Parkland Formula Practice Questions Answer Key

Parkland Formula Practice Questions Answer Key 1. A 45 year old female patient has superficial partial thickness burns on the posterior head and neck, front of the left arm, front and back of the right arm, posterior trunk, front and back of the left leg, and back of right leg. The patient weighs 91 kg. Use the Parkland Burn Formula to calculate the total amount of Lactated Ringerss that will be given over the next 24 hours? A. 22,932 mL B. 26,208 mL C. 16,380 mL D. 12,238 mL Formula: Total Amount of LR = 4 mL x BSA % x pt’s weight in kg Pt’s weight 91 kg. BSA percentage: 63%… posterior head and neck (4.5%), front of the left arm (4.5%), front and back of the right arm (9%), posterior trunk (18%), front and back of the left leg (18%), back of right leg (9%) equals: 63% 4 x 63 x 91 = 22,932 mL 2. A 30 year old female patient has deep partial thickness burns on the back of the right arm, posterior trunk, front of the left leg, anterior head and neck, and perineum. The patient weighs 150 lbs. Use the Parkland Burn Formula to calculate the total amount of Lactated Ringers that will be given over the next 24 hours? A. 14,960 mL B. 12,512 mL C. 10,064 mL D. 16,896 mL Formula: Total Amount of LR = 4 mL x BSA % x pt’s weight in kg Pt’s weight 150 lbs….convert to kg….150 divided by 2.2 = 68 kg BSA percentage: 37%…Back of right arm (4.5%), posterior trunk (18%), front of left leg (9%), anterior head and neck (4.5%) and perineum (1%) which equals 37%. 4 x 37 x 68 = 10,064 mL 3. A 30 year old female patient has deep partial thickness burns on the front and back of the right and left leg, front of right arm, and anterior trunk. The patient weighs 63 kg. Use the Parkland Burn Formula: What is the flow rate during the FIRST 8 hours (mL/hr) based on the total you calculated? A. 921 mL/hr B. 938 mL/hr C. 158 mL/hr D. 789 mL/hr First calculate the total amount of fluid needed with the formula: Total Amount of LR = 4 mL x BSA % x pt’s weight in kg. The pt’s weight 63 kg. BSA percentage: 58.5%…Front and back of right and left leg (36%), front of right arm (4.5%), anterior trunk (18%) which equals 58.5%. 4 x 58.5 x 63 = 14,742 mL Remember during the FIRST 8 hours 1/2 of the solution is infused, which will be 14,742 divided by 2 = 7371 mL. Hourly Rate: 7371 divide by 8 equals 921 mL/hr 4. A 59 year old male patient has full thickness burns on both of the legs on the back, front and back of the trunk, both arms on the front and back, and front and back of the head and neck. The patient weighs 186 lbs. Use the Parkland Burn Formula: You’ve already infused fluids during the first 8 hours. Now what will you set the flow rate during the next 16 hours (mL/hr) based on the total you calculated? A. 563 mL/hr B. 854 mL/hr C. 289 mL/hr D. 861 mL/hr First calculate the total amount of fluid needed with the formula: Total Amount of LR = 4 mL x BSA % x pt’s weight in kg. The pt’s weight 186 lbs…need to convert to kg: 186 divided by 2.2 = 85 kg BSA percentage: 81%…Both of the legs on the back (18%), front and back of the trunk (36%), both arms on the front and back (18%), front and back of the head and neck (9%) which equals 81%. 4 x 81 x 85 = 27,540 mL You’ve already infused half of the solution during the first 8 hours…so 13,770 mL is left and it needs to be infused over 16 hours. Hourly rate: 13,770 mL divided by 16 hours equals 861 mL/hr 5. A 29 year old male patient has superficial partial thickness burns on the anterior right arm, posterior left leg, and anterior head and neck. The patient weighs 78 kg. Use the Parkland Burn Formula to calculate the total amount of Lactated Ringers that will be given over the next 24 hours? A. 11,232 mL B. 5,616 mL C. 2,808 mL D. 16,848 mL Formula: Total Amount of LR = 4 mL x BSA % x pt’s weight in kg Pt’s weight 78 kg BSA percentage: 18%…Anterior right arm (4.5%), posterior left leg (9%), and anterior head and neck (4.5%) which equals 18%. 4 x 18 x 78 = 5,616 mL
