Urine
37
The wastes will have to be [?] following institutional policy.
decontaminated
38
Most clinical laboratories follow the following: - Soaking the sample in [?] or [?] for at least 15 minutes - [?] - Pickup by a [?]
- 5% Lysol or 10% sodium hypochlorite solution - Autoclaving - certified hazardous waste company
39
Laboratory sinks must be disinfected using a [?] on a DAILY basis.

40
Capillary puncture is indicated for
adults and older children
41
Available veins are [?] or must be saved for other procedures such as chemotherapy.
fragile
42
Several unsuccessful venipunctures have been performed and the requested test can be collected by
capillary puncture
43
The patient has [?] or clot-forming tendencies.
thrombotic
44
The patient is [?] or has an intense fear of needles
apprehensive
45
There are no [?] veins.

46
To obtain blood for point-of-care test procedures such as
glucose monitoring
47
For [?] or scarred patients.

[?] patients.
Obese
49
preferred method for infants and very young children (possibly younger than 2 years)
capillary puncture
50
Infants have a small blood volume which means removing quantities of blood typical for venipuncture or arterial puncture can lead to
anemia
51
Large quantities removed rapidly can cause
cardiac arrest
52
Obtaining blood from infants and children by venipuncture is difficult and may damage [?]
veins and surrounding tissues
53
Locating [?] that are large enough to accept even a small-gauge needle is difficult in these patients
superficial veins
54
Puncturing [?] can result in hemorrhage, venous thrombosis, infection and gangrene
deep veins
55
An infant or child can be injured by the [?] used while performing a venipuncture
restraining method
56
Capillary blood is the preferred specimen for some tests, such as
newborn screening tests and capillary blood gases
57
In using the syringe, [?] creates a vacuum within the barrel.
pulling the plunger
58
The [?] created while a needle is in the patient’s veins fills the syringe with blood.
vacuum
59
Take note that the larger the syringe,
the greater amount of vacuum obtained.
60
difficult-to-draw patients (veins are fragile, thin, or “rolly” veins that tend to collapse – pediatric and geriatric patients)
61
sample collection from the surface veins of the feet or back of the hands
Syringe Method
62
special procedures (blood is drawn and must be transferred to a different container)
Syringe Method
63
Too large a vacuum has the tendency to pull too hard on the vein leading it to
collapse
64
The use of syringe larger than [?] is not recommended.
10-15 mL
65
The assembly allows one point of the needle to be inserted into the vein, while the other point punctures the rubber stopper of the tube.
Evacuated System
66
The vacuum present inside the tube will be replaced by blood when the needle is inside the lumen of the vein.
Evacuated System
67
This method of collection is indicated for large volume collection but is not recommended for small, fragile veins.
Evacuated System
68
This method of collection is indicated for large volume collection but is not recommended for small, fragile veins.
Evacuated System
69
is a specialized liquid connective tissue comprising of plasma and formed /cellular elements.
Blood
70
In a tube containing anticoagulated whole blood, centrifugation yields three layers: the pale-yellow supernatant referred to as the thin white layer known as the lastly
- plasma - buffy coat - packed red cell fraction -
71
Plasma makes up 55% of blood volume.
71
Plasma makes up [?] of blood volume.
55%
72
The major constituent of plasma is [?]; followed by [?] and [?].
- water (91.5%) - plasma proteins (7%) - other solutes (1.5%)
73
The proteins dissolved in plasma are
albumin (54%), globulins (38%), fibrinogen (7%) and the others at 1%.
74
The other solutes found in plasma are
electrolytes, nutrients, gases, regulatory substances and some metabolic waste products
75
A blood sample in a tube that has no anticoagulant yields [?] as its supernatant after centrifugation.
serum
76
is yellow in color and differs from plasma because of the absence of coagulation proteins such as fibrinogen
Serum
