Oxygenation and Ventilation Quiz

What is the primary function of a mechanical ventilator?

• To deliver warmed and humidified air to the lungs

• To provide supplemental oxygen

• To assist with medication delivery

• To monitor blood pressure

Which type of mask can deliver 40% to 60% oxygen concentration?

• Nasal cannula

• Simple face mask

• Non-rebreather mask

• Venturi mask

What is a key advantage of using a nasal cannula?

• It is effective for mouth breathers

• It allows patients to talk and eat

• It provides high oxygen concentration

• It is suitable for all patients

What is the purpose of weaning off a ventilator?

• To restore spontaneous breathing

• To provide medication

• To increase oxygen levels

• To monitor respiratory rate

Which of the following is an indication for mechanical ventilation?

• Stable respiratory condition

• Routine oxygen therapy

• Hypoxemia despite maximum oxygen therapy

• Mild respiratory distress

What does the term 'FiO2' refer to?

• Forced inspiratory pressure

• Flow rate of oxygen

• Frequency of inhalation

• Fraction of inspired oxygen

Which type of ventilation allows the patient to breathe independently?

• Synchronized Intermittent Mandatory Ventilation

• Pressure support ventilation

• Assist-control ventilation

• Controlled Mandatory Ventilation

What is a disadvantage of using a non-rebreather mask?

• It is easy to use

• It can cause suffocation if gas flow is interrupted

• It provides low oxygen concentration

• It is suitable for long-term use

What is the primary goal of suctioning an artificial airway?

• To monitor blood pressure

• To provide medication

• To maintain a patent airway

• To increase oxygen levels

Which of the following is a type of non-invasive positive pressure ventilation?

• CPAP

• Partial re-breather mask

• Simple face mask

• Non-rebreather mask
