A client with 50% full-thickness burns has received fluid resuscitation for the past 24 hours. Which assessment warrants immediate intervention by the nurse?

The correct answer is: c. Inspiratory and expiratory bilateral crackles. Choice A: Average urine output of 28 mL/hour Reason: The normal urine output for an adult is typically 0.5 mL/kg/hr, which translates to about 30-50 mL/hr for most adults. An average urine output of 28 mL/hour is slightly below this range, indicating possible inadequate fluid resuscitation. However, it is not immediately life-threatening and does not warrant the most urgent intervention compared to other options. Choice B: Vesicular bibasilar breath sounds Reason: Vesicular breath sounds are normal lung sounds heard over most of the lung fields. They are soft and low-pitched, indicating that the airways are clear. Therefore, vesicular bibasilar breath sounds do not indicate any immediate respiratory distress or fluid overload and do not require urgent intervention. Choice C: Inspiratory and expiratory bilateral crackles Reason: Crackles, also known as rales, are abnormal lung sounds that indicate the presence of fluid in the alveoli. Bilateral crackles heard during both inspiration and expiration suggest significant pulmonary edema or acute respiratory distress syndrome (ARDS), which can be life-threatening and requires immediate intervention. Choice D: Central venous pressure of 12 mm Hg Reason: The normal range for central venous pressure (CVP) is 2-8 mm Hg. A CVP of 12 mm Hg is elevated, indicating possible fluid overload or heart failure. While this is concerning and requires monitoring, it is not as immediately critical as bilateral crackles, which directly affect oxygenation and respiratory function.
