26
What type of angioplasty is done in patients with PAD?
Angioplasty with or without stenting
27
Patients with PAD need to do what about smoking and exercise?
They need to eliminate smoking and do progressive strenuous exercise
28
True or False: | A patient with PAD should not have a surgical revascularization with bypass?
False: | These patients benefit from revascularization with bypass
29
If a patient is diabetic with PAD what is their dosage of aspirin?
375 mg- they need a higher dose than patients without diabetes
30
How does chronic venous insufficiency or CVI normally occur?
From vein pathology, such as vascular incompetence, causing venous stasis and increased venous pressure in the lower extremities
31
What are the three things that diagnose CVI?
History, physical and duplex ultrasound
32
Patients with CVI tend to be at higher risk for what?
DVTs
33
A patient who has CVI is more comfortable with their legs doing what?
Elevated

If you do what you are at a higher risk for CVI?
Standing for a long time each day
35
What gender is at a higher risk for developing CVI?
females
36
What are the other 7 risk factors for CVI?
``` Varicose veins Smoking Inactivity Aging Obesity Pregnancy Thrombophlebitits ```
37
When a patient has CVI: What type of edema do they experience?
Lower extremity edema that increases with standing
38
What type of leg discomfit do patients with CVI experience?
Itching, dull leg discomfort that increases with standing
39
What type of ulcerations do patients with CVI experience?
Stasis ulcerations: with irregular boarders

48
What four things do you use for planning in PVD and CVI patients?
- Promote wound healing - Manage pain - Promote tissue perfusion - Optimize activity tolerance
49
What are the four implementation you should do to encourage activity in a PVD patient?
- Assist with care as needed - Encourage gradual increases in activity, exercise - Provide diversional activities - Encourage frequent position changes
50
What are the two evaluations a patient would be able to demonstrate if they have PVD?
