- An infant is being mechanically ventilated via a time-cycled, pressurelimited ventilator. Which of the following
... [Show More] would occur if PEEP were
increased without a corresponding increase in peak pressure?
• The tidal volume would decrease
- A physician requests the respiratory therapist to assess the upper airway
function of a patient with a fenestrated tracheostomy tube. The therapist
should:
• Remove the inner cannula, deflate the cuff, plug the outer cannula
- A patient receiving sustained maximal inspiratory (SMI) treatments with a
volume-oriented incentive spirometer device begins to inhale through the
device 18 times per minute. Which of the following best explains this
situation?
• The patient needs re-instruction regarding the SMI therapy
- After initiating mechanical ventilation in the A/C mode for an adult male
patient, the respiratory therapist observes that the patient is agitated and
having difficulty in cycling the ventilator. Which of the following should the
therapist do?
• Increase the sensitivity setting
- Data recorded for a 52 kg (110 lb) mechanically ventilated patient who has
a long standing history of chronic hypercapnia are as follows:
Ventilator Settings Arterial Blood Gases
Mode: SIMV
pH: 7.36
VT: 400 mL
PaCO2: 62 mmHg
Rate: 8/min
HCO3: 34 mEq/L
FiO2: 0.35
PaO2: 61 mmHg
On the basis of this information, the respiratory therapist should:
• Maintain current settings
- A respiratory therapist is manually ventilating a patient during a
cardiopulmonary resuscitation attempt. An arterial blood gas is drawn and
the results are as follows:
pH: 7.27
PaCO2: 38 mmHg
HCO3: 17 mEq/L
PaO2: 44 mmHg
Based on this information, the respiratory therapist should do which of the
following?
• Ensure that the manual resuscitator is connected to an oxygen source
- A COPD patient is brought to the ED after several days of increasing
respiratory distress. Baseline blood gases are drawn and the patient is
placed on oxygen at 2 LPM via nasal cannula. Data from the original and a
subsequent arterial blood sample are as follows:
Room Air Sample
pH: 7.23
PaCO2: 82 mmHg
HCO3: 33 mEq/L
PaO2: 49 mmHg
2L nasal O2
pH: 7.33
PaCO2: 66 mmHg
HCO3: 34 mEq/L
PaO2: 54 mmHg
Based on the above information, the respiratory therapist should:
• Increase the oxygen flow to 3L/min and continue to monitor.
- A 16-year-old female has just been admitted to the ED following a bicycling
accident. She is receiving supplemental oxygen via nonrebreathing mask.
While standing at the bedside, the respiratory therapist notes the onset of
ataxic breathing. Which of the following should the therapist do?
• Begin manual ventilation
- A respiratory therapist is performing a chest examination on an adult male
patient. The therapist notes the trachea is deviated to the right with
flatness to percussion on the right. Which of the following best explains
these findings?
• Right sided atelectasis
- A patient in the intensive care unit is receiving supplemental oxygen via
40% air-entrainment mask. Current arterial blood gas results are as follows:
pH: 7.43
PaCO2: 54 mmHg
HCO3: 34 mEq/L
PaO2: 88 mmHg
Which of the following is the correct interpretation for these results?
• Compensated metabolic alkalosis
- While a respiratory therapist is checking the oxygen setup of a patient on
2L/min nasal cannula, the patient complains of not being able to detect
any oxygen flow from the cannula. Which of the following actions is
appropriate at this time?
• Tighten all connections [Show Less]
