Answer :
Using the American Burn Association's Parkland formula for fluid resuscitation for a client with 42% TBSA burn who weighs 165 lb, the nurse should set the pump to administer approximately 785 mL per hour for the first 8 hours.
To calculate the fluid resuscitation for a 165 lb. client with a 42% TBSA (Total Body Surface Area) thermal burn using the American Burn Association formula, we first need to convert the client's weight from pounds to kilograms. Knowing that 1 pound is approximately 0.453592 kilograms, the client's weight in kilograms is 165 lb × 0.453592 kg/lb, which equals roughly 74.8 kg (rounded for simplicity).
The American Burn Association recommends the Parkland formula for burn fluid resuscitation, which is 4 mL/kg/TBSA%. For the first 24 hours after the burn, the total fluid requirement is calculated and half of this total volume is given in the first 8 hours starting from the time of the burn. For our 165 lb client with a 42% TBSA burn, the calculation would be:
4 mL/kg × 74.8 kg × 42% = 12566.4 mL
Since half of this fluid is given in the first 8 hours, the amount to be administered during the first 8 hours is:
12555.4 mL / 2 = 6283.2 mL
Thus, to determine the rate at which the pump should be set to administer per hour, we divide this amount by 8 hours:
6283.2 mL / 8 hours = 785.4 mL/hour
The nurse should set the pump to deliver approximately 785 mL per hour for the first 8 hours to meet the resuscitation criteria. It is essential to round to a practical rate for the infusion pump, therefore 785 mL/hour would be appropriate.
6285.468 ml/hr is to be administered to the victim of weight 165lb and tbsa is of 42% by the nurse.
It is given that the weight of the body is 165lb (ie) 74.827kg and the total body surface are (tbsa) thermal burn is 42%. To set the pump to administer, the following formula is used:
Initial fluid resuscitation of burn victims = 4 mL of Ringer's lactate x kilogram of body weight x %TBSA burned
This formula is known as Parkland Formula or or American burn association formula fluid resuscitation. Using this formula, the amount of fluid to be administered could be calculated for 24 hours.
On substituting the values we get,
Initial fluid resuscitation of the burn victim = 4 x 74.827 x 42
Initial fluid resuscitation of the burn victim = 12570.936ml
This is to be administered for 24 hours. For administering for 8 hours, half of this value is to be used, that is
Initial fluid resuscitation of burn victim for first 8hours = 12570.936/2
Initial fluid resuscitation of burn victim for first 8 hours = 6285.468 ml/hr
Therefore, for first 8 hours, 6285.468 ml is to be administered to the victim.
