Medical Surgical Carbon monoxide poisoning #2

Question

A client is brought in for carbon monoxide poisoning. Which mask is most clinically indicated?

Answers

  1. Nasal cannula
    • Rationale:

      This answer is not correct because a nasal cannula mask is used when the client only requires small amounts of supplemental oxygen. They are used for short-term or long-term use, only delivering an oxygen concentration of 28% to 44%.

  2. Face tent
    • Rationale:

      This answer is not correct because the face tent mask is used in the event of facial trauma. It provides high humidification for facial burns and is preferred in clients who are claustrophobic.

  3. Non-rebreather
    • Rationale:

      This answer is correct because a non rebreather mask is used to facilitate more oxygen inhalation during inspiration. Non rebreather masks are used during a medical emergency because they deliver 10-15 liters of oxygen and help eliminate the carbon dioxide. The bag has to be more than halfway full to ensure adequate ventilation. Flutter valve needs to stay closed to help more oxygen get in during inhalation.

  4. Venturi mask
    • Rationale:

      This answer is not correct because the Venturi mask is used when precise oxygen delivery is required. This is typically used in clients with unstable COPD.

Overview

The client being treated for carbon monoxide poisoning has high carbon dioxide levels and requires more oxygen. A non rebreather mask is used to facilitate more oxygen inhalation during inspiration.

Explanation

Learning Outcomes

Carbon monoxide poisoning is treated with administration of oxygen. Carbon monoxide increases carbon dioxide levels. A non rebreather mask is used to facilitate more oxygen inhalation during inspiration. Non rebreather masks are used during a medical emergency because they deliver 10-15 liters of oxygen and help eliminate the carbon dioxide. The bag has to be more than halfway full to ensure adequate ventilation. The flutter valve needs to stay closed to help more oxygen get in during inhalation. Tightening the facemask straps will help prevent leaks. The non rebreather helps eliminate the CO2 and treat the hypoxia.

Test Taking Tip

If you know how carbon monoxide is treated, you will know which mask is required.
