Question 1

A patient develops a palpable cord-like induration along the course of a peripheral IV site vein. This finding is MOST consistent with:

Accepted Answer

Thrombophlebitis

Answer

A palpable cord-like induration along a vein indicates thrombophlebitis, where clot formation and inflammation have occurred within the vessel wall.

Question 2

The right lymphatic duct drains lymph from which region of the body?

Accepted Answer

Right upper quadrant of the body

Answer

The right lymphatic duct drains only the right upper quadrant (right arm, right side of head/neck, right thorax), while the thoracic duct drains everywhere else.

Question 3

Which of the following best describes the Windkessel effect?

Accepted Answer

Arterial compliance buffering pulsatile flow into a more continuous flow

Answer

The Windkessel effect describes how elastic large arteries expand during systole and recoil during diastole, converting pulsatile cardiac output into more continuous flow.

Question 4

In ultrasound-guided vascular access, a vein is distinguished from an artery primarily because veins are:

Accepted Answer

Compressible with gentle probe pressure

Answer

Veins collapse (compress) easily with gentle probe pressure because of their low intraluminal pressure and thin walls, unlike arteries which resist compression.

Question 5

Which term describes the phenomenon where flow velocity increases as blood passes through a stenotic vessel segment?

Accepted Answer

Bernoulli effect

Answer

The Bernoulli effect describes the inverse relationship between pressure and velocity; as a stenotic segment narrows, blood must accelerate to maintain flow continuity.
