A nurse is assessing an infant who has coarctation of the aorta. Which of the following findings should the nurse expect? (Select all that apply.)
Clubbing of the fingers
Weak femoral pulses
Cool skin of lower extremities
Low blood pressure
Severe cyanosis
Correct Answer : B,C
Choice A reason: Clubbing of the fingers is not typically associated with coarctation of the aorta; it is more commonly seen in chronic hypoxia conditions.
Choice B reason: Weak femoral pulses are expected in coarctation of the aorta due to the narrowing of the aorta, which can reduce blood flow to the lower extremities.
Choice C reason: Cool skin of the lower extremities can be a result of decreased blood flow due to the narrowed aorta in coarctation.
Choice D reason: High blood pressure is more commonly associated with coarctation of the aorta, especially in the upper body, due to the narrowing of the aorta increasing resistance to blood flow⁷.
Choice E reason: Severe cyanosis can occur in coarctation of the aorta if there is a significant obstruction to blood flow, leading to poor oxygenation.

Correct Answer is ["B","D","E"]
Explanation
Choice A reason: Waiting 30 seconds between puffs allows the medication to settle and ensures the second puff is as effective as the first.
Choice B reason: Shaking the device before use helps to mix the medication properly, ensuring a consistent dose with each inhalation.
Choice C reason: Exhaling quickly after inhalation is not recommended; instead, the patient should hold their breath for a few seconds to allow the medication to reach deep into the lungs.
Choice D reason: Rinsing the mouth and expectorating after administration prevents oral thrush, a common side effect of inhaled corticosteroids.
Choice E reason: Inhaling slowly ensures that the medication is delivered deeply into the lungs for maximum efficacy.
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.
