Final answer:
The inappropriate liter flow for oxygen administration via a nasal cannula is 7-8 liters/minute, as typical nasal cannula flow rates are between 1-6 liters/minute.
Step-by-step explanation:
The inappropriate liter flow for oxygen administration via a nasal cannula is 7-8 liters/minute. The typical flow range for a nasal cannula is 1-6 liters per minute. When the flow rate is higher than 6 liters per minute, it can cause discomfort and drying of the nasal passages. Oxygen administration at 7-8 liters/minute is better suited for delivery devices that can provide higher oxygen concentrations, such as a simple face mask or a non-rebreather mask. When using a nasal cannula, the recommended flow rates are indeed between 1-2 liters/minute (for mild hypoxemia), 3-6 liters/minute (for more significant hypoxemia). Therefore, option d) 7-8 liters/minute is incorrect for a nasal cannula.
