1. Prior to a vascular interventional procedure, which
laboratory value is most critical to assess for bleeding risk?
A) Hemoglobin
B) Platelet count
C) Creatinine
D) White blood cell count
Answer: B
*Rationale: Platelet count is critical to assess bleeding risk.
Thrombocytopenia (platelets <50,000/μL) significantly increases
bleeding risk. While hemoglobin (A) indicates baseline anemia,
1
,platelet count directly impacts clotting ability. Creatinine (C)
assesses renal function, and WBC (D) indicates infection risk .*
2. Which medication is routinely held prior to a vascular
interventional procedure due to increased bleeding risk?
A) Metformin
B) Lisinopril
C) Warfarin (Coumadin)
D) Levothyroxine
Answer: C
*Rationale: Warfarin (vitamin K antagonist) is typically held 3-5
days prior to elective procedures to reduce bleeding risk.
Bridging with heparin may be used for high-risk patients.
Metformin (A) is held for contrast-induced nephropathy risk, not
bleeding. Lisinopril (B) is an antihypertensive that may be
2
,continued or held based on blood pressure. Levothyroxine (D) is
continued .*
3. The most common complication of arterial vascular access
is:
A) Arteriovenous fistula
B) Pseudoaneurysm
C) Retroperitoneal hemorrhage
D) Hematoma
Answer: D
*Rationale: Hematoma is the most common complication of
arterial access (occurring in 2-10% of procedures). It results from
inadequate hemostasis or accidental arterial puncture.
Pseudoaneurysm (B) occurs in 0.5-2% of cases. Retroperitoneal
hemorrhage (C) is a rare but serious complication (0.1-0.5%).
Arteriovenous fistula (A) is also rare .*
3
, 4. Rutherford category 1 for contrast-induced acute kidney
injury (CI-AKI) requires a serum creatinine increase of:
A) 0.5 mg/dL or 25% above baseline
B) 1.0 mg/dL or 50% above baseline
C) 2.0 mg/dL or 100% above baseline
D) No change from baseline
Answer: A
*Rationale: Rutherford category 1 (low risk) is defined as serum
creatinine increase of 0.5 mg/dL or 25% above baseline within
48 hours of contrast administration. Category 2 (moderate)
requires 1.0 mg/dL or 50% increase requiring dialysis. Category
3 (severe) requires dialysis .*
5. For a patient with estimated glomerular filtration rate
(eGFR) <30 mL/min, the maximum contrast dose should be:
