EMORY DPT GMC: Nutrition and Wound
Management (Etiologies) EXAM | Comprehensive
Questions and Answers | A+ Graded | With Expert
Solutions
What is the Rubor of Dependency?
With the foot dangling, (length of time is not an issue) observe the
bottom of the foot. If it is a red color, as if the foot is "blushing", they may
arterial deficiencies.
Etiology - as the blood is attempting to travel down the artery it meets
the occlusion and is shunted out into the tissues giving that red or
"blushing" color.
How is Venous Filling Time related to a wound?
Begin with the patient in supine. Inspect the foot for veins that are raised.
Raise the same leg in question above the level of the heart until the vein
is drained and no longer raised. Put the leg down by sitting the patient
up and dangling the leg below the heart. Observe the top of the foot
and time in seconds how long it takes for the vein to begin to raise
above the skin. Should be less than 20 seconds. If greater than 20
seconds there are likely arterial occlusions.
,What is Capillary Refill?
True test you press on the great toe nail bed until it blanches (becomes
white). Release and time (in seconds) how long it takes for the bed to
become pink. Should be less than 3 seconds.
If the nail bed is discolored and unable to see through press on the tip
of the toe.
What are the three major causes of venous wounds?
Incompetent valves in the vein
Obstruction - Deep Vein Thrombosis, Pregnancy, Obesity
Calf muscle pump failure
, What are the two types of venous wound characteristics?
In Venous Insufficiency you can have an excessive what?
dry skin
What is a chronic venous insufficiency?
Impaired return of venous blood from the tissues to the heart.
Accounted for 70% to 90% of all leg ulcers.
Venous system consists of deep veins, superficial veins and perforator
veins (connect the superficial and deep veins).
Return of the blood depends on intact one way valves, smooth muscle
tone of the venous walls and contraction of the gastrocnemius and
soleus muscles.
Loss of valve competency allows back flow of blood into the vein and
changes a one direction system into a bidirectional system.
