When a specimen exceeds stability limits, the preferred action is recollection because testing an unstable specimen produces unreliable results that could harm patient care.

Question 79: A patient taking warfarin asks how to prepare for a PT/INR blood draw. The phlebotomist should advise:

Fast for 12 hours before the draw to reduce drug interactions
Stop taking warfarin 48 hours before the draw
Take warfarin at the usual scheduled time and come in as directed (Correct answer)
Double the dose the night before for accurate baseline measurement

Correct answer: Take warfarin at the usual scheduled time and come in as directed

Patients on warfarin should continue their prescribed dose on schedule; the PT/INR is used to monitor therapeutic levels and should reflect current dosing.

Question 80: What is the BEST way for a American Society of Phlebotomy Technicians professional to stay current with regulatory changes?

Depend on colleagues to share updates informally
Rely solely on employer notifications
Actively monitor regulatory bodies, attend continuing education, and participate in professional associations (Correct answer)
Check regulations only during certification renewal

Correct answer: Actively monitor regulatory bodies, attend continuing education, and participate in professional associations

Staying current requires a multi-faceted approach: monitoring regulatory agencies directly, attending relevant continuing education programs, and participating in professional associations that disseminate regulatory updates.

Question 81: Which blood type is considered the universal donor for red blood cells?

Type AB positive
Type A positive
Type B negative
Type O negative (Correct answer)

Correct answer: Type O negative

Type O negative is the universal red cell donor because it lacks A, B, and Rh antigens, making it compatible with all blood types in emergencies.

Question 82: A phlebotomist is asked to draw a specimen for a fasting glucose test. The patient says they had coffee with sugar 30 minutes ago. The correct action is to:

Draw the specimen and note it on the requisition
Draw the specimen — coffee doesn't count as food
Reschedule the draw after a sufficient fasting period (Correct answer)
Draw the specimen and discard the first tube

Correct answer: Reschedule the draw after a sufficient fasting period

Sugary coffee breaks the fast and will elevate glucose results; the draw should be rescheduled after the required fasting period.

Question 83: Which factor most commonly causes pre-analytical error related to patient preparation?

Drawing the patient in a supine position
Incorrect needle gauge selection
Using the wrong color tube for the test ordered
Patient not following fasting or medication instructions before the draw (Correct answer)

Correct answer: Patient not following fasting or medication instructions before the draw

Non-compliance with pre-collection instructions (fasting, medication timing, exercise restriction) is the leading pre-analytical variable affecting specimen quality.

Question 84: Standard Precautions apply to which of the following?

Only blood and visibly bloody body fluids
Only patients diagnosed with a communicable disease
Only patients who are immunocompromised
Blood, all body fluids, non-intact skin, and mucous membranes of ALL patients (Correct answer)

Correct answer: Blood, all body fluids, non-intact skin, and mucous membranes of ALL patients

Standard Precautions treat blood, all body fluids (except sweat unless visibly bloody), non-intact skin, and mucous membranes from every patient as potentially infectious.

Question 85: When processing a specimen for plasma, what step differentiates it from serum preparation?

Plasma must be refrigerated before centrifugation
Plasma requires a clot activator tube
Plasma requires twice the centrifugation time
Plasma can be centrifuged immediately without waiting for clot formation (Correct answer)

Correct answer: Plasma can be centrifuged immediately without waiting for clot formation

Plasma is obtained from anticoagulated blood that can be centrifuged immediately, whereas serum requires a 30-minute clotting period before centrifugation.

Question 86: Which blood component is primarily responsible for hemostasis and forming a platelet plug?

Leukocytes
Plasma proteins
Thrombocytes (Correct answer)
Erythrocytes

Correct answer: Thrombocytes

Thrombocytes (platelets) aggregate at the site of vessel injury to form a platelet plug, initiating the hemostasis process.

Question 87: In ASPT practice, what happens when regulations are updated or changed?

Professionals must update their knowledge and practices to meet new requirements (Correct answer)
Changes apply only to new professionals entering the field
Existing professionals are permanently grandfathered in
Previous certifications are automatically revoked

Correct answer: Professionals must update their knowledge and practices to meet new requirements

When regulations change, all professionals must update their knowledge and practices to comply with new requirements. While transition periods may exist, compliance with current regulations is mandatory for all practitioners regardless of when they were certified.

Question 88: What is the approximate normal adult platelet count range?

500,000–800,000 per µL
50,000–100,000 per µL
5,000–20,000 per µL
150,000–400,000 per µL (Correct answer)

Correct answer: 150,000–400,000 per µL

The normal adult platelet count is 150,000–400,000 per µL; counts below this range indicate thrombocytopenia and increased bleeding risk.

Question 89: When a patient has an IV line in the arm, blood should ideally be drawn from:

The same arm, above the IV site
The same arm, below the IV site
The opposite arm (Correct answer)
The IV catheter itself with physician order

Correct answer: The opposite arm

Drawing from the opposite arm avoids IV fluid contamination of the specimen; if unavoidable, draw below the IV with the IV shut off for at least 2 minutes.

Question 90: What is the function of erythrocytes in the blood?

Fight infection
Transport oxygen and carbon dioxide (Correct answer)
Produce antibodies
Promote clotting

Correct answer: Transport oxygen and carbon dioxide

Erythrocytes (red blood cells) contain hemoglobin, which carries oxygen to tissues and carbon dioxide back to the lungs.

Question 91: A specimen arrives at the lab with visible lipemia. Which test result is most likely to be affected?

Potassium
Prothrombin time (PT)
Triglycerides (Correct answer)
Complete blood count (CBC)

Correct answer: Triglycerides

Lipemia indicates elevated triglycerides in the blood, which is directly reflected in triglyceride test results and can interfere with other optical-based assays.

Question 92: When aliquoting a specimen, what is the most critical step to prevent specimen mix-up?

Use color-coded aliquot tubes
Complete one aliquot before starting the next
Label all aliquot tubes before transferring specimen (Correct answer)
Centrifuge all aliquots together

Correct answer: Label all aliquot tubes before transferring specimen

All aliquot tubes must be labeled with patient information before any specimen is transferred to prevent misidentification errors.

Question 93: Which documentation practice BEST demonstrates regulatory compliance for ASPT certified professionals?

Filing documents only when audited
Maintaining organized, dated, and signed records of all activities, training, and incidents (Correct answer)
Keeping informal handwritten notes
Relying on memory for routine procedures

Correct answer: Maintaining organized, dated, and signed records of all activities, training, and incidents

Organized, dated, and signed records demonstrate systematic compliance with regulatory requirements. Proper documentation serves as evidence during audits, protects against liability, and shows a pattern of consistent adherence to standards.

Question 94: What is the correct action when a quality control result falls outside the acceptable range?

Repeat QC once without documentation
Report patient results anyway
Call the physician immediately
Document and investigate the failure before reporting patient results (Correct answer)

Correct answer: Document and investigate the failure before reporting patient results

When QC fails, the phlebotomist or lab tech must document the failure, investigate the cause, and resolve the issue before releasing patient test results.

Question 95: What is a key practice in safety and infection control?

Following protocols and safety guidelines (Correct answer)
Guessing procedures
Skipping patient identifiers
Ignoring documentation steps

Correct answer: Following protocols and safety guidelines

Question 96: What is a key practice in specimen handling and processing?

Following protocols and safety guidelines (Correct answer)
Guessing procedures
Ignoring documentation steps
Skipping patient identifiers

Correct answer: Following protocols and safety guidelines

Question 97: In ASPT practice, what happens when regulations are updated or changed?

Professionals must update their knowledge and practices to meet new requirements (Correct answer)
Changes apply only to new professionals entering the field
Previous certifications are automatically revoked
Existing professionals are permanently grandfathered in

Correct answer: Professionals must update their knowledge and practices to meet new requirements

Question 98: A phlebotomist is asked to collect a fasting specimen from a patient who says they ate a small snack 2 hours ago. What is the best course of action?

Proceed without documentation since 2 hours is sufficient for most tests
Collect the specimen and note 'non-fasting' on the requisition (Correct answer)
Collect the specimen and say nothing so the patient is not inconvenienced
Refuse to draw and reschedule without notifying the ordering provider

Correct answer: Collect the specimen and note 'non-fasting' on the requisition

If a non-fasting specimen must be collected, the phlebotomist should document the patient's actual fasting status on the requisition so the provider can interpret results appropriately.

Question 99: What is a key practice in specimen handling and processing?

Following protocols and safety guidelines (Correct answer)
Ignoring documentation steps
Guessing procedures
Skipping patient identifiers

Correct answer: Following protocols and safety guidelines

Question 100: In American Society of Phlebotomy Technicians, what is the PRIMARY purpose of conducting an initial assessment?

To fulfill administrative paperwork requirements
To generate documentation for billing purposes
To establish a baseline and identify needs for appropriate action (Correct answer)
To demonstrate the assessor's expertise

Correct answer: To establish a baseline and identify needs for appropriate action

The initial assessment establishes a baseline of current conditions and identifies specific needs. This foundational information guides all subsequent decisions, planning, and interventions.
