The nurse is taking care of a burn patient with deep partial-thickness burns. Which of the following factors can contribute to fluid imbalance in burn patients?
Decreased metabolic rate
Increased capillary permeability
Normal electrolyte levels
Excessive fluid intake
The Correct Answer is B
A. Decreased metabolic rate:
Burns cause an increase, not decrease, in metabolic rate due to the hypermetabolic state post-injury.
B. Increased capillary permeability:
This is a hallmark of burn injuries. Damaged capillaries leak fluid into interstitial spaces, leading to fluid and electrolyte imbalance.
C. Normal electrolyte levels:
Electrolyte levels are often abnormal in burn patients due to fluid shifts and tissue damage.
D. Excessive fluid intake:
Overhydration can be harmful, but it is not a typical cause of the initial fluid imbalance seen in burns.

Correct Answer is D
Explanation
A. To prevent infection in burn wounds:
Analgesics like Dilaudid do not prevent infection; antibiotics and wound care do.
B. To promote wound healing in burn patients:
Pain control may aid indirectly, but opioids do not promote wound healing directly.
C. To decrease the risk of hypothermia in burn patients:
Hypothermia prevention involves warm blankets, warming devices, and fluid management-not PCA.
D. To provide controlled and individualized pain relief in burn patients:
PCA pumps allow patients to self-administer opioid analgesia, offering consistent, effective pain control with less risk of overdose when properly programmed.
