A nurse is caring for a child who is suspected to have Enterobius vermicularis. Which of the following actions should the nurse take?

Collect a stool specimen for culture.

Initiate IV fluids.

Perform a tape test.

Test the stool for occult blood.

Answer and Explanation

The Correct Answer is C

Choice A reason: Collecting a stool specimen for culture is not the preferred method for diagnosing Enterobius vermicularis, as the pinworm eggs are rarely present in the stool.

Choice B reason: Initiating IV fluids is not a diagnostic measure for Enterobius vermicularis and is not relevant unless the child is dehydrated or requires fluids for another reason.

Choice C reason: The tape test is the standard diagnostic procedure for Enterobius vermicularis. It involves placing clear tape around the anus to collect any eggs that may be present, which are then examined under a microscope.

Choice D reason: Testing the stool for occult blood is not a diagnostic measure for Enterobius vermicularis, as this infection does not typically cause bleeding.

Correct Answer is B

Explanation

Choice A reason: This choice is incorrect because a CD4+ T-cell count of less than 200 cells/µL and the presence of PCP are indicative of AIDS, not the chronic asymptomatic phase of HIV.

Choice B reason: This is the correct choice. A CD4+ T-cell count of less than 200 cells/µL and an opportunistic infection such as PCP meet the CDC criteria for an AIDS diagnosis.

Choice C reason: This choice is incorrect. A CD4+ T-cell count of less than 200 cells/µL is below the normal range and is one of the criteria for an AIDS diagnosis.

Choice D reason: This choice is incorrect because the acute HIV infection phase is characterized by a high viral load and a decrease in CD4+ T-cell count, but not necessarily below 200 cells/µL or the presence of opportunistic infections.

A. Hyperventilation B. Increased blood pressure C. Decreased PaCO2 D. Unconsciousness

Correct Answer is D

Explanation

Choice A reason: Hyperventilation can be a sign of oxygen toxicity as the body attempts to balance oxygen and carbon dioxide levels.

Choice B reason: Increased blood pressure is not typically a direct sign of oxygen toxicity; it may be related to other underlying conditions.

Choice C reason: Decreased PaCO2 can be a result of hyperventilation, which is a compensatory mechanism in response to oxygen toxicity.

Choice D reason: Unconsciousness can be a severe sign of oxygen toxicity, indicating a high level of oxygen in the blood affecting brain function.
