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 C
Explanation
Choice A reason: Medication should not be cool as it can cause discomfort or even reflexive actions like vomiting or vertigo. It should be at room temperature⁷.
Choice B reason: Hyperextending the infant's neck is not necessary and could be uncomfortable or unsafe. The position should be natural and comfortable⁷.
Choice C reason: Pulling the pinna downward and straight back is the correct method for infants to straighten the ear canal for proper administration of otic medication⁷.
Choice D reason: Holding the infant in an upright position is not ideal for otic medication administration. The infant should be lying down or sitting with the affected ear facing up⁷.
Correct Answer is ["B","C","D","E"]
Explanation
Choice A reason: It is the nurse's responsibility to administer medication, not the caregiver's, to ensure proper dosage and method.
Choice B reason: Calculating the safe dosage is essential to avoid underdosing or overdosing, which can be harmful to the toddler's health.
Choice C reason: Offering juice after medication can help wash down the taste and ensure the medication is swallowed properly.
Choice D reason: Identifying the toddler by asking the caregiver ensures that the correct child receives the medication, which is a critical safety step.
Choice E reason: Asking the toddler to pick a toy can provide comfort and distraction, making the administration process smoother and less stressful for the child.
