Final answer:
The repeat/reject analysis at a mammography site with 250 patients per week should be performed every week.
Step-by-step explanation:
The patient volume at a mammography site is 250 patients per week. To determine how often the repeat/reject analysis should be performed, we need to consider the volume of patients and the time frame needed for analysis. If we assume that the analysis can be done weekly, we would perform it every week. If we assume that the analysis can be done every 2 weeks, we would perform it every 2 weeks. If we assume that the analysis can be done every 2 months, we would perform it every 2 months. Lastly, if we assume that the analysis can be done every 3 months, we would perform it every 3 months. So, the correct answer is A. week.
