A phlebotomist collects a patient sample for potassium using a syringe because the patient's veins were too small and fragile to allow collection with evacuated tubes. It was a difficult draw, involving much needle probing and pulling on the syringe handle. Which of the following test results is most likely to be influenced by this collection method?

Six Sigma methodology:

Quality system essentials (QSEs) form the basis of a laboratory's quality management system (QMS) and contain the management information needed for a laboratory to perform quality work. Which of the following items might be studied as part of an examination of a laboratory's facilities and safety?

An effective means of documenting improper patient identification is:

Quality system essentials (QSEs) form the basis of a laboratory's quality management system (QMS) and contain the management information needed for a laboratory to perform quality work. Which of the following items might be studied as part of an examination of a laboratory's purchasing and inventory?

The following are valid reasons for performing Delta checks except:

Quality system essentials (QSEs) form the basis of a laboratory's quality management system (QMS) and contain the management information needed for a laboratory to perform quality work. Which of the following items might be studied as part of an examination of a laboratory's personnel?

Turnaround time (TAT) for a test generally means:

Documentation of the time between the delivery of a requisition to the laboratory and the arrival of the associated specimen in the laboratory can be accomplished by the use of:

A phlebotomist is performing point-of-care (POC) glucose measurements on patients in the outpatient clinic using a glucose meter according to established procedures. He or she notices that one patient's glucose value is very high at 327 mg/dL. Lab policy requires that POC glucoses greater than 200 mg/DL be verified by a glucose performed in the central laboratory on an instrument. However, the phlebotomist forgets this requirement in his or her haste to phone the result to the patient's physician as soon as possible. This action has introduced which type of variable into the test system?

Quality assessment (QA) differs from quality control (QC) because:

One of the later steps in Six Sigma is to improve the process under study. Improvements are based on:

An effective means of increasing the accuracy of patient identification is to:

Preexamination variables occur:

Phlebotomy personnel must review the procedure manual (and document this review) :

A Delta check helps to detect potential errors in patient results by:

In a laboratory test, variables:

One effective means of detecting improper patient identification is the:
