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. Administering vancomycin over a longer infusion time, such as 60 minutes, can help reduce the risk of adverse reactions, such as red man syndrome or nephrotoxicity. Slower infusion rates allow for better tolerance of the medication.
B. Vancomycin should be diluted appropriately before administration to reduce the risk of infusion-related reactions.
C. Lidocaine is not typically used prior to vancomycin administration. The use of lidocaine would be more relevant for local anesthesia, not for systemic medication administration like vancomycin.
D. Trough levels are typically obtained just before the next dose of vancomycin is due, not immediately after the infusion.
Correct Answer is B
Explanation
A. A larger-bore needle (usually 18- to 20-gauge) is recommended for blood transfusions to prevent hemolysis and ensure adequate flow rate.
B. Flushing the tubing with 0.9% sodium chloride ensures that it is primed and free from air or any incompatible solutions before starting the blood transfusion.
C. Vital signs should be checked immediately before, during, and after the transfusion to monitor for adverse reactions.
D. Blood transfusions are typically completed over 2 to 4 hours, depending on the clinical context, to reduce the risk of complications.
