A nurse is caring for a patient suspected of having Ebola virus disease (EVD) Which diagnostic test should the nurse anticipate to confirm the diagnosis?
Blood culture.
Chest X-ray.
Urinalysis.
Enzyme-linked immunosorbent assay (ELISA)
The Correct Answer is D
Choice A rationale:
Blood culture. While blood cultures can detect certain infections, they are not the primary diagnostic test for Ebola virus disease (EVD) EVD is typically confirmed through molecular methods.
Choice B rationale:
Chest X-ray. A chest X-ray may show nonspecific findings but is not a specific diagnostic test for EVD.
Choice C rationale:
Urinalysis. Urinalysis is not a primary diagnostic test for EVD. The virus is primarily detected through blood samples.
Choice D rationale:
Enzyme-linked immunosorbent assay (ELISA) This is correct. ELISA is used to detect antibodies or antigens in the blood. It can be used to confirm the presence of Ebola virus antigens or antibodies, aiding in the diagnosis of EVD.

Correct Answer is ["B","C","D","E"]
Explanation
Choice A rationale:
The statement is incorrect. Ebola virus transmission does not occur through the air. It is primarily spread through direct contact with bodily fluids of infected individuals.
Choice B rationale:
This statement is correct. Handling bushmeat, which is the meat of wild animals, can lead to Ebola virus transmission. Infected animals can carry the virus, and handling their meat without proper precautions can result in transmission.
Choice C rationale:
This statement is correct. Direct contact with infected bat's urine can transmit the virus. Bats can carry the Ebola virus, and their bodily fluids can contain the virus, leading to potential transmission.
Choice D rationale:
This statement is correct. Sexual contact with an infected person can transmit the virus. Ebola virus can be present in semen for a significant period after recovery, posing a risk of sexual transmission.
Choice E rationale:
This statement is correct. Consuming contaminated food can transmit the virus. If the food is contaminated with infected bodily fluids or if an infected animal is consumed, transmission can occur.
Correct Answer is D
Explanation
Choice A rationale:
Blood culture is not the primary diagnostic test for Ebola virus disease (EVD) ELISA is a more specific and sensitive test to detect Ebola virus antigens or antibodies in the blood, confirming the diagnosis.
Choice B rationale:
Chest X-ray is not a diagnostic test for EVD. It is used to evaluate lung conditions but is not specific to EVD diagnosis.
Choice C rationale:
Urinalysis is not a primary diagnostic test for EVD. ELISA is a more appropriate test to confirm the presence of the Ebola virus.
Choice D rationale:
Enzyme-linked immunosorbent assay (ELISA) is the correct choice. It detects the presence of Ebola virus antigens or antibodies, providing definitive confirmation of EVD.
