VA-BC Vascular Anatomy & Physiology 5

Question 1

Which of the following veins is typically the DEEPEST and most medial vein in the antecubital fossa, often preferred for PICC insertion?

Accepted Answer

Basilic vein

Answer

The basilic vein is the largest and deepest medial vein at the antecubital fossa and is preferred for PICC insertion because of its size and more direct path to central circulation.

Question 2

Collateral circulation refers to:

Accepted Answer

The redundant arterial supply created by anastomoses when a primary vessel is obstructed

Answer

Collateral circulation is the network of alternative vessels that can enlarge and reroute blood flow when a primary vessel becomes occluded, limiting ischemic injury.

Question 3

The mean arterial pressure (MAP) is calculated using which formula?

Accepted Answer

Diastolic + 1/3 (Pulse Pressure)

Answer

MAP = Diastolic BP + 1/3 (Systolic – Diastolic), reflecting that diastole occupies approximately two-thirds of the cardiac cycle at normal heart rates.

Question 4

Venous stasis, endothelial injury, and hypercoagulability are collectively known as:

Accepted Answer

Virchow's Triad

Answer

Virchow's Triad describes the three major risk factors for thrombosis: venous stasis, endothelial damage, and a hypercoagulable state.

Question 5

Which vessel is palpated to confirm arterial versus venous placement when inserting a central venous catheter at the internal jugular site?

Accepted Answer

Common carotid artery

Answer

The common carotid artery is palpated medially to the internal jugular vein and serves as a landmark to avoid arterial puncture during IJ central line insertion.
