1. A nurse is conducting a mock disaster drill for a local community. Which phase of disaster
management is the nurse implementing?
A. Mitigation
B. Response
C. Recovery
D. Preparedness
Correct Answer: D
Expert Explanation: The preparedness phase includes activities such as training, drills,
and the creation of emergency plans before a disaster occurs. This ensures that the
community is ready to act when an actual event takes place. It differs from mitigation,
which involves reducing the long-term risk of a disaster ever happening.
2. Which of the following is an example of secondary prevention in a community setting?
A. Administering the influenza vaccine to elderly residents.
B. Conducting scoliosis screenings for middle school students.
C. Providing physical therapy to a client recovering from a stroke.
D. Teaching a class on heart-healthy nutrition.
,Correct Answer: B
Expert Explanation: Secondary prevention focuses on early detection and screening to
identify health problems in their earliest stages. Scoliosis screening allows for early
intervention before the condition progresses significantly. Primary prevention involves
immunizations or education to prevent disease, while tertiary prevention focuses on
rehabilitation.
3. A nurse is using the START triage system during a mass casualty event. Which client should
be tagged with a RED tag?
A. A client with a respiratory rate of 34 breaths per minute.
B. A client who is not breathing after opening the airway.
C. A client with a minor abrasion who is walking around the scene.
D. A client with a broken arm and a radial pulse of 80.
Correct Answer: A
Expert Explanation: Under the START triage system, a respiratory rate greater than 30
breaths per minute indicates an immediate (Red tag) priority. This classification signals
that the client requires urgent life-saving intervention. Clients who are walking are tagged
Green, and those not breathing even after airway maneuvers are tagged Black.
4. A community health nurse calculates the number of new cases of syphilis in a city during
the past month. Which epidemiological measure is the nurse calculating?
A. Prevalence rate
, B. Mortality rate
C. Incidence rate
D. Attack rate
Correct Answer: C
Expert Explanation: The incidence rate specifically measures the number of new cases of
a disease in a population over a defined period. This differs from the prevalence rate, which
includes both new and existing cases at a specific point in time. Understanding incidence
helps the nurse track the spread and risk of an acute outbreak within the community.
5. A home health nurse is visiting an older adult client. Which finding indicates a potential
environmental health risk?
A. The use of space heaters near curtains in the living room.
B. A water heater temperature set at 115 degrees Fahrenheit.
C. The presence of grab bars in the bathroom.
D. Nonskid mats placed under all throw rugs.
Correct Answer: A
Expert Explanation: Space heaters placed near flammable materials like curtains present
a significant fire hazard in the home. The nurse must educate the client on maintaining a
clear distance between heat sources and combustible items. While lower water heater
