The nursing care plan for the client with dehydration includes interventions for oral health. Which intervention is outside the scope of practice for an LPN/LVN being supervised by a nurse?

• A. Reminding the client to avoid commercial mouthwashes
• B. Encouraging mouth rinsing with warm saline
• C. Observing the lips, tongue, and mucous membranes
• D. Initiating a dietary consult to increase fluids on meal trays

Answer: (D)

The key idea here is understanding what tasks an LPN/LVN can perform under supervision versus what requires a nurse or licensed provider to initiate. For dehydration with a focus on oral health, the hands-on, noninvasive tasks that involve education, monitoring, and simple care are within the LPN/LVN role when supervised. Reminding the client to avoid commercial mouthwashes and encouraging mouth rinsing with warm saline are teachable, routine actions that promote comfort and maintain oral moisture. They involve patient education and simple guidance, which the LPN/LVN can do under the supervising nurse’s direction. Observing the lips, tongue, and mucous membranes is also within scope as part of ongoing assessment; the LPN/LVN can monitor for signs of dryness or dehydration and report findings promptly.

Initiating a dietary consult to increase fluids on meal trays, however, goes beyond the LPN/LVN scope. This requires professional judgment to modify the care plan and arranging or initiating an interdisciplinary referral, which typically is the responsibility of the supervising nurse or the provider. The LPN/LVN can document the assessment and request the consult through the nurse, but they should not independently initiate the consult or alter the care plan.

So, while oral hygiene reminders, saline rinses, and visual assessment of the oral cavity are appropriate tasks for an LPN/LVN under supervision, starting a dietary consult to increase fluids is outside their scope of practice.
