Question: What is the required rate for performing chest compressions during
adult CPR? Answer: At least 100 compressions per minute. While the goal is
often cited as 100–120 bpm, maintaining a consistent pace of at least 100 is the
baseline for effective circulation. ✔️✔️
Question: What are the four universal steps for operating an Automated External
Defibrillator (AED)? Answer: Power on, attach pads, analyze the rhythm, and
deliver a shock if advised. Following these steps in order ensures the device can
correctly identify and treat life-threatening arrhythmias. ✔️✔️
Question: What is the correct frequency for providing rescue breaths to an adult
who has a pulse but is not breathing? Answer: One breath every 5 to 6 seconds.
This pace provides roughly 10–12 breaths per minute, which is sufficient to
maintain oxygenation in a non-arrested patient. ✔️✔️
Question: What is the compression-to-ventilation ratio for a single rescuer
performing adult CPR? Answer: 30:2. The rescuer provides 30 compressions
followed by 2 breaths, repeating this cycle until help arrives or an AED is ready.
✔️✔️
Question: Where should a rescuer’s hands be placed when performing chest
compressions on an adult? Answer: The center of the chest, on the lower half of
the sternum. Proper hand placement maximizes the pressure on the heart while
minimizing the risk of rib fractures or internal injury. ✔️✔️
Question: How does the ratio of compressions to ventilations change once an
advanced airway (like an ET tube or supraglottic device) is in place? Answer:
Compressions become continuous. Rescuers no longer pause compressions to
give breaths; instead, compressions are delivered at a steady rate without
interruption. ✔️✔️
Question: What is the ventilation rate during CPR after an advanced airway has
been successfully placed? Answer: One breath every 6 to 8 seconds. This
, ensures the patient receives 8–10 breaths per minute asynchronously while chest
compressions continue. ✔️✔️
Question: What is the minimum depth required for effective chest compressions
on an adult patient? Answer: At least 2 inches (5 cm). Adequate depth is
necessary to create enough intrathoracic pressure to pump blood to the brain and
other vital organs. ✔️✔️
Ventilation rate during CPR with an advanced airway. -ANSWER ✔️✔️One breath
every 6 to 8 seconds
What is the depth of compressions on adult patients. -ANSWER ✔️✔️At least 2
inches
Sudden increase in ET CO2 during CPR indicate. -ANSWER ✔️✔️ROSC
Epinephrine dose during CPR. -ANSWER ✔️✔️1 mg ratio 1 to 10,000 IV IO
First dose of adenosine. -ANSWER ✔️✔️6 mg Rapid IV push
Bradycardia with signs of poor perfusion. -ANSWER ✔️✔️Atropine, TCP,
dopamine, epinephrine
Stable SVT. -ANSWER ✔️✔️Vagal maneuvers, adenosine, then calcium channel
blocker's or beta blocker
Lateral leads -ANSWER ✔️✔️V5 and V6
