Choice A rationale:

This statement is appropriate. Unexplained internal and external bleeding is a hallmark symptom of Ebola virus disease (EVD), and it requires immediate medical attention due to its potentially life-threatening nature.

Choice B rationale:

This statement is incorrect. Bleeding is a characteristic symptom of EVD, and the nurse should not dismiss it as being due to another condition without proper evaluation.

Choice C rationale:

This statement is incorrect. Increased white blood cells would not explain the bleeding and are not associated with this symptom in EVD.

Choice D rationale:

This statement is incorrect. Bleeding from the nose and eyes is significant in the context of EVD and should not be downplayed as insignificant.
