Arterial Line Placement (Anesthesia) - Test
Please select only one answer for each question.
Question 1
Which of the following statements is true about Allen’s test?
a.
It accurately assesses collateral arterial flow in the hand.
b.
Patients with an abnormal Allen’s test are more likely to have complications from
radial artery cannulation.
c.
Allen’s test correlates with dye studies of arterial blood flow to the hand.
d.
All of the above
e.
None of the above
Question 2
Which of the following statements is/are TRUE?
a.
Radial artery occlusion is rare after radial artery line placement.
b.
Ischemic complications usually accompany radial artery occlusion associated with
radial artery line placement.
c.
Infection following arterial line placement is common and requires close attention.
d.
All of the above
e.
None of the above
Question 3
A 52-year-old woman who is right-hand dominant presents for elective repair of a 6 cm
suprarenal abdominal aortic aneurysm during general anesthesia. Her medical history is
significant for left sided breast cancer treated with modified radical mastectomy and axillary
node dissection. Additionally, she has insulin-dependent type II diabetes and hypertension for
which she takes lisinopril.
Placement of an arterial catheter allows for the direct measurement of all of the following
except:
a.
Glucose
1
b.
pH
c.
Intravascular volume
d.
Blood pressure
e.
Heart rate
Question 4
A 40-year-old man is admitted to the ICU after a rock climbing accident involving bilateral upper
extremity trauma. He has a femoral artery catheter for blood pressure monitoring.
As compared to a radial artery, which of the following complications is increased with a femoral
artery approach?
a.
Infection
b.
Lack of accuracy
c.
Nerve injury
d.
Pseudoaneurysm formation
e.
Ischemia
Question 5
Which of the following statements is/are TRUE?
a.
The radial artery is the most common site of arterial cannulation.
b.
Infection rates are lower with radial artery cannulation than with femoral artery
cannulation.
c.
The radial artery is a terminal branch of the brachial artery.
d.
A and C
e.
A and B
Question 6
A 52-year-old woman who is right-hand dominant presents for elective repair of a 6 cm
2
suprarenal abdominal aortic aneurysm during general anesthesia. Her medical history is
significant for left sided breast cancer treated with modified radical mastectomy and axillary
node dissection. Additionally, she has insulin-dependent type II diabetes and hypertension for
which she takes lisinopril.
You decide to place an arterial line for monitoring. Which of the following is a relative
contraindication to placement of an arterial catheter?
a.
Right hand dominance
b.
Previous axillary node dissection
c.
Diabetes
d.
Ulnar placement
e.
Positive Allen's test
Question 7
A 52-year-old woman who is right-hand dominant presents for elective repair of a 6 cm
suprarenal abdominal aortic aneurysm during general anesthesia. Her medical history is
significant for left sided breast cancer treated with modified radical mastectomy and axillary
node dissection. Additionally, she has insulin-dependent type II diabetes, and hypertension for
which she takes lisinopril.
After several unsuccessful attempts at radial artery cannulation, you decide to place the arterial
line in the brachial artery in the right arm. Under ultrasound guidance, brachial artery
cannulation proceeds easily, although the patient complains of a brief, sharp pain as the
catheter is inserted. The operation is uneventful, and the patient is transferred to the ICU for
overnight monitoring. When she is fully awake, she complains of pain in her index finger and
demonstrates decreased grip strength in her right hand. All other examination findings are
unremarkable. Which of the following nerves was most likely injured?
a.
Ulnar
b.
Radial
c.
Median
d.
Brachial
e.
Axiliary
