EMT Airway Quiz 2

When assessing the airway, breathing, and circulation, which one of the following best indicates that the patient has an open airway?

• The patient speaks with ease

• The patient is conscious

• The respiratory rate is normal

• The breath sounds clear

The EMT is correctly performing the jaw-thrust airway maneuver when she:

• maintains the head in a neutral position and slightly tilts the head backward.

• opens the airway by slightly extending the head and thrusting the jaw upward.

• places her hands on the side of the patient's head and lifts the jaw upward.

• places one hand on the forehead and lifts the jaw upward with her other hand.

Which one of the following setups on the bag-valve mask (BVM) will enable the EMT to deliver the highest concentration of oxygen to the patient?

• BVM with oxygen reservoir attached

• BVM with oxygen reservoir attached, receiving oxygen at 15 lpm

• BVM with room-air oxygen being used by two EMT's

• BVM attached to oxygen at 15 lpm

The EMT shows that he is correctly using the flow-restricted, oxygen-powered ventilation device when he:

• administers each ventilation over a 2- to 3-second period.

• stops ventilating as soon as the patient's chest begins to rise.

• increases pressure if the air enters the stomach instead of the lungs.

• ventilates the patient at a rate of 20 breaths per minute.

Which one of the following best describes oxygen?

• A gas classified as a drug

• A moist gas that supports combustion

• An odorless cloudy gas pressurized

• A highly flammable substance

When using a nonrebreather face mask, the EMT recognizes which one of the following?

• The mask is comfortable and well tolerated by all patients when properly applied.

• Approximately 90% of the patient's tidal volume will be oxygen.

• Oxygen is delivered into the lungs even when the patient is not inhaling.

• The air exhaled by the patient will be recycled with oxygen.

A patient was eating dinner when he got a piece of food caught in his throat. Although coughing has failed to remove the food, he remains able to move an adequate amount of air into and out of his lungs. A nasal cannula has been applied and vital signs are stable. During transport, the patient suddenly begins to exhibit stridorous respirations. Your immediate action should be to:

• place the patient supine and suction his airway.

• continue care and transport.

• perform abdominal thrusts.

• start positive pressure ventilation.

You are by the side of a patient who fell 5 feet from a ladder, landing on a concrete porch with lower back and buttocks. Assessment reveals an intact airway, adequate respirations, rapid radial pulse, and skin that is cool and diaphoretic. The patient complains of lower back and left leg pain. No deformity to the extremity is noted; however, the lower back is tender on palpation. The following vital signs are obtained: pulse 132, respirations 20, blood pressure 102/88 mmHg, and SpO2 97% on room air. Regarding oxygen therapy, you would:

• administer oxygen at 15 lpm through a nonrebreather.

• start positive pressure ventilation to support breathing.

• provide 2 lpm O2 through a nasal cannula.

•  recognize a normal SpO2 and forego oxygen therapy.

The difference between respiration and ventilation is best described as:

• Respiration and ventilation are similar terms that both describe normal and healthy breathing in the living organism.

• Ventilation describes the absorption of O2 into the cells while ventilation is the excretion of CO2 from the cells.

• Ventilation describes the exchange of gases at the cellular level while respiration describes the same process in the lungs.

• Respiration describes the exchange of O2 and CO2 while ventilation describes the movement of air that carries them.

Which of the following would cause the greatest decrease in oxygen delivery to the cells?

• Heart rate above 120 beats per minute

• Diastolic blood pressure > 100 mmHg

• Temperature above 103F

• Decreased amount of circulating hemoglobin
