Final answer:
The total amount of Lactated Ringers administered to a burn patient over 24 hours is calculated using the Parkland Burn Formula, which requires 4 mL x patient's weight in kg x %BSA of the burns.
Step-by-step explanation:
To calculate the total amount of Lactated Ringers that will be administered over the next 24 hours for a 45 year old female patient using the Parkland Burn Formula, the extent of the burns in terms of body surface area (BSA) must first be determined. Then, the Parkland Formula, which is 4 mL x patient's weight in kg x %BSA, is applied.
Once these details are available, the calculation can be performed, and the fluid requirement for the first 24 hours post-burn will be obtained.
