Health Nursing Q&A with Rationale |
Chamberlain University
1. During a mass casualty incident, a nurse identifies a patient with a tension pneumothorax.
Which triage color tag should the nurse assign to this individual?
A. Green
B. Yellow
C. Black
D. Red
Correct Answer: D
Expert Explanation: A tension pneumothorax is a life-threatening condition that requires
immediate medical intervention to ensure survival. Under the START triage system,
individuals with compromised breathing or circulation who have a chance of survival are
tagged as red (immediate). This categorization ensures that resources are directed toward
those with the most urgent need for life-saving care.
2. Which intervention is considered a primary prevention strategy in disaster management?
A. Conducting a community disaster drill
B. Developing a family emergency plan
C. Triaging victims at a crash site
,D. Providing psychological first aid after a flood
Correct Answer: B
Expert Explanation: Primary prevention in disaster management focuses on activities that
prevent the occurrence of a disaster or interfere with the disaster’s potential to cause
harm. Developing a family emergency plan empowers individuals to act before an event
occurs, thereby reducing the likelihood of injury or death. This proactive approach is
fundamental to increasing community resilience and lowering overall vulnerability.
3. A community health nurse is investigating a foodborne illness outbreak. What is the first
step in the epidemiological investigation process?
A. Formulate a hypothesis
B. Implement control measures
C. Establish the existence of an outbreak
D. Evaluate the effectiveness of the response
Correct Answer: C
Expert Explanation: Before any investigation can proceed, the nurse must verify that the
number of observed cases exceeds the expected number for that population. Establishing
the existence of an outbreak ensures that resources are not wasted on normal fluctuations
in disease incidence. This foundational step allows the nurse to define the scope of the
problem before moving on to data collection and hypothesis testing.
,4. Which component of the ‘I PREPARE’ environmental exposure assessment tool refers to
evaluating the home environment?
A. Present Work
B. Residence
C. Past Work
D. Environmental Concerns
Correct Answer: B
Expert Explanation: The ‘R’ in the ‘I PREPARE’ mnemonic stands for Residence, which
prompts the nurse to ask about the age and condition of the patient’s home. This includes
screening for potential hazards such as lead paint, radon, or poor indoor air quality.
Understanding the domestic environment is critical for identifying chronic exposures that
may lead to long-term health complications.
5. A nurse is working with a migrant farmworker community. What is the most significant
barrier to healthcare access for this population?
A. Lack of transportation
B. Cultural beliefs regarding medicine
C. Language differences
D. Frequent mobility and temporary housing
Correct Answer: D
, Expert Explanation: The transitory nature of migrant work makes it extremely difficult to
establish a medical home or maintain continuity of care. Frequent relocation often prevents
patients from finishing treatment cycles or receiving follow-up for chronic conditions.
Community health nurses must address this mobility by utilizing mobile clinics and
standardized health records to bridge gaps in care.
6. When planning for a potential bioterrorism event involving anthrax, which medication
should the nurse ensure is in the stockpile for prophylaxis?
A. Oseltamivir
B. Acyclovir
C. Ribavirin
D. Ciprofloxacin
Correct Answer: D
Expert Explanation: Ciprofloxacin is the preferred antibiotic for the prevention and
treatment of inhalational anthrax according to CDC guidelines. In the event of an
aerosolized release, rapid administration of this medication can prevent the onset of severe
disease in exposed individuals. Ensuring the availability of this specific antibiotic is a core
component of disaster preparedness for high-risk biological agents.
7. Which of the following describes the ‘Response’ phase of the disaster management cycle?
A. Identifying risks and community vulnerabilities
B. Restoring the community to its previous state
