When testing a mechanical suctioning unit, you should turn on the device, clamp
the tubing, and ensure that it generates a vacuum pressure of more than:
- 00 mm Hg.
- 400 mm Hg.
- 200 mm Hg.
- 300 mm Hg.
300 mm Hg.
A patient who is suspected of being hypoxic and is breathing adequately should be
given supplemental oxygen with a:
- bag-valve mask.
- nasal cannula.
- mouth-to-mask device.
,- nonrebreathing mask.
nonrebreathing mask.
In which of the following patients would the head tilt-chin lift maneuver be the
MOST appropriate method of opening the airway?
- A 50-year-old male who is unconscious following head trauma
- A 24-year-old male who is found unconscious at the base of a tree
- A 45-year-old male who is semiconscious after falling 20 feet
- A 37-year-old female who is found unconscious in her bed
A 37-year-old female who is found unconscious in her bed
A 19-year-old female is found unconscious by her roommate. Your primary
assessment reveals that her breathing is inadequate. As you insert an oropharyngeal
airway, she begins to gag violently. You should:
- continue to insert the airway as you suction her oropharynx.
- insert the airway no further but leave it in place as a bite block.
,- remove the airway and be prepared to suction her oropharynx.
- select a smaller oropharyngeal airway and attempt to insert it.
remove the airway and be prepared to suction her oropharynx.
Which of the following is the MOST reliable indicator of adequately performed
bag-valve mask ventilations in an apneic adult with a pulse?
- Twenty breaths/min being delivered to the adult
- Adequate rise of the chest when squeezing the bag
- Consistently increasing heart rate
- Decreased compliance when squeezing the bag
Adequate rise of the chest when squeezing the bag
Which of the following statements regarding normal gas exchange in the lungs is
correct?
- The oxygen content in the alveoli is highest during the exhalation phase.
- Blood that returns to the lungs from the body has low levels of carbon dioxide.
, - Oxygen and carbon dioxide diffuse across the alveolar walls and capillaries.
- The actual exchange of oxygen and carbon dioxide occurs in the capillaries.
Oxygen and carbon dioxide diffuse across the alveolar walls and capillaries.
You are ventilating a patient with a stoma; however, air is escaping from the mouth
and nose. To prevent this, you should:
- ventilate with less pressure.
- seal the mouth and nose.
- thrust the jaw forward.
- thoroughly suction the stoma.
seal the mouth and nose.
Which of the following statements regarding breathing adequacy is correct?
- A patient with slow respirations and adequate depth will experience an increase
in minute volume.
- The single most reliable sign of breathing adequacy in the adult is his or her
respiratory rate.
