Final answer:
Home healthcare is the best option for a home-bound client needing long-term intravenous antibiotic therapy as it provides necessary in-person medical care in the patient's home.
Step-by-step explanation:
The best service to meet the needs of a home-bound client requiring long-term intravenous antibiotic therapy, according to the options provided, would be C. Home healthcare. This type of service enables patients to receive professional medical care, such as the administration of IV antibiotics, in the comfort of their own homes. Home healthcare professionals can handle the antibiotic regimen and monitor the patient's progress. In contrast, hospice is designed for terminally ill patients, respite care is for short-term relief for caregivers, and telehealth does not provide in-person treatment necessary for intravenous therapy.
For the administration of an antimicrobial to treat a systemic infection at home, the appropriate and convenient routes would include A. oral and D. parenteral, which includes intravenous methods. However, since the home-bound client requires an intravenous approach, the correct answer would be B. intravenous, assuming that the oral route is not appropriate or effective for their condition.
