EMT Airway Practice Test 1

An oral and nasal airway should be:

What type of medication opens the bronchi and increases the effectiveness of breathing when a patient has asthma?

What is the maximum flow rate for a nasal cannula?

To provide oxygen therapy at “100%,” what should the flow rate be on a nonrebreather mask?

What airway opening maneuver should be used on a patient that has fallen off a ladder and is suffering from respiratory distress?

A device that delivers a specific amount of medication to the lungs in the form of a short burst of aerosolized medicine that the patient inhales is known as a(n)?

The anatomy of the airway consists of the upper and lower airways. The upper airway starts at the mouth and nares and ends at the _________?

The tongue is often a source of airway obstruction; it falls back and occludes the _________?

The lower airway ends at the alveoli, where gas exchange occurs. Oxygen moves to the hemoglobin by passing through a semipermeable membrane.

Where does this occur?

To create negative pressure in the thorax (chest cavity) the diaphragm contracts and moves _____________. This action expands the volume of the thorax, allowing air to rush into the lungs.

Which of the following ventilatory techniques is likely to yield the LOWEST tidal volumes?

You are transporting an elderly male patient in respiratory distress with a history of COPD…

The patient has very shallow, rapid respirations with minimal chest wall motion and slight wheezing in the upper lung fields. Given this situation, what would you expect the arterial carbon dioxide levels to be?

You are transporting a 48-year-old male patient between medical facilities…

While obtaining the patient’s history, you learn that the patient was involved in a fall at work and suffered a hip fracture and a head injury.

The patient is now presenting with labored breathing at 30/min that has progressively worsened over the last 24 hours, a heart rate of 104, and a blood pressure of 98/70. On auscultation, you hear diffuse rales.

The patient denies any complaints of pain other than those related to his recent fall.

What is the most likely cause of the patient’s respiratory distress?

Which of the following is the most effective method for administering ventilations on an apneic patient?

What structure prevents food and liquid from entering the trachea during swallowing?
