1
The nurse notices cyanosis of the lips during the respiratory assessment. This is a
sign of air being trapped in the alveoli
late sign of O2 deprivation
sign of labored breathing
early sign of O2 deprivation
2
What is the physiological mechanism behind ARDS?
Airflow obstruction
Damaged blood vessels leak fluid into alveolar interstitium
Perforation of the bronchi
Excess fluid prevents adequate gaseous exchange
3
Pulse oximetry is non-invasive & measures:
Hematocrit
Red blood cells
Arterial carbon dioxide
Arterial oxyhemoglobin
4
Is this Compensated or Uncompensated Respiratory Acidosis? pH 7.25, pCO2 55, pO2 60, HCO3 25
Beats me
Who knows?
Compensated
Uncompensated
5
Why does a patient with a PE's O2 sat not improve with oxygen administration?
Oxygen is a conspiracy and nobody actually needs it
The clot interferes with perfusion in the lungs
The O2 sensor usually does not work on patients with a PE
The patient has to be intubated for O2 sats to improve
6
Which is not a hazards of oxygen therapy:
Rash
Combustion
Drying of mucous membranes
Toxicity
7
The type of oxygen delivery system shown below is a
Venturi mask
standard oxygen mask
non-rebreather mask
partial rebreather maks
8
The goal of selecting a specific FIO2 is to achieve acceptable PaO2 within which range?
100-120 mmHg
50-60 mmHg
40-55 mmHg
60-100 mmHg
9
Capnography is only useful in intubated patients.
Yes, that is true.
What in the world is capnography?
I have no idea.
No, that is false.
10
What does Capnography measure?
CO2 being inhaled
Oxygen intake
End tidal carbon dioxide
O2 being exhaled
11
What is a side effect of PEEP?
Pulmonary bronchoconstriction
Hypertension
Decreased venous return
Hypervolemia
12
It is common to see an increase in ETCO2 reading when _____ is achieved.
a goal
cardiac arrest
return of spontaneous respiration

15
Prior to drawing an ABG the nurse will assess _______ to ensure patient safety?
ETOH level
Morse Scale
Allen Test
Braden Score
16
To administer 100% FiO2 @ 15 LPM, the nurse should use:
simple face mask
non-rebreather mask
venturi mask
nasal cannula
17
Pulse oximetry readings should be correlated with which other assessment or findings?
Changes in blood pressure
The hemoglobin level of the blood
The vital signs
The respiratory assessment
18
The nurse palpates "crepitus" during the respiratory assessment. This term means
inflammation of the sinuses
infection of the sinuses
patient is hyperventilating
subcutaneous emphysema
19
How long should an intubation attempt go uninterrupted before administering oxygen?
no more than 30 seconds
5 minutes
It is fine as long as the oxygen saturation is above 90%
1 hour
20
What is the desired range for capnography?
80-100
25-35
50-65
35-45
