1. A community health nurse is conducting an environmental health assessment. Which of
the following questions best aligns with the ‘I’ in the I PREPARE mnemonic?
A. ‘What is your current occupation?’
B. ‘Have you ever felt sick after coming in contact with chemicals?’
C. ‘How old is your home?’
D. ‘Do you have any hobbies that involve hazardous materials?’
Correct Answer: B
Explanation: The ‘I’ in the I PREPARE mnemonic stands for Investigate potential
exposures. Asking the patient if they have felt sick after contact with chemicals helps
identify current or past exposure risks. This systematic approach allows the nurse to link
environmental factors directly to clinical symptoms.
2. Which of the following activities are included in the Disaster Preparedness phase for a
community? (Select All That Apply)
A. Conducting a community risk assessment
B. Identifying emergency shelters and evacuation routes
,C. Performing triage during an active flood
D. Participating in disaster drills and exercises
E. Stockpiling emergency supplies and medications
F. Rebuilding damaged infrastructure after a tornado
Correct Answer: A, B, D, E
Explanation: Disaster preparedness involves proactive planning and training before an
event occurs. Identifying shelters, conducting drills, and stockpiling supplies are essential
components of this phase to ensure a rapid response. Triage is part of the response phase,
and rebuilding is part of the recovery phase.
3. During a mass casualty incident, the nurse uses the START triage system. A victim is
breathing at a rate of 28 breaths per minute, has a capillary refill of 4 seconds, and follows
simple commands. What color tag should be assigned?
A. Red
B. Yellow
C. Green
D. Black
Correct Answer: A
Explanation: According to the START triage system, a capillary refill time of over 2
seconds indicates immediate need for care, resulting in a red tag. Although the respirations
, are under 30, the delayed capillary refill takes precedence in prioritizing this patient.
Prompt identification of circulatory compromise is vital for survival in disaster scenarios.
4. The nurse is evaluating the health of a population using the ‘Global Burden of Disease’
(GBD) concept. This metric primarily measures:
A. The total economic cost of health care in a specific country.
B. The number of hospitals available per capita.
C. The rate of infectious disease transmission across international borders.
D. The combination of years of life lost due to premature mortality and years lived with
disability.
Correct Answer: D
Explanation: The Global Burden of Disease measures the gap between current health
status and an ideal situation where everyone lives to old age free of disease. It uses
Disability-Adjusted Life Years (DALYs) to quantify the impact of health problems. This
allows researchers and policymakers to compare the effects of different diseases across
diverse populations.
5. Which of the following are considered social determinants of health that contribute to
health disparities? (Select All That Apply)
A. Access to safe housing
B. Level of education and literacy
C. Individual genetic predispositions
