who cannot be
vaccinated. It is a cornerstone of public health immunization programs.
6. After a period of heavy flooding, a community reports a surge in cases of cholera and
other diarrheal diseases. Which factor should the nurse prioritize in planning
interventions to prevent further illness?
A. Reducing dietary fat intake
B. Ensuring safe and clean water sources
C. Promoting daily exercise programs
D. Increasing availability of fast food
Answer: B. Ensuring safe and clean water sources
Explanation: Flooding often contaminates water supplies, making waterborne disease
prevention a priority. Interventions should focus on ensuring safe water, sanitation, and
hygiene practices to prevent outbreaks.
7. According to global health statistics, which condition remains the leading cause of
death worldwide?
A. Cancer
B. Heart disease
C. Stroke
D. Diabetes
Answer: B. Heart disease
Explanation: Cardiovascular disease is the leading cause of mortality worldwide,
highlighting the importance of preventive measures and community health interventions
targeting risk factors like hypertension, obesity, and smoking.
8. During a community education session about type 2 diabetes, a nurse explains the
concept of modifiable risk factors. Which factor is modifiable and can be targeted in
prevention programs?
A. Age
B. Family history
C. Physical inactivity
D. Ethnicity
Answer: C. Physical inactivity
Explanation: Modifiable risk factors such as diet, activity level, and smoking can be
