A client receiving treatment for severe burns over more than half of his body has an indwelling urinary catheter inserted. When evaluating the client's intake and output, which of the following should be taken into consideration? The amount of urine:

A.

is expected to be decreased for three to five days.

B.

will be reduced in the first 24-48 hours and will then increase.

C.

output will be greatest in the first 24 hours after the burn injury.

D.

will be elevated due to the amount of intravenous fluids administered during the initial phases of treatment.

Answer and Explanation

The Correct Answer is B

A. is expected to be decreased for three to five days.
In the initial stages following severe burn injury, there is often oliguria (low urine output), but this is typically followed by diuresis (increased urine output) after the first 24-48 hours, not a decrease over 3-5 days.

B. will be reduced in the first 24-48 hours and will then increase.
In the first 24-48 hours following a severe burn injury, the body may undergo a state of hypovolemia and oliguria. As fluid resuscitation begins, urine output typically increases.

C. output will be greatest in the first 24 hours after the burn injury.
Although urine output may increase with proper fluid resuscitation, it is not usually greatest in the first 24 hours; the increase typically happens after the initial resuscitation period.

D. will be elevated due to the amount of intravenous fluids administered during the initial phases of treatment.
While fluid resuscitation leads to an increase in urine output after the first 24-48 hours, it is not expected to be elevated right away. The kidneys may initially respond with oliguria.

Correct Answer is D

Explanation

A. Prepare for immediate surgery to repair the open fracture
Surgery may be necessary, but it is not the immediate priority. The focus should be on stabilizing the client and preventing further injury.

B. Assess for pulses in the upper and lower extremities
Assessing circulation is important but is not the most immediate life-saving intervention. First, the client must be stabilized and bleeding controlled.

C. Place a sterile pressure dressing on the open fracture
While controlling bleeding is important, spinal immobilization takes precedence in trauma cases to prevent potential spinal cord injury.

D. Maintain C-spine immobilization
In a trauma patient with loss of consciousness, cervical spine injury must be assumed. Immobilization prevents further damage while other interventions are performed.

Correct Answer is C

Explanation

A. 63% TBSA
This value is too high based on the Rule of Nines calculation.

B. 45% TBSA
This overestimates the burn area.

C. 36% TBSA
Using the Rule of Nines, the TBSA is calculated as follows:

  • Entire right arm (anterior + posterior): 9%
  • Posterior trunk: 18%
  • Posterior right leg: 9%
  • Total TBSA = 9% + 18% + 9% = 36%

D. 27% TBSA
This underestimates the affected areas.
