单项选择题
The nurse noticed that an 8-month-old child's posterior fontanel is slightly open. Which of the following should the nurse do next
A．Check the child's head circumference.
B．Question the mother about the child's delivery.
C．Schedule an X-ray of the child's head.
D．Document this as a normal finding.
答案
参考答案：A
解析：The posterior fontanel usually closes by age 2 to 3 months. Therefore, the nurse should measure the head circumference to determine if the child's head is larger than the established norms because hydrocephalus can cause separation of the cranium sutures.
