9) Before applying a nonrebreather mask, the EMT should take what action? A) Inflate the reservoir bag and make sure the bag does not deflate during inspiration. B) Insert a properly sized oropharyngeal airway. C) Make sure the oxygen supply has greater than 2,000 psi in the tank. D) Connect the mask to a humidified oxygen source and wait for the patient's heart rate to slow.

A

15) You have arrived at the scene of a call for a "man down. As you enter the residence you note that your patient is a male in his mid-60s who is awake but does not seem to acknowledge your presence. He is perspiring profusely, has cyanosis of his ears and lips, and has rapid, shallow respirations. Which of the following should you do first? A) Listen to his lung sounds. B) Assist ventilations with a bag-valve mask and supplemental oxygen. C) Obtain the patient's medical history. D) Check for a radial pulse.

B

18) To calculate the minute volume, you need to multiply what two measurements? A) Alveolar ventilation and respiratory rate B) Tidal volume and respiratory rate C) Tidal volume and dead space air D) Respiratory rate and bronchial dilation

B

21) The process of air moving in and out of the chest is called: A) inhalation. B) ventilation, C) tidal volume. D) respiration.

B

22) Which of the following statements BEST describes the exchange of gas in the alveoli? A) Blood moves by way of the pulmonary capillaries, air arrives at the alveoli, and osmosis occurs. B) Air moves into the alveoli, blood is transported by the pulmonary capillaries, and diffusion occurs C) Air moves into the airway, blood arrives via the pulmonary veins, and osmosis occurs. D) Blood moves from the left heart to the lungs, air arrives the alveoli sacks, and diffusion occurs.

B

1) For life to be maintained, a balance of oxygen and carbon dioxide is needed. The condition when oxygen levels are low called: A) hypotension. B) hyperventilation. C) hypoxia D) hypercarbia

C

16) The movement of oxygen and carbon dioxide between the alveoli and circulating blood is called A) internal respiration. B) cellular respiration. C) pulmonary respiration D) osmosis.

C

17) When does respiratory distress change to respiratory failure? A) When the respiratory challenge continues, the systems fail with the demand for oxygen, pupils dilate, and the skin becomes hot and dry. B) When the patient who is short of breath, with noisy respiration, presents in the tripod position but then suddenly has the condition clear up and return to normal. C) When the respiratory challenge continues, the systems cannot keep up with the demand, and skin color and mental status change D) When the compensatory mechanism is no longer needed and the patient goes into arrest.

C

19) What is the relatively rare condition that can cause respiratory depression? A) The eyes can develop scar tissue on the retina from a high concentration of oxygen. B) High concentration of oxygen can depress breathing when the patient has an allergic reaction from the oxygen. C) Chronic obstructive pulmonary disease (COPD) has changed the stimulus to breathe to the hypoxic drive and high concentration can depress breathing. D) Lungs can react unfavorably to oxygen when the concentration is too high for a long period of time and this can depress breathing.

C

20) Why does a patient involved in an auto crash who has major internal abdominal bleeding require oxygen to maintain internal respiration? A) The swelling of the abdominal space causes the diaphragm to be restricted, which will reduce the thorax space B) The red blood cells have a reduction of hemoglobin that reduces the amount of oxygen that can be transported. C) lack of circulating volume decreases the oxygen and carbon dioxide transport capability. D) A lack of oxygen in the air decreases the oxygen diffused into the bloodstream, which creates an increase of carbon dioxide.
