When you have an unresponsive patient with an unknown mechanism of injury, how should you open their airway?

  1. By using the log roll technique.
  2. By using the jaw thrust maneuver.
  3. By using the head-tilt / chin-lift.
  4. By using the tongue-jaw lift.

Answer(s): B

Explanation:

When a patient has a potential spinal injury, it is advised to use the jaw thrust. The remaining methods don’t facilitate simultaneous opening of the airway with cervical spine precautions.



Your patient has shallow respirations and bradypnea.
What will this likely cause?

  1. Easier visibility of the patient’s chest rising and falling.
  2. A decrease in minute volume.
  3. A rise in (SaO2) ‘pulse oximetry’ readings.
  4. A reduction in carbon dioxide levels.

Answer(s): B

Explanation:

When a patient has shallow respirations and bradypnea, these can both contribute to a decrease in minute volume. Neither of these will make the chest rise more visible, nor will they increase the pulse oximeter reading or reduce the carbon dioxide levels.



You have a 36-year-old female patient who is suddenly having difficulty breathing. She is feeling anxious, has intercostal retractions and nasal flaring. Her respiratory rate is 24 breaths per minute. You don’t have a pulse oximeter with you.
What should you do?

  1. You should administer oxygen via non-rebreather mask at 15 LPM.
  2. You should withhold oxygen until a pulse oximeter reading is obtained.
  3. You should apply a nasal cannula at 4 LPM.
  4. You should begin positive pressure ventilations.

Answer(s): A

Explanation:

If you have a patient who is showing signs of hypoxia, you should administer supplemental oxygen. The NRB mask is the best technique to administer oxygen to patients who are in respiratory distress who are breathing adequately and who have no pulse oximeter reading.



Which of the following types of patients would have an oropharyngeal airway?

  1. A 35-year-old patient who is semiconscious.
  2. A 14-year-old patient who is conscious.
  3. A 22-year-old patient with dyspnea who is confused.
  4. A 44-year-old patient who is unconscious.

Answer(s): D

Explanation:

OPAs are for patients who are unresponsive and who would not have a gag reflex.



You have a patient with a stoma bag. You are required to ventilate him. You note that air is escaping from his mouth and nose with each breath.
What should you do?

  1. You should perform a thrust maneuver.
  2. You should manually seal the mouth and nose.
  3. You should open your patient’s airway using a head-tilt and chin-lift.
  4. You should reduce the tidal volume of each of the ventilations.

Answer(s): B

Explanation:

When a patient has a stoma, you should be sure to seal their mouth and nose when ventilating them. This will prevent air leakage. Using the jaw thrust or head-tilt and chin-lift will not prevent air leakage. If you reduce the tidal volume, it could potentially lead to inadequate ventilations.



What does the hypoxic respiratory drive monitor in the human body?

  1. Oxygen levels
  2. Carbon dioxide levels
  3. Blood glucose levels
  4. The pulse oximetry (SaO2) reading

Answer(s): A

Explanation:

The body’s backup system to the CO2 drive is called the hypoxic drive. Its function is to monitor the blood’s oxygen levels. (Not CO2 or blood glucose!) The pulse oximeter is an external patient monitoring device.



You should administer a non-rebreather mask to:

  1. patients who are breathing slowly and taking shallow breaths.
  2. patients who have a reduced tidal volume.
  3. patients who are breathing adequately but are showing signs of hypoxia.
  4. patients who are breathing inadequately.

Answer(s): C

Explanation:

Non-rebreather masks are indicated for patients who are breathing spontaneously with adequate ventilations and who show signs of hypoxia. Patients who have inadequate, slow or shallow ventilations should be ventilated.



You have a 6-year-old patient in your care that is in respiratory distress. The pulse oximeter (SaO2) reads 93%. How must you manage your patient?

  1. You should contact your patient’s pediatrician before transporting him.
  2. You should administer enough oxygen in order to maintain a pulse oximeter reading of at least 94%.
  3. You should not administer oxygen until your patient develops accessory muscle use.
  4. You should administer a metered dose inhaler if it has been prescribed to your patient’s parent or sibling.

Answer(s): B

Explanation:

Oxygen is given to patients who present signs or symptoms of hypoxia, including a pulse oximeter below 94%. EMTs should not withhold oxygen from any patient who has a pulse oximeter under 94%. It is not up to the EMTs to contact the patient’s physician for medical instructions and they shouldn’t administer MDIs which have not been prescribed to the patient.
