NURA 303 Exam 3 Respiratory Care and
Oxygen Delivery Questions With Correct
Answers
What |is |the |definition |of |Anoxia?
A. |Difficulty |breathing
B. |Absence |of |spontaneous |breathing
C. |Absence |or |almost |complete |absence |of |oxygen |from |inspired |gases, |arterial |blood, |or |
tissues
D. |Increased |respiratory |rate
C. |(Absence |or |almost |complete |absence |of |oxygen |from |inspired |gases, |arterial |blood, |or |
tissues.
Rationale: |Anoxia |refers |to |a |severe |deficiency |of |oxygen |in |the |tissues.)
Apnea |is |defined |as:
A. |A |decrease |in |respiratory |rate
B. |Absence |of |spontaneous |breathing
C. |Deep, |fast |breathing
D. |Shallow, |slow |breathing
B. |(Absence |of |spontaneous |breathing.
Rationale: |Apnea |specifically |indicates |a |pause |in |breathing.)
Which |term |describes |a |respiratory |rate |greater |than |20 |breaths |per |minute?
A. |Bradypnea
B. |Eupnea
C. |Tachypnea
D. |Kussmaul |respirations
C. |(Tachypnea.
Rationale: |Tachypnea |refers |to |an |increased |respiratory |rate.)
What |are |Cheyne-Stokes |respirations |characterized |by?
A. |Deep, |fast |breathing |alternating |with |slow, |shallow |breathing
B. |Shallow, |slow |breathing
C. |Normal |breathing |pattern
D. |Rapid |shallow |breaths
, A. |(Deep, |fast |breathing |alternating |with |slow, |shallow |breathing.
Rationale: |Cheyne-Stokes |is |a |specific |pattern |of |breathing |often |seen |in |certain |medical |
conditions.)
The |term |hypoxemia |refers |to:
A. |Low |oxygen |levels |in |tissues
B. |Low |oxygen |levels |in |the |blood
C. |A |lack |of |spontaneous |breathing
D. |Difficulty |breathing
B. |(Low |oxygen |levels |in |the |blood.
Rationale: |Hypoxemia |specifically |indicates |insufficient |oxygen |in |the |arterial |blood.)
What |distinguishes |ventilation |from |perfusion?
A. |Ventilation |is |the |movement |of |air |perfusion |is |the |passage |of |oxygenated |blood.
B. |Ventilation |occurs |in |the |blood |perfusion |occurs |in |the |lungs.
C. |Ventilation |is |passive |perfusion |is |active.
D. |Both |refer |to |the |same |process.
A. |(Ventilation |is |the |movement |of |air |perfusion |is |the |passage |of |oxygenated |blood.
Rationale: |These |terms |describe |different |processes |in |respiratory |and |circulatory |physiology.)
What |is |the |primary |indication |for |using |a |nasal |cannula?
A. |High-flow |oxygen |delivery
B. |Low-flow |oxygen |delivery |to |patients |with |chronic |obstructive |pulmonary |disease
C. |Emergency |resuscitation
D. |Non-invasive |ventilation
B. |Low-flow |oxygen |delivery |to |patients |with |chronic |obstructive |pulmonary |disease.
Rationale: |Nasal |cannulas |are |commonly |used |for |low-flow |oxygen |delivery |in |various |
settings.)
When |should |humidification |be |provided |during |oxygen |therapy?
A. |Only |for |patients |on |high-flow |oxygen
B. |When |patients |are |experiencing |discomfort |from |dry |mucosa
C. |For |all |patients |receiving |oxygen
D. |Only |for |patients |with |tracheostomies
B. |(When |patients |are |experiencing |discomfort |from |dry |mucosa.
Rationale: |Humidification |helps |alleviate |discomfort |associated |with |dry |airways.)
What |is |the |primary |purpose |of |a |non-rebreather |mask?
A. |To |deliver |a |precise |amount |of |oxygen
