Final answer:
Increase the flow rate of oxygen when using a Non-Rebreather Mask (NRB) if the reservoir bag collapses fully with each breath to ensure a constant and sufficient supply of oxygen for the patient. Option 1 is correct.
Step-by-step explanation:
If your patient is on a Non-Rebreather Mask (NRB) at 12 liters per minute (lpm) and the reservoir bag fully collapses with each breath the patient takes, you should increase the flow rate of oxygen. This is necessary to ensure that the bag remains at least partially inflated at all times, providing a reservoir of oxygen to deliver high concentrations of oxygen during each breath. If the bag continues to collapse, it suggests that the demand for oxygen is exceeding the supply, and the patient is not receiving the intended oxygen concentration.
Option 1 is the correct action to take: Increase the flow rate of oxygen. By doing so, you will create a sufficient reserve of oxygen in the reservoir to meet the patient's inspiratory flow needs, thus preventing the bag from collapsing fully when the patient inhales.
