She’s having moderately p 40-second contractions every 5 minutes. She seems rather anxious and becomes very tense during each contraction. When the client asks for pain relief, what should the nurse do next

A. Determine the source of her anxiety and institute interventions to help her relax.
B. Immediately check the physician’s order and give her the analgesic ordered.

关节尿酸炎是一种罕见的严重关节疾病。一种传统的观点认为，这种疾病曾于2500年前在古埃及流行，其根据是在所发现的那个时代的古埃及木乃伊中，有相当高的比例可以发现患有这种疾病的痕迹。但是，最近对于上述木乃伊骨骼的化学分析使科学家们推测，木乃伊所显示的关节损害实际上是对尸体亓行防腐处理时所使用的化学物质引起的。 以下哪项如果为真，最能进一步加强对题干中所提及的传统观点的质疑( )

A．在我国西部所发现的木乃伊中，同样可以发现患有关节尿酸炎的痕迹

B．关节尿酸炎是一种遗传性疾病，但在古埃及人的后代中这种病的发病率并不比一般的要高

C．对尸体进行成功的防腐处理，是古埃及人一项密不宣人的技术，科学家至今很难确定他们所使用物质的化学性质

D．在古代中东文物艺术品的人物造型中，可以发现当时的人患有关节尿酸炎的参考证据
