Question 1:
What is the recommended initial dose of epinephrine for a patient in cardiac arrest?
A) 0.5 mg IV/IO every 5 minutes
B) 1 mg IV/IO every 3-5 minutes
C) 2 mg IV/IO every 10 minutes
D) 1 mg IV/IO every 10 minutes
Answer: B) 1 mg IV/IO every 3-5 minutes
Rationale: Epinephrine is administered to help increase coronary perfusion pressure. The
recommended dose for adults in cardiac arrest is 1 mg IV/IO every 3-5 minutes during
resuscitation. This timing helps optimize the effectiveness of the medication and improve the
chances of return of spontaneous circulation (ROSC).
Question 2:
In which of the following situations would you use an automated external defibrillator
(AED)?
A) Asystole with no pulse
B) Pulseless ventricular tachycardia (VT) or ventricular fibrillation (VF)
C) Symptomatic bradycardia with a pulse
D) Atrial fibrillation with a pulse
, Answer: B) Pulseless ventricular tachycardia (VT) or ventricular fibrillation (VF)
Rationale: An AED is used to deliver a shock to the heart in cases of pulseless VT or VF. It is
not indicated for asystole or bradycardia with a pulse. The AED helps restore a normal rhythm
by delivering a controlled electrical shock to the heart.
Question 3:
What is the recommended chest compression rate for adults during CPR?
A) 60-80 compressions per minute
B) 80-100 compressions per minute
C) 100-120 compressions per minute
D) 120-140 compressions per minute
Answer: C) 100-120 compressions per minute
Rationale: The recommended chest compression rate during CPR is 100-120 compressions
per minute. This rate helps to effectively circulate blood to vital organs and improve the
likelihood of successful resuscitation. Compressions that are too slow or too fast may reduce
the effectiveness of CPR.
Question 4:
What is the primary goal of chest compressions during CPR?
A) To provide oxygen to the lungs
B) To maintain blood circulation to vital organs
C) To normalize blood glucose levels
D) To assess the patient’s responsiveness
Answer: B) To maintain blood circulation to vital organs
Rationale: The primary goal of chest compressions during CPR is to maintain blood circulation
to the brain and other vital organs. Effective chest compressions help to ensure that oxygenated
blood continues to flow to critical areas while other interventions are administered.
Question 5:
For a patient with symptomatic bradycardia, if atropine is ineffective, what should be the
next step?
A) Administer intravenous fluids
B) Initiate synchronized cardioversion
