    The jaw-thrust maneuver is for patients who have cervical spine injuries.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The jaw-thrust maneuver is a technique used to open the airway in patients who have potential or confirmed cervical spine injuries. This maneuver is preferred over the head-tilt/chin-lift technique because it minimizes movement of the neck and reduces the risk of further injury to the cervical spine. By displacing the jaw forward without flexing the neck, the airway can be opened and maintained while ensuring the stability of the cervical spine. Therefore, the statement is true.

    The primary function of the airway adjuct is to prevent obstruction of the upper airway by the tongue and allow the passage of air and oxygen to the lungs.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The primary function of an airway adjunct is to prevent obstruction of the upper airway by the tongue and allow the passage of air and oxygen to the lungs. This statement is true because airway adjuncts such as oropharyngeal airways and nasopharyngeal airways are designed to keep the tongue from blocking the airway and maintain an open pathway for air to flow into the lungs. These devices are commonly used in emergency medical situations to ensure adequate oxygenation and ventilation.

    Maintaing the airway means what?

    • Keeping airway open

    • Keeping airway clear

    • Keeping free of obstructions

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Maintaining the airway refers to the process of ensuring that the airway remains unobstructed and open, allowing for proper breathing. This includes keeping the airway clear of any obstructions, such as mucus or foreign objects, and ensuring that it remains open to allow for the passage of air. Therefore, the correct answer is "All of the above" as it encompasses all the actions required to maintain the airway.

    Gastric distention can cause vomiting and increase risk of aspiration during CPR.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Gastric distention refers to the abnormal accumulation of air or fluid in the stomach. During CPR (cardiopulmonary resuscitation), the chest compressions can cause the stomach to inflate, leading to gastric distention. This can be problematic as the inflated stomach can put pressure on the diaphragm, making it difficult for the person to breathe properly. Additionally, if the person vomits during CPR, there is a higher risk of the vomit being aspirated into the lungs, which can lead to further complications. Therefore, gastric distention can indeed cause vomiting and increase the risk of aspiration during CPR.

    Rate this question:

  • 7. 

    Gastric distention can significantly reduce lung volume by elevating the diaphragm especially in children and infants.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Gastric distention refers to the condition where the stomach becomes excessively filled with air or gas. When this happens, it can cause the diaphragm, which is the muscle responsible for breathing, to be pushed upward. This elevation of the diaphragm can lead to a reduction in lung volume, particularly in children and infants. Therefore, it is true that gastric distention can significantly reduce lung volume by elevating the diaphragm.

    Clearing the airways means what?

    • Removing obstructing materials

    • Inserting an oral adjunct

    • Placing patient in recovery position

    • Applying a BVM device

    Correct Answer
    A. Removing obstructing materials
    Explanation
    Clearing the airways means removing any materials that may be obstructing the passage of air in the respiratory system. This can include clearing mucus, foreign objects, or any other obstructions that may be preventing proper airflow. By removing these obstructing materials, the airways can be opened up and the patient can breathe more easily.

    If a tracheostomy tube is present in a stoma patient then ventilate throught the tube with a BVM device.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    If a tracheostomy tube is present in a stoma patient, it means that there is an opening in the neck leading directly to the trachea. Ventilating through the tracheostomy tube with a BVM (bag-valve-mask) device allows for the delivery of oxygen directly to the patient's lungs. This method ensures that the airway is bypassed and that oxygen is reaching the lungs effectively. Therefore, the statement is true.

  • 12. 

    Patients with inadequate breathing have inadequate minute volume and need to be treated immediately.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Patients with inadequate breathing have inadequate minute volume, which refers to the amount of air that is inhaled and exhaled in one minute. When the minute volume is inadequate, it means that the patient is not getting enough oxygen and is not effectively removing carbon dioxide from their body. This can lead to serious health complications and can be life-threatening. Therefore, it is crucial to treat patients with inadequate breathing immediately to ensure that they receive the necessary support and intervention to improve their breathing and maintain proper oxygenation.

  • 14. 

    The higher the level of carbon dioxide in the blood the stronger the impulse is to breath.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    When the level of carbon dioxide in the blood increases, it triggers chemoreceptors in the brain to send signals to the respiratory muscles, increasing the impulse to breathe. This is because high levels of carbon dioxide indicate a need for more oxygen in the body. Therefore, the statement is true.

  • 17. 

    Sellick maneuver or Cricoid pressure should only be preformed on unconscious patients.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The Sellick maneuver or Cricoid pressure is a technique used during intubation to prevent aspiration of stomach contents into the lungs. It involves applying pressure on the cricoid cartilage to occlude the esophagus. This maneuver should only be performed on unconscious patients because conscious patients may experience discomfort or difficulty in swallowing. Additionally, conscious patients can actively resist the pressure, making the maneuver ineffective. Therefore, it is important to ensure that the patient is unconscious before performing the Sellick maneuver.

    Rate this question:

  • 18. 

    Exhalation does not normally require muscular effort and is a passive process.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Exhalation is the process of expelling air from the lungs. During exhalation, the diaphragm and intercostal muscles relax, allowing the lungs to passively recoil and push air out. This means that exhalation does not require any muscular effort and is a passive process. Therefore, the statement that exhalation does not normally require muscular effort and is a passive process is true.

    Rate this question:

  • 19. 

    In unconscious patients what is the most common airway obstruction?

    Correct Answer
    the tongue
    tongue
    Explanation
    In unconscious patients, the most common airway obstruction is the tongue. When a person loses consciousness, the muscles in their body relax, including the muscles in the tongue. This relaxation can cause the tongue to fall back and block the airway, making it difficult for the patient to breathe. It is important to recognize this obstruction and take appropriate measures, such as tilting the head back or using a jaw thrust maneuver, to open the airway and ensure proper ventilation.

    Rate this question:

  • 24. 

    The Heimlich maneuver is preformed on ______ adult or children patients.

    • Conscious

    • Unconscious

    • Dead

    • Cardiac arrest

    Correct Answer
    A. Conscious
    Explanation
    The Heimlich maneuver is performed on conscious adult or children patients. This means that the maneuver is intended for individuals who are awake and aware. The purpose of the maneuver is to help dislodge an object that is blocking the airway and causing choking. Performing the maneuver on unconscious or dead individuals would not be effective or appropriate, as they may require different forms of medical intervention. Similarly, cardiac arrest refers to a condition where the heart has stopped beating, and in such cases, immediate cardiopulmonary resuscitation (CPR) is typically required instead of the Heimlich maneuver.

    Rate this question:

  • 25. 

    Poor lung compliance is the inability of the alveoli to expand fully during  inhalation.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Poor lung compliance refers to the decreased ability of the lungs to expand fully during inhalation. This can be caused by various factors such as lung diseases, inflammation, or scarring of the lung tissue. When lung compliance is poor, the alveoli, which are responsible for gas exchange, cannot fully expand, leading to reduced lung function and difficulty in breathing. Therefore, the statement "Poor lung compliance is the inability of the alveoli to expand fully during inhalation" is true.

    Rate this question:

  • 26. 

    Suctioning removes not only obstuctions but what other major thing that the patient needs?

    Correct Answer
    oxygen
    O2
    o2
    Explanation
    Suctioning removes not only obstructions but also oxygen, which is a major thing that the patient needs. Suctioning involves the use of a suction catheter to remove secretions or other substances that may be blocking the airway. However, during the suctioning process, there is a risk of removing oxygen along with the obstructions. Therefore, it is crucial to monitor the patient's oxygen levels and provide supplemental oxygen if necessary to ensure adequate oxygenation during and after suctioning.

    BVM device provides less tidal volume than mouth-to-mouth ventilation, but it delivers a much higher oxygen concentration.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The explanation for the given correct answer is that the BVM device, also known as a bag valve mask, is a manual resuscitator used to provide artificial ventilation to a person who is not breathing or is breathing inadequately. While it may deliver less tidal volume (the amount of air moved in and out of the lungs during each breath) compared to mouth-to-mouth ventilation, it compensates by delivering a much higher concentration of oxygen. This is because the BVM device is connected to an oxygen source, allowing for a higher concentration of oxygen to be delivered to the patient.

    Rate this question:

  • 30. 

    Indications that artifical ventilations are inadequate are

    • Ventilation delivered too fast or to slow

    • Equal chest rise and fall

    • Heart rate does not return to normal range

    • Adequate breath sounds

    • Minimal or no chest rise and fall

    Correct Answer(s)
    A. Ventilation delivered too fast or to slow
    A. Heart rate does not return to normal range
    A. Minimal or no chest rise and fall
    Explanation
    The indications that artificial ventilations are inadequate include ventilation delivered too fast or too slow, heart rate not returning to normal range, and minimal or no chest rise and fall. These signs suggest that the ventilation is not effectively providing enough oxygen to the patient's lungs, resulting in inadequate ventilation.

    Hypoxia develops in the vital organs of patients who are not breathing or

    • Breathing adequately

    • Not talking

    • Not breathing adequately

    • Unconscious

    Correct Answer
    A. Not breathing adequately
    Explanation
    Hypoxia is a condition where there is a lack of oxygen supply to the body's vital organs. When a person is not breathing adequately, it means that they are not taking in enough oxygen into their lungs, leading to a decrease in oxygen levels in the blood. This can result in hypoxia, which can be harmful to the vital organs as they require oxygen to function properly.

    If a patient has a stoma and no tube in place then use a _____ with your BVM device to make a seal over the stoma.

    • Adult mask

    • Child/infant mask

    • A mask that fits the patient

    • Connect the BVM to the stoma and ventilate

    Correct Answer
    A. Child/infant mask
    Explanation
    When a patient has a stoma and no tube in place, using a child/infant mask with the BVM device is recommended. This is because the size of the child/infant mask is smaller and more appropriate for creating a seal over the stoma, ensuring effective ventilation. Using an adult mask or a mask that fits the patient may not provide a proper seal and may lead to inadequate ventilation. Connecting the BVM directly to the stoma and ventilating may not be practical or feasible in this situation.
