QUESTIONS WITH ANSWERS & RATIONALES | ALREADY GRADED A+
Question 1: A community health nurse is conducting a windshield survey. Which of the following is the
primary purpose of this assessment method?
A) To interview community leaders about health concerns
B) To gather observational data about the community's physical environment, housing, and resources
C) To analyze vital statistics data
D) To conduct focus groups with residents
Answer: B) To gather observational data about the community's physical environment, housing, and
resources
Rationale: A windshield survey involves driving through a community to observe and collect data on the
physical environment, housing conditions, infrastructure, resources, and visible population characteristics. It
provides valuable observational data that complements other assessment methods.
Question 2: A nurse is calculating the crude mortality rate for a community. Which formula is correct?
A) (Number of deaths from a specific cause / Total population) × 100,000
B) (Total number of deaths / Total population) × 1,000
C) (Number of infant deaths / Number of live births) × 1,000
D) (Number of deaths under age 5 / Total population) × 1,000

QUESTIONS WITH ANSWERS & RATIONALES | ALREADY GRADED A+
Answer: B) (Total number of deaths / Total population) × 1,000
Rationale: The crude mortality rate is the total number of deaths from all causes in a year divided by the total
population, multiplied by 1,000. It is a general measure of population health. Option A describes cause-
specific mortality; Option C is infant mortality; Option D is under-5 mortality.
Question 3: A nurse is using the "epidemiologic triangle" to analyze a community outbreak of salmonella.
Which factor represents the "agent"?
A) Contaminated food
B) Elderly residents at a nursing home
C) Salmonella bacteria
D) Poor hand hygiene among food handlers
Answer: C) Salmonella bacteria
Rationale: In the epidemiologic triangle, the agent is the cause of the disease. For salmonella, the agent is the
Salmonella bacterium. The environment includes contaminated food and poor hygiene practices; the host is
the susceptible population (elderly residents).
Question 4: A community health nurse is conducting a needs assessment. Which data source provides
primary data?
A) Census data
B) Vital statistics reports

QUESTIONS WITH ANSWERS & RATIONALES | ALREADY GRADED A+
C) Focus groups with community residents
D) Hospital discharge data
Answer: C) Focus groups with community residents
Rationale: Primary data are collected directly by the nurse for the specific assessment purpose. Focus groups,
interviews, surveys, and windshield surveys are primary data sources. Census data, vital statistics, and hospital
discharge data are secondary data (collected by others for other purposes).
Question 5: A nurse is calculating the infant mortality rate for a county. In a given year, there were 2,500 live
births and 20 infant deaths. What is the infant mortality rate?
A) 8 per 1,000 live births
B) 20 per 1,000 live births
C) 2 per 1,000 live births
D) 0.8 per 1,000 live births
Answer: A) 8 per 1,000 live births
Rationale: Infant mortality rate = (Number of infant deaths under 1 year / Number of live births) × 1,000. (20
/ 2,500) × 1,000 = 8 per 1,000 live births. This is a key indicator of community health status.

Question 6: A nurse is assessing a community's "social determinants of health." Which of the following is a
social determinant?
A) Genetic predisposition to heart disease
B) Access to quality education
C) Blood type
D) Allergic reactions
Answer: B) Access to quality education
Rationale: Social determinants of health are conditions in which people are born, grow, live, work, and age.
They include education, economic stability, housing, social context, and healthcare access. Genetic factors and
biological characteristics are not social determinants.
Question 7: A community health nurse is conducting a community assessment using the "functional health
patterns" framework. Which question addresses the "nutritional-metabolic" pattern?
A) "How does the community perceive its health?"
B) "What are the community's sleep patterns?"
C) "What is the availability of fresh, affordable food in the community?"
D) "How does the community cope with stress?"
