FOCUSED NURSING OA EXAM / ACTUAL EXAM QUESTIONS
AND 100% VERIFIED ANSWERS WITH RATIONALES
GRADED A+ LATEST
1. A county health department notices that emergency department visits for
uncontrolled hypertension have increased among adults living in three low-income
neighborhoods. The community health nurse proposes a program addressing
transportation barriers, access to primary care, and availability of blood-pressure
screenings.
Which characteristic of the proposed approach demonstrates population-focused
nursing?
A. It focuses on treating hypertension after complications occur.
B. It concentrates on improving health outcomes for a defined population.
C. It replaces primary care services with emergency department treatment.
D. It limits nursing interventions to adults who already have hypertension.
Answer: B
Rationale: Population-focused nursing targets the health of groups or defined
populations and addresses factors that influence health outcomes across the
population rather than concentrating only on treatment of individual disease.
2. During an initial community assessment, a nurse observes numerous abandoned
buildings, a lack of sidewalks, several overflowing garbage containers, two closed
grocery stores, and a heavily used highway adjacent to residential housing.
Which action should the nurse take next?
A. Begin an educational program on healthy eating.
B. Contact the mayor and request immediate neighborhood redevelopment.
C. Document the observations as community-level assessment findings.
D. Develop a screening program for respiratory disease.
,Answer: C
Rationale: A windshield survey is a systematic observation of the community's
physical and social environment. The nurse should collect and document
assessment data before planning or implementing interventions.
3. A community health nurse is distinguishing community-based nursing from
community-oriented nursing while planning services for a rural county.
Which activity is most consistent with community-oriented nursing?
A. Providing wound care to a client in the client's home
B. Managing medications for an older adult with heart failure
C. Conducting a diabetes-prevention initiative for adults in the county
D. Performing a dressing change at an outpatient clinic
Answer: C
Rationale: Community-oriented nursing focuses on prevention, health promotion,
and population-level outcomes. The other activities primarily address the health
needs of individual clients.
4. A public health nurse is planning interventions to reduce cervical cancer in a
community. Which action is an example of secondary prevention?
A. Providing HPV vaccination to adolescents
B. Teaching adolescents about safer sexual practices
C. Arranging screening to identify cervical abnormalities early
D. Coordinating rehabilitation for women treated for advanced cervical cancer
Answer: C
Rationale: Secondary prevention involves screening and early detection of disease
so that treatment can begin before complications or progression occur.
Immunization is primary prevention, while rehabilitation after established disease
is tertiary prevention.
,5. A nurse at a community health fair provides influenza vaccinations to adults
who have not previously received the vaccine.
Which level of prevention is represented?
A. Primary
B. Secondary
C. Tertiary
D. Quaternary
Answer: A
Rationale: Primary prevention acts before a disease or injury occurs.
Immunization reduces the likelihood that susceptible individuals will develop the
targeted infection.
6. A county has 80,000 residents. During one calendar year, 400 residents develop
newly diagnosed tuberculosis. At the beginning of the year, 200 residents were
already living with tuberculosis.
Using the population as the denominator, which measure is most directly
represented by the 400 newly diagnosed cases?
A. Prevalence
B. Incidence
C. Mortality rate
D. Case-fatality rate
Answer: B
Rationale: Incidence measures new cases occurring in a population during a
specified period. Prevalence includes existing cases as well as newly identified
cases.
, 7. A town of 20,000 residents reports 300 people currently living with asthma.
During the same year, 50 new diagnoses of asthma are documented.
Which measure best reflects the total burden of asthma currently affecting the
community?
A. Incidence
B. Prevalence
C. Mortality
D. Attack rate
Answer: B
Rationale: Prevalence describes the total number of existing cases in a population
at a particular point or period and therefore reflects disease burden. Incidence
would include only the 50 new diagnoses.
8. A community has 12,000 adults. Over the course of one year, 120 adults die. Of
these deaths, 30 are attributed to cardiovascular disease.
Which statistic would the nurse use to determine the number of cardiovascular
deaths relative to the entire population?
A. Cardiovascular-specific mortality rate
B. Cardiovascular incidence rate
C. Cardiovascular prevalence rate
D. Cardiovascular attack rate
Answer: A
Rationale: A cause-specific mortality rate measures deaths attributed to a
particular cause within a population during a specified period.
