complete solution 2025/2026
perfusion - correct answer ✔flow of blood through arteries and capillaries, delivering oxygen and
nutrients to cells
central perfusion - correct answer ✔force of blood movement generated by cardiac output
components of central perfusion - correct answer ✔blood volume, cardiac output, blood pressure
tissue perfusion - correct answer ✔blood flow through body tissues and organs
components of tissue perfusion - correct answer ✔blood vessel diameter and patency
sign of optimal perfusion - correct answer ✔pink, warm, conscious
sign of impaired perfusion - correct answer ✔cyanosis, altered LOC
variations of impaired perfusion - correct answer ✔duration (acute vs chronic), type (central vs tissue),
degree (ischemia vs infarction)
ischemia - correct answer ✔lack of blood flow
infarction - correct answer ✔death of tissue
local consequences of impaired perfusion - correct answer ✔hypoxic injury and cell death
, systemic consequences of impaired perfusion - correct answer ✔shock and multiple organ failure
perfusion assessment - correct answer ✔client history, reported symptoms, VS, LOC, focused
assessment, urine output, weight gain/edema, weight loss/skin turgor, lab tests (cholesterol, troponin,
BUN/Cr, electrolytes), ECG, stress test, imaging (angiogram, electrocardiogram, ejection fraction)
what does troponin tell us? - correct answer ✔releases when heart muscle has been damaged
angiogram - correct answer ✔x-ray of a vessel
electrocardiogram - correct answer ✔record of the electrical activity of the heart
what does BUN/creatinine tell us? - correct answer ✔kidney health
what does cholesterol tell us? - correct answer ✔determine risk of atherosclerosis
ejection fraction - correct answer ✔measurement of the volume percentage of left ventricular contents
ejected with each contraction
primary management for perfusion - correct answer ✔healthy body weight, diet, exercise, no smoking
secondary management for perfusion - correct answer ✔screening BP, cholesterol, genetic test
tertiary management for perfusion - correct answer ✔surgery = CABG, PCI, valve replacement,
pacemaker
