Deck 17: Point-Of-Care Instrumentation

Question 1

One of the problems with performing conventional quality control (QC)testing on a single-use disposable POCT device is that:

A) it is a waste of time and product.
B) qualitative devices will not give appropriate values when tested in this way.
C) it does not assess the competency of each operator.
D) only that single testing unit is monitored.

Answer 1

only that single testing unit is monitored.

Question 2

To assess the presence of (not the concentration of)a specific cardiac marker,such as myoglobin in a blood sample,the best POCT analysis to use would be a(n):

A) immunochromatographic technique that is part of a single-use qualitative cartridge test strip.
B) reflectance spectrophotometric technique that is part of a single-use quantitative cartridge with a reader.
C) electrochemical technique that is part of a panel of tests in a multiple-use quantitative bench top device.
D) single use,colorimetric dipstick that is read visually.

Answer 2

immunochromatographic technique that is part of a single-use qualitative cartridge test strip.

Question 3

One of the most important benefits of connectivity between a POCT device and information systems is:

A) the reduction of time that a laboratorian has to spend transcribing results.
B) the ability of any user to interface with their physician or healthcare provider.
C) the ease of comparing POCT device results with routine laboratory methods.
D) facilitation of the transfer and capture of patient POCT and quality-related data into permanent medical records.

Answer 3

facilitation of the transfer and capture of patient POCT and quality-related data into permanent medical records.

Question 4

The Connectivity Industry Consortium (CIC)developed a:

A) set of management standards for the whole process of delivering a high quality POCT service.
B) standard that requires all personnel associated with the delivery of diagnostic results demonstrate their competence.
C) set of standards that ensures POCT devices meet critical user requirements such as interfacing between POCT devices and information systems.
D) standard for quality control that allows POCT devices to use a docking station to assess the quality of that device's results.

Question 5

An example of in vivo POCT technology would be:

A) optical fluorescence.
B) lateral flow immunoassay.
C) light scattering such as nephelometry.
D) spectrophotometry.

Question 6

To document that an individual has satisfactorily completed training and been found competent in the use of a point-of-care testing (POCT)device,it is important to:

A) use a multiple choice test that is completely objective in nature and record the results.
B) assess a practical demonstration of skill through performance of parallel sample analysis.
C) have the individual present a demonstration seminar and quiz the participants.
D) prepare a computer-assisted learning program that provides testing and recordkeeping.

Question 7

Regarding internal quality control (QC)for a bench top analyzer:

A) it is safe to assume that the manufacturer has performed all necessary QC.
B) at least one QC sample should be run a minimum of once per shift.
C) one QC sample should be analyzed whenever there is a change to the testing system.
D) QC samples can be assessed once a day for frequently used devices.

Question 8

The final step in the documentation of satisfactory training of an individual in the use of a POCT device is:

A) observation of that individual's performance of the entire procedure on three different occasions.
B) submission of a certificate of completion of training to an appropriate accrediting agency.
C) performance by that individual of correlation studies using the POC test and a complex piece of lab equipment.
D) the formal designation of that individual as "POCT-competent."

Question 9

The component of a point-of-care testing (POCT)system that detects the reaction of the analyte with a binding molecule or some other type of recognition element is the:

A) reaction cell.
B) sensor.
C) sample delivery system.
D) user interface.

Question 10

In the design of a POCT device,the component that coordinates all the other systems and ensures that all the required processes for an analysis take place in the correct order is referred to as the:

A) reaction cell.
B) sensor.
C) control subsystem.
D) sample delivery system.
