NR 304 EXAM 2 ALL QUESTIONS
WITH CORRECT ANSWERS
What is deep vein thrombosis and what is it caused by?
A clot forming in a deep vein of the extremity (usually one one extremity).
Usually caused by thickened blood or venous stasis.
What is a pulmonary embolism?
When a DVT moves into the lungs.
What is occurring when the finger nails club?
Hypoxia and/or COPD.
What is the modified Allen test?
Used to evaluate circulation.
Occlude both the ulnar and radial arteries of one hand while the pt makes a fist. The
skin will blanche, have the pt open their hand and then release the arteries.
With normal circulation, the hand should return to normal color within 3-5 seconds
What do the arteries do?
Transport oxygenated blood (along with oxygen and nutrients) away from the heart
and to the bodies.
What is ischemia?
Deficient supply of blood resulting in tissue death.
This is because of a complete blockage of an artery.
How are you able to tell if any artery is patent?
By feeling pulses.
Usually a distal artery is best for this because it is farther away from the heart.
For example, the radial pulse of the UE or the dorsalis pedis of the LE.
What do the veins do?
Carry deoxygenated blood (along with CO2 and waste) back to the heart.
What three things determine efficient venous return?
, Contracting skeletal muscles.
Competent valves in the veins.
Patent lumen
What are the two types of veins?
Superficial and deep veins.
What does the lymphatic system do?
Vacuums fluid and plasma proteins from the interstitial space back to the
bloodstream.
Defends the body from disease.
Also play a part in lipids.
How should you palpate lymph nodes?
Apply a gentle pressure and feel in a circular motion.
What does peripheral vascular disease refer to?
An umbrella term referring to issues regarding the veins and arteries.
What is peripheral arterial disease?
The blood, oxygen, and nutrients cannot get to the extremities.
This usually happens in people who are older and have high cholesterol.
Can be cause by rigidity or the arteries or a build up of plaque.
What is peripheral venous disease?
The blood, oxygen, and nutrients cannot get back up to the heart and pools in the
extremities.
What are r/f for peripheral venous disease?
Smoking
Obesity
Hypertension
Diabetes
High cholesterol/diet
Stress
Genetics
Advanced age
Organ failure
Injuries
.
