Four days after admission for cirrhosis of the liver, the nurse observes the following when...

(A) Albumin, a blood volume expander, increases the circulating blood volume by exerting an osmotic pull on tissue fluids, pulling them into the vascular system. This fluid shift causes an increase in the heart rate and blood pressure. (B) Albumin, a blood volume expander, exerts an osmotic pull on fluids in the interstitial spaces, pulling the fluid back into the circulatory system. This fluid shift causes an increase in the urinary output. (C) Adventitious breath sounds and dyspnea can occur due to circulatory overload if the albumin is infused too rapidly. (D) Chills, fever, itching, and rashes are signs of a hypersensitivity reaction to albumin.
