MULTIPLE CHOICE

1. The nurse is assessing the patient’s leg for peripheral vascular disease (PVD) and is unable to palpate the pedal pulse in either foot. Which action will the nurse take first?
A.
Contact the health care provider for further orders.
B.
Request x-ray studies of the lower extremities.
C.
Request that the patient lie flat.
D.
Obtain a Doppler ultrasound device for auscultation.

ANS: D

Feedback
A
This is not a sufficient cause to notify the health care provider.
B
This is not a sufficient cause to warrant radiologic examination without further assessment.
C
Positioning will not affect the assessment of pedal pulses.
D
The Doppler ultrasound device may aid in determining peripheral blood flow.

2. What is the action of pentoxifylline (Trental), a hemorheologic agent used to treat chronic occlusive arteriole disease?
A.
Vasodilates the peripheral arteries
B.
Potentiates the blood clotting mechanism
C.
Increases erythrocyte flexibility
D.
Increases blood viscosity

ANS: C

Feedback
A
Pentoxifylline does not cause vasodilation.
B
Pentoxifylline acts to decrease clotting.
C
Pentoxifylline enhances red blood cell (erythrocyte) flexibility, which reduces blood viscosity. This allows for more blood to perfuse into the tissues. Muscle tissues become better oxygenated and intermittent claudication is reduced.
D
Pentoxifylline decreases blood viscosity.

3. Which assessment verifies increased blood perfusion to the lower extremities?
A.
Toes cool to the touch
B.
Decreased sensation below the knees
C.
Increased amplitude of pedal pulses
D.
Paleness of the foot

ANS: C

Feedback
A
Coolness usually correlates with decreased blood perfusion.
B
Decreased sensation usually correlates with decreased blood perfusion.
C
The pressure of blood as it is pushed against an artery is detected as a pulse. Increased pulse amplitude indicates increased blood flow.
D
Paleness or blanching does not indicate increased blood perfusion.

4. Which patient statement indicates to the nurse that the patient has a good understanding of peripheral vascular disease?
A.
“Symptoms are warning signs of the increased potential to develop diseases.”
B.
“Pharmacologic treatments can reverse the disease process.”
C.
“Surgical interventions will cure the disease.”
D.
“Controlling contributing factors may affect the progression of the disease.”

ANS: D

Feedback
A
PVD is usually a development that is related to other diseases already present in the body.
B
PVD can be controlled but not cured or completely reversed.
C
Surgical interventions will not cure the disease, although it may somewhat control the vascular damage.
D
Patients must be taught the interrelationships between the PVD and other related diseases that they may have, such as diabetes, hypertension, angina, and hyperlipidemia. Control or lack of control of the contributing factors of these related diseases will significantly affect the progression of the PVD.
