NSG 3480 Exam 2 V2 | NSG 3480 Community
Health | Actual Q&A with Rationale (NSG3480
Exam 2) | Galen College of Nursing
1. A community health nurse is explaining the epidemiological triad to a group of nursing
students. Which of the following components should the nurse identify as the ‘Agent’ in a
scenario involving influenza?
A. The influenza virus itself
B. An elderly patient with chronic obstructive pulmonary disease
C. A crowded elementary school classroom
D. Low vaccination rates in the community
Correct Answer: A
Explanation: The epidemiological triad consists of the host, the agent, and the
environment. The agent is the physical, infectious, or chemical factor that causes the
disease, which in this case is the virus. The environment includes the external factors that
allow for transmission, such as the classroom, and the host is the living being affected by
the agent.
2. A nurse is conducting a screening for hypertension at a local senior center. Which level of
prevention is this nurse demonstrating?
A. Primary prevention
B. Secondary prevention
,C. Tertiary prevention
D. Quaternary prevention
Correct Answer: B
Explanation: Secondary prevention focuses on early detection and screening of diseases to
limit the impact of the condition. Screening activities like blood pressure checks help
identify individuals in the early stages of hypertension who may not yet show symptoms.
Primary prevention focuses on health promotion and preventing the disease before it
occurs, while tertiary prevention focuses on rehabilitation.
3. A community health nurse is performing a windshield survey. Which of the following data
should the nurse include in the assessment?
A. The ethnicity and age distribution based on census data
B. The availability of grocery stores and public transportation
C. Interviews with local government officials about crime rates
D. Hospital readmission rates for the local population
Correct Answer: B
Explanation: A windshield survey is a systematic observation of a community from a
vehicle to gather objective data through the senses. Observed features include the physical
condition of buildings, accessibility of resources like grocery stores, and the presence of
public transit. Data such as census statistics or official interviews are considered secondary
data or informant interviews rather than direct observation from a windshield survey.
, 4. Which criteria must be met for a patient to be eligible for home health services under
Medicare Part A?
A. The patient must be completely bedridden
B. The patient must require daily visits for a period of one year
C. The patient must not have any family members available to assist with care
D. The patient must be homebound and require skilled nursing care
Correct Answer: D
Explanation: To qualify for Medicare-reimbursed home health, a patient must be under
the care of a physician and meet the definition of ‘homebound,’ meaning leaving the home
is a major effort. Additionally, the care provided must be intermittent, skilled nursing care
or physical/speech therapy. Being bedridden is not a requirement, but the need for
professional, skilled intervention is essential for reimbursement.
5. A nurse is working in a hospice setting. What is the primary focus of hospice care compared
to traditional curative care?
A. Aggressively treating the underlying disease to prolong life
B. Focusing solely on the physical needs of the patient during the final week
C. Providing symptom management and support for the quality of life
D. Administering experimental treatments to reverse terminal illness
Correct Answer: C
