Final answer:
The Rule of Nines is used to estimate the percentage of a patient's total body surface area burned. The Parkland Formula is used to calculate the fluid volume needed for resuscitation in the first 24 hours after a burn injury.
Step-by-step explanation:
The Rule of Nines is a method used to estimate the percentage of a patient's total body surface area (TBSA) that has been burned. According to the Rule of Nines, each major body part represents a specific percentage of TBSA. For an adult patient, the anterior trunk represents 18% of TBSA, the lower back represents 18% of TBSA, and the anterior right arm represents 9% of TBSA. To calculate the patient's TBSAB (Total Body Surface Area Burned), you simply add up the percentages: 18% + 18% + 9% = 45%.
The Parkland Formula is used to calculate the fluid volume needed for resuscitation in the first 24 hours after a burn injury. According to the Parkland Formula, the total fluid volume needed is 4 mL × TBSAB × body weight in kg. In this case, the patient's TBSAB is 45% and their body weight is 80 kg. So the fluid volume needed in the first 8 hours after arrival would be: 4 mL × 45% × 80 kg = 1440 mL.
