Chapter 12- Phlebotomy
This test result represents a pathophysiologic state at such variance with normal as to be life
threatening unless action is taken by the patient's physician? - correct answer-Critical
Laboratory Value
What act requires healthcare worker to report critical laboratory values to physicians in a
timely manner? - correct answer-Critical Laboratory Improvement Act
Verbal reports should be accompanied by documentation with what information? - correct
answer-1) Patient's name
2) Identification #
3) Name of person receiving report
4) Date
5) Time
6) Information given
7) Name of person issuing the report
What regulations ensure patient's privacy and confidentiality wishes are maintained? -
correct answer-HIPPA
What reports are more reliable than verbal reports? - correct answer-Compuerized reports
Verbal reports should not be used to avoid miscommunication errors unless in what
situations? - correct answer-STAT and critical values
These two agencies state that written laboratory results should be confirmed, dated, and
accompanied by permanent reports that are available in the lab as well as on the patient's
medical record via electronic transmission or hard copy? - correct answer-1) The Joint
Commission
2) The College of American Pathologists (CAP)
CAP suggests healthcare workers consider the following data for laboratory test results: -
correct answer-1) ID of patient, patient location, physician
2) Date/time of specimen collection
3) Description, source of specimen, labeled precautions
4) For paper copies, compactness and ease of shipment/mailing
5) Consistency in format
6) Clear understanding of instructions
7) Logical location in patient's medical record for reference lab reports
8) Sequental order of multiple results on single specimens
9) Listing of reference ranges or normal, abnrmal, critical values
10) Assurance of accuracy of request transcription
11) Administraive and record-keeping value
How can laboratory results be recorded? - correct answer-1) Manual recording
, 2) Laboratory instrument printed reports
3) Electronically generated reports
What are centrifuges used for? - correct answer-To seperate serum and plasma and
enhance productivity for turnaround time
These factors should be considered when deciding on the appropriate centrifuge? - correct
answer-1) Type of blood
2) Rotor
3) Spin time
4) Capacity
5) Noise leel and proximity to other instruments
6) Proper training for centrifuge operators
Preexamiantion Variables Phlebotomists need to consider? - correct answer-1) Patient
variables: ID, age, gender, fasting/no faating, medications, stress/anxiety, patient availability,
diurnal variations, and refusal to cooperate
2) Transportation/handling variables: Correct filling and mixing of specimens, specimen
leakage, tube breakage, and excessive shaking
3) Specimen processing/storage variables: Exposure to heat and light, adequacy of
centrifugatin, sample registration/distribution, delays in processing and contamination of
specimen
4) Specimen Variables: Hemolysis, inadequate volume in the tube, inadequate mixing and
anticoagulation
What are the basic steps for safety handling/transporting specimen samples to the
laboratory? - correct answer-1) Gently inverting the tube immediately after collection
2) Labeling the specimen correctly
3) Placing the specimen in a biohazard bag or proper tray
4) Transport to appropriate lab
5) Special handling procedures
6) Microbiological specimens
7) Specimen transportation to/from remote sites
Specimen Delivery methods: - correct answer-1) Hand Delivery
2) Pneumatic Tube Systems
3) Transportation by automated carrier
Name and explain the three phases of specimen processing? - correct answer-1)
Precentrifugation: After the specimen is collected and prior to centrifugation
2) Centrifugation: While the specimen is in the centrifuge
3) Postcentrifugation: after centrifugation of the specimen but before removal of
serum/plasma
No centrifugation is required for what specimens? - correct answer-Hematology (CBC,
differentials, reticulocyte, and nucleated RBC (NRBC), WBC, hemoglobin, platelet count and
coagulation testing
