NR304 Final Exam Combined With NR302 – Questions
Answered With Expert Insight
How do arteries pump blood? Correct Answer - during the recoil of the
vessel this propels the blood forward
Where would you feel for the temporal artery? Correct Answer - in front
of the ear
Where would you feel for the carotid artery? Correct Answer - groove
between the sternomastoid muscle and the trachea
What is the major artery supplying the arm ? Correct Answer - the
brachial
Where does the brachial artery run from? Correct Answer - runs in the
biceps and triceps furrow of the upper arm and surfaces at the antecubital
fossa in the elbow medial to the biceps tendon.
What the brachial artery bifurcate into? Correct Answer - ulnar and
radial arteries
What do the ulnar and radial arteries make up? Correct Answer -
superficial and deep palmer arches
Major artery of the leg? Correct Answer - femoral artery
Femoral artery travels down thigh posterior to make what artery? Correct
Answer - popliteal artery
Below the knee the popliteal artery divides into what? Correct Answer -
anterior tibial artery which travels down the front of the leg on the dorsum of
the foot where it becomes the dorsalis pedis
In the back of the leg the posterior tibial travels down the medial malleolus
and forms the plantar arteries in the foot
,Ischemia Correct Answer - deficient supply of oxygenated arterial blood
to a tissue caused by obstruction of a blood vessel
Peripheral artery disease
define
Causes Correct Answer - affects noncoronary arteries and usually refers
to arteries supplying the limbs.
Usually caused by atherosclerosis and less commonly by embolism,
hypercoagulable states and arterial dissection
Veins absorbs what? Correct Answer - co2 and waste and bring it back
to the heart to clean up
each arm has two sets of veins ? Correct Answer - 1. superficial: are in
the subcutaneous tissue and in charge of most of venous return
2. deep
Legs have three types of veins:
three types and examples? Correct Answer - 1. deep veins- conduct most
of venous return. example femoral and popliteal veins
2. superficial veins- are the great and small saphenous
3. perforators- connecting veins that joins the two sets of veins. they form a
one way valve that routes blood from superficial into deep veins
Great saphenous vein Correct Answer - longest vein in body;
drains blood from foot, leg, and thigh;
joins with femoral vein
Small saphenous vein Correct Answer - empties into the popliteal vein
How does venous flow work- three ways? Correct Answer - 1.
contracting skeletal muscles
,2. pressure gradient caused by breathing in which inspiration makes the
thoracic pressure decrease and the abdominal pressure increase
3. intraluminal valves which ensures unidiectional flow
in the legs what is the calf pump or peripheral heart? Correct Answer -
when you walk your calfs contract and relax causes the blood to flow back up
through the veins.
during contraction the gastrocnemius and soleus muscles squeeze the veins
and direct the blood flow proxmially
capacitance veins Correct Answer - high capacitance due to the bigger
diameter and ability to stretch more
efficient venous return depends on what three things? Correct Answer -
contracting skeletal muscles
competent valves in veins
patent lumen
people at risk for venous disease are people who what? Correct Answer -
prolonged standing, sitting or bed bond because they are milking or pumping
their blood
problem with the lumen called? Correct Answer - incompetent valves
where the lumen is so wide that the valve cusps cannot contain all the blood.
this would increase venous pressure
lymphatic system does what Correct Answer - retrieves excess fluid and
plasma protein from the interstitial spaces and returns them to the blood
stream
how does fluid move form the lymph system to the blood stream- what
gradient? Correct Answer - pressure gradient "filtration"
, most plasma protein are to big to be pushed out of the arterioles and remain
in the them this causes what? Correct Answer - colloid osmotic pressure
that pulls interstitial fluid back into the venules
colloid osmotic pressure (COP) Correct Answer - contribution of protein
to blood osmotic pressure
the lymph vessels drain into two main trunks Correct Answer - right
lymphatic duct- which empties into the right subcalvian veins. drains the right
side of the head, neck, right arm, right side of thorax, right lungs and pleura,
right side of heart and right upper section of liver
thoracic duct- drain the rest of the body it then empties into the left
subclavian veins
lymphatic system functions 3 ways? Correct Answer - conserve fluids
and plasma proteins that leak out of capillaries
forms a major part of immune system
absorb lipids from small intestines
cervical nodes drain what Correct Answer - the head and neck
axially nodes drain what Correct Answer - breast and upper arms
Epitrochlear nodes drain Correct Answer - antecubital fossa and drains
the hand and lower arm
inguinal node drains Correct Answer - most of the lymph of the lower
extremity, external genitalia and anterior abdominal walls
spleen:
location?
4 functions? Correct Answer - LUQ
1. destroy old RBC
