Flashcards in Practice questions Deck (77)
What are the 4 cardiac arrest rhythms?
1. Ventricular Fibrillation
2. Ventricular Tachycardia
4. Pulseless electrical activity
What are the shockable cardiac arrest rhythms?
Ventricular fibrillation and ventricular tachycardia
How do you determine the size of the airway?
From the corner of the mouth to the tip of the earlobe or the angle of the jaw
When do you use atropine?
To treat symptomatic bradycardia
WHat's the appropriate intervention for acute coronary syndrome?
MONA - morphine, oxygen (if indicated - cyanotic, oxygen saturation less than 94%), nitroglycerin, aspirin
IV access should also be made
What's the correct ratio of compressions to ventilations in adult CPR?
What is the typical dose given by the tracheal route?
2 - 2.5 times the recommended IV dose
Dilute the recommended dose in 5-10 ml of sterile water or normal saline and administer
What drugs can be absorbed via the trachea?
Naloxone, atropine, vasopressin, epinephrine and lidocaine
What are the first line antiarrhythmics for a stable wide QRS tachycardia that is most likely VT?
Procainamide, amiodarone, sotalol
What drugs would be used in the management of narrow QRS tachycardias?
Adenosine, diltiazem, and verapamil
What drug can be used in diagnosis when the origin of a wide-QRS tachycardia is unclear?
What drugs can be used in the management of symptomatic bradycardias?
Atropine and isoproterenol
What is the first antiarrhythmic administered in the management of a patient in pulseless VT or VF?
- you can use lidocaine if amiodarone is unavailable
What is a common cause of excessive intrathoracic pressure during CPR?
when is supplemental oxygen therapy indicated?
if the patient is hypoxic, cyanotic, having difficulty breathing, has obvious signs of heart failure or shock, or if her O2 saturation declines to less than 94%
If breath sounds are absent on both sides of the chest after placing a trachea tube, what should you assume?
If breath sounds are diminished on the left after intubation but present on the right, what should you assume?
Right primary bronchus intubation
What might you see if a mucus plug presents in the tracheal tube?
increased resistance during positive pressure ventilation
What drugs can improve perfusion pressures during cardiac arrest?
Vasopressors like epinephrine to constrict blood vessels
What acronym is used to quickly assess a patients level of responsiveness (used in primary survey)?
responds to VERBAL stimuli
responds to PAINFUL stimuli
What acronym is used for the primary survey in a responsive patient?
What is done in a primary survey of an unresponsive patient?
What rhythms do you use defibrillation for?
Sustained polymorphic VT
What rhythms do you use synchronized cardioversion?
Unstable narrow-QRS tachycardia
Unstable atrial flutter
Unstable atrial fibrillation
Unstable monomorphic VT
What rhythms do you use transcutaneous pacing for?
In acute stroke management, what phrase reflects the need for rapid assessment and intervention?
Time is brain
delays in DX and TX can leave the patient neurologically impaired and disabled
what is the most reliable method for confirmation and monitoring of tracheal tube placement?
Clinical assessment and continuous quantitative waveform capnography
What can be used to replace either the first or second dose of epinephrine in the TX of pulseless arrest?
One dose of Vasopressin 40 U IV/IO bolus
when are the incidence of dysrhythmias the highest after the onset of symptoms after a STEMI?
Highest during the first 4 hrs after onset of symptoms and remains an important contributing factor to death in the first 24 hrs after a STEMI
