1:  The aspect of natural ventilation that involves the diaphragm contracting and the chest wall expanding is:
A: metabolism.
B: inhalation.
C: exhalation.
D: airway expansion.

2:  The path air takes during exhalation goes through the following route:
A: Alveoli, bronchioles, bronchi, trachea, epiglottis, oropharynx
B: Oropharynx, larynx, trachea, carina, bronchi, alveoli
C: Bronchioles, carina, larynx, oropharynx, epiglottis
D: Alveoli, trachea, carina, epiglottis, pharynx, mouth

3:  The process by which carbon dioxide moves from a high concentration in the capillaries to the lower concentration in alveoli is:
A: ventilation.
B: hypoxia.
C: wicking.
D: diffusion.

4:  A patient who is developing early stages of hypoxia may exhibit:
A: cyanosis.
B: restlessness.
C: a weak pulse.
D: a pulse oximetry reading below 80%.

5:  A patient who to takes an occasional gasping breath after their heart has stopped has:
A: agonal respirations.
B: ataxic respirations.
C: apneic respirations.
D: hypoxic respirations.

6:  When inserting a nasopharyngeal airway, it is important to do all the following except:
A: Measure the size from the tip of the nose to the earlobe.
B: Ensure that the bevel faces the septum when inserting into the right nare.
C: Insert with a constant rotating motion.
D: Lubricate the airway with a water-based lubricant.

7:  If a D-sized oxygen cylinder contains 300 L of oxygen and is at 2,000 PSI at the start of call, the best estimate for the amount of time a patient can receive 15 L/min with a nonrebreathing mask is:
A: 10 minutes.
B: 20 minutes.
C: 30 minutes.
D: 40 minutes.

8:  Properly performed suctioning of a patient may still cause:
A: hypoxia.
B: vomiting.
C: gastric distention.
D: aspiration.

9:  When using a bag-valve-mask device, the key finding to observe to assure adequate ventilation is:
A: three seconds between squeezing the bag and lifting the mask off the face.
B: the patient's weight in kilograms.
C: good chest rise and fall.
D: the location of the patient's cricoid cartilage.

10:  The most common complication of the flow-restricted, oxygen-powered ventilation device is:
A: pneumothorax.
B: hypoventilation.
C: cricoid pressure.
D: gastric distention.
