A nurse is planning care for a client who is to be discharged with home oxygen. Which of the following information should the nurse include in the plan of care?

Rationale: A. Humidification is not routinely required for low-flow oxygen therapy (typically ≤ 4 L/min via nasal cannula). It is generally considered when oxygen is delivered at higher flow rates or when the client experiences dryness or thick secretions. Routine humidification at low flow is not necessary. B. Oxygen tanks should never be secured to a bed because beds are movable. If the bed is moved, the unsecured tank could fall or become damaged, creating a safety hazard. Oxygen cylinders should be secured in a stable, upright position using a proper stand or holder. C. Petroleum-based products are flammable and should never be used with oxygen therapy due to the increased risk of combustion. Water-soluble lubricants should be used instead to reduce dryness of the nasal mucosa. D. Clients on home oxygen therapy should be taught to monitor the oxygen cylinder gauge regularly (often daily) to ensure an adequate supply and to prevent unexpected depletion. This is an important safety measure for continuous oxygen availability.
