Phlebotomy Essentials 4Th Edition, Chap 12

Front 1

abducted

Back 1

away from the body (position of arm fro ABGs collection)

Front 2

ABGs

Back 2

arterial blood gases
venous blood varies relative to metabolic needs
arterial blood consistent through out body

Front 3

Allen Test

Back 3

test before radial puncture
positive- okay to puncture
neg-no puncture

Front 4

arteriospasm

Back 4

reflex(involuntary) contraction of artery

Front 5

brachial artery
femoral artery
radial artery
ulnar artery

Back 5

-brachial-medial anterior aspect of anticubital fossa(2nd choice arterial puncture)
-femoral-superficially in groin, lateral to the pubis bone(largest used for arterial puncture)
-radial-thumb side of wrist(1st choice arterial puncture)
-ulnar-opposite side from radial artery(never used)

Front 6

collateral circulation

Back 6

the site is supplied from more than one artery(circulation maintained if damaged or obstructed)

Front 7

steady state

Back 7

stable..no exercise suctioning or respirator changes

Front 8

FiO2

Back 8

fraction of inspired oxygen
room air is 0.21

Front 9

L/M

Back 9

liters per minute
flow rate for ventilation status

Front 10

ABGs measured

Back 10

pH, PO2, PCO2, HCO, O2 saturation, Base excess/deficit
(see chart pp454for description and ranges)

Front 11

biggest advantage of using radial artery for ABGs

Back 11

presence of collateral circulation

Front 12

other sites for arterial specimens

Back 12

scalp, umbilical arteries in infants, dorsalis pedis in adults

Front 13

needles for ABGs collection size?

Back 13

22 or smaller

Front 14

ABG Requisition info?

Back 14

full name
record or ID#
age/DOB
room #/PT location
Date & Time collection
FiO2 or L/M
body temp
respiration rate
clinical indication (ie..FiO2 or ventilation change)
your initials
phys name
also may be required:
ventilation status
method of ventilation
site and procedure
PT activity and position
working diag and ICD code

Front 15

electrolite should not be cooled
why?

Back 15

it affects potassium levels

Front 16

acceptable anitcoagulant for ABGs

Back 16

heparin
(too much can result in acidosis, too little can result in clotting of specimen)

Front 17

ABG rejection criteria

Back 17

air bubbles
clotted
hemolysis
improper/absent labeling
improper transportation temp
inadequate volume for test (QNS)
prolonged delay in delivery to lab
use of wrong syringe

Front 18

hazards and complications assoc with Aterial puncture
list 7

Back 18

Arteriospasm
discomfort
infection
hematoma
numbness
thrombus formation
vasovagal response

Front 19

vasovagal response is?
caused by?

Back 19

faintness/loss of conciousness related to hypotension
-nervous sys response(increased vagus nerve activity) to abrupt pain or trauma

Front 20

sampling errors
list 7

Back 20

air bubbles
delay in analysis
improper mixing
improper syringe
venous blood (not arterial)
use improper anticoagulant
too much/little heparin
