Final answer:
The correct evaluation statement is "D) Goal not met; white blood cell count elevated, presence of yellow-green discharge from wound." as it reflects the presence of infection indicators like elevated white blood cell count and wound discharge against the expected client outcome.
Step-by-step explanation:
The evaluation of a client's progress in remaining free of infection until discharge involves assessing both the objective data, like vital signs and lab results, and the client's physical condition. In this case scenario, the expected outcome is that the client will remain free of infection by discharge. However, the presence of yellow-green discharge from the client's abdominal wound and an elevated white blood cell count of 12,000 suggests a possible infection. Therefore, goal not met; the signs indicate that the infection has not been resolved.
Given the situation at hand, the most appropriate evaluation statement from the options provided would be "D) Goal not met; white blood cell count elevated, presence of yellow-green discharge from wound." This statement directly relates the clinical findings, which include an elevated white blood cell count and purulent discharge, to the unmet goal of being free of infection.
