1. What is the primary effect of epinephrine in cardiac arrest?
|| || || || || || || || ||
A. Decreases myocardial oxygen demand
|| || ||
B. Increases coronary and cerebral perfusion pressure
|| || || || ||
C. Slows conduction through the AV node
|| || || || ||
D. Causes peripheral vasodilation
|| ||
Epinephrine increases systemic vascular resistance, which improves
|| || || || || ||
coronary and cerebral perfusion during CPR.
|| || || || || ||
2. Which rhythm is most effectively treated with defibrillation?
|| || || || || || ||
A. Asystole
B. Ventricular fibrillation ||
C. Sinus tachycardia
||
D. PEA
Ventricular fibrillation is a shockable rhythm that responds well to
|| || || || || || || || ||
defibrillation.
||
3. A 35-year-old male has a GCS of 3, snoring respirations, and no
|| || || || || || || || || || ||
gag reflex. What is the best airway intervention?
|| || || || || || || ||
,A. Nasopharyngeal airway ||
B. Oropharyngeal airway ||
C. Nasotracheal intubation ||
D. Endotracheal intubation ||
With no gag reflex and unconsciousness, definitive airway control via
|| || || || || || || || ||
endotracheal intubation is indicated.
|| || || ||
4. What is the most reliable indicator of proper ET tube placement?
|| || || || || || || || || ||
A. Bilateral chest rise || ||
B. Absence of gastric sounds|| || ||
C. End-tidal CO2 waveform || ||
D. Capnography with waveform || ||
Waveform capnography is the gold standard for confirming ET tube
|| || || || || || || || ||
placement.
||
5. Which medication is a parasympatholytic used in bradycardia?
|| || || || || || ||
A. Atropine
B. Epinephrine
C. Dopamine
D. Adenosine
Atropine blocks the parasympathetic nervous system, increasing heart
|| || || || || || ||
rate.
||
6. Which of the following best describes Beck’s triad?
|| || || || || || ||
A. Hypotension, hypertension, bradycardia || ||
B. JVD, muffled heart sounds, hypotension
|| || || ||
C. Tachypnea, wheezing, cyanosis || ||
D. Hypertension, bradycardia, irregular respirations || || ||
Beck’s triad is classic for cardiac tamponade: JVD, muffled heart sounds,
|| || || || || || || || || ||
and hypotension.
|| ||
7. What is the proper dose of adenosine for a stable adult patient
|| || || || || || || || || || ||
with SVT?
|| ||
, A. 6 mg rapid IV push
|| || || ||
B. 12 mg over 2 minutes
|| || || ||
C. 0.5 mg IV || ||
D. 1 mg IV|| ||
Adenosine is initially given as a 6 mg rapid IV push for
|| || || || || || || || || || ||
stable supraventricular tachycardia.
|| || ||
8. A patient with a sudden onset of sharp chest pain and dyspnea
|| || || || || || || || || || ||
after a long flight may have:
|| || || || || ||
A. Pneumonia
B. Pericarditis
C. Pulmonary embolism ||
D. Pneumothorax
A pulmonary embolism is likely due to prolonged immobility and
|| || || || || || || || ||
presents with pleuritic chest pain and dyspnea.
|| || || || || || ||
9. What is the pediatric dose of epinephrine 1:10,000 during
|| || || || || || || ||
cardiac arrest?
|| ||
A. 0.5 mg/kg ||
B. 0.01 mg/kg IV/IO || ||
C. 0.1 mg/kg IM || ||
D. 0.1 mL/kg ||
Epinephrine 1:10,000 is dosed at 0.01 mg/kg IV/IO in pediatric cardiac
|| || || || || || || || || ||
arrest.
||
10. What is the correct depth of chest compressions for an adult?
|| || || || || || || || || ||
A. 1 inch ||
B. 1.5 inches ||
C. At least 2 inches
|| || ||
D. 3 inches
||
High-quality CPR requires compressing the chest at least 2 inches in adults.
