Question list

A typical laboratory setting will use a ——— microscope.

Compound

This create three-dimensional images of the specimens.

Electron microscope

The most common type of microscope used in a general laboratory setting.

Compound microscope

The magnification for this type of microscope is compounded, or increased by two different sets of lenses.

Compound microscope

Under compound microscope, the energy source is a replaceable bulb that sits in the ——— of the microscope and shines very brightly.

Base

This type of microscope is often used to visualize stained blood smears, urine sediment, and various microbiology.

Compound microscope

The 3 supportive structures of a compound microscope are? (B-A-S)

Base, arm, stage

The three light sources of a compound microscope are called (L-C-I)

Light source, condenser, iris diaphragm

The four magnification of compound microscope are called: (O-E-C-F)

Objective lenses, eyepiece, coarse adjustment knob, fine adjustment knob

Always use ——— hands to carry a microscope.

Two

(True or False) Do not touch the light source or the lenses with your fingers.

True

(True or False) When cleaning the objectives, remember always to clean the 40X lens last.

False

(True or False) When moving from one objective to another during use or cleaning procedures, always use the eyepiece.

False

This type of microscope is designed to allow a slightly different view from each of the eyepieces, providing an image with depth and dimension.

Dissecting/stereo microscope

The light source for this type of microscope is diffused or reflectex onto the image rather than shone directly through it.

Dissecting/stereo microscope

The magnification ability of the dissecting microscope is usually only capable of enlarging specimen by ——— or ——— times its normal size.

40, 100

——— ——— are often used for blood bank procedures when the technologist is examining different cerum and cell combinations to look for ——— of the specimen.

Dissecting microscope, agglutination

These may be used for a variety of other purposes in the clinical laboratory when fine, detailed work needs to be performed with some magnification.

Dissecting microscopes

This allows for much greater magnification of specimens, and also provides a three-dimensional image.

Electron microscope

Under electron microscope, these are utilized to “excite” the specimen, and the resulting interaction with the atoms present in the specimen will produce an image to be recorded or studied.

Electrons

This type of microscope may be used to visualize specimens that are far too small to be seen with a compound microscope.

Electron microscope

This type of microscope is not routinely found in clinical laboratories, as the user requires specialized training to operate it and interpret the images created with examination.

Electron microscope

This is an instrument used to prepare blood for transport or testing.

Centrifuge

Used to force the separation of the cells from the fluid portion of the blood (Plasma).

Centrifuge

Centrifuge creates a powerful “artificial” gravity source, called ——— ———.

Centrifugal force

(True or False) Urine specimens may also be centrifuged.

True

Under the maintenance of centrifuge, the rotations per minute (rpms) must also be checked at least ——— using a ———.

Quarterly, tachometer

(True or False) Many centrifuge models have a brushed drive motor, and these brushes must be changed at intervals recommended by the manufacturer.

True

(True or False) All metal components of the centrifuge should also be checked for cracks at least once a month.

True

(True or False) Electrical cord of the centrifuge should be checked for wear semi-annually.

False

(True or False) All medical centrifuges should have a cover that must be open in place when in operation.

False

(True or False) It is important that the centrifuge is balanced before starting.

True

This is used to maintain a cold temperature of the plasma or serum.

Laboratory refrigeration

The refrigerators or freezers in the clinical laboratory should be monitored ———.

Each day

This is used to obtain accurate, reliable temperature readings.

Laboratory thermometer

These are usually made of a measurement device that has the end designed to register the temperature.

Laboratory thermometers

(True or False) To keep the temperature as stable as possible, the door for the refrigerator or freezer should be opened only long enough to read the thermometer.

True

(True or False) No specimens is to be stored in laboratory refrigerators where foods or drink are kept.

False

OSHA

Occupational safety and health administration

To keep pathogens alive until they can be identified, it is necessary to keep them at this temperature for a few days. This temperature is approximately —° to —° Celsius or —° to —° Fahrenheit. A laboratory ——— is used for this purpose.

25, 27, 95, 99, incubator

In addition to incubator, these may used to heat specimens as part of specific testing procedures.

Water baths

This type of instrument measures the length of time necessary for a blood specimen to form a clot when reagents are added.

Prothrombin time test/protime

(True or False) Prothrombin time test / Protime results are reported in minutes.

False

When the protime test is performed, an ——— ——— ——— (INR) is usually reported in addition to the test result.

International normalized ratio

Common analyzer for hemoglobin testing include the ——— hemoglobin testing.

HemoCue

Instruments used for chemistry testing Bye (Mahaba, di ko alam ilalagay, check nalang sa module) Sagot? Sagot.

Sagot

These are used to move liquid from one place to another.

Pipettes

Generally are wide at the top and have a flat base.

Beakers

These have a narrow opening at the top and a rounded bottom that is much larger than the top.

Flasks

These are the best item to use when viewing items under the microscope.

Glass slides

Small panes of glass or plastic placed on top of liquid specimens on the glass slides before viewing.

Cover slips

Often used when the specimen is viewed in a natural state without any preservative or staining.

Cover slips

This is a slim, round container that is used to measure liquids.

Cylinder

A type of cylinder that is marked with specific units to allow for accurate measurement.

Graduated cylinder
