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.

Darkening of urine could also be a result of rifampin-induced discoloration. It's important to differentiate between this harmless side effect and hematuria, which could indicate a more serious issue.
Correct Answer is A
Explanation
A: Methylphenidate should be taken preferably 30 to 45 minutes before meals to reduce the risk of stomach upset. Furthermore, food interferes with its absorption.
B: Administering methylphenidate at bedtime is incorrect because it is a stimulant and can interfere with sleep.
C: Avoiding foods containing tyramine is not relevant for methylphenidate; it is more commonly a concern with certain antidepressants such as MAO inhibitors.
D: There is no need to avoid excess sodium intake specifically related to methylphenidate usage; this advice does not pertain to the side effects or interactions of the medication.
