A nurse is caring for a client who has burns to approximately 50% of their body. Which of the following physiological changes related to the burns should the nurse anticipate? Select all that apply.
Explanation & Rationale
A. Hypermagnesemia: Hypermagnesemia is not typically seen in burn patients. More commonly, patients may experience imbalances in electrolytes such as sodium or potassium. Hypermagnesemia is not directly associated with burns or their complications. B. Capillary leak: In the immediate aftermath of a severe burn, the damage to the capillaries leads to a capillary leak, where plasma, proteins, and electrolytes seep out of the vessels and into the interstitial space. This results in edema and a significant reduction in circulating blood volume. C. Loss of protein: Burn injuries, especially those affecting a large body surface area, cause significant loss of proteins (mainly albumin) due to the breakdown of the skin and increased capillary permeability. This loss of protein contributes to the development of edema and hypovolemic shock. D. Diuresis: Diuresis does not typically occur in the immediate post-burn period. During the first 24-48 hours, oliguriaoccurs due to hypovolemia and kidney perfusion problems. Diuresis occurs after fluid resuscitation has been successful and fluid begins to shift back from the interstitial space into the vascular system. E. Decreased plasma volume: A reduction in plasma volume is a critical concern in burn patients due to fluid and protein loss from the damaged blood vessels. This leads to hypovolemia, which requires aggressive fluid resuscitation to prevent shock and organ failure.
