1. What is the purpose of setting the inspiratory pressure on a ventilator?

A. To control the volume of air delivered to the patient

B. To control the rate of breaths delivered to the patient

C. To control the amount of pressure delivered to the patient during

inhalation

D. To control the amount of oxygen delivered to the patient

Answer: C. To control the amount of pressure delivered to the patient

during inhalation

Rationale: Setting the inspiratory pressure on a ventilator allows for

control over the amount of pressure delivered to the patient during

inhalation, which can help improve oxygenation and lung compliance.

2. What is the purpose of setting the PEEP (positive end-expiratory

pressure) on a ventilator?

A. To prevent lung collapse

B. To control the rate of breaths delivered to the patient

C. To increase the amount of oxygen delivered to the patient

D. To control the volume of air delivered to the patient

Answer: A. To prevent lung collapse

Rationale: PEEP is used to prevent alveolar collapse during expiration,

improve oxygenation, and maintain lung compliance. It helps keep the

airways open and increases the functional residual capacity of the lungs.

3. What do the settings of the FiO2 control on a ventilator?

A. The rate of breaths delivered to the patient

B. The amount of pressure delivered to the patient during inhalation

C. The volume of air delivered to the patient

D. The percentage of oxygen delivered to the patient

Answer: D. The percentage of oxygen delivered to the patient

Rationale: FiO2 refers to the fraction of inspired oxygen and controls the

percentage of oxygen delivered to the patient during ventilation. It is used

to adjust oxygen levels based on the patient's needs.

4. How does adjusting the tidal volume setting on a ventilator affect the

patient?
