1. What is the main challenge for providers to become proficient when learning ultrasound guided regional anesthesia? Identifying the needle tip 2. What nerve is most missed with an axillary block? Musculocutaneous 3. Does the axillary block affect the axially nerve? No 4. Which brachial plexus approach will cause ipsilateral diaphragmatic paralysis? Interscalene 5. Why do we use low frequency for ultrasound to penetrate deep tissues? 6. Why do deep tissues have less resolution when viewed on ultrasound? 7. Why do nerve trunks appear hypoechoic on ultrasound when more proximal? Due to increased water content of the nerve bundles 8.
