Final answer:
The scenario of Cheryl using an electronic device to transmit her blood pressure readings to a nurse indicates the use of telehealth, which enables her to avoid frequent doctor visits.
Step-by-step explanation:
The scenario you've provided indicates the use of telehealth technology. Telehealth is the broader application of telecommunications in healthcare, including a range of services beyond clinical care such as education and monitoring. Cheryl's use of an electronic blood pressure cuff to transmit her daily blood pressures to a nurse is a perfect example of telehealth.
She remotely sends her data via a telephone connection, and the nurse reviews the information and provides her with the necessary advice. This allows Cheryl to avoid frequent trips to the doctor's office for blood pressure monitoring, which is particularly beneficial given her mobility problems.
