How does quality assessment differ from quality control?
Quality assessment methods are used to guarantee quality patient care. Quality control methods are used to monitor the accuracy of procedures.
How often should the procedure manual be renewed
Yearly
A variable is defined as anything that can be changed or altered variables are divided into what three groups
● preexamination variables: processes that occur before testing of the sample
● examination variables: processes that occur during the testing of the specimen
● postexamination variables: processes that affect the reporting and interpretation of test results
How often are centrifuges calibrated
every three months using a tachometer
What does the lean systems focus on
Elimination of waste to allow facility to do more with less and at the same time increase customer and employee satisfaction
What do the 6 S' s stand for in the lean system
Sort, straighten, scrub, safety, standardized, sustain
Arterial blood collection kits contain what
Preanticoagulated syringes with hypodermic needles containing a safety shield
What is the anticoagulant of choice for a ABGs?
Heparin
What do you use on ABGs when samples cannot be tested within 30 minutes
glass syringes and a container of crushed ice or ice and water
Where is the radial artery located
On the thumb side of the wrist
Where is the brachial artery located
Near the basilic vein in the antecubital area
The artery of choice for an arterial puncture is
The radial artery. The ulnar artery can provide collateral circulation to the hand. It lies close to the surface of the wrist and is easily accessible. It can be easily compressed against the wrist ligament so that pressure can be applied more effectively on the puncture site after removal of the needle and there is less chance of a hematoma.
What does the modified Allen test determine
It determines if the ulnar artery is capable of providing collateral circulation to the hand
What do you clean an arterial puncture site with
povidone-iodine or chlorhexidine
How do you insert a needle in the arterial puncture and at what angle
The finger is placed directly over the area where the needle should enter the artery-- not where the needle enters the skin. The heparinized syringe is held like a dart in the dominant hand and the needle is inserted about 5 to 10 mm below the palpating finger at 30 to 45 degree angle with the bevel up
What color is arterial blood
Bright red
Amount of time you apply pressure to an arterial puncture
3 to 5 minutes
Define Arteriopasm.
Spontaneous usually temporary construction of an artery in response to a sensation such as pain. Radial artery is checked for a pulse BELOW the puncture site, and the nurse is notified if a pulse cannot be located.
Define Vasovagal Reaction
Stimulation of the blood vessels by the vagus nerve resulting in a sudden loss of consciousness
Where is point of care performed
The performance of laboratory tests at the patient's bedside or nearby rather than in a central laboratory
What are the advantages of POCT
faster TAT.
What are the POCT glucose normal values
60 to 115 mg/dL in a fasting blood sugar sample. levels below 60 mg/dL are termed hypoglycemic, and increased levels are termed hyperglycemic.
Urine should be tested within what time of collection
2 hours
What does the physical examination of urine include
Color and clarity of the sample. Abnormal colors and increased turbidity can be indications of pathological conditions
Why should aspirins be avoided a week before doing an occult blood sample
Aspirin can cause gastrointestinal irritation causing light bleeding.
What do immunoassay kits contain?
Complete kit include reaction cassettes or cards, color developer, positive and negative controls, and detailed instructions
Where should urine be stored, if it can't be tested within 2 hours
Refrigerated
What do you do when semen specimens are delivered to the laboratory
Must be collected in a warm sterile container and delivered to the laboratory within 1 hour. phlebotomist should record the time of sample collection and specimen should be kept at 37°C
sweat electrolytes test is used to diagnose what
Sodium and chloride is performed to confirm the diagnosis of cystic fibrosis, a genetic disorder of the mucous secreting glands
How much blood is collected when a person donates blood
A unit of blood consist of 405 to 495 mL
At what temperature are you eligible to donate blood
Temperature of 99.5°F or lower
How is donating blood different from venipuncture
To donate blood you need to begin with a soap or detergent scrub and followed by concentration iodine or chlorhexidine. Needle is then taped to the donor's arm when a vein has been found. donors are encouraged to open and close their fist in in the collection to speed the flow of blood in contrast to routine venipuncture hemoconcentration is acceptable in donor blood
What is the fluid call that is collected from a joint
synovial fluid
When unsure of instructions to give a patient regarding a specimen collection where do you get the information from
Procedure manual
What does accessioning refer to?
Assigning barcodes to specimens before their delivery to the laboratory sections
What is an effective means of documenting improper patient identification
With a procedure known as the Delta check. A delta check is the comparison between a patient's previous test results and current results and identification of the patients using barcode technology
What's the POCT testing for coagulation
The anticoagulant heparin is administered intravenously to patients to prevent the formation of clots after certain surgeries. depending on the manufacturer, POCT instruments for coagulation testing are capable of providing a combination of PT INR, APTT, and ACT results are only PT INR results. the type of instrument chosen depends on the needs of the POCT site.
