If a patient's ABG results indicate an elevated PaCO2, what changes on the ventilator may be
ordered to correct this? - correct answer ✔✔Increase rate
If a patient's ABG results indicate a low PaO2, what changes on the ventilator may be ordered to
correct this? - correct answer ✔✔Increase FiO2
,What ventilator settings can be changed to correct hypercapnia? - correct answer ✔✔Increase
rate
Increase tidal volume
Add pressure support
What ventilator settings can be changed to correct low oxygenation? - correct answer
✔✔Increase FiO2
Increase PEEP
Which venilator setting provides the patient with a tidal volume? - correct answer ✔✔AC
Which ventilator setting will augment spontaneous breaths by decreasing resistance upon
inspiration? - correct answer ✔✔Pressure Support
Which ventilator setting can be increased to help improve oxygenation? - correct answer
✔✔PEEP
If a patient has an elevated PaCO2 and a normal PaO2 what vent change may be made? -
correct answer ✔✔Increase rate
What would be included in the treatment for a patient with a closed pneumothorax? - correct
answer ✔✔Chest tube insertion
A patient's ABGs are pH 7.15, PaCO2 88, PaO2 55, SaO2 88%, and HCO3 38. What is your
interpretation of her ABGs? - correct answer ✔✔Respiratory acidosis partially compensated
with hypoxemia
, A patient in respiratory acidosis on BiPap is becoming increasingly short of breath, lethargic, and
diaphoretic with a SpO2 of 82%. What is the priority intervention? - correct answer ✔✔Page
the physician STAT for possible intubation
What interventions must be done post-intubation? - correct answer ✔✔Auscultate breath
sounds bilaterally
Portable Chest X-Ray
Monitor vital signs closely
Secure the ETT
The finding of normal breath sounds on the right side of the chest and absent breath sounds on
the left side of the chest in a newly intubated patient is probably due to what? - correct answer
✔✔Right mainstem intubation
The assist control mode of ventilation functions in which of the following manners? - correct
answer ✔✔It delivers gas at a preset volume, at a set rate, and in response to the patient's
inspiratory efforts
What effect does positive pressure ventilation have on cardiac output? - correct answer
✔✔Positive pressure ventilation increases intrathoracic pressure, which decreases venous
return and cardiac output
What is the main sign that a patient is not tolerating weaning from mechanical ventilation? -
correct answer ✔✔An increase in respiratory rate
What is the treatment for a patient who is anxious and hyperventilating with metabolic
alkalosis? - correct answer ✔✔Have the patient breathe into a brown paper bag
What may be ordered for a patient who is experiencing metabolic acidosis? - correct answer
✔✔Administration of sodium bicarbonate
