Question 1

A patient requires urgent intravenous access but peripheral veins are inaccessible. Which intraosseous site is preferred in adults during emergency resuscitation?

Accepted Answer

Proximal humerus

Answer

The proximal humerus is the preferred intraosseous site in adults during emergency resuscitation due to higher flow rates and ease of access.

Question 2

During a lumbar puncture, which anatomical landmark is used to identify the correct intervertebral space to avoid spinal cord injury?

Accepted Answer

Iliac crest at L3-L4

Answer

The iliac crest corresponds to the L3-L4 interspace, below the spinal cord termination (conus medullaris at L1-L2), making it safe for lumbar puncture.

Question 3

A surgeon performing a central line via the right internal jugular vein should aim the needle toward which landmark?

Accepted Answer

Ipsilateral nipple

Answer

For right internal jugular central line insertion, the needle is directed toward the ipsilateral nipple at a 45-degree angle to the skin.

Question 4

Which complication is most immediately life-threatening following subclavian central venous catheter insertion?

Accepted Answer

Tension pneumothorax

Answer

Tension pneumothorax is the most immediately life-threatening complication as it causes rapid cardiovascular collapse if not promptly decompressed.

Question 5

When performing needle thoracocentesis for tension pneumothorax, the needle is inserted at which location?

Accepted Answer

2nd intercostal space, midclavicular line

Answer

Emergency needle decompression for tension pneumothorax is performed at the 2nd intercostal space in the midclavicular line to access the apex of the pleural cavity.
