Question 1

Local anesthetics are weak ____

Answer 1

bases

Question 2

What are the 4 basic transducer manipulation techniques?

Answer 2

Pressure (P): various degrees of pressure applied to transducer that are translated onto the skin

Alignment (A): sliding the transducer defines the lengthwise course of the nerve and reference structures

Rotation (R): the transducer is turned in either a clockwise or counterclockwise direction to optimize the image of the nerve and needle

Tilting (T): the transducer is tilted in both directions to maximize the angle of incidence of the ultrasound beam to the target nerve, thereby maximizing reflection and optimizing image quality
