C. A service is not considered a skilled nursing service merely because it is performed by, or under the direct supervision of, a licensed nurse

When services can be safely and effectively performed (or self-administered) by the average, non-medical person without the direct supervision of a licensed nurse, the services cannot be regarded as a skilled nursing service. For example, the giving of a bath does not generally require the skills of a nurse. Consequently, it does not constitute a skilled nursing service even though it is performed by a nurse.
