BLS Algorithm Flashcard 5
Rationale
B. Rationale: For the single-rescuer approach in CPR, the recommended compression-to-ventilation ratio is 30:2.
Question
You are performing single-rescuer CPR to a patient with out-of-hospital cardiac arrest secondary to acute myocardial infarction. What is the chest compression-to-ventilation ratio in CPR for this case?
a. 2:1
b. 30:2
c. 10:1
d. 12:2
Answer
b. 30:2
Rationale
C. Rationale: It is critical to minimize interruptions in the delivery of chest compressions. At this time, it is important to resume CPR, and bag-mask ventilation can suffice until the insertion of an advanced airway is feasible.
Question
You are the ACLS team leader whose team is attempting to revive a 64-year-old man with cardiac arrest. Your airway team member has tried twice to insert the endotracheal tube to no avail. What should you do in this situation?
a. Look for an expert to insert the endotracheal tube
b. Attempt to insert the endotracheal tube yourself
c. Continue to perform high-quality CPR and ventilate via bag-mask
d. Assess for pulse and spontaneous breathing
Answer
c. Continue to perform high-quality CPR and ventilate via bag-mask
Rationale
C. Rationale: Waveform capnography can measure CPR quality and confirm ET tube placement.
Question
Your team is resuscitating a patient with pulseless electrical activity secondary to hypoxia from carbon monoxide poisoning. It is imperative that intubation is successful to adequately ventilate the patient, reverse the hypoxia, and achieve return of spontaneous circulation. After inserting an endotracheal tube (ET tube), what is the best indicator that confirms the ET tube placement and gives out vital metrics on the condition of the patient?
a. Auscultation for gas bubbles
b. Chest X-ray
c. Waveform capnography
d. Oxygen saturation
Answer
c. Waveform capnography
Rationale
B. Rationale: The chest compression rate must be between 100 and 120 per minute. These rates have been associated with improved survival in patients with cardiac arrest.
Question
Your team leader wants you to increase the chest compression rate while performing high-quality CPR. What is the recommended chest compression rate for a patient with cardiac arrest?
a. 60–90 compressions per minute
b. 100–120 compressions per minute
c. 90–100 compressions per minute
d. 80–90 compressions per minute
Answer
b. 100–120 compressions per minute
