Question

In adults, the following placement of an indwelling artery catheter (A-Line) is LEAST preferred

A) Brachial
B) Radial
C) Dorsalis Pedis
D) Femoral

Answer 1

The LEAST preferred placement of an indwelling artery catheter (A-Line) in adults is the Dorsalis Pedis (C) placement. The brachial, radial, and femoral arteries are larger and more commonly used due to easier access, better stability, and reduced risk of complications.

Step-by-step explanation:

The LEAST preferred placement of an indwelling artery catheter (A-Line) in adults is the Dorsalis Pedis (C) placement.

The Dorsalis Pedis artery is located on the top of the foot, and it has a smaller diameter compared to other arteries like the brachial, radial, and femoral arteries. This makes it more difficult to accurately place and secure the catheter.

On the other hand, the brachial (A), radial (B), and femoral (D) arteries are larger and more commonly used for A-Line placements due to easier access, better stability, and reduced risk of complications.
