Latest
(Ch. 11) What are the two principle purposes for
oropharyngeal airway (OPA) use? Ans: 1. keep tongue from
blocking the upper airway
2. Make suctioning easier
(Ch. 11) What are the indications for OPA use? Ans: Used for
unresponsive patients without a gag reflex to open an airway
(Ch. 11) What are the contraindications for OPA use? Ans: 1.
Patient is conscious
2. Patient has gag reflex when unresponsive
(Ch. 11) How do you measure an OPA before insertion? Ans:
Size the airway adjunct from the earlobe to the corner of the
mouth
(Ch. 11) As you insert an OPA into an unresponsive patient, she
begins to gag violently. You should do what? Ans: prepare to
log roll and suction the oropharynx
(Ch. 11) What are the indications for nasopharyngeal use? Ans:
Semiconscious or unconscious patient with an intact gag reflex
(laryngospasm)
(Ch. 11) What are the contraindications for NPA use? Ans: 1.
Severe head injury with blood draining from the nose
,2 for specific request mail
2. History of fractured nasal bone
(Ch. 11) How do you measure an NPA before use? Ans: Measure
from the tip of the nose to the patient's earlobe
(Ch. 11) What is internal respiration? Ans: Exchange of oxygen
and carbon dioxide between the systemic circulatory system
and cells of the body; internal-think deep within the body
(Ch. 11) What is external respiration? Ans: also called
pulmonary respiration, process of exchanging oxygen and
carbon dioxide between the alveoli and pulmonary capillaries
(Ch. 11) What is the difference between ventilation and
external respiration? Ans: -external respiration is a
physiological process
-ventilation is the mechanical process of moving air into the
lungs i.e. pressure differences, accessory muscle use
(Ch. 11) How do chemoreceptors monitor levels of oxygen?
Ans: Central chemoreceptors sense drops in pH of CSF or
increases in CO2 stimulating the medulla to increase
respiratory rate (hyperventilation), thus removing more CO2
from the body
(Ch. 11) What happens when a ventilation/perfusion (V/Q
ratio) occurs? Ans: A disruption in blood flow inhibits the
exchange of carbon dioxide and oxygen in the lungs, even
though the alveoli are filled with fresh oxygen
(Ch. 11) What is a normal respiratory rate for adults, children,
and infants? Ans: Adults: 12-20
Children: 15-30
,3 for specific request mail
Infants: 30-60
(Ch. 11) What are indications for oxygen delivery? Ans: 1.
SpO2: <94%
2. Hypoxia signs
3. Respiratory distress or failure
(Ch. 11) What are normal signs of adequate breathing for adult
patients? Ans: 1. RR: 12-20
2. Clear and equal lung sounds bilaterally
3. Regular and equal chest rise and fall
4. Adequate tidal volume (depth)
(Ch. 11) When should jaw-thrust be used over a head-tilt chin
lift? Ans: If trauma to the head or spine is suspected
(Ch. 11) How long should you suction for adults, children, and
infants? Ans: 1. Adults- 15 seconds
2. Children- 10 seconds
3. Infants- 5 seconds
(Ch. 11) How do you properly suction a patient? Ans: Suction
while withdrawing the catheter from the oropharynx
(Ch. 11) How do you test a mechanical suction device? Ans:
Clamp the tubing and ensure it generates a vacuum pressure
of more than 300 psi
, 4 for specific request mail
(Ch. 11) What is a french (whistle-tip) catheter? Ans: A flexible
alternative to a rigid catheter that is used in patients with
stomas, clenched teeth, or if suctioning the nasal cavity is
necessary
(Ch. 11) What is the flow rate and oxygen delivery % for a non-
rebreathing mask? Ans: 15 L/min, Up to 90%
(Ch. 11) What is the flow rate and oxygen delivery % for a bag-
mask device? Ans: 15 L/min, nearly 100%
(Ch. 11) What is the flow rate and oxygen delivery % for a nasal
cannula? Ans: 1-6 L/min, 24-44%
(Ch. 11) What should you do if the reservoir bag of a NRB
collapses during inhalation? Ans: Increase the flow rate of
oxygen
(Ch. 11) When should a non-rebreathing mask be applied? Ans:
For moderate to severe respiratory distress if respiratory rate
is greater than 8 or less than 30
(Ch. 11) When should a bag-mask device be applied? Ans: To
deliver high concentrations of O2 to patients who are not
ventilating properly
(Ch. 11) How does continuous positive airway pressure (CPAP)
work? Ans: CPAP increases pressure in the lungs/chest
resulting in reduced venous return and cardiac output
(monitor BP!) and pushes oxygen across the alveolar
membrane. Also opens collapsed alveoli, prevents further
alveolar collapse, and forces interstitial fluid back into
pulmonary circulation
