In an industrial accident, a client who weighs 155 lb (70.3 kg) sustained full-thickness burns over 40% of his body. He's in the burn unit receiving fluid resuscitation. Which observation shows that the fluid resuscitation is benefiting the client
A．A urine output consistently above 100 mL/hr.
B．A weight gain of 4 lb (1.8 kg) in 24 hours.
C．Body temperature readings all within normal limits.
D．An electrocardiogram (ECG) showing no arrhythmias.
参考答案：A
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.
