A nurse is caring for an infant who has coarctation of the aorta. Which of the following should the nurse identify as an expected finding?
Upper extremity hypotension
Weak femoral pulses
Frequent nosebleeds
Increased intracranial pressure
The Correct Answer is B
A. Coarctation of the aorta typically results in hypertension in the upper extremities due to increased pressure proximal to the coarctation.
B. Weak or absent femoral pulses are characteristic findings in coarctation of the aorta due to reduced blood flow to the lower extremities beyond the coarctation. This finding indicates peripheral vascular compromise in the lower limbs.
C. Frequent nosebleeds are not typically associated with coarctation of the aorta.
D. Coarctation of the aorta does not directly affect intracranial pressure.

Correct Answer is A
Explanation
A: Varicella (chickenpox) is contagious until all lesions have crusted over. The crusting of the lesions indicates that the virus is no longer active and transmissible.
B: Although a decrease in fever suggests improvement, it does not signify that the child is no longer contagious. Children with varicella are still contagious until all blisters have crusted over.
C: Antibiotics are not effective against viral infections like varicella. Therefore, this statement is inaccurate as it implies antibiotics are part of the treatment for varicella.
D: Varicella is diagnosed clinically and through symptoms rather than titer results. Titer testing is not a standard criterion for determining when a child can return to school.
Correct Answer is B
Explanation
A. While revising the current policy for catheter care may be necessary, it is not the first step in addressing the increase in infections. Understanding the factors contributing to the infections is crucial before policy revision.
B. Identifying possible precipitating factors related to the infections is the first step in addressing the issue. This involves investigating the circumstances surrounding the infections to determine potential causes and contributing factors.
C. While staff training is important, scheduling training before understanding the root cause of the infections may not effectively address the problem.
D. Meeting with providers to discuss measures to decrease infections may be necessary, but it should occur after identifying the precipitating factors to ensure targeted and effective interventions.
