'Do not fulfill the midnight dose of medication X tonight due to the early morning scheduled procedure, where the nurse could reasonably check off 'Med X not given at midnight as instructed'. Similarly, a decision support proposal that a patient should not be given a standard intake questionnaire (because the patient is cognitively impaired) would be marked as 'complete' or 'rejected' when the clinician preps the CarePlan or order set after reviewing the decision support results.
