pt, the RT noticed a significant decrease in pulmonary compliance. Which of the following could
explain the change? - - ANS✔️---a pneumothorax has occurred
Following the initiation of pulmonary artery pressure monitoring for an adult male being
mechanically ventilated, the following data is recorded: PAWP: 24 mm Hg C(a-v)O2: 2-4 vol%
These results are most likely associated with which of the following? - - ANS✔️--hypovolemia
2|Page
,If the PETCO2 is 22 mm Hg and the dead space to tidal volume ratio (VD/VT) is , the resulting
PaCO2 is approximately : - - ANS✔️---45 mm Hg
Which of the following acid-base disorders would most likely be present in a pt with renal failure
who is receiving inadequate mechanical ventilation? - - ANS✔️---metabolic acidosis/respiratory
acidosis
Pts with which of the following conditions are more likely to exhibit a lower than predicted
carbon monoxide diffusing capacity (DLCO)?
1 Idiopathic Pulmonary Fibrosis- YES COPD-YES Anemia-YES Pulmonary Vascular disease-
YES
2 Idiopathic Pulmonary Fibrosis- YES COPD-NO Anemia-YES Pulmonary Vascular disease-
NO
3 Idiopathic Pulmonary Fibrosis- NO COPD-YES Anemia-NO Pulmonary Vascular disease-
YES
4 Idiopathic Pulmonary Fibrosis-YES COPD-YES Anemia-YES Pulmonary Vascular disease-
NO - - ANS✔️--1 Idiopathic Pulmonary Fibrosis- YES COPD-YES Anemia-YES Pulmonary
Vascular disease-YES
The results of a 12-lead ECG obtained from a 44 year old female reveal flattened T waves with
prominent U waves. The RT should suspect: - - ANS✔️---electrolyte deficiency
3|Page
, Which of the following best describes the RT response to metabolic alkalemia? - - ANS✔️---
metabolic alkalemia depresses the respiratory center, causing hypoventilation
The RT has just suctioned blue, creamy secretions from a pt with a tracheostomy that wears the
mask intermittent tube feedings. Which of the following actions would be appropriate? - -
ANS✔️---check the integrity of the tracheostomy cuff
8 During a CPAP titration during sleep procedure, the pt becomes agitated and refuses to
continue to wear the mask when the CPAP is increased from 15 cm H2O ro 16 cm H2O. The
previous setting of 15 cm H2O, the pt continued to have obstructive respiratory events. Which of
the following should be done? - - ANS✔️---switch to BiPAP titration
Which of the following are potential complications that might occur as a result of an under
inflated endotracheal tube's cuff?
1 Tracheomalacia- YES Tracheostenosis- YES Gastric Insufflation- YES Aspiration-NO
2 Tracheomalacia- NO Tracheostenosis- NO Gastric Insufflation- YES Aspiration-YES
3 Tracheomalacia- NO Tracheostenosis- NO Gastric Insufflation- NO Aspiration- YES
4 Tracheomalacia- YES Tracheostenosis- YES Gastric Insufflation- NO Aspiration- YES - -
ANS✔️--2 Tracheomalacia- NO Tracheostenosis- NO Gastric Insufflation- YES Aspiration-YES
Prior to taking a pulmonary artery wedge pressure (PCWP) reading, the RT ensure that: - -
ANS✔️---the transducer is properly leveled and zeroed
