A client with extensive burns is receiving intravenous fluids to replace fluid loss. The nurse would monitor for which initial symptom of fluid overload?

• A. Crackles in the lungs
• B. Decreased heart rate
• C. Decreased blood pressure
• D. Cyanosis of nailbeds

Answer: (A)

When monitoring fluid management in burn resuscitation, the first sign that you’re reinforcing the system with too much fluid is crackles heard in the lungs. Those crackles reflect fluid accumulating in the interstitial and alveolar spaces, i.e., pulmonary edema, which can begin with excessive IV fluids even before other symptoms become apparent. The lungs are typically the first place fluid overload shows up because the extra volume shifts into the pulmonary vasculature and interstitium. Other signs are less likely to appear first. A decreased heart rate isn’t characteristic of fluid overload (the heart often compensates with a faster rate). Decreased blood pressure points toward under-resuscitation or shock, not overload. Cyanosis of the nailbeds indicates significant hypoxemia and is a later or more severe sign rather than the initial indicator of fluid excess. So crackles in the lungs are the best early clue that fluid overload is developing during burn fluid resuscitation, prompting adjustment of fluid administration and close respiratory monitoring.
