NCM 109 (RLE) 2F OXYGEN
THERAPY EXAM QUESTIONS
AND ANSWERS
Hypoxia - Answer-Is inadequate tissue oxygenation at the cellular level. It results from a
deficiency in oxygen delivery or oxygen use at the cellular level. It is a life-threatening
condition. Untreated it produces possibly fatal cardiac dysrhythmias.
Eupnea - Answer-Is the normal, good, unlabored breathing, sometimes known as quiet
breathing or resting respiratory rate.
Tachypnea - Answer-Rate of breathing is regular but abnormally rapid. Is a medical
term that refers to fast, shallow breathing. Greater than 20 breaths/min
Bradypnea - Answer-Rate of breathing is regular but abnormally slow. Less than 12
breaths/min.
Apnea - Answer-Is the absence of respirations lasting for 15 seconds or longer.
Persistent cessation results in respiratory arrest.
Obstructive sleep apnea - Answer-(Types of Apnea)
The more common form that occurs when throat muscles relax.
Central Sleep apnea - Answer-(Types of Apnea)
Occurs when your brain doesn't send proper signals to the
muscles that control breathing.
Complex sleep apnea syndrome - Answer-(Types of Apnea)
Also known as treatment-emergent central sleep apnea, which occurs when someone
has both obstructive sleep apnea and central sleep apnea.
Hyperventilation - Answer-Lungs remove carbon dioxide faster than it is produced by
cellular metabolism. Rate and depth of respirations increase. Hypocarbia sometimes
occurs.
Cheyne-Stokes respiration - Answer-Occurs when there is decreased blood flow or
injury to the brainstem. Respiratory rate and depth are irregular, characterized by
alternating periods of apnea and hyperventilation.
, Biot's (cluster) breathing pattern - Answer-Is characterized by regular deep respirations
interspersed with periods of apnea. Respirations are abnormally shallow for two to three
breaths, followed by irregular period of apnea.
Orothopnea - Answer-Shortness of breath or difficulty breathing when you're lying down.
Dyspnea - Answer-Refers to the sensation of difficult or uncomfortable breathing and
sometimes described as "air hunger"
1. Upper airway obstruction
2. Lower airway obstruction
3. Complete airway obstruction
4. Acute airway obstructions
5. Chronic airway obstructions - Answer-Types of airway obstruction
Upper airway obstruction - Answer-(Types of airway obstruction)
occurs in the area from your nose and lips to your
larynx
Lower airway obstruction - Answer-(Types of airway obstruction)
occurs between your larynx and the narrow
passageways of your lungs
Complete airway obstruction - Answer-(Types of airway obstruction)
does not allow any air to pass
Acute airway obstruction - Answer-(Types of airway obstruction)
blockages that occur quickly. Choking on a foreign
object is one example
Chronic airway obstruction - Answer-(Types of airway obstruction)
occur two ways: by blockages that take a long time
to develop or blockages that last for a long time
Crackles - Answer-(Adventitious breath sounds)
discontinuous, brief, popping sounds
Wheezes - Answer-(Adventitious breath sounds)
continuous, musical sounds, high or low pitched; usually more
pronounced in expiration
Pleural rub - Answer-(Adventitious breath sounds)
Creaking or grating sounds that have been described as being
similar to walking on fresh snow
Stridor - Answer-(Adventitious breath sounds)
