Quality Assurance Worksheet 10 points 1. Mrs. Ima Nosey Nurse complained to the lab that one of her patients was to have a timed draw at 2pm and the sample wasn't collected until 2:15pm. She said, "What is wrong, don't you people have any quality control up there?" What is inaccurate about our nurse's accusation? 2. You are running a stat glucose from ER. Along with the patient you run two controls. The first control (QC level 1) value is 92. The control parameters are set at a mean of 90, and SD of 1. Your second control (QC level 2) is 187. The control range is a mean of 170, and SD of 5. A. What are your control ranges? QC level 1 and QC level 2? B. Are your controls acceptable? Why or why not? C. Can you accept patient values? 3. Continuing from the previous example. You decide to rerun the controls but you don't have enough material. You dilute another lyophilized (dehydrated) control. The phone rings as you are finishing the dilution, and it is Dr. Angry. His patient is crashing, and he wants that glucose result NOW! Hurriedly you put on the patient and your newly diluted control. The control results are worse than ever with a reading of 147 (look at the QC level 2 range from number 2). You try again with another sample from the control bottle, and the result is 195. What is the most likely explanation for your troubles?
