Hyperventilation
Increased blood pressure
Decreased PaCO2
Unconsciousness

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

Correct Answer is A
Explanation
Choice A reason: Oral rehydration therapy is the first-line treatment for dehydration due to diarrhea, as it effectively restores fluid and electrolyte balance.
Choice B reason: While chicken broth may provide some salt, it lacks the necessary electrolytes and glucose needed for effective rehydration.
Choice C reason: A hypertonic IV solution is not typically used for dehydration due to diarrhea, as it can exacerbate fluid shifts and dehydration.
Choice D reason: Keeping a child NPO is not recommended as it can lead to further dehydration and delay recovery.
Correct Answer is C
Explanation
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.
