A floor nurse is receiving report on a patient being transferred from the intensive care unit (ICU). The ICU nurse reports that the patient's pulmonary artery wedge pressures are high. The floor nurse should expect to note

pulmonary crackles.


• An increase in pulmonary artery wedge pressure indicates an increase in fluid and pressure in the pulmonary circulation, leading to pulmonary edema and crackles. This is indicative of left-sided heart failure.

• Hypervolemia is another cause for high wedge pressures and hypertension would be expected if this were the cause.

• Incorrect: Polyuria is unlikely because heart failure results in a decrease in perfusion and low urine output.

• Incorrect: Acidosis is more likely with heart failure.
