A nurse is assessing a client's pulmonary artery wedge pressure (PAWP). The nurse should recognize that an elevated PAWP indicates which of the following complications?

Rationale: A. Hypotension: Hypotension is typically associated with decreased preload and low PAWP rather than elevated values. An elevated PAWP reflects increased pressure in the left heart, which does not occur with simple hypotension alone. B. Hypovolemia: Hypovolemia leads to decreased circulating blood volume, reducing preload and PAWP. It is typically marked by low filling pressures, not elevated wedge pressures. C. Cardiogenic shock: Although cardiogenic shock can be associated with elevated PAWP due to poor cardiac output and fluid backup, it is not as specific a marker as left ventricular failure, which directly affects PAWP. D. Left ventricular failure: Elevated PAWP reflects increased pressure in the left atrium and pulmonary circulation, which is a hallmark of left-sided heart failure. This elevation occurs because the failing left ventricle cannot efficiently pump blood forward.
