Free LESI Indications Questions and Answers

Question 1

You are performing an epidural on a with a large abdominal tumor, would you expect this to change your dose of anesthetic used?

Accepted Answer

I would expect us to use less anesthetic

Answer

In this scenario, the presence of a large abdominal tumor can affect the spread and distribution of the anesthetic. The tumor may compress the nerves in the epidural space, resulting in a decreased volume of the space available for the anesthetic to spread. As a result, a smaller amount of anesthetic may be required to achieve the desired effect. Therefore, the correct answer is "I would expect to use less anesthetic".

Question 2

Central ray enters 2" medial to the elevated ASIS and 1and a half inches above the iliac crest for the ____________ Projection

Accepted Answer

AP Oblique

Answer

The given correct answer is AP Oblique. In this projection, the central ray enters 2" medial to the elevated ASIS and 1 and a half inches above the iliac crest. This positioning allows for visualization of the lumbar spine and sacrum in an oblique angle, which helps in evaluating specific structures and detecting any abnormalities.

Question 3

The patients body is rotated at ___________ degrees  for the AP Oblique Projections

Accepted Answer

45

Answer

The patient's body is rotated at 45 degrees for the AP Oblique Projections. This specific angle allows for a better visualization of certain anatomical structures or organs that may be obscured in other projections. By rotating the body at 45 degrees, it provides a different perspective and helps to highlight specific areas of interest for diagnostic purposes.

Question 4

How many pairs of spinal nerves do we have?

Accepted Answer

31

Answer

We have 31 pairs of spinal nerves. The spinal nerves are part of the peripheral nervous system and are formed by the combination of dorsal and ventral roots. There are 31 pairs of spinal nerves in total, with each pair connected to a specific segment of the spinal cord. These nerves are responsible for transmitting sensory information from the body to the brain and carrying motor commands from the brain to the muscles and organs.

Question 5

Where do preganglionic fibers of the parasympathetic nervous system end?

Accepted Answer

In the organ they innervate

Answer

Preganglionic fibers of the parasympathetic nervous system end in the organ they innervate. Unlike the sympathetic nervous system, which has a chain of ganglia outside the target organs, the parasympathetic fibers have shorter preganglionic fibers organs, that directly synapse with postganglionic neurons in the target organ. This allows for more specific and localized control of the parasympathetic response within the organ itself.
