A nurse is caring for a client who is receiving one unit of packed red blood cells (RBCs) due to intraoperative blood loss.
The client reports chills and back pain, and their blood pressure is 80/64 mm Hg. What should be the nurse’s first action?

Choice C rationale
Hepatic encephalopathy is a condition that can cause confusion or delirium in patients with end-stage liver disease and increasing ascites. It occurs when the liver is unable to remove toxins from the blood, such as ammonia, which can then accumulate in the brain and affect mental function. This condition is common in patients with cirrhosis or end-stage liver disease, and can manifest as confusion, changes in sleep patterns, mood alterations, and, in severe cases, coma.
Choice A rationale
While dementia can cause confusion and changes in mental status, it is typically a progressive condition that develops over time. In the context of a patient with end-stage liver failure and

increasing ascites who is usually lucid, a sudden onset of confusion or delirium is more likely to be due to a condition related to their liver disease, such as hepatic encephalopathy.
Choice B rationale
Schizophrenia is a chronic mental disorder characterized by distortions in thinking, perception, emotions, language, sense of self, and behavior. It is not typically associated with end-stage liver disease or ascites. In the context of a patient with end-stage liver failure and increasing ascites who is usually lucid, a sudden onset of confusion or delirium is more likely to be due to a condition related to their liver disease, such as hepatic encephalopathy.
Choice D rationale
While a urinary tract infection (UTI) can cause confusion, especially in older adults, it would not typically be the primary suspect in a patient with end-stage liver failure and increasing ascites. In such a patient, hepatic encephalopathy is a more likely cause of confusion or delirium.

Choice A rationale
While heart failure can lead to fluid volume imbalances, a BNP level of 600 pg/mL alone does not indicate a risk for fluid volume deficit.
Choice B rationale

Being NPO since midnight for an endoscopy could potentially lead to fluid volume deficit, but it’s not the most likely choice. Typically, patients are adequately hydrated before and after the procedure.
Choice C rationale
A patient with gastroenteritis and a fever is at high risk for fluid volume deficit. Gastroenteritis can cause significant fluid loss through vomiting and diarrhea, and fever increases insensible water loss.
Choice D rationale
While patients with end-stage renal failure can have fluid volume imbalances, they are more likely to experience fluid volume excess, especially if they are due for dialysis.
