Question

Which technique, ultrasound, peripheral nerve stimulation (PNS), or both, is associated with the advantage of requiring fewer needle passes during procedures?

A) Ultrasound
B) Peripheral nerve stimulation (PNS)
C) Both ultrasound and peripheral nerve stimulation (PNS)

Answer 1

The technique associated with requiring fewer needle passes during procedures is ultrasound.

Step-by-step explanation:

The technique associated with requiring fewer needle passes during procedures is ultrasound. Ultrasonography is an imaging technique that uses high-frequency sound waves to generate real-time images of anatomy and physiology. It is the least invasive of all imaging techniques and is commonly used in sensitive situations like pregnancy. Although it has some limitations, such as being operator-dependent and unable to penetrate bone and gas, ultrasound can significantly reduce the number of needle passes required during procedures.
