Correct Answer is B
Explanation
A. Those with chronic conditions cannot escape in time: While this is a risk for some, it does not explain the overall high casualty rates.
B. Victims have little time to make evacuation preparations: Lack of warning and rapid onset are key reasons for higher casualties during bioterrorism and natural disasters.
C. The early warning systems are not effective: While this may be true in some cases, the main issue is often the limited time to respond, not system failure.
Correct Answer is A
Explanation
A. Qualitative: Interviewing and observing behavior generate descriptive, non-numeric data, which is qualitative in nature.
B. Quantitative: Quantitative data involves numerical information (e.g., statistics or counts), which is not directly described here.
C. Focus groups: This is a method of data collection, not a type of data. The scenario describes interviews, not group discussions.
D. Participant observation: This is also a method of data collection, and while the nurse observes behavior, the question focuses on the type of data- which is qualitative.
