Summary questions

Question 1

Arterial blood gas sampling is used:

	instead of phlebotomy in young patients with strong pulses
	only in patients with pulmonary disease
	only in patients with renal disease
	to assess lung ventilation, tissue oxygenation, and acid base status

Question 2

The radial artery is:

	found in the deep tissues under the flexor carpi radialis tendon
	in the superficial subcutaneous tissues on the radial side of the wrist
	medial and deep to the flexor carpi radialis
	in the midline of the wrist

Question 3

The most common complication of arterial blood gas sampling is:

	obstructing thrombus in the artery
	infection
	hematoma
	radial nerve injury

Question 4

The syringe is filled during sampling by

	drawing up on the plunger once in the artery
	allowing arterial pressure to fill the syringe to about 1 ml
	squeezing the forearm
	applying pressure to the artery

Question 5

The most common reason for a difficult and painful arterial puncture is:

	anatomic variability
	faulty equipment
	airlock in the syringe
	missing the artery on the initial puncture and then probing deeper
