Burns and Burn Injury Q 91

---

Which finding indicates that fluid resuscitation has been successful for a client with a burn injury?

  

    A. Hematocrit = 60%

    B. Heart rate = 130 beats/min

    C. Increased peripheral edema

    D. Urine output = 50 mL/hr

    

    

Correct Answer: D. Urine output = 50 mL/hr

The fluid remobilization phase improves renal blood flow, increases diuresis, and restores blood pressure and heart rate to more normal levels, as well as laboratory values. This phase occurs on days 1-3 and requires an accurate fluid resuscitation and thorough evaluation for other injuries and comorbid conditions.

Option A: Hematocrit can indirectly reflect the resuscitation effect in the burn shock stage. Whether hematocrit level can be lowered to 0.45-0.50 during the first 24 hours after burn may be an important index for evaluation of fluid resuscitation effect in the early shock stage after severe burn.

Option B: The average daily heart rate was elevated in burn patients up to two years post-burn. Heart rate was elevated despite any afforded resuscitative efforts. While research data are up to two years post-injury, the heart rate of severely burned children was still 120% of predicted compared to normal values for children.

Option C: Swelling tends to occur soon after injury and generally decreases after 48–72 hours, although this timescale can vary. The extent and location of the swelling will depend on how the burn was caused and the location and depth of the burn injury. It is very important that the swelling is reduced as soon as possible.
