Q

Why is a biphasic defibrillator more commonly used than a monophasic one?

A
  • they are equally as effective

- biphasic has less risk of burn and decreased energy use

Q

T/F: It is safe to cardiovert a pregnant patient or a patient with a pacemaker/ICD.

A

True

22
Q

What are the 3 primary examples of SVT?

A
  • AVNRT
  • AVRT
  • Atrial tachycardia
23
Q

What is the easiest way to differentiate ST and SVT?

A
  • ST = HR < 140

- SVT = HR > 140

24
Q

What is the appropriate management for a hemodynamically STABLE SVT? (4 lines of treatment)

A
  1. vagal maneuvers
  2. adenosine 6 mg IV
    2a. repeat adenosine 12 mg IV
  3. B-blocker or CCB
  4. cardioversion
25
Q

What is the treatment for a hemodynamically unstable SVT?

A

cardioversion

26
Q

What is the best vagal maneuver to use for a SVT?

A

modified valsalva

27
Q

“U” wave on ECG is pathognomonic for what abnormality?

A

hypokalemia

28
Q

“J” wave on ECG is pathognomonic for what abnormamility?

A

hypothermia

29
Q

What are the Hs and Ts of pulseless electrical activity (PEA)?

A

Hs

  • hypoxia
  • hypovolemia
  • hypo/hyperkalemia
  • hypothermia
  • hydrogen ion (acidosis)

Ts

  • thrombosis
  • thromboembolism (PE)
  • tension pneumothorax
  • tamponade
  • toxins/tablets
30
Q

What is the best treatment for hyperkalemia?

A

give calcium!

31
Q

What is the most common maneuver to assess the airway?

What maneuver is used in the instance of a C-spine injury?

A
  • most common = head tilt/chin lift

- c-spine injury = jaw thrust

32
Q

What are airway adjuncts (such as oropharyngeal airway or nasopharyngeal airway) used for?

A

remove the tongue which is the main cause of airway obstruction

33
Q

What are the 3 indications for tracheal intubation?

A
  • failure to oxygenate or failure to ventilate
  • unable to protect the airway
  • predicted clinical course
34
Q

What are the 7 P’s of rapid sequence intubation (RSI)?

A
  • Preparation
  • Preoxygenation
  • Pre-intubation optimization
  • Paralysis
  • Positioning
  • Placement with proof
  • Post intubation management
35
Q

Why is preoxygenation important in RSI?

How is it done?

A
  • increases time to desaturation by minutes

- high flow O2 at the highest possible concentration for 3 minutes

36
Q

What is the most hemodynamically stable induction agent (sedative) for RSI?

A
  • etomidate

propofol - decreases BP
ketamine - increases BP

37
Q

What is the most rapid paralytic agent we have for RSI?

When is it contraindicated?

A
  • succinylcholine (onset 30-45s)

- contraindicated = hyperkalemia

38
Q

What is the main reason we need to rapidly paralyze a patient vs. a more slow progression seen in surgery?

A

decrease risk of aspiration d/t patient not being on NPO

39
Q

What is the best way to confirm ETT placement?

A
  • capnography

wave > color

40
Q

What are the 3 main causes of respiratory arrest?

A
  • airway obstruction from choking
  • decreased respiratory effort from opiates
  • respiratory muscle weakness
41
Q

What are the 2 methods to monitor breathing?

A
  • O2 saturation

- waveform capnography

42
Q

This is used to assist patients with inadequate or absent respirations while awaiting advanced airway or further management (if reversible cause).

A

bag valve mask

43
Q

What is goal O2 sat?

A

> 94%

44
Q

After performing ABCs what should be assessed next?

A

vital signs!

45
Q

Where can you place intraosseous (IO) access?

a. proximal tibia
b. femur
c. proximal humerus
d. manubrium
e. all of the above

A

e. all of the above

46
Q

Once you obtain IO access how long do you have before you need to remove the access point?

What is the main risk with IO access?

A
  • need to remove in 24 hours

- high risk for osteomyelitis

47
Q

A 50-year-old male with a history of ESRD is brought to the emergency department by BLS after being found unresponsive. He has no pulses and is not breathing. CPR is in progress. Rescue breaths are being administered via BVM. The cardiac monitor shows sinus tachycardia. What is the next best step?

A. Defibrillate
B. Establish advanced airway
C. Place IV for blood transfusion
D. Cardioversion 
E. Cease resuscitation efforts
A

B. Establish advanced airway

48
Q

The patient is successfully intubated with an endotracheal tube. The CO2 detector changes from purple to yellow and the waveform reveals CO2 of 35-45. The patient remains pulseless, and CPR is in progress. The cardiac monitor continues to show sinus tachycardia. What is next?

A. Portable chest x-ray to confirm ETT placement
B. Explore reversible causes (Hs and Ts)
C. Cease resuscitation efforts
D. Defibrillate
E. Remove ETT given esophageal intubation

A

B. Explore reversible causes (Hs and Ts)

49
Q

You begin exploring Hs and Ts and EMS informs you that the patient missed dialysis yesterday. What is the best medication to order?

A. Oxygen
B. Sodium bicarbonate
C. Magnesium
D. Calcium
E. Potassium
A

D. Calcium

50
Q

A nurse grabs you to see a 45-year-old male in the waiting room is not responding. You walk into the room and patient is seated in a chair with his eyes closed and is not moving. What is the first thing you should do?

A

check responsiveness!

51
Q

A nurse grabs you to see a 45-year-old male in the waiting room. You check responsiveness and the patient is not responding to verbal or painful stimuli. You assess CABs:
C: Weak pulse

B: RR 6, O2 sat 88%/RA

What is the next best step?

A. Start CPR
B. BVM and supplemental oxygen 
C. Explore Hs and Ts
D. Intubate
E. Cardiovert
