Question 1
Which of the following actions by Florence Nightingale demonstrates her role as an epidemiologist?
- A. She convinced other women to join her in giving nursing care to all the soldiers.
- B. She demonstrated that a safer environment resulted in decreased mortality rat
- D. She obtained safe water and better food supplies and fought the lice and rats.
Show answer and rationale
Correct answer: B — She demonstrated that a safer environment resulted in decreased mortality rat
The correct answer is B because Florence Nightingale demonstrated her role as an epidemiologist by showing that a safer environment led to decreased mortality rates. She implemented measures such as improving sanitation, ventilation, and hygiene in hospitals during the Crimean War, resulting in a significant reduction in deaths. This exemplifies her understanding of how environmental factors impact public health outcomes. Choice A is incorrect because convincing others to provide nursing care does not directly relate to epidemiology. Choice D is incorrect as addressing water, food supplies, lice, and rats pertains more to public health and sanitation practices rather than epidemiology. Choice C is left blank as it does not provide any relevant information.
