1. Which vein is the most common first choice for peripheral
IV cannulation in an adult?
A) Basilic vein
B) Cephalic vein
C) Median cubital vein
D) Dorsal venous arch
Answer: C) Median cubital vein
Rationale: The median cubital vein is large, superficial, and well-
anchored, making it ideal for venipuncture. It also minimizes risk
of nerve injury compared to basilic/cephalic veins.

,2. Which layer of a blood vessel is penetrated first during IV
insertion?
A) Tunica adventitia
B) Tunica media
C) Tunica intima
D) Tunica externa
Answer: C) Tunica intima
Rationale: The needle passes through skin, then the tunica intima
(innermost layer) before entering the lumen. Tunica media is
smooth muscle; adventitia is outer connective tissue.
3. The brachial artery lies in proximity to which vein,
increasing risk of accidental arterial puncture?
A) Basilic vein
B) Cephalic vein
C) Median cubital vein
D) Radial vein
2
,Answer: A) Basilic vein
Rationale: The basilic vein runs near the brachial artery and
median nerve. Accidental arterial puncture or nerve injury is a
known risk with basilic access.
4. Valves in veins serve what primary purpose?
A) Prevent backflow of blood
B) Increase venous pressure
C) Oxygenate venous blood
D) Regulate temperature
Answer: A) Prevent backflow of blood
Rationale: Venous valves are one-way structures that prevent
retrograde flow, especially important in lower extremities
against gravity.
5. Which vein is NOT appropriate for lower extremity IV
placement in an ambulatory adult without special order?
A) Greater saphenous vein
3
, B) Small saphenous vein
C) Dorsal venous arch of foot
D) Femoral vein
Answer: D) Femoral vein
Rationale: Femoral vein access increases risk of DVT and
infection; it is reserved for emergency or central line placement.
Lower extremity IVs generally require MD order due to
thromboembolism risk.
6. The cephalic vein is located on which aspect of the arm?
A) Medial (ulnar side)
B) Lateral (radial side)
C) Posterior
D) Deep midline
Answer: B) Lateral (radial side)
Rationale: The cephalic vein runs along the radial (thumb) side of
the forearm and arm; basilic is medial (ulnar side).
