What clinical evaluations need to be assessed by the registered respiratory therapist to determine whether the peak inspiratory pressure has been set adequately in an infant who has respiratory distress syndrome
I.Exhaled tidal volume is greater than 3 mL/kg and less than 8 mL/kg.
II.pH is 7.25 to 7.35 with PaCO₂ of 45 to 55 mm Hg.
III.pH is 7.45 with PaCO₂ of 50 mm Hg.

The exhaled tidal volume (I) should be assessed to ensure that the peak inspiratory pressure is not too high, which can cause lung injury in infants. Additionally, the pH and PaCO₂ levels (II) should be evaluated to ensure that the peak inspiratory pressure is not too low, which can cause inadequate ventilation and respiratory acidosis. Option III can be ruled out as a correct answer as a pH of 7.45 is not typical in respiratory distress syndrome; a pH of 7.25 to 7.35 would be expected. Therefore, options I and II are the best choices.
