Hesi lpn exit proctored exam
The practical nurse (PN) learns in report that a client has a prescription for continuous humidified oxygen at 4 L/minute via a nasal cannula. Upon entering the client's room, the PN observes that the oxygen flow rate is set at 1 L/minute, there is no water in the humidifier, and there are reddened areas on the client's ears under the cannula tubing. The client has a respiratory rate of 22 breaths/minute and has dry and cracked mucous membranes. Which action should the PN take first?
Explanation & Rationale
A. Add distilled water to the humidifier: Necessary for moisture, but oxygen delivery must be corrected first. B. Place padding over reddened area: Helps prevent skin breakdown but does not address oxygen needs. C. Increase the oxygen flow rate: Priority is to restore prescribed oxygen to prevent hypoxia. D. Instruct client to increase fluid intake: Can help with dryness but is not urgent compared to correcting oxygen flow.
