Which patient assignment is most suitable for an LPN/LVN?

The most suitable patient assignment for an LPN/LVN is the adolescent with dehydration who is taking fluids well by mouth. LPNs/LVNs are trained to provide basic patient care and can effectively monitor and assist patients who are stable and require routine care.

In this case, the adolescent with dehydration is in a manageable condition since they are able to take fluids orally, indicating a level of stability that allows for care within the LPN/LVN scope of practice. They can perform assessments, provide education about hydration, and help with ongoing monitoring of the adolescent's condition.

The other options involve patient situations that require a higher level of nursing expertise or more complex interventions. The elderly patient with complex medication needs may require extensive medication management and assessment that are typically within the RN’s scope. The new patient with multiple health concerns may need comprehensive evaluations and interventions that an LPN/LVN is not primarily responsible for yet. Finally, the severely ill patient requiring close monitoring would not be suitable for an LPN/LVN, as it demands constant assessment and critical thinking that typically fall under the responsibility of registered nurses. Thus, the choice of the adolescent who is stable and managing hydration independently is the most appropriate for an LPN/LVN.
