BSN 6000 - MODULE 1 QUESTIONS WITH VERIFIED
ACCURATE ANSWERS
perfusion - Answers - flow of blood through arteries and capillaries, delivering oxygen
and nutrients to cells
central perfusion - Answers - force of blood movement generated by cardiac output
components of central perfusion - Answers - blood volume, cardiac output, blood
pressure
tissue perfusion - Answers - blood flow through body tissues and organs
components of tissue perfusion - Answers - blood vessel diameter and patency
sign of optimal perfusion - Answers - pink, warm, conscious
sign of impaired perfusion - Answers - cyanosis, altered LOC
variations of impaired perfusion - Answers - duration (acute vs chronic), type (central vs
tissue), degree (ischemia vs infarction)
ischemia - Answers - lack of blood flow
infarction - Answers - death of tissue
local consequences of impaired perfusion - Answers - hypoxic injury and cell death
systemic consequences of impaired perfusion - Answers - shock and multiple organ
failure
perfusion assessment - Answers - 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? - Answers - releases when heart muscle has been damaged
angiogram - Answers - x-ray of a vessel
electrocardiogram - Answers - record of the electrical activity of the heart
what does BUN/creatinine tell us? - Answers - kidney health
, what does cholesterol tell us? - Answers - determine risk of atherosclerosis
ejection fraction - Answers - measurement of the volume percentage of left ventricular
contents ejected with each contraction
primary management for perfusion - Answers - healthy body weight, diet, exercise, no
smoking
secondary management for perfusion - Answers - screening BP, cholesterol, genetic
test
tertiary management for perfusion - Answers - surgery = CABG, PCI, valve
replacement, pacemaker
gas exchange - Answers - process by which oxygen is transported to cells and carbon
dioxide is transported away from cells
physiological process of gas exchange - Answers - ventilation, alveolar capillary
diffusion, pulmonary perfusion, gas transport
anoxia - Answers - no gas exchange
ventilation - Answers - movement of air in and out of the lungs
pressure outside has to be... - Answers - higher than chest pressure
ventilation is controlled by... - Answers - neuromuscular control
variations of ventilation - Answers - airway obstruction, neuromuscular dysfunction, dec
compliance
alveolar capillary diffusion - Answers - surface between the alveolus and capillary
variations of alveolar capillary diffusion - Answers - dec surface area, inc diffusion
distance
pulmonary perfusion - Answers - blood flow through the pulmonary vasculature
variations of pulmonary perfusion - Answers - blood vessel narrowing/destruction, dec
central perfusion
gas transport - Answers - the process of carrying gases from the alveoli to the systemic
tissues and vice versa
variations of gas transport - Answers - dec RBC or hemoglobin
