问题单项选择题

A client is receiving an IV infusion of dextrose 5% in water and lactated Ringer's solution at 125 mL/hr to treat a fluid volume deficit. Which of these signs indicates a need for additional IV fluids

A．Serum sodium level of 125 mEq/L.

B．Temperature of 99.6 °F(37.6℃).

C．Neck vein distention.

D．Dark amber urine.

答案

参考答案：D

解析：Normally, urine appears light yellow; dark amber urine is concentrated and, in this client, suggests continued fluid volume deficit. The serum sodium level normally ranges from 135 to 145 mEq/L. A temperature of 99.6°F is only slightly elevated and doesn't indicate fluid volume deficit. Neck vein distention is a sign of fluid volume overload.
