ATI Community Health Proctored Exam V3
| 2026 Q&A with Rationale (ATI
Community Health Proctored Exam 2026)
1. A community health nurse is planning a program to educate local families about lead
poisoning prevention. Which of the following levels of prevention is the nurse implementing?
A. Secondary prevention
B. Primary prevention
C. Tertiary prevention
D. Quaternary prevention
Correct Answer: B
Rationale: Primary prevention focuses on preventing the initial occurrence of a disease or
injury. Education programs regarding lead-safe housing and general nutrition to prevent
lead absorption are proactive measures. This intervention occurs before any exposure or
illness has taken place.
2. A nurse is conducting a windshield survey of a new neighborhood. Which of the following
observations indicates a potential environmental health risk?
A. Abundant green space and walking paths.
B. An older apartment building with peeling paint.
C. A high density of grocery stores and pharmacies.
,D. Well-maintained public transportation stops.
Correct Answer: B
Rationale: Older buildings constructed before 1978 are highly likely to contain lead-based
paint, which can flake and create toxic dust. Peeling paint is a visible indicator of an
environmental hazard that can lead to lead poisoning in children. The other options
describe positive community attributes that promote health rather than detract from it.
3. A public health nurse is reviewing the epidemiological triangle for a recent outbreak of
influenza. Which of the following components represents the ‘agent’?
A. The elderly population in the community.
B. The cold winter weather and low humidity.
C. The influenza virus itself.
D. The crowded local shopping mall.
Correct Answer: C
Rationale: In the epidemiological triangle, the ‘agent’ is the animate or inanimate object
that causes the disease. In this scenario, the influenza virus is the causative agent. The
elderly population represents the host, while the weather and the mall represent the
environment.
4. A home health nurse is visiting a client who has a prescription for oxygen therapy at home.
Which of the following instructions should the nurse include in the teaching?
A. Use petroleum jelly to moisten the nostrils.
, B. Store oxygen tanks in an upright, secured position.
C. Wear synthetic fabrics like nylon while using oxygen.
D. Ensure oxygen tubing is at least 15 feet long for mobility.
Correct Answer: B
Rationale: Oxygen tanks must be stored in an upright position and secured to prevent
them from falling and becoming projectiles. Petroleum jelly is oil-based and highly
flammable, so water-soluble lubricants should be used instead. Synthetic fabrics can
generate static electricity, which is a fire hazard in an oxygen-rich environment.
5. A nurse is assisting with a community screening for tuberculosis (TB). Which of the
following clients should the nurse identify as being at the highest risk for TB?
A. A client who works in a suburban office building.
B. A client who recently immigrated from a country with high TB prevalence.
C. A client who lives alone in a rural community.
D. A client who eats a diet high in processed foods.
Correct Answer: B
Rationale: Individuals who have recently immigrated from countries where TB is endemic
are at a significantly higher risk for infection. Crowded living conditions, such as those
found in shelters or correctional facilities, also increase risk. Diet and working in a
suburban office are not primary risk factors for tuberculosis transmission.
