Rationale: The needs assessment is a crucial phase of the life cycle. This phase is ongoing and systematic.

Answer to Question 2

4
Rationale: Clients may stay within their own community to be assessed and treated, lowering potential costs. Access to care is typically improved, with time and travel savings for the client. Nurse practitioner services may actually be extended because of physician availability as resources. Clients may or may not have equipment at home with which they may transmit information; but access to care would not be delayed just because the equipment had not yet been delivered.
