1. Which of the following is a contraindication for using
synchronized cardioversion?
A. Unstable ventricular tachycardia with a pulse
B. Stable atrial fibrillation
C. Unstable supraventricular tachycardia
D. Severe bradycardia
Answer: B) Stable atrial fibrillation
Rationale: Synchronized cardioversion is not indicated for stable
atrial fibrillation, as it can often be managed with rate control or
rhythm conversion medications.
2. In the case of a patient with a suspected hypovolemic shock,
what is the initial treatment priority?
A. Intravenous fluids
B. Synchronized cardioversion
C. Intubation
D. Defibrillation
Answer: A) Intravenous fluids
Rationale: The primary treatment for hypovolemic shock is
intravenous fluid resuscitation to restore circulating volume and
improve perfusion.
,3. When should you consider a reversible cause for a patient’s
cardiac arrest?
A. After performing CPR for 5 minutes
B. Once defibrillation has been attempted
C. After 10 minutes of resuscitation without ROSC
D. Whenever a patient shows signs of consciousness
Answer: C) After 10 minutes of resuscitation without ROSC
Rationale: Reversible causes should be considered if there is no
ROSC after 10 minutes of resuscitation, as conditions like
hypoxia, hypovolemia, and acidosis may require specific
treatments.
4. What is the most important consideration when using an
automated external defibrillator (AED) on a wet surface?
A. Dry the chest before placing the pads
B. Continue to defibrillate
C. Use a higher voltage setting
D. Use the AED on a towel
Answer: A) Dry the chest before placing the pads
Rationale: Wet surfaces increase the risk of electrical burns or
ineffective defibrillation, so the chest should be dried before
placing AED pads.
, 5. What is the target oxygen saturation (SpO2) range during
resuscitation in an adult patient?
A. 90-94%
B. 94-98%
C. 98-100%
D. 80-85%
Answer: B) 94-98%
Rationale: During resuscitation, oxygen saturation should be
maintained between 94-98% to ensure adequate oxygenation
without the risks of hyperoxia.
6. Which of the following is an indication for the use of an
intraosseous (IO) needle?
A. When intravenous access is difficult or impossible
B. When blood pressure is elevated
C. For rapid cooling in heat stroke
D. For defibrillation
Answer: A) When intravenous access is difficult or impossible
Rationale: IO access is used when IV access is difficult to obtain,
especially in cases of cardiac arrest or trauma.
