Q

What is a THROMBOEMBOLISM?

A

This is a blood clot that is floating through blood vessels until it reaches an area too narrow for it to pass, causing it to stop and block the blood flow at that point

Q

Why is it crucial to treat a heart attack quickly?

A

Once dead, the cells cannot be revived so the faster you treat the heart attack, the more cells you are able to save

19
Q

What is SYNCOPE?

A

dumbass taught you this…….FAINTING

20
Q

What are the 3 differences between an ACUTE MYOCARDIAL INFARCTION and ANGINA?

A
  1. It can occur at any time, even when a person is sleeping
  2. It does not resolve in minutes but rather 30 minutes to several hours
  3. It may or may not be relieved by rest or nitroglycerin
21
Q

What is the number 1 killer of women in the US?

A

Heart Disease

22
Q

Describe the general indicators of a patient with AMI

A

Nausea, vomiting, cold sweat, pale skin or bluish tint of skin; possible arrhythmias; low blood pressure; PAY ATTN when a patient tells you “I think I am going to die”

23
Q

What are the 3 serious consequences of AMI?

A

Sudden Death
Cardiogenic Shock
CHF

24
Q

How many patients with an AMI do not reach the hospital alive?

A

40%

25
Q

Rapid beating of the heart, 100beats/min or more is known as what?

A

TACHYCARDIA

26
Q

Unusually slow beating of the heart, 60 beats/min or less is known as what?

A

BRADYCARDIA

27
Q

Rapid heart rhythm, usually a rate of 150-200 beats/min is known as what?

A

VENTRICULAR TACHYCARDIA

28
Q

Disorganized, ineffective quivering of the ventricles causes the patient to become unconscious within seconds…this condition is known as?

A

VENTRICULAR FIBRILLATION

29
Q

What is ASYSTOLE?

A

the absence of all heart electrical activity

30
Q

What kind of shock is more commonly found after the onset of an AMI?

A

CARDIOGENIC SHOCK; heart lacks enough power to force the proper volume of blood through the circulatory system

31
Q

What usually happens between the first few hours and the first few days after a heart attack?

A

CHF Congestive Heart Failure; lungs become congested with fluid once the heart fails to pump the blood effectively

32
Q

When the right side of the heart is damaged, symptoms of DEPENDENT EDEMA is typically seen. What are the symptoms?

A

Swelling in the feet and legs

33
Q

What is a HYPERTENSIVE EMERGENCY?

A

systolic pressure greater than 160mmHg or rapid rise in systolic pressure.

34
Q

What is one of the most common signs of a hypertensive emergency?

A

a sudden severe headache

35
Q

If you suspect a patient is experiencing a hypertensive emergency…what do you do?

A

Make him or her comfortable, monitor blood pressure, position patient with head elevated, and transport rapidly to the emergency dept.

36
Q

What is an AORTIC ANEURYSM?

A

a weakness in the wall of the aorta; the aorta dilates at the weakened area, which makes it susceptible to rupture

37
Q

What is a DISSECTING ANEURYSM?

A

This occurs when the inner layers of the aorta become separated, allowing blood to flow between the layers

38
Q

What is the primary cause of dissecting aortic aneurysms?

A

uncontrolled hypertension

39
Q

What kind of patients do you use an AED on?

A

ONLY the DEAD ONES!!! jk. only to pulseless, unresponsive patients because moving patients may confuse the AED into confusing the electrical signals from the heart and the arms and chest muscles

40
Q

What are the 5 links in the chain of survival?

A
  1. Recognition of early warning signs and immediate activation of EMS
  2. Early CPR
  3. Early defibrillation
  4. Early advanced cardiac life support
  5. Integrated post arrest care
41
Q

What should you do if the AED fails while caring for a patient?

A

Report the problem to the manufacturer and the US FDA

42
Q

IF you did NOT witness the patient’s cardiac arrest, and the call to arrival interval was greater than 5 minutes, how many cycles of CPR should be performed before applying an AED?

A

5 cycles (about 2 minutes)

43
Q

Is it safe to defibrillate in a moving ambulance?

A

NO

44
Q

If traveling to the hospital with an unconscious patient, how often should you check the pulse?

A

@ least every 30 seconds
