Final answer:
The appropriate patient outcome for a patient in shock with decreased cardiac output related to relative hypovolemia is urine output of 0.5 ml/kg/hr. Monitoring urine output is a valuable measure to assess renal perfusion and determine the effectiveness of fluid replacement therapy.
Step-by-step explanation:
A patient outcome that is appropriate for a patient in shock with a nursing diagnosis of decreased cardiac output related to relative hypovolemia is urine output of 0.5 ml/kg/hr. In shock, the body experiences hypovolemia, meaning a decreased blood volume. This can lead to decreased cardiac output, which is the amount of blood pumped by the heart in a minute. Monitoring urine output is a valuable measure to assess renal perfusion and determine if the fluid replacement therapy is effective.
