Module 6- Medical Emergencies 1 Flashcards
- There are three etiologies of shock. Explain how each of them causes the patient to fall into hypoperfusion
a. Inadequate volume
b. Inadequate pump function
c. Inadequate vessel tone.
A. Inadequate volume:
Adequate volume is needed be able to Sys. Pressure & circulate O2 to blood tissues. “Tubing” not being full enough, does not allow for blood to perfuse through adequately & reach the tissues.
(Loss of Fluid)
B. Inadequate pump function:
Heart acts as the “pump” to create enough force to pump the liquid. “Pump” failing creates shock state. (no Fluid loss just broken pump)
C. Inadequate vessel tone:
“Tone” refers to size of vessel. The to must be adequate for proper pressure to be maintained. (loss of tone)
Explain the difference between hypovolemic shock and distributive shock.
Hypovolemic shock is where there is a significant loss of blood (more then 1/5)
where is distributive shock is due to excessive vasodilation or vessel permeability to occur which causes loss in vascular tone
What happens to the pt in anaphylaxis?
a. What can we do to combat this?
- In anaphylaxis, chemical mediators that are released in a reaction cause massive and systemic vasodilation.
- chemical mediators also cause capillaries to become permeable and leak
Treatment:
administering Epinephrine: which is alpha properties that cause vasoconstriction
What can we do to combat hemorrhagic shock?
- Stop the bleeding
- Immediate transport
- Give Blood to PT to replace loss of fluid
- surgical intervention may be needed to stop the bleeding
What is the difference between compensated shock and decompensated shock?
Compensated shock is where the body is actively trying to fight against the shock and maintain BP by releasing hormones
decompensated shock is where the body is no longer able to fight against the shock and hypoperfusion
What happens to the pt as they move from decompensated shock to irreversible shock?
What are the signs of shock in adult patients?
a. Early signs?
b. Late signs?
What are the signs of shock in pediatric patients?
a. Early signs?
b. Late signs?
With shock management, how do you secure and maintain a patients airway?
For shock management, what tools can be used to establish and maintain adequate ventilation?
For shock management, What are your options here to increase the pt’s oxygen?
Why is hyperventilation in shock pt’s a bad idea?
Shock Management: why should we be aggressive with bleeding control?
Shock management, Do you splint fractures in the primary assessment or the secondary?
Why do you NOT remove impaled objects?
When would you remove an impaled object?
How does hypothermia impact your pt in shock?
During shock management we keep the patient in a supine position
Why supine?
During shock management, Why don’t we use the invert the pt anymore?
At what point in the assessment would you like to call for ALS back up?
In scene size up
How do you decide whether to wait on the scene for ALS back up or to transport and intercept with them?
Your pt has no pulse and the AED advises a shock, what rhythm are they probably in?
What are some reasons/situations that using the AED is contraindicated?
How do we separate the upper and lower airway?
Explain the difference between:
a. Respiratory Distress
b. Respiratory Failure
c. Respiratory Arrest
A. Respiratory distress:
is the first stage of respiratory issue and the characterized by bodys struggle to maintain adequate gas exchange. Body is still fighting to maintain adequate gas exchange
b. Respiratory Failure:
second stage where the bodys
C. Respiratory Distress:

c. Indications
d. Contraindications
e. Intended action
f. Side effects
For Narcan know the following:
a. Route
b. Dose
c. Indications
d. Contraindications
e. Intended action
f. Side effects
For Epinephrine know the following:
a. Route
b. Dose
c. Indications
d. Contraindications
e. Intended action
f. Side effects
What is the difference between Arteriosclerosis and Atherosclerosis?
Arteriosclerosis is a disease that cause the arteries walls to thicken.
where atherosclerosis is a type of arteriosclerosis that is due to plaque build up in the arteries.
What is the job of the Coronary arteries?
What happens when blood flow to the heart is restricted?
What happens when the heart is starved for oxygen?
What two treatments do we have for myocardial infarction?
a. What does each do?
- Percutaneous Coronary Intervention (PCI):
is a general term describing procedures used to open an obstructed artery w/o invasive surgery
- Fibrinolytic therapy:
Medications used to dissolve clots in the body
Explain the difference between an aortic aneurysm and aortic dissection.
An aortic aneurysm is a bulge in the aorta’s wall, while an aortic dissection is a tear in the inner lining of the aorta
What would you expect to find during your assessment that would lead you to believe your pt is having a AAA?
What can you do as an EMT for a AAA
Describe what is happening to your pt’s heart when they tell you they have heart failure.
Describe what is happening to your pt’s heart when they tell you they have heart failure.
What might you expect to find during your assessment in a pt that has heart failure?
know the following for Nitro:
a. Route
b. Dose
c. Indications
d. Contraindications
e. Intended action
f. Side effects
know the following for Aspirin:
a. Route
b. Dose
c. Indications
d. Contraindications
e. Intended action
f. Side effects
AMS / ALOC
What is the one thing you should check on all patients that are altered?
There are two types of Strokes ischemic and hemorrhagic. Explain the difference between the two:
Explain the difference between a stroke and a TIA.
In a TIA , unlike a stroke, the blockage is brief and there is no permanent damage
Your patient has experienced a TIA but their symptoms have resolved why should you discourage them from refusing care.
What are the components of a pre-hospital stroke scale?
