1. Which of the following is the best method to assess the subclavian vein with ultrasound?*
- Start scan in transverse plane of vessels
- Place probe above the lateral clavicle and then slide caudally
- Limit the pressure on your probe to avoid collapsing the vein.
- All of the above
2. Which of the following interfere with finding the subclavian vein on ultrasound?*
- The second rib
- The clavicle
- The sternocleidomastoid muscle attachment
- The pleura and air filled lung
3.What is the preferred method of ultrasound guided subclavian vein access?*
- Transverse - because you can only see the vein in this view
- Transverse - because it has the least risk of pneumothorax or hemothorax
- Longitudinal - because you can see both the artery and the vein in this view
- Longitudinal - because decreased risk of perforating the posterior wall of the vein
Ultrasound use in post catheter placement is:*
- A. Can be used to evaluate pleural line for pneumothorax
- B .Line best seen in longitudinal view
- C. Not recommended
- D. Both A and B
5.What is the expected depth when looking for subclavian vessels?*
- Between 3-5
- Less than 1 cm
- Between 2-3 cm
