单选题 Which statement about fluid replacement is accurate for a client with hyperosmolar hyperglycemic nonketotic syndrome (HHNS) ?
A. Administer 2 to 3 L of IV fluid rapidly.
B. Administer 6 L of IV fluid over the first 24 hours.
C. Administer a dextrose solution containing normal saline solution.
D. Administer IV fluid slowly to prevent circulatory overload and collapse.

【正确答案】 A

【答案解析】Regardless of the client's medical history, rapid fluid resuscitation is critical for maintaining cardiovascular integrity. Profound intravascular depletion requires aggressive fluid replacement. A typical fluid resuscitation protocol is 6 L of fluid over the first 12 hours, with more fluid to follow over the next 24 hours. Various fluids can be used, depending on the degree of hypovolemia. Commonly prescribed fluids include dextran (in cases of hypovolemic shock), isotonic normal saline solution and, when the client is stabilized, hypotonic half-normal saline solution.
