Final answer:
Telehealth is utilized by a community health nurse to improve access to care in rural areas and provides nursing care to clients in their homes. Telehealth also substitutes face-to-face care for those who cannot afford it.
Step-by-step explanation:
The rationale for the use of telehealth by a community health nurse is to improve access to care in rural areas. Telehealth allows clients to receive nursing care in their homes, eliminating the need for them to travel long distances to access healthcare facilities.
