Ch.11 - Review

The hypoxic drive is influenced by

• low blood carbon dioxide levels

• high blood carbon dioxide levels

• low blood oxygen levels

• high blood oxygen levels

The presence of elevated carbon dioxide levels in the blood is called:

• hypercarbia

• hypoxemia

• hypoxia

• acidosis

Which of the following patients is breathing adequately?

• a conscious male with respirations of 18 breaths/min and reduced tidal volume

• an unconscious 52 y/o female with snoring respirations and cool, pale skin

• a conscious male with respirations of 19 breaths/min and pink skin

• a conscious female with facial cyanosis and rapid, shallow respirations

At a flow rate of 6 L/min, a nasal cannula can deliver an approximate oxygen concentration of up to:

• 24%

• 35%

• 44%

• 52%

which of the following factors will cause a reduction in minute volume in an adult?

• increased tidal volume

• slight increase in respiratory rate

• respirations of 20 breaths/min

• shallow breathing

The pressure of a gas in a full cylinder of oxygen is approximately ___ pounds per square inch (PSI)

• 500

• 3000

• 2000

• 1000

High flow oxygen with a nasal cannula during the preoxygenation phase on endotracheal intubation is called:

• apneic oxygenation

• passive oxygenation

• denitrogenation

• active ventilation

Which of the following oxygen flowmeters is NOT affected by gravity and can be used in any position when attached to an oxygen cylinder?

• bourdon-gauge flowmeter

• pressure-compensated flowmeter

• ball-and-float flowmeter

• vertical-position flowmeter

Which of the following organs or tissues can survive the longest without oxygen?

• heart

• kidneys

• muscle

• liver

an oxygen cylinder should be taken out of service and refilled when the pressure inside it is less than:

• 1000 PSI

• 500 PSI

• 1500 PSI

• 200 PSI
