A 1000 g neonate (normal baby is 3000 g) is stable in nicu. Which of the following
should the respiratory therapist use to monitor the neonates overall cardiopulmonary
status.
a. TcPCO2 and TcPO2 monitor
b. Arterial blood gas analysis Q4
c. SpO2 monitor
d. Capillary gas analysis Q8 - CORRECT ANSWER: Since the baby is stable, go less
invasive, also go continuous monitoring (not 4 hour or 8 hour), Transcutaneous (Tc)
continuous monitoring of CO2 and O2 is the best. Answer is A
A 16-year-old male patient involved in a motorcycle accident presents to the ER with
massive maxillary and nasal trauma. Which of the following devices would be most
appropriate for maintaining the patient's airway?
A. nasal endotracheal tube
B. fenestrated tracheostomy tube
C. oral pharyngeal airway
D. oral endotracheal tube - CORRECT ANSWER: Patient with massive maxillary and
nasal trauma would be difficult to intubate; you might need to bypass the face
completely, so ANSWER is B, fenestrated tracheostomy tube (could be fenestrated or
not fenestrated, either would work).
A 2 kg (4.4 lb) neonate requires transportation to a tertiary care center for cardiac
surgery. The infant has a heart rate of 140 and a BP of 60/30.The neonate is intubated
with a size 2.5 mm uncuffed endotracheal tube and ventilation is being assisted
manually at a rate of 40/min. Which of the following should the respiratory therapist
recommend?
A. postpone the transport until the neonate has spontaneous respirations
,B. prepare for the transport immediately
C. delay the transport and stabilize the patient
D. wait 24 hours and then reassess the patient - CORRECT ANSWER: Answer is B.
A 2-year old child enters the emergency room. The mother states that the child was
playing with friends and developed violent coughing and unilateral wheezing. Physical
examination reveals a hyperresonant percussion note on the left and resonant
percussion on the right. Inspiratory and expiratory chest films indicate air trapping with
no foreign bodies "noted." The respiratory therapist should suspect the child has.
a.pneumothorax
b.orthopnea
c.aspirated a foreign object
d.tachyphylaxis - CORRECT ANSWER: Unilateral wheezing indicates aspirated object
and fact that the child was playing with friends causes you to believe the child inhaled a
small toy or something, hyperresonant percussion indicates air trapping, so you are
thinking foreign object but x-ray says no foreign bodies "noted." Just because it says
"noted" does not mean something is not there, it just means it could not be seen on the
xray, also if the child had swallowed a small plastic toy, "plastic" does not show up on
xrays (radiolucent). The ANSWER is C
A 24-year-old post-operative male patient is receiving intermittent positive pressure
therapy at 20 cm H2O. The patient complains that the machine is cycling off too soon.
The patient's post-operative spontaneous vital capacity is 3.5 L. Which of the following
should the respiratory therapist recommend?
A. Increase the pressure to 25 cm H2O
B. Discontinue therapy, encourage deep breathing and coughing frequently on his own
C. Switch to a volume incentive spirometry device
D. Recommend decreasing the flow - CORRECT ANSWER: The key is that the patient's
post-operative spontaneous vital capacity is 3.5L, which shows he can take a pretty
good deep breath on his own, so the simplest, easiest ANSWER is B, discontinue
therapy, encourage deep breathing and coughing frequently on his own. If they can do it
on their own, that's the best therapy of all.
,A 26-week gestational age infant requires intensive monitoring and care in the NICU.
Which device would be most appropriate for maintaining a neutral thermal environment
for this infant?
A. radiant warmer
B. isolette
C. croupette
D. bassinet - CORRECT ANSWER: Both the isolette and the radiant warmer can be
neutral thermal environments. The key to this question, making one better than the
other, is access to the patient since this baby requires continuous monitoring.
Supposedly, the radiant warmer provides better access to the baby than the isolette.
A 26-year-old patient with shortness of breath is admitted to the emergency room. The
patient states that he was running in Central Park with a friend and could not catch his
breath. Bedside assessment reveals the following data:
Pulse: 120
Respirations: 25 br/min
Color: pale
SpO2: 89% on room air
Breath sounds: slightly diminished on the right
The respiratory therapist should:
A. request a STAT chest x-ray.
B. administer 100% oxygen.
C. insert a large bore needle into the 2nd intercostal space on the right side in the
midclavicular line.
D. insert a chest tube into the 2nd intercostal space on the right side in the midclavicular
line. - CORRECT ANSWER: Request a STAT x-ray is good but the patient currently has
shortness of breath and is uncomfortable, so what would you do FIRST, ANSWER is B,
administer 100% oxygen
A 27-week gestation age neonate with respiratory distress syndrome is receiving high
frequency oscillatory ventilation at the following settings:
, PIP: 20 cm H2O
Frequency: 12 Hz
I time: 30%
FIO2: 0.55
PEEP: 4 cm H2O
Blood gas results from an umbillical artery line are as follows:
pH: 7.15
PaCO2: 62 torr
PaO2: 46 torr
HCO3-: 22 mEq/L
The respiratory therapist should increase the
A. PEEP.
B. FIO2.
C. frequency.
D. amplitude. - CORRECT ANSWER: This baby is not being ventilated or oxygenated
properly. Always fix ventilation first or the oxygen won't get where it is supposed to
anyway. Amplitude means "pressure",
so ANSWER is D, Increase Amplitude
A 28-week gestational age infant with severe respiratory distress syndrome is being
mechanically ventilated in the PC, SIMV mode at the following settings:
Flow rate: 6 L/min
Set rate: 32 br/min.
PIP: 28 cmH2O
FIO2: 0.70
