A mother brings her 5-month-old female child to the pediatric clinic. The child has had recurrent middle-ear infections since she was 3 months old. Which of the following areas is most important to assess ？（）
A．How well the client eats.
B．The client's weight gain since her last visit.
C．Whether the client received all of her prescribed antibiotic at the time of the last infection.
D．The client's temperature.
参考答案：C
解析：
If the client isn't receiving her full course of antibiotic therapy, her ear infections will recur; permanent hearing loss or systemic infection may result. Parents may not understand this and may discontinue treatment when the neonate seems better. The other options are important aspects to assess, but none is as critical as ensuring full compliance with antibiotic therapy.
