Final answer:
The ability for an LPN to perform oral health screenings and apply fluoride varnish depends on state regulations and requires specific training. Generally, LPNs can perform these tasks under appropriate supervision.
Step-by-step explanation:
Whether a licensed practical nurse (LPN) can perform oral health screenings and apply fluoride varnish depends on the regulations set forth by the state's Board of Nursing and dental practice acts. In many cases, LPNs are allowed to carry out these tasks under the supervision of a dentist or a registered nurse, as part of a broader oral health program. However, to perform these duties, LPNs are typically required to complete specific training regarding oral health assessments and the application of fluoride varnish.
In summary, the answer to your question may vary depending on the region, but generally speaking, yes, LPNs can perform oral health screenings and apply fluoride varnish given they have the appropriate training and are operating within the scope of their state's regulations.
