TCAR - MODULE 3. THE BODY'S
RESPONSE TO INJURY EXAM WITH
100% CORRECT ANSWERS 2026
there are only two ways to drop H and H levels, what are they?
answer 1. dilute the blood with IV fluids
2. fluid compartment shift
if a patient bleeds out quickly what will their hemoglobin level be?
Low, normal, or high? answer normal!
shock is a state in which.... answer cellular metabolic oxygen
demand exceeds supply
tissue oxygenation cascade answer
when a patient is hypovolemic, one way to compensate for the
decrease in intravascular fluid is to increase water reabsorption in
the kidneys. which two processes occur to achieve this? answer
ADH release from the posterior pituitary gland to the kidneys, and
RAAS
The role of inflammation in traumatic shock is complex and
incompletely understood.
However, inflammatory mediators both hyperstimulate and
suppress immune function.
, Although inflammatory responses are present shortly after injury,
they are chiefly important in the post-resuscitative period, where
they influence SIRS and impact healing. answer
Ventilation is the initial step in the tissue oxygenation cascade.
But getting oxygen into the lungs isn't enough. It must diffuse
through the alveoli to the capillaries. Diffusion isn't helpful unless
there's adequate hemoglobin available to pick up the oxygen
once it's passed through the alveoli. And hemoglobin does no
good unless there's sufficient cardiac output to send oxygenated
red cells to where they need to go. The final step in the tissue
oxygenation cascade-and the only one that counts in the end-is
tissue oxygen utilization. Can the cells both get and use the
delivered oxygen? answer ventilation --- diffusion--- hemoglobin
availability ----- cardiac output ---- tissue oxygen utilization
pulmonary contusions can cause... answer damage to the
capillaries and alveoli which can cause issues with diffusion and
there for.... oxygenation
which parameter do we use to measure a patients ventilation
status?
saturation / SpO2
arterial oxygen / PaO2
carbon dioxide/ PaCo2, EtCO2 answer carbon dioxide
can a patient be well oxygenation without being adequately
ventilated and vice versa? answer yes
can be well oxygenated without being well ventilated- ex. patient
breathing 8 times a minute, shallow respirations. but the patient
is receiving O2 via facemask.
