Free EMR Cardiology, Airway, and Ventilation Test 3
A rescuer’s exhaled air contains approximately:
Exhaled air contains approximately 17% oxygen.
Proper technique when performing the head tilt chin lift includes:
When performing the head tilt chin lift, the rescuer should place 2 or 3 fingers under the bony part of the chin and lift the jaw while bringing the chin forward.
If breathing is inadequate or absent providing rescue breathing can:
Providing rescue breathing can prevent a patient from going into cardiac arrest.
You witnessed a patient become unresponsive after choking. The correct order of procedures is to:
If a choking patient becomes unresponsive start chest compressions, open the victim’s mouth, look for an occluding object, then remove it with your fingers. A bite stick should not be used as it is likely to just push the object in further.
The respiratory system functions by:
The primary function of the respiratory system is to exchange gases: bringing oxygen (O2) into the body and removing carbon dioxide (CO2). Option A best describes the main function of the respiratory system, which is crucial in the context of cardiac and respiratory emergencies covered under Cardiology and Resuscitation in EMR training.
Which of the following pieces of equipment should be included in the EMR's life support kit?
EMRs are typically trained to manage basic airway and ventilation needs. A mouth-to-mask ventilation device is essential in providing basic respiratory support by delivering oxygen to a patient who is not breathing adequately. This device allows the EMR to maintain oxygenation until more advanced airway management can be provided by higher-level medical personnel.
While functioning at the scene of a patient in cardiac arrest, you do not initiate CPR because the patient is elderly and you think that he is probably dead. Paramedics arrive and determine that the patient has only been in cardiac arrest for 6 minutes. Which of the following statements regarding this scenario is correct?
As an Emergency Medical Responder (EMR), you are trained to initiate CPR in cases of cardiac arrest regardless of age or initial assessment of the patient's condition. The statement in option A highlights the legal and ethical obligation of healthcare providers to follow established standards of care, which include initiating CPR upon encountering a patient in cardiac arrest.
When opening the airway of an unconscious injured patient, you should:
The jaw-thrust maneuver is the recommended method to open the airway of an unconscious injured patient, especially when trauma to the neck or spine is suspected.
If you are unable to feel a carotid pulse in an unconscious, non-breathing adult within 5 to 10 seconds, you should:
If you are unable to feel a carotid pulse in an unconscious, non-breathing adult within 5 to 10 seconds, it indicates a need for immediate CPR (Cardiopulmonary Resuscitation).
The principle of implied consent assumes that an unconscious patient:
The principle of implied consent applies in emergency situations where a patient is unconscious or otherwise unable to give explicit consent for treatment. Implied consent assumes that a reasonable person, if conscious and able to do so, would consent to receive necessary medical treatment. Option D reflects this understanding, as it aligns with the ethical and legal framework of providing emergency medical care to unconscious patients based on the assumption that they would want treatment if they were able to express their wishes.
After opening the airway of an unconscious elderly woman, you discover that there are thin secretions in her mouth. You should:
Upon discovering thin secretions in the mouth of an unconscious elderly woman, the appropriate action is to clear the airway using suction to remove any obstructions or secretions.
