Exam 5: Performance Improvement in the Microbiology Laboratory

Multiple unlabeled specimen have been sent to the laboratory from multiple in-patient locations. The laboratory manager decides corrective action needs to occur. What should be constructed to evaluate and correct the problem?

The following are provisions of CLIA 88, except:

When is a broken process fixed?

A test is performed on a group of 10 patients. Six patients have a disease, and four are free of the disease. If six patients (all known to have the disease) of this group test positive for the disease, we say that the clinical sensitivity of this test is

When performing tests in the microbiology laboratory, the detection limit of a test refers to the _____ of that test.

Assume that a certain test for group A Streptococcus has reported sensitivity and specificity of 90% and 98%, respectively, and the estimated prevalence for group A Streptococcus infection in acute pharyngitis is 5%. What is the PPV of this test?

All of the following activities are included in a laboratory quality control program, except

Usually, negative test results are more reliable in predicting

All the following are components of TJC recommendations for establishing performance monitors, except

Media that do not need to be retested by the hospital laboratory must still undergo observation for all of the following, except

The morning technician arrives at the microbiology laboratory and goes around checking daily temperatures. This person will check temperatures daily on all of the following equipment, except

Commercial media must have quality control testing performed by the manufacturer. Because of high failure rates, all of the following media must be retested by the hospital laboratory, except

All of the following provide guidelines to ensure the continual correct performance of tests, except

What is benchmarking?

In any susceptibility system, variables that can affect the results include the following: 1. Antibiotic potency 2) Inoculum concentration 3) Bactericidal level 4) pH 5) Anion content

In January 2004, The Joint Commission (TJC) implemented performance measurements for organizational systems that are critical to patient safety, quality of care, treatment, and services. This new initiative is called
