23 Jul SHOULD THE PHYSICIAN INTERPRET THIS INCREASE IN THE BUN AS REAL PATHOLOGIC CHANGE IN THE PATIENT?
Using the following information from a Levey-Jennings chart which day must the run be re Show more Question 1 Using the following information from a Levey-Jennings chart which day must the run be rejected? Assume that the means in the table are + 2 standard deviations: a. Day 1 b. Day 2 c. Day3 d. Day 4 e. Day 5 Question2 Serum glucose determinations are done on samples from a control pool each day for 30 days. Quality control statistics are then calculated. The mean is 100 mg/dL and the standard deviation is 4 mg/dL. These statistics are used to label a quality control chart for the mean and +2 SD. Samples from the same control pool are then assayed each day along with patient samples and control results are plotted on the chart. Results for the first 10 days are as follows: see figure below On day 7 the control results are more than two standard deviations from the mean. The first thing you would do is: a. Make new reagents and run the control and patients for that day again b. Rerun the control with the same reagents c. Discipline the technologist who was responsible for the unacceptable work d. Call the company to repair the instrument Question 3 Before the first morning run of patients are placed on a chemistry profiler the operator notices that the control values for creatinine are 1.1 and 5.8 mg/dL respectively for level I and II. The +/- 2SD range for level I is 0.9 1.1 mg/dL and for level II is 5.3 5.5 mg/dL. The operator should: a. Report patient creatinines b. Do not report patient values until the QC problem has been resolved c. Report patient values after recalibrating creatinine d. D.Report patients who have plasma creatinine within the normal range Question4 Serum glucose determinations are done on samples from a control pool each day for 30 days. Quality control statistics are then calculated. The mean is 100 mg/dL and the standard deviation is 4 mg/dL. These statistics are used to label a quality control chart for the mean and +2 SD. Samples from the same control pool are then assayed each day along with patient samples and control results are plotted on the chart. Results for the first 10 days are as follows: see figure below Using 95% confidence limits means that 95% of the control values would fall between: a. 96 and 104 b. 92 and 108 c. 88 and 112 D.Cant tell from the information Question5 A patients blood urea nitrogen (BUN) was 50 mg/dl on Day 1 and the control serum for BUN was within 2 SD of the mean on that day. On Day 2 the same patients BUN was 70 mg/dL; again the control value was acceptable. Should the physician interpret this increase in the BUN as real pathologic change in the patient? (The only control level available for this test has a mean value of 20 mg/dL and a standard deviation of 2 mg/dL.) a. True b. False Show less
