10 Laboratory Operations
1 A phlebotomist must verify patient identity using which two identifiers
A Room number and diagnosis
B Name and date of birth
C Physician and nurse name
D Bed number and age
Answer: B Name and date of birth
Using at least two identifiers ensures correct patient identification and reduces medical
errors
,2 The most appropriate antiseptic for routine venipuncture is
A Hydrogen peroxide
B Iodine
C 70 percent isopropyl alcohol
D Sterile water
Answer: C 70 percent isopropyl alcohol
Alcohol effectively reduces skin bacteria and is standard for routine blood collection
3 The vein most commonly used for venipuncture is
A Basilic vein
B Cephalic vein
C Median cubital vein
D Radial vein
Answer: C Median cubital vein
It is well anchored and less prone to complications
4 The correct order of draw is designed to
A Prevent hemolysis
B Avoid contamination between tubes
C Reduce patient pain
D Increase blood flow
Answer: B Avoid contamination between tubes
Additives from one tube can affect results in another if order is incorrect
5 Which tube is drawn first in a standard venipuncture
A EDTA tube
B Serum tube
C Blood culture bottle
D Heparin tube
Answer: C Blood culture bottle
Sterility is critical so cultures are collected first
6 The purpose of EDTA in blood collection tubes is to
A Promote clotting
,B Prevent clotting
C Preserve glucose
D Destroy bacteria
Answer: B Prevent clotting
EDTA binds calcium to inhibit clot formation
7 The needle bevel should be positioned
A Downward
B Sideways
C Upward
D Backward
Answer: C Upward
This allows smoother entry into the vein
8 What is the maximum recommended time a tourniquet should be applied
A 30 seconds
B 1 minute
C 2 minutes
D 3 minutes
Answer: B 1 minute
Prolonged application can cause hemoconcentration
9 Which complication results in blood pooling under the skin
A Hematoma
B Hemolysis
C Thrombosis
D Infection
Answer: A Hematoma
Occurs when blood leaks into surrounding tissue
10 The best site for capillary puncture in adults is
A Palm
B Heel
C Fingertip
, D Wrist
Answer: C Fingertip
Usually the middle or ring finger is used
11 The order of draw for capillary collection begins with
A Serum tubes
B EDTA tubes
C Blood gases
D Coagulation tubes
Answer: C Blood gases
Minimizes exposure to air and ensures accurate results
12 A collapsed vein may be caused by
A Using a large needle
B Excessive vacuum
C Patient hydration
D Proper technique
Answer: B Excessive vacuum
Too much suction can cause the vein to collapse
13 Which gauge needle is most commonly used for adult venipuncture
A 18 gauge
B 21 gauge
C 25 gauge
D 27 gauge
Answer: B 21 gauge
Provides a balance between flow and patient comfort
14 Hemolysis is the breakdown of
A Platelets
B Plasma
C Red blood cells
D White blood cells
