参考答案: A

参考解析: In a client with burns, the goal of fluid resuscitation is to maintain a mean arterial blood pressure that provides adequate perfusion of vital structures. If the kidneys are adequately perfused, they will produce an acceptable urine output of at least 0.5 mL/(kg hr). Thus, the expected urine output of a 155 lb client is 35 mL/hr, and a urine output consistently above 100 mL/hr is more than adequate. Weight gain from fluid resuscitation isn't a goal. In fact, a 4 lb weight gain in 24 hours suggests third spacing. Body temperature readings and ECG interpretations may demonstrate secondary benefits of fluid resuscitation but aren't primary indicators.
