It is decided that this patient requires intubation and mechanical ventilation. The most appropriate ventilator settings for this patient include which of the following?

A 5’10” male patient with normal lungs has been intubated and requires mechanical ventilation with volume-controlled continuous mandatory ventilation (VC-CMV). The tidal volume and ventilator rate settings that should be recommended for this patient are which of the following?                                                                     2:6:11

When a patient is to be switched from continuous mandatory ventilation (CMV) to synchronized intermittent mandatory ventilation (SIMV) to facilitate weaning from mechanical ventilation, which of the following could be used in addition to SIMV to assist this process?                                                        2:5:1

A ventilator is set to deliver a 600 mL tidal volume. The flow rate is set at 40 L/min and the frequency is set at 10 breaths/min. If the flow rate is doubled and the patient is not assisting, which of the following will occur?                                                    2:6:7

The condition that is associated with an increase in airway resistance is which of the following?                                                                                           1:1:5
