Nursing interventions and care ( 5 Questions)
A nurse is providing oxygen therapy to a client who had a prolonged and obstructed labor and is experiencing respiratory distress.
Which of the following oxygen delivery devices should the nurse use to provide the highest concentration of oxygen?
a nasal cannula delivers low concentrations of oxygen (24-30% O2) and is used for mild hypoxia. A nasal cannula can also cause dryness and irritation of the nasal passages at high flows.
a simple face mask delivers moderate concentrations of oxygen (30-40% O2) and is used for mild to moderate hypoxia. A simple face mask does not allow close control of FiO2 and has a risk of aspiration if the client vomits.
This is because a non-rebreather mask can deliver high concentrations of oxygen (approximately 70% O2) to a client who is experiencing respiratory distress. A non-rebreather mask has a reservoir bag that fills with oxygen and a valve that prevents the exhaled air from mixing with the oxygen in the bag.
a venturi mask delivers precise concentrations of oxygen (24-60% O2) and is used for clients who need specific FiO2. A venturi mask has color-coded valves that adjust the amount of air entrainment. A venturi mask is not suitable for clients who need high concentrations of oxygen or who have variable respiratory rates and tidal volumes.
This is because a non-rebreather mask can deliver high concentrations of oxygen (approximately 70% O2) to a client who is experiencing respiratory distress. A non-rebreather mask has a reservoir bag that fills with oxygen and a valve that prevents the exhaled air from mixing with the oxygen in the bag.
