NUSA 401 Exam 2 With
Complete Solution
Allen test - ANSWER determining the patency of the radial and ulnar arteries
by compressing one artery site and observing return of skin color as evidence
of patency of the other artery
Aneurysm - ANSWER defect or sac formed by dilation in artery wall due to
atherosclerosis, trauma, or congenital defect
Arrhythmia - ANSWER variation from the heart's normal rhythm
Arteriosclerosis - ANSWER thickening and loss of elasticity of the arterial
walls
Atherosclerosis - ANSWER plaques of fatty deposits formed in the inner layer
(intima) of the arteries
Bradycardia - ANSWER slow heart rate, <50 beats per minute in the adult
Bruit - ANSWER blowing, swooshing sound heard through a stethoscope
when an artery is partially occluded
Cyanosis - ANSWER Dusky blue mottling of the skin and mucous membranes
due to excessive amount of reduced hemoglobin in the blood
Homans' sign - ANSWER calf pain that occurs when the foot is sharply
dorsiflexed (pushed up, toward the knee); may occur with deep vein
thrombosis, phlebitis, Achilles tendinitis, or muscle injury
Ischemia - ANSWER deficiency of arterial blood to a body part due to
, constriction or obstruction of a blood vessel
Lymphedema - ANSWER swelling of extremity due to obstructed lymph
channel, nonpitting
Lymph nodes - ANSWER small oval clumps of lymphatic tissue located at
grouped intervals along lymphatic vessels
Pitting edema - ANSWER indentation left after examiner depresses the skin
over swollen edematous tissue
Profile sign - ANSWER viewing the finger from the side to detect early
clubbing
Pulse - ANSWER pressure waves created by each heartbeat, palpable at body
sites where the artery lies close to the skin and over a bone
Pulsus alternans - ANSWER regular rhythm, but force of pulse varies with
alternating beats of large and small amplitude
Pulsus bigeminus - ANSWER irregular rhythm, every other beat is premature;
premature beats have weakened amplitude
Pulsus paradoxus - ANSWER beats have weaker amplitude with respiratory
inspiration, stronger with expiration
Systole - ANSWER the heart's pumping phase
