Try the questions in the test above first, then open each one here to see the correct answer and why every other option is wrong.
01A phlebotomist cannot find a suitable vein in either antecubital fossa. Which site is the usual next option for venipuncture?
Practice question Unit: Human Anatomy and Physiology
AVeins on the palmar side of the wrist
The palmar wrist has nearby nerves and tendons and is not the usual routine alternative.
BVeins on the back of the hand ✓ Correct answer
Dorsal hand veins are a usual alternative when antecubital veins are unsuitable.
CLeg or foot veins without a physician order
Lower-limb venipuncture has additional risks and requires authorisation under local policy.
DThe femoral vein in the groin
Femoral access is a deep invasive procedure, not routine peripheral phlebotomy.

02In which vessels does exchange of gases and nutrients with tissues take place?
Practice question Unit: Human Anatomy and Physiology
AArterioles
Arterioles regulate blood flow entering capillary networks.
BLarge veins
Large veins return blood to the heart rather than forming the principal exchange network.
CCapillaries ✓ Correct answer
Thin capillary walls permit exchange of gases and nutrients with surrounding tissues.
DElastic arteries
Elastic arteries conduct and buffer high-pressure blood flow rather than provide the exchange surface.

03Breaking the chain of infection at the 'portal of entry' is best achieved by which action?
Practice question Unit: Microbiology and Infection Control
ACovering a cough with a tissue
Covering a cough targets the portal of exit from an infected person.
BTreating the infected patient with antibiotics
Antimicrobial treatment targets the organism and its infected reservoir.
CVaccinating staff against hepatitis B
Vaccination reduces host susceptibility rather than directly preparing the puncture entry site.
DAseptic skin preparation before the puncture ✓ Correct answer
Skin antisepsis reduces organisms at the point where the needle breaches the protective skin barrier.

04An inpatient has no identification wristband. What should the phlebotomist do?
Practice question Unit: Clinical Skills Phlebotomy: Adult/Geriatric
ADraw and label from the requisition
A requisition alone does not establish that the person in front of you is the correct inpatient.
BNot draw until nursing staff attach a wristband ✓ Correct answer
Follow the inpatient identification process and have an identification band attached before drawing.
CAsk the patient's visitor to confirm
A visitor statement does not replace the required patient-identification procedure.
DTape a band to the bed rail
A band on the bed identifies a location, not securely the patient.

05How should a fingerstick puncture be oriented relative to the fingerprint lines?
Practice question Unit: Clinical Skills Phlebotomy: Paediatrics
AOn the side of the nail, close to the cuticle
The nail-side region is not the recommended finger-pad puncture area.
BOn the tip of the finger
The extreme fingertip is more sensitive and is not the preferred puncture site.
CParallel to the lines
A parallel cut allows blood to run along the fingerprint grooves.
DPerpendicular (across) the lines ✓ Correct answer
A cut across fingerprint ridges helps blood form a drop instead of running along a groove.

06Before inoculating a blood culture bottle, what should be done to the bottle top?
Practice question Unit: Special Collections
ANothing; the cap is sterile
The septum under a removable protective cap should not be assumed sterile.
BApply povidone-iodine and leave it wet
Leaving antiseptic wet does not follow the required preparation and drying process.
CDisinfect it with alcohol and let it dry ✓ Correct answer
Disinfect the septum as recommended by the manufacturer, commonly with alcohol, and allow it to dry.
DRemove the rubber septum completely
Removing the septum opens the bottle and compromises the collection system.

07What minimum body weight is commonly required for a standard whole blood donation?
Practice question Unit: Blood Donor Collections
A50 kg ✓ Correct answer
Fifty kilograms is a commonly used minimum; programmes may apply additional or volume-specific criteria.
B40 kg
Forty kilograms is below the common minimum for a standard adult whole-blood donation.
C30 kg
Thirty kilograms is too low for the standard adult donation volume.
D80 kg
Eighty kilograms is not the usual minimum requirement.

08A haematoma starts to form during the draw. What should the phlebotomist do?
Practice question Unit: Complications of Phlebotomy
ARelease the tourniquet, remove the needle and apply pressure ✓ Correct answer
Release venous pressure, stop the puncture and apply direct pressure to limit further bleeding.
BPush the needle deeper
Advancing the needle risks further tissue or vessel injury.
CContinue until all tubes are full
Continuing collection allows the haematoma to enlarge.
DTighten the tourniquet to stop the swelling from spreading
Further tourniquet pressure can worsen continued leakage into the tissues.

09Which action shows cultural sensitivity when drawing blood from a female patient who prefers a female staff member?
Practice question Unit: Communication, Ethics and Professionalism
AExplain that patient preferences are not considered
Dismissing preferences undermines respectful communication and trust.
BProceed without discussing her concern
Proceeding without discussion does not address consent or the expressed concern.
CRefuse to discuss any alternative arrangements
Reasonable alternatives should be explored rather than rejected without discussion.
DDiscuss the preference and arrange a female phlebotomist or an agreed chaperone when possible ✓ Correct answer
Discuss what is acceptable and accommodate the preference when feasible while respecting the patient’s decision.

10Where can a phlebotomist find hazard and handling information for a chemical?
Practice question Unit: Safety, Quality and Risk Management
APatient chart
A patient chart contains clinical information, not the chemical product hazard specification.
BSafety Data Sheet (SDS) ✓ Correct answer
The SDS describes hazards, safe handling, storage, first aid and exposure controls for the chemical.
CRequisition form
A test requisition identifies the requested test, not chemical handling precautions.
DThe tube manufacturer's advertising leaflet
Advertising material does not replace the product safety-data documentation.
