Answer to Question 1

a

Answer to Question 2

C
Epoprostenol is administered only by intravenous (IV) infusion through a central line. This pa-tient is at risk of catheter-related sepsis, of he is showing signs and symptoms.
Sepsis cannot be confirmed with a urinalysis or a WBC count; those would only indicate that an infection is present.
Withdrawal of the medication is not indicated and would not confirm the nurse's suspicions.
