Q

What artery has these advantages:

  • Good collateral circulation
  • Easy to palpate
  • Less chance of hematoma formation
A

Radial Artery

17
Q

What artery has these advantages:

  • Large and relatively easy to palpate and puncture

Q

Dorsalis pedis arteries are can be used as an alternative for adults. True or False

A

True

21
Q

Measures arterial competency, and should be performed before taking an arterial sample.

A

Modified Allen Test Procedure

22
Q

In assessing the results of the modified allen test, the hand should be flushes pink within 15 minutes. True or False

A

False - 15 seconds

23
Q

Administer anesthetic if necessary (numb the area with 1% epinephrine free lidocaine). True or False

A

True

24
Q

It is important to check the ulnar pulse after the puncture. True or False

A

False - radial pulse

25
Q

Sample integrity may be compromised if it fails to analyze the sample in a
timely manner. True or False

A

True

26
Q

A temporary constriction of the artery

CHOICES:
Vasovagal response, Arteriospasm, HemorrhagE, Thrombus formation

A

Arteriospasm

27
Q

sudden loss of consciousness after the puncture

A

Vasovagal response

28
Q

Patients with coagulation disorder are prone to this

A

Hemorrhage

29
Q

Exposure of blood as little as 10 to 30 seconds can significantly alter the results of blood gases. True or False

A

True

30
Q

The arterial puncture site is more likely to bleed than a venipuncture site because of the higher blood pressure in the arteries. True or False

A

True

31
Q

The use of too much/too little heparin is a sampling error. True or False

A

True

32
Q

It doesn’t need to remove the air bubbles. True or False

A

False - it needs to be removed since it will cause a sampling errror
