Question 1:

A nurse is providing oxygen therapy to a client with chronic obstructive pulmonary disease (COPD). Which oxygen delivery system would be most appropriate for this client?

A. Nasal cannula B. Venturi mask C. Non-rebreather mask D. Oxygen tent

Answer and Explanation

Choice A:

Nasal cannula delivers a lower oxygen concentration and may not provide sufficient oxygen for clients with severe COPD.

Choice B:

The Venturi mask is the most appropriate oxygen delivery system for clients with COPD as it provides a precise and controlled oxygen concentration. This system allows for a specific amount of room air to mix with oxygen, ensuring a precise oxygen level is delivered without the risk of excessive oxygen concentration.

Choice C:

Non-rebreather mask delivers a high concentration of oxygen, which can potentially worsen the client's condition by reducing respiratory drive.

Choice D:

Oxygen tent is not commonly used in COPD management and is typically reserved for pediatric clients or those with specific respiratory conditions.

Question 2:

A client with pneumonia requires oxygen therapy. Which oxygen delivery system would be most appropriate for this client to improve oxygenation and reduce the work of breathing?

A. Simple face mask B. Partial rebreather mask C. High-flow nasal cannula D. Transtracheal catheter

Answer and Explanation

Choice A:

Simple face mask does not provide precise oxygen concentrations and may not be as effective in improving oxygenation as other options.

Choice B:

Partial rebreather mask is not typically used in pneumonia management as it may impede effective coughing and clearance of secretions.

Choice C:

High-flow nasal cannula delivers a high flow rate of humidified oxygen and provides consistent oxygenation while reducing the work of breathing. It is effective in improving oxygenation in clients with pneumonia.

Choice D:

Transtracheal catheter is a more invasive oxygen delivery method and is not commonly used in pneumonia management.

Question 3:

A client with acute respiratory distress syndrome (ARDS) requires high levels of positive end-expiratory pressure (PEEP). Which oxygen delivery system would be most effective in providing the necessary PEEP?

A. Non-rebreather mask B. Venturi mask C. Continuous positive airway pressure (CPAP) mask D. Bag-valve-mask (BVM) device

Answer and Explanation

Choice A:

Non-rebreather mask does not provide positive pressure and is not the appropriate choice for delivering PEEP.

Choice B:

Venturi mask is not designed to provide PEEP.

Choice C:

Continuous positive airway pressure (CPAP) mask Explanation: CPAP mask provides positive pressure throughout the respiratory cycle, including expiration, and is effective in delivering the necessary PEEP in clients with ARDS.

Choice D:

Bag-valve-mask device is typically used for manual ventilation and resuscitation, not for delivering continuous positive pressure.

Question 4:

A nurse is caring for a client with severe hypoxemia and requires precise oxygen titration. Which oxygen delivery system would be most appropriate for this client?

A. Simple face mask B. Non-rebreather mask C. Partial rebreather mask D. High-flow nasal cannula

Answer and Explanation

Choice A:

Simple facemask do not provide precise control over oxygen concentrations and may not be as effective in delivering accurate oxygenation in severe hypoxemia.

Choice B:

Non-rebreather maskdo not provide precise control over oxygen concentrations and may not be as effective in delivering accurate oxygenation in severe hypoxemia.

Choice C:

Partial rebreather mask do not provide precise control over oxygen concentrations and may not be as effective in delivering accurate oxygenation in severe hypoxemia.

Choice D:

High-flow nasal cannula is effective in delivering precise oxygen concentrations and provides consistent oxygenation for clients with severe hypoxemia.

Question 5:

A client with sleep apnea requires positive pressure ventilation duringsleep. Which oxygen delivery system would be most appropriate for this client to ensure continuous positive airway pressure (CPAP)?

A. Nasal cannula B. Venturi mask C. Non-rebreather mask D. CPAP mask

Answer and Explanation

Choice A:

Nasal cannula does not provide positive pressure ventilation and is not suitable for addressing sleep apnea.

Choice B:

Venturi mask is not designed to deliver positive pressure ventilation and are not commonly used for sleep apnea management.

Choice C:

Non-rebreather mask are not designed to deliver positive pressure ventilation and are not commonly used for sleep apnea management.

Choice D:

CPAP mask Explanation: A CPAP mask is the most appropriate oxygen delivery system for a client with sleep apnea who requires positive pressure ventilation. It delivers a continuous flow of air or oxygen at a constant pressure to keep the airway open during sleep.
