A patient admitted for acute asthma is being discharged to home. The respiratory
therapist notices an order for oral theophylline. Which of the following additional
orders might the therapist expect?
A. point-of-care blood glucose monitoring
B. periodic theophylline blood level check
C. Dilantin for treatment of seizure activity
D. monthly measurement of DLco
Give this one a try later!
, B. periodic theophylline blood level check
For a patient who is taking oral theophylline, which is a xanthine medication,
blood levels must be monitored to ensure adequate bronchodilation.
Theophylline levels should be maintained between 10 and 20 µg. A
theophylline level higher than that range can produce such negative
clinical outcomes as seizures and death. A theophylline level lower than the
range is simply said to be sub-therapeutic and does not provide long-term
bronchodilation control.
A volume-pressure ventilator graphic is observed on a patient who is receiving VC
A/C ventilation on the following settings:
FIO2 0.4
Mandatory rate 16/min
Total rate 20/min
VT 450 mL
Flow 50 L/min
PEEP 5 cm H2O
(FISH TAIL GRAPH)
The patient seems anxious and SpO2 is fluctuating between 89-94%. The therapist
should suggest
A. utilizing flow triggering
B. increasing VT
C. increasing inspiratory flow rate
D. decreasing sensitivity
Give this one a try later!
A. utilizing flow triggering
This pressure-volume loop demonstrates that the patient is required to
inhale significantly before the ventilator is triggered, thereby producing
significant negative pressures to actuate a ventilator breath. This increase in
, work of breathing can cause the patient to deteriorate. One way of dealing
with this is to increase the sensitivity so that the ventilator actuates more
quickly with a negative deflection in pressure. However, this is not an
option in the question. Flow triggering is another more sensitive way to
detect patient effort and actuate a ventilator breath.
A patient is orally intubated and receiving mechanical ventilation. The respiratory
therapist notes the PetCO2 monitor is persistently reading 60 mmHg. Which of the
following can the therapist conclude?
A. the patient is being hyperventilated
B. the CO2 detector is covered with condensate
C. minute ventilation should be increased
D. the infrared device is not working properly
Give this one a try later!
C. minute ventilation should be increased
End-tidal CO2 is correlated to arterial CO2. An end-tidal CO2 reading of 60
mmHg correlates with an arterial CO2 of 70 mmHg. This is clearly
hypoventilation and should be addressed by increasing minute ventilation.
A newborn has a one-minute APGAR score of 6. The respiratory therapist should
A. obtain an arterial blood gas
B. begin cardiopulmonary resuscitation
C. administer supplemental oxygen
D. monitor the infant, reassess in 4 minutes
Give this one a try later!
, C. administer supplemental oxygen
An Apgar score can be used to determine the appropriate intervention of
an infant without knowing the details of the score. A score from 0-3
indicates a need for cardiopulmonary resuscitation. A score from 4-6
indicates the infant requires supplemental oxygen, warming, and general
stimulation. A score of 7-10 is normal in indicates routine care, which
includes drying the infant and placing on a radiant warmer.
Which of the following conditions would benefit most from polysomnography?
A. obesity with increased day-time sleepiness
B. suspected increased airway resistance
C. COPD
D. congestive heart failure
Give this one a try later!
A. obesity with increased day-time sleepiness
Polysomnography is another word for sleep study. An obese patient who
has daytime sleepiness would benefit most from polysomnography. Keep
in mind that Polysomnography is the study of the problem - not the
solution. But it must be done for diagnostic purposes and in order to find
the adequate CPAP setting.
Heated humidification would be most important for a patient using
A. an endotracheal tube
B. a 6 L/min nasal cannula
C. a face tent with an air entrainment device set at 50%
D. a Venturi mask set at FIO2 0.5
