A nurse is providing education regarding oral antibiotics to the family of a child with infectious endocarditis. Which of the following statements by the client's caregivers indicates an understanding of the education?

A. Completing the full course of antibiotics is essential in treating infectious endocarditis because incomplete therapy can lead to persistent infection, bacterial resistance, or relapse. Even if the child feels well, bacteria may still be present, and stopping early can compromise treatment efficacy. B. While children with certain heart conditions may require prophylactic antibiotics before dental or invasive procedures, infectious endocarditis requires daily prescribed antibiotics for the duration specified to fully eradicate the infection. C. Fever resolution does not indicate that the infection is completely cleared. Stopping antibiotics prematurely increases the risk of relapse and development of antibiotic-resistant bacteria. D. Although the current infection may be resolved, children with underlying heart conditions or structural heart defects may still be at risk for future endocarditis. Prophylactic measures may be necessary for future procedures, so ongoing vigilance is required.
