NSG 252: Perfusion questionsfully solved & updated(graded
A+)
12-Lead EKG - answer A diagnostic test that examines the heart rhythm
from 12 separate perspectives to gain an accurate picture of the heart
function.
Echocardiogram (ECG) - answer ultrasound of the heart
echocardiography (ECHO) - answer Echoes generated by high-frequency
sound waves produce images of the heart
Lactate - answer A compound produced during the breakdown of glucose
in anaerobic metabolism and subsequently broken down by the liver. This
substance will build up when oxygenated blood supply is impaired by ANY
function.
shock - answer A condition in which the circulatory system fails to
provide sufficient circulation to enable every body part to perform its
function; also called hypoperfusion.
distributive shock - answer A condition that occurs when there is
widespread dilation of the small arterioles, small venules, or both. May
occur when heart function and the overall ablity to perfuse is otherwise
unaffected.
septic shock - answer A serious condition that occurs when an
overwhelming bacterial infection affects overall perfusion, likely by the
body's uncontrolled inflammatory response
, septic shock treatment - answer Support perfusion (-pressors, dopamine,
fluid maintainence). Treat the infection (large doses of a broad-spectrum
antibiotic).
neurogenic shock - answer Circulatory failure caused by paralysis of the
nerves that control the size of the blood vessels, leading to widespread
dilation; typically seen in patients with spinal cord injuries.
neurogenic shock treatment - answer Treatment of initial injury (may or
may not be possible), blood pressure regulation (-pressors, dopamine).
Anaphylactic shock - answer A severe allergic reaction that culminates
with the complete narrowing of the airway and the sudden, drastic drop of
blood pressure.
anaphylactic shock treatment - answer Vasodilation (epinephrine),
support airway (ambu-bag, possible vent), end allergic reaction
(diphenhydramine, H2 blockers).
obstructive shock - answer Shock that occurs when there is a block to
blood flow in the heart or great vessels, causing an insufficient blood
supply to the body's tissues.
cardiac tamponade - answer Acute compression of the heart caused by
fluid accumulation in the pericardial cavity. May be caused by MI, cardiac
rupture, or trauma.
cardiac tamponade treatment - answer Immediate pericardiocentesis
(pericardial window). Manage oxygenation.
pericardiocentesis - answer The puncture of the pericardial sac for the
purpose of removing fluid. Similar to a thoracentesis, except within the
pericardium.
tension pneumothorax - answer A trapping of air within the chest cavity
that is prevented from escaping.
