Free EMR Cardiology, Airway, and Ventilation Test 1
Air is inhaled into the lungs when the diaphragm:
When the diaphragm contracts, it flattens and moves downward, increasing the volume of the thoracic cavity. This creates a negative pressure within the lungs, causing air to be drawn in (inhaled) to equalize the pressure.
When transporting a victim by stretcher:
When transporting a victim by stretcher you can leave the AED powered on and attached. However, the stretcher or ambulance must be completely stopped in order to get an accurate rhythm analysis.
You are checking to see if a patient is responsive when he or she lets out an agonal gasp. This is:
Agonal gasps are not regular breathing. They may be present during the first minute of cardiac arrest.
When using a simple face mask:
When using a simple face mask you should deliver air over a 1-second time period, making the chest rise.
2-rescuer CPR is performed at a ratio of what in a child?
CPR is performed at a ratio of 15 compressions to two breaths in a child with 2 rescuers.
Which of the following is considered to be an early sign of hypoxia?
An early sign of hypoxia might be disorientation and confusion. This is usually stemming from the high carbon dioxide levels in the blood.
The airway within the lungs branches into narrower and narrower passages called:
Bronchioles are the smaller branches of the airway within the lungs that branch off from the bronchi and continue to divide into smaller passages.
All of the following choices are true of an agonal gasp except:
Agonal gasps can be forceful or weak. In some cases they are forceful enough to cause head or neck movement, but not always.
If you are alone and find that a patient is not breathing and you have already activated the emergency response system you should:
If you are alone to find your patient not breathing, get an AED and then return to your patient.
When performing mouth-to-mouth breaths on an adult it is important to:
When performing mouth-to-mouth breaths on an adult it is important to take a regular breath and seal your lips around the victim’s mouth. AHA guidelines recommend against taking a deep breath.
Your partner is delivering mouth-to-mouth ventilations to a patient while you are in charge of chest compressions. Your partner is delivering quick, forceful breaths to minimize interruptions in chest compressions. Which of the following statements is true about this scenario?
Quick, forceful breaths are inappropriate and likely to end up in the patient's stomach rather than his lungs.
