• Question 2
• Question 1
A patient with respiratory failure has hemodynamic monitoring
and
... [Show More] is receiving mechanical ventilation with peak endexpiratory pressure (PEEP) of 10 cm H2O. Which information
indicates that a change in the ventilator settings may be
required?
a. The arterial line shows a blood pressure of 90/46.
b. The pulmonary artery pressure (PAP) is decreased.
c. The cardiac monitor shows a heart rate of 58 beats/min.
d. The pulmonary artery wedge pressure (PAWP) is increased.
Correct
Answer: The hypotension indicates that the high intrathoracic
pressure caused by the PEEP may be de-creasing
venous return and cardiac output (CO). Decreasing the
PEEP should decrease the intrathoracic pressure and
improving venous return and cardiac output.
The APRN is monitoring a newly intubated patient. He appears
to be very anxious and “fighting” the ventilator. What would be
the most appropriate action?
Correct
Answer: Remove the patient from the ventilator and bag him
with 100% FIO2. If the patient improves, then the
problem is with the ventilator. Respiratory professional
should check the ventilator function.
If the patient does not improve, the problem is with
the patient. If death appears imminent, airway
obstruction pneumothorax, and dislodged
endotracheal tube must be considered as the cause. If
death is not imminent, close examination of the
patient and chest X-ray should be completed. The
need for additional sedation should be considered as

A 59 year old man was admitted to the ICU for a COPD
exacerbation. He was intubated earlier in the day. Initially after
being intubated his static pressure was 23 cm H2o and peak
pressure 47 cm H20. The APRN is notified that currently his
peak pressure has risen to 62 cm H20 and the static pressure is
42 cm H20. His heart rate has increased from 88 to 112beats /
minute and his blood pressure has decreased from 112/88 to
92/ 72. He has decreased breath sounds on the left side.
Where do you think the problem lies with this particular
patient? [Show Less]
