ANSWERS GRADED A+
✔✔artificial ventilation of an apneic patient who has dentures should be_____ -
✔✔Tight-fitting dentures should be left in place because they facilitate the delivery of
adequate tidal volume.
✔✔A patient's skin will MOST likely become cyanotic if he or she has:_____
A:an overall increase in circulating red blood cells.
B:a decrease in the amount of carbon dioxide.
C:a decrease in the amount of arterial oxygen.
D:an increase in the amount of arterial oxygen. - ✔✔C:a decrease in the amount of
arterial oxygen.
✔✔A 40-year-old man is conscious, but has an increased rate of breathing. You
should:_____
A:apply 100% oxygen via nonrebreathing mask.
B:assist his ventilations with a bag-mask device.
C:immediately insert a nasopharyngeal airway.
D:assess the regularity and quality of breathing. - ✔✔D:assess the regularity and quality
of breathing;
✔✔A 40-year-old man is conscious, but has an increased rate of breathing. You should:
A:apply 100% oxygen via nonrebreathing mask.
B:assist his ventilations with a bag-mask device.
C:immediately insert a nasopharyngeal airway.
D:assess the regularity and quality of breathing. - ✔✔D:assess the regularity and quality
of breathing;
On the basis of this assessment, the most appropriate treatment can be provided—
oxygen via a nonrebreathing mask or some form of positive-pressure ventilation
✔✔Which of the following describes the correct technique for inserting a
nasopharyngeal airway?_____
A:Insert the device with the bevel facing the septum.
B:Apply firm, gentle pressure if you meet resistance during insertion.
C:Insert the device with the bevel facing the lateral part of the nose.
D:Rotate the device as you insert it into the right nostril. - ✔✔A:Insert the device with
the bevel facing the septum.
✔✔A 56-year-old man has labored, shallow breathing at a rate of 28 breaths/min. He is
responsive to pain only. You should:_____ - ✔✔insert a nasopharyngeal airway and
begin assisting his ventilations.
, ✔✔The MOST effective way to determine if you are providing adequate volume during
artificial ventilation is: - ✔✔assessing the chest for adequate rise.
✔✔Medications such as albuterol (Ventolin) relieve respiratory distress by:_____
A:constricting the bronchioles in the lungs.
B:dilating the large mainstem bronchi of the airway.
C:relaxing the smooth muscle of the bronchioles.
D:contracting the smaller airways in the lungs. - ✔✔B:dilating the large mainstem
bronchi of the airway;
(bronchodilators cause dilation=open air passages
✔✔A 60-year-old woman presents with acute respiratory distress. She is conscious and
alert, but restless. Her respiratory rate is 26 breaths/min with adequate chest expansion,
her breath sounds are clear to auscultation bilaterally, and her oxygen saturation is
90%. the MOST appropriate treatment______ - ✔✔Supplemental oxygen with a
nonrebreathing mask
✔✔To ensure you deliver the highest concentration of oxygen with a nonrebreathing
mask, you should:
A:make sure that the reservoir bag is preinflated.
B:cover the flapper valves on the oxygen mask.
C:set the flow rate to at least 10 to 12 L/min.
D:securely fasten the mask to the patient's face. - ✔✔A:make sure that the reservoir
bag is preinflated.
✔✔An unresponsive apneic patient's chest fails to rise after two ventilation attempts.
You should:_____
A:immediately proceed to chest compressions.
B:reposition the head and reattempt to ventilate.
C:attempt to ventilate again using more volume.
D:suction the airway and reattempt ventilations. - ✔✔A:immediately proceed to chest
compressions
(initial attempt unsuccessful=reposition the patient's head)
(second ventilation is unsuccessful, assume severe obstruction)
✔✔When ventilating an unresponsive apneic adult with a bag-mask device, you should
ensure that:_____
A:an airway adjunct has been inserted.
B:ventilations occur at a rate of 20 breaths/min.
C:you are positioned alongside the patient.
D:the pop-off relief valve is manually occluded. - ✔✔A:an airway adjunct has been
inserted.
