Chapter 25: Drugs Used to Treat Peripheral Vascular Disease
Complete Chapter Questions With Answers
Sample Questions Are Posted Below
MULTIPLE CHOICE
| 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
The Doppler ultrasound device may aid in determining peripheral blood flow. This is not a sufficient cause to notify the health care provider and does not warrant radiologic examination without further assessment. Positioning will not affect the assessment of pedal pulses.

| a. | Vasodilates the peripheral arteries |
| b. | Potentiates the blood-clotting mechanism |
| c. | Increases erythrocyte flexibility |
| d. | Increases blood viscosity |
ANS: 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. Pentoxifylline does not cause vasodilation. Pentoxifylline acts to decrease clotting and decreases blood viscosity.

NOT: CONCEPT(S): Clinical Judgment; Perfusion; Clotting
| 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
The pressure of blood as it is pushed against an artery is detected as a pulse. Increased pulse amplitude indicates increased blood flow. Coolness and decreased sensation usually correlate with decreased blood perfusion. Paleness or blanching does not indicate increased blood perfusion.

NOT: CONCEPT(S): Clinical Judgment; Perfusion; Clotting
| 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
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. PVD is usually a development that is related to other diseases already present in the body. PVD can be controlled but not cured or completely reversed. Surgical interventions will not cure the disease, although it may somewhat control the vascular damage.
