Final answer:
A correct statement by the parents would demonstrate an understanding of the importance of following the prescription instructions for amoxicillin and clavulanate potassium fully, to combat their child's bilateral otitis media effectively and prevent antibiotic resistance.
Step-by-step explanation:
A statement by the parents that indicates effective education about the prescribed medication amoxicillin and clavulanate potassium for their 18-month-old infant's bilateral otitis media might be, "We understand that it's important to give our child the antibiotic exactly as prescribed, even if the symptoms improve before completing the course, to ensure all the bacteria are killed and prevent antibiotic resistance." This reflects an understanding of the importance of completing antibiotic courses, a key concept in preventing the development of antibiotic-resistant bacteria. It also shows comprehension of the treatment plan for acute otitis media (AOM), which is consistent with what health professionals encourage.
