Perfusion
Ischemia - correct answer-An inadequate blood supply to an organ or part of
the body, esp. the heart muscles.
(blood supply is available but decreased.)
Infarction - correct answer--Area of dead tissue (necrosis) caused by
decreased blood flow to that part of the body.
-(Myocardial infarction aka heart attack: death of myocardial tissue with an
inability to regenerate.)
-A heart attack occurs when blood flow to a part of your heart is blocked for a
long enough time that part of the heart muscle is damaged or dies. The
medical term for this is myocardial infarction.
Anoxia - correct answer-ABSENCE OR LACK OF OXYGEN.
(an abnormally low amount of oxygen in the body tissues.)
Arteriosclerosis - correct answer-Thickening and hardening of the arteries.
Atherosclerosis - correct answer-Fatty build up and plaque in the arteries.
Perfusion - correct answer-The flow of blood through arteries and capillaries
delivering nutrients and oxygen to cells and removing cellular wastes.
Evidence of optimal central perfusion - correct answer--HR and BP are within
normal limits.
-Patients orientation to time, place, person and situation is normal.
-Normal bilateral movement and sensation.
-Clear speech.
-Presence of carotid pulse ad absence of carotid bruit.
Presence of optimal peripheral tissue perfusion - correct answer--Patients
extremities are warm with color appropriate for race.
, -Capillary refill time is less than 2 seconds.
-Patients report warm hands and feet and absence of pain in fingers and toes
or legs when walking.
Perfusion is dependent on: - correct answer--Blood volume.
-vascular resistance.
-cardiac output.
Dusky - correct answer-Blue grey pale color starting around lips and moving
outward. (Example in infants.)
Primary prevention - correct answer-Measures to promote health and prevent
development of disease.
Examples: smoking and nicotine cessation, diet, exercise, weight control.
Secondary prevention - correct answer-Screening and early diagnoses and
prompt treatment of existing health problems.
Examples: BP screening, lipid screening.
SA node (sinoatrial node) - correct answer--Hearts natural pacemaker.
-Perfusion begins when the heart is stimulated by an electrical impiulse that
originates in the SA node.
Antecedents for perfusion - correct answer--Functioning cardio-pulmonary
system.
-Adequate fluid volume.
-Free from clots and atherosclerotic blocks.
Attributes for perfusion - correct answer--Blood pressure within normal limits.
-Capillary refill that is less than 2 seconds.
