Final answer:
The respiratory therapist should recommend a PEEP level of 17 cm H2O. Hence the correct answer is option B
Step-by-step explanation:
The respiratory therapist should recommend a PEEP level of 17 cm H2O. PEEP stands for Positive End-Expiratory Pressure, and it is used to keep the airways open and prevent alveolar collapse during mechanical ventilation. By applying a constant pressure at the end of exhalation, PEEP improves oxygenation and promotes better lung recruitment.
Hence the correct answer is option B
