Q:1What is the recommended maximum duration of time for a pulse check in any patient?
The pulse check should be performed quickly and must not exceed 10 seconds. Prolonged checking delays the start of chest compressions, which are essential for survival.
Q:2When using an Automated External Defibrillator (AED) on a child under 8 years of age, what equipment should be used?
For children under 8 years old, pediatric pads with an attenuator are used to reduce the energy delivered by the AED. This prevents delivery of an adult dose.
Q:3If a victim takes an occasional gasping, agonal breath, how should the rescuer proceed?
Agonal breaths are not effective breathing. They are a sign of cardiac arrest. The rescuer should treat this as ineffective breathing and start CPR without delay.
Q:4In single-rescuer CPR for an adult, what is the recommended ratio of compressions to breaths?
The standard ratio for single-rescuer CPR on an adult is 30 compressions followed by 2 breaths. This ensures the priority remains on high-quality compressions.
Q:5What is the recommended rate of chest compressions per minute for all age groups?
The correct compression rate for high-quality CPR is consistent for all ages and must be delivered between 100 and 120 times per minute.
Q:6If the victim is lying in a shallow puddle of water, what is the appropriate action before attempting to use the AED?
The victim must be moved to a dry area before the AED is operated. While the chest should be dry, safety for the rescuers is the highest priority.
Q:7Why does pediatric two-rescuer CPR use a higher breath ratio (15:2) than adult two-rescuer CPR (30:2)?
Pediatric cardiac arrest is primarily caused by respiratory issues (hypoxia), so more frequent ventilations (breaths) are required to correct the lack of oxygen.
Q:8When an advanced airway (such as an endotracheal tube) is correctly in place, how should ventilations be administered during continuous compressions?
With an advanced airway, compressions are continuous at 100-120 per minute. Ventilations are given independently at a rate of 1 breath every 6 seconds.
Q:9When placing AED pads on a patient with an implanted pacemaker or AICD, what is the correct action?
AED pads should not be placed directly over an implanted device. Place the pad at least one inch (2.5 cm) away to ensure the electrical current path is effective.
Q:10Which of the following is NOT a characteristic of high quality CPR?
Leaning on the chest (incomplete recoil) is a common error that reduces blood flow back to the heart, making it a characteristic of low-quality CPR.
