NURS 247- Exam 3 Questions and Correct Answers Latest Update 2025 (Graded A+)
what are arteries - Answers carry oxygenated blood to body, elastic, high pressure, lots of muscle
surrounding them, make up pulses
What are the 9 pulse locations? - Answers radial, ulnar, brachial, temporal, carotid, femoral, popliteal,
posterior tibial, dorsalis pedis
what are veins - Answers carry deoxygenated blood back to heart, capacitance vessels, lower pressure,
thinner than artery, contraction of muscles and gravity allow it to go back to heart
what are lymphatics and 3 main locations - Answers conserves fluid and plasma, part of the immune
systems, cervical, axillary, and inguinal
-should not be able to palpate them
what are some organs that are apart of the lymphatic system - Answers spleen = destroys RBCs and
filters blood
Peyer's patch = intestines
tonsils
thymus = produces T cells
what is some subjective data for perfusion - Answers claudication (leg pain when walking), pallor,
swelling, smoking history, birth control, hemosiderin staining (brown stains from stationary RBCs that
have leaked iron)
what is some objective data to gather about perfusion - Answers symmetry, color, temperature, venous
pattern, nail bed color, asymmetrical swelling, thin shiny skin (lack of perfusion)
what are some things to palpate - Answers temperature, pulses, cap refill, edema, lymph nodes, allen
test, homan's sign
what is allen test and homan's sign - Answers allen test = tells if both radial and ulnar are working
homan's sign = indicator of a DVT, push toes toward body and note any tenderness
why might a measurement of the calf be helpful - Answers check calf circumference and compare to
other side, sign of DVT is unilateral swelling
What is the ankle-brachial index and what does it tell you? - Answers Measures difference between
ankle and brachial systolic pressures, can tell if pt has PAD
what is lymphdema - Answers lymph blockage and back up in extremities, usually from removing nodes
during a mastectomy
, What is Raynaud's phenomenon? - Answers arterial spasm, numbness, pain, throbbing, brought on by
stress or cold
what is an aneruysm? - Answers dilation of an artery due to a weakened vessel
-can rupture and cause a hemorrhage
What is an ischemia? - Answers reduced blood flow which can cause a lack of oxygen
What is varicose veins? - Answers enlarged veins, valve issues, reports of heavy legs, fatigue
what can cause a DVT and how to prevent it - Answers venous stasis (prolonged bed rest), trauma, heart
failure, cancer
-being active
what is venous disease and how to prevent it - Answers - warm and red (excess blood)
- browning staining (iron leaked from blood)
- firm skin
- edema (fluid buildup)
- pulse
- ulcer: irreg shape, wet, weeping
prevent: compression stockings
what is PAD and how to prevent it - Answers - cool pale skin (no blood flow)
- thin, frail skin (bad perfusion)
- no edema
- weak pulse
- ulcer: perfectly round, dry
- can lead to DVT
Prevent: being active
what does aging do to vessels - Answers rigid, weakened, trophic changes (thickened nails, loss of
extremity hair)
what is the anatomy of the abdomen - Answers supported by 4 muscles layers, contains organs including
the kidneys, has 4 quadrants
