Which of the following conditions may require higher  respiratory rates? I. Metabolic alkalosisII. ARDSIII. Increased intracranial pressureIV. Metabolic acidosis

The patient has a back up rate of 20 breaths/min with a 1 second I:time on pressure control ventilation. What is the patient’s I:E ratio?

A patient is on a ventilator with a rate of 15 breaths per minute and an inspiratory time of 1 second. What is the total cycle time for each breath?      

Your patient’s clinical status abruptly changed and unstable, the alarms on the ventilator are triggered. What is/are the first step(s) you should take?

An adult male patient is on CMV intubated with a 8.5 endotracheal tube (ETT). What size suction catheter should the respiratory therapist select to decrease the risk of hypoxemia during suctioning?

A homeless patient was brought in with a temperature of 29oc breathing slow and shallow with a moderately low blood pressure. This patient is:

A 5′ 6″ female patient was admitted for COPD exacerbation secondary to pneumonia. When the practitioner arrived to assess her and was found to be obtunded with slow shallow respirations. The following arterial blood gas was obtained on a NRB:   pH – 7.22 PaCO2 – 70 torr PaO2 – 68 torr HCO3 – 30 mEq/L     The physician decided to intubate. What initial vent settings should the patient be placed on?

An 80-kg (176-lb) patient is being ventilated in pressure control mode. During a ventilator check, the therapist notes that the compliance has increased from 35 mL/cm H2O to 50 mL/cm H2O. What effect will this change in compliance have on volume?

If the high pressure alarm and low tidal volume alarm goes off on the vent, which of the following should you consider: I. Pneumothorax II. Bronchospasm III. Leak in the circuit IV. Biting the ETT
