Question	Answer
Arteriospasm is defined as	artery contraction due to pain, irritation by a needle, or anxiety
Formation of a thrombus during arterial puncture can result from an	injury to the arterial wall
Significantly inaccureate ABG values can result from	microclots that are undetected
The inegrity of a blood gas specimen can be affected by	ratio of blood to anticoagulant
The thumb shoud not be used to feel for an artery because it	has a pulse
A patient complication associated with arterial	numbness
The radial artery is located in the	thumb side of the wrist
Why is arterial blood better for blood gas determination than venous blood	composition of arterial blood is more consistent
The blood gas parameter HCO3 measures the amount of	bicarbonate circulating in the blood
Which of the following test requies an arterial specimen	Blood gases
Which of the following analytes is routinely part of a blood gas analysis	PaO2
Arterial blood gas evaluation would most likely be performed on a patient with	pulmonary disease
Arterial puncture instruction typically includes	observation of procedures
Arterial puncture site selection is based on the	existence of collaterial circulation
One reason to favor a site as a choice for arterial puncture is	that it has very little tissue covering the artery
The preferred and most common site for arterial puncture is the	radial artery
Which aratery is generally easiest to access during low cardiac output	femoral
The biggest advantage of choosing the radial artery for ABG collection is that	it usually has good collateral circulation
Which of the following is a disadvantage of using the radial artery for ABG collection	it is small and difficult to feel
Which of the following is an advantage of using the brachial artery for arterial blood collection	it is large and fairly esy to palpate
One disadvantage of puncturing the brachial artery is that it	lies near the median nerve
Which arterial site poses the greatest risk of infection	femoral
Arterial specimens can also be collected from the	dorsalis pedis arteries of most adults
Supplemental information on an arterial blood gas requisition typically includes	patient activity and body postion
Which of the following is requied for ABG collection	1- to 5-mL self-filling syringe
Arterial blood gas specimens are collected in syringes rather than tubes because	evacuated tube pressure can change results
PPE used when collecting arterial specimens includes	lab coat and gloves
Commercialloy prepared arterial smapling kits rarely contain a	1% lidocaine-filled syringe
Heparin is used in arterial sample collection to	prevent clotting of the specimen
Lidocaine is sometimes used during arterial puncture	anesthetize the site prior to the puncture
Prior to ABG collection, a patient should have been in a steady state for at least	20 to 30 minutes
A patient in a steady state for ABG collection has	had no suction changes in 20 minutes
The purpose of performing the modified Allen test prior to arterial specimen collection is to	determine collateral ciuculation
When performing the modified Allen test, which artery is released first	Ulnar
What constitutes a positive modified Allen test	the hand color returns to normal in 15 seconds
Which of the following is proper procedure if the Allen test is negative	check for collateral circulation in the other arm
A patient who has collateral circulation	has multiple arteries supplying blood to an area
Which of the following actions assoicated with the radial ABG procedure are in the correct order	assess, positon, clean, puncture, fill, expel, label
Which one of the following radial ABG specimen collection steps is optional	administration of local anesthetic
Positioning of the arm for radial ABG specimen collection includes	extending the wrist approximately 30 degrees
Which of the following would be a reason to terminate an arterial puncture	the patient's complaints of extreme pain and discomfort
In performing arterial puncture, the neelde must be directed	away from the hand, facing the blood flow
Which of the following is an acceptable angle of needle insertion for drawing radial arterial blood gases	45 degress
The typical needle used to collect blood from a radial artery is	22-gauge, 1 inch
How do yo know when you have "hit" an artery during arterial blood gas collection	A flash of blood appears in the syringe nub
Which of the following is the best way to tell if a specimen is arterial? As the specimen is collected the blood will	pump or pulse into the syringe
As soon as the needle is withdrawn following ABG specimen collection the	apply site pressure for 3 to 5 minutes
Proper specimen handling immediately following collection involves	mixing the specimen to prevent clotting
After performing arterial puncture, the therapist should check the pulse	distal to the puncture site
What should thetherapist do if the pulse is absent or faint following ABG collection	Notify the patient's nurse or the lab supervisor
Which of the following is a common arterial puncture complication even when proper procedure is used	arteriospasm
Blood gas specimen rejection criteria include	improper lableing or missing lable inadequate volume of the speciemn visible hemolysis of the specimen
Which of the following is most likely to cause erroneous ABG results	microclots present in the specimen
ABG	Arterial blood gases
Allen test	A simple noninvasive test to assess collateral circulation before collecting a blood specimen from the radial artery
Brachial artery	artery located in the medial anterior aspect of the antecubital fossa near that insertion of the biceps muscle; the second choice for arterial puncture
Collateral circulation	An area supplied with blood from more than one artery so that circulation can be maintenaced if one vessel is obstructed
Fi02	Fractional inspired oxygen as in oxygen therapy
L/M	Liters per minute ,as in oxygen therapy
Radial artery	The artery located at the thumb side of the wrist, which is the first choice and most common site used for arterial puncture
Steady state	stable condition required before obtaining blood gas specimens; that is a condition in which there has been no exercise, suctioning or repsirator change for at least 20 to 30 minutes
Ulnar artery	artery located on the medial aspect or little finger side of the wrist
Arteriospasm	A reflex (involuntary) contraction of the artery that can be caused by pain or irritation during needle penetration of the artery muscle or that may result from a patient's anxiety during arterial puncture
