307 Study Guide Flashcards
A surgical probe is
A slender rod with a blunt, bulb shaped tip that is used to explore wounds or body cavities and to locate or clear blockages
The P-R interval is the
Time it takes electrical impulses to travel from the SA node to the AV node
A peak flow rate in the green zone indicates
Good control of asthma with peak flow rates of 80 to 100 % of the person’s highest peak flow rate
The organism in the figure is a deer tick
which is considered a parasitic insect
The parasitic insect in the figure are mites
Which can burrow under the skin and cause scabies infestations
A KOH mount is a type of
Wet mouth in which potassium hydroxide is added to dissolve the keratin in skin, nails, hair, or vagina to allow visualization of any fungus
An artifact is a foreign object that is
Visible through a microscope, but is unrelated to the specimens
During the proliferation phase of healing
New tissues form
A culture is a sample of a
Specimen that is placed in or on a substance that contains the nutrients microorganisms need to grow
V6 shows a flat line. Gillian is still talking, therefore she is not in cardiac arrest. At this point you should
check the electrode and wire for V6 to see if it has become loose or disconnected
If a lead does not appear on an ECG tracing, or you see a flat line, it is usually because
A loose or disconnected wire
A biopsy specimen is a
Small amount of tissue removed from the body for examination under a microscope
Encourage the patient to
Ask questions about the process and clear up any misunderstandings the patient may have. Assure the patient that no electricity passes through the body
An enormous mark or defect in an ECG strip is called
An artifact
Diplococci are
Pairs of cocci
It is always a good idea to preform electrocardiography in a room away from
All other electrical equipment- Air conditioners, fans, and laboratory and diagnostic equipment
Retractors are
Surgical instruments used to hold back the sides of a wound or incision to provide greater access to and a better view of the surgical site
A spirometer measures
The air taken in by and expelled by the lungs
In atrial fibrillation
Impulses from areas of the atria other than the SA appear in the ECG tracing, making the P waves
A centrifuge is a device
For spinning a specimen at high speed until it separates into its component parts
Wearing examination gloves, suspended the specimen in a drop of 10%
Potassium hydroxide, apply a coverslip and allow the slide to sit at room temperature for 30 minutes before presenting it to the physician for examination
The purpose of the side clips is to
Hold the slide that contains the specimen in place on the stage
The SA node is the
Primary pacemaker of the heart
Depolarization is the
Electrical impulse that starts a chain reaction resulting in contraction or the heart
A peak flow rate in the yellow zone indicates that
Large airways are beginning to narrow
Pulmonary function tests measure and evaluate
A patients lung capacity and volume. They may be preformed as a part of a general examination or when a person suffers from shortness of breath
The Sinoatrial (SA) node initioate the
Heartbeat
The organisms in the figure are mold, which is a type of
Fungi
As the stylus becomes warmer, it produces a
Thicker and heavier line
Tests of high complexity include
tests in clinical cytogenics, histopathology, histocompability, and cytology, as well as any test not yet categorized by the CMS
Scabies is caused by the parasite
Sarcoptes scabiei
A peak flow rate in the red zone is less than
50% of the persons highest or best personal reading. This is considered a medical emergency
Body lotions and creams can cause a
Wandering baseline. Re prep Mrs. Thomas skin using alcohol to remove the residue from a lotion and try the ECG again
Control samples and standards are bothe specimens taken from a patient and have known values. Control samples are used
Before each patients samples is processed. When you calibrate medical equipment, you run thr standard with the known value
In Laser surgery, a laser emits
An intense beam of light that is used to cut away tissue
A photometer which measures light intensity is a basic
Electronic component of many pieced of analytic laboratory equipment
Place the v4 electrode in the
5th intercostal space, where it intersects an imaginary line drawn straight down thr midclavicluar line
Premature ventriclar contractions occur
Early in the cycle, before the regular heartbeat and are followed by a pause before the next cycle
A mechanical or manual pipette is used to
Measure small amounts of liquid
Epinephrine constricts the
Blood vessels, which reduces bleeding and prolongs the action of the local anesthetic
The Q-T interval represents the
Time it takes for the ventricles to contract and then repolarize
Rheumatic fever is an
Inflammation of the heart tissue that occurs most frequently in school aged children
Eukaryotic cells are
Complex cells that contain a nucleus and specialized organelles in the cytoplasm
Microscope parts
A flat line can be the result of
A loose or detached wire
Tell the patient that the initial cold sensation will be followed by a
Burning sensation when preforming cyrosurgery
The focus of quality control program is to
Ensure accuracy in test results through careful monitoring of test procedures
The coverslip and slide
Support and position the specimen. They also prevent contamination of the microscope by the specimen
If you work in a facility that uses latex gloves
Clean areas and equipment containing latex contamining dust frequently will help eliminate allergies
