The nurse is caring for a client receiving IV heparin. Which finding requires immediate action?
Correct Answer: B

Lactated Ringer's solution, D5W, and 0.45% sodium chloride are not recommended for administering packed red blood cells because they can cause hemolysis due to their hypotonic or hypertonic nature.
