Chapter 14 Arterial Puncture Procedures

Arteriospasm is defined as:

Artery contraction resulting from pain, irritation by the needle or anxiety

steady state means that the patient has

Had no suction or respirator changes

what can cause erroneous ABG values

The presence of air bubbles in the specimen, delay in analysis exceeding 30 minutes, and inadequate mixing results in microclots.

Sudden fainting during arterial puncture is all of the following EXCEPT

related to hypoglycemia

the first choice location for performing arterial puncture is the

radial artery

the preferred and most common site for arterial puncture is the:

radial artery

the most common needle size for routine radial ABG specimen collection is

22 gauge

acceptable angle of needle insertion for radial ABGs

45 degrees

which of the following is an acceptable angle of needle insertion for drawing radial arterial blood gases

45 degrees

the proper angle of needle insertion for drawing femoral arterial blood gas is :

90 degrees

heparin is used in arterial sample collection to:

prevent clotting of the specimen

the following is NOT a blood gas component

PO4

Positioning of the arm for radial arterial blood gas specimen collection includes all of the following EXCEPT:

arm adducted

which of the following is the most common arterial puncture complication even when proper procedure is used

arteriospasm

complications associated with arterial puncture

arteriospasm, hematoma, infection

arterial puncture site selection is based on all of the following EXCEPT:

available equipment in the room

the blood gas parameter HCO3 measures the amount of:

bicarbonate circulating in the blood

the purpose of the modified Allen test is to determine

collateral circulation is present

which of the following is the best way to tell if a specimen is arterial? as the specimen is collected, the blood will:

pump into the collection syringe

the primary reason for performing arterial puncture is to

evaluate blood gases

which artery is generally easiest to access during low cardiac output

femoral

the biggest advantage of choosing the radial artery for arterial blood gas collection is:

good collateral circulation is present

what constitutes a positive modified Allen test, the

hand color returns to normal in 15 seconds

the thumb should not be used to feel for the artery because it:

has a pulse

ABG supplies include

heparinized syringes, 22 gauge needle,

all of the following can affect the integrity of a blood gas sample EXCEPT:

increased vagus nerve activity

a proper cleaning solution for preparing an arterial puncture site is

isopropyl alcohol

what should the phlebotomist do if the pulse is absent or faint following arterial blood collection

notify the patient's nurse or lab supervisor

ABG parameters include

pH,PaCO2, O2 saturation

which of the following would cause you to suspect that a thrombus had formed in the artery while you were collecting an ABG

the pulse distal to the site is very weak

the radial artery is located in the :

thumb side of wrist

when performing the modified Allen test, which artery is released first

ulnar

all of the following would cause an arterial blood gas specimen to be rejected EXCEPT:

unavoidable delay in collection

patient complications associated with arterial puncture include all of the following EXCEPT:

venostasis
