Quizplus · Accepted Answer

The Westgard multirule that has been broken is the 4S rule, which means four consecutive control values are more than 1 standard deviation from the mean. This rule is sensitive to systematic error, which means there may be a problem with the instrument or reagents causing consistently incorrect results. None of the other answer choices include the correct Westgard multirule broken or the correct type of error.
