MLSP VENI Flashcards
The ideal time to collect blood from a patient
Basal state
Spontaneous loss of consciousness caused by
insufficient blood flow to the brain
Fainting
Paleness of the skin, hyperventilation,
lightheadedness, dizziness, nausea, feeling of
warmth/cold, clammy skin
Syncope
Increase in the number formed elements in blood
due to decrease plasma volume
HEMOCONCENTRATION
Small, nonraised red hemorrhagic spots, Patients that have platelet disorders are common to this
PETECHIAE
If the patient is nauseated, instruct the patient to
breathe deeply and slowly; apply cold compresses
to the patient’s forehead
VOMITTING
May result in loss of movement to the arm or hand
NERVE INJURY
Shooting pain, electric-like tingling or numbness,
running up or down the arm or in the fingers of the
arm
NERVE INJURY
Formation of blood clots inside the lumen of the vein due to trauma
THROMBOSIS OF VEINS
Inflammation of the vein caused by thrombus
THROMBOPHLEBITIS
Blue or black skin discoloration commonly due to
repeated trauma or puncture of the veins
HEMATOMAS
• Damaged veins
• Hematoma (you can collect blood on the same side
or part of the body, just not the exact vein; avoid
the vein with hematoma)
• Edema
AREAS TO AVOID
Burns (prone to infection), Scars (more painful), and
tattoos (interference in the results)
• Arm on the same side of a mastectomy
• IV Therapy
AREAS TO AVOID
The needle is too small
- The gauge is not right
- The plunger is pulled too fast
- Shaking of the tubes vigorously
- Forcing blood into the evacuated tube
- Alcohol did not dry
HEMOLYSIS
This is caused by transient rise
in chylomicrons following a meal containing fat
LIPEMIA OR LACTESCENSE
have 2 choices of the median vein
M pattern
1 choice of median vein
H pattern
Most patients have this kind of pattern; 70%
H pattern
Veins on the dorsal portion of the hand
Other sites
Veins on the underside of the wrists, however, should never be used for venipuncture
OTHER SITES
Located near the center; preferred vein for
venipuncture because it is large, stationary, least
painful due to less nociceptor and bruises less easily
MEDIAN CEPHALIC VEIN
Lateral aspect; second choice; hard to palpate but
fairly well anchored and the only vein can be felt in
obese
CEPHALIC VEIN
Medial side; not well anchored and rolls easily, high
risk of puncturing median cutaneous nerve or the
brachial artery
BASILIC VEIN
T or F
The preferred site for venipuncture is the
antecubital fossa located anterior and below the
bend of the elbow.
Trueeee
T or F
3 Veins: Median, Cephalic, and Basilic Vein
True
The most frequently performed procedure in
phlebotomy
Venipuncture
T or F
Requisitions must contain certain basic information
to ensure that the sample drawn and the test
results are correlated with the appropriate patient
True
T or F
Patient should be given a brief explanation of the
procedure. They should not be told that the procedure will be painless
True
Impedes venous blood flow, causing blood to accumulate in the veins making them more
easily located. Provides a larger amount of blood for collection
tourniquet
