Parkland Formula Practice Questions for Burns NCLEX (1)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

The answer is A: 22,932 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

The answer is C: 10,064 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

The answer is A: 921 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

The answer is 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

The answer is B: 5,616 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

Parkland Formula Practice Questions for Burns NCLEX (2024)

FAQs

What is the Parkland formula for burns practice? ›

The Parkland formula is Total fluids in first 24 hours=4(Wt in Kg)(%TBSA Burn) with the first half given in the first 8 hours and the other half given in the second 8 hours. Hence, the total fluid to be given in the first 24 hours= 4(20kg)(30)= 2400 ml. 1200 ml should be given in the first 8 hours.

What is the Parkland burn formula for 8 hours? ›

The Parkland formula recommends administration of crystalloid at a rate of 4 mL/kg of percent of total body surface area (TBSA) burned with half of the total fluid volume administered during the first 8 hours from time of injury. This formula initially addressed the serious issue of inadequate resuscitation.

At what hourly rate should the LR be infused over the first 8 hours and the subsequent hourly rate over the following 16 hours? ›

Ringer lactate, 960 mL/h in the first 8 hours, then 480 mL/h for the next 16 hours. Ringer lactate, 640 mL/h for the next 24 hours. Normal saline, 480 mL/h in the first 8 hours, then 960 mL/h for the next 16 hours. Normal saline, 540 mL/h for the next 24 hours.

Which of the following is the correct calculation for the Parkland fluid resuscitation formula? ›

The Parkland formula is as follows: total crystalloid fluid (i.e., a solution with small molecules that can move into cells) over the first 24 hours = 4 milliliters x % TBSA (total body surface area burned) x body weight (kg).

Is Parkland formula 3 or 4 mL? ›

The formula recommends 4 mL per kilogram of body weight in adults and 3 mL per kilogram in children per TBSA of crystalloid solution over the first 24 hours of care.

What is the rule of 9 in burns? ›

The chest equals 9% and the stomach equals 9% of the body's surface area. The upper back equals 9% and the lower back equals 9% of the body's surface area. The front and back of each leg and foot equal 18% of the body's surface area. The genital area equals 1% of the body's surface area.

What is the Parkland formula quizlet? ›

Parkland formula. 4mL/kg/%burn = fluids in 24hrs. divide by 2 = fluids in 1st 8 hours.

How to calculate TBSA for burns? ›

To calculate the %TBSA (quotient), it is necessary to divide the burned surface area (Burned BSA) (numerator in cm2) by the total body surface area (Total BSA) (denominator in cm2).

How fast can you infuse LR? ›

Normal dose of lactated Ringer's

This stands for “keep vein open,” and is usually about 30 milliliters per hour. If you're very dehydrated, a doctor may order fluids infused at a very fast rate, such as 1,000 milliliters (1 liter).

Rate – approximately 2 mL/minute (120mL/hour) for 1st 15 minutes, then increase rate to infuse over 1 to 2 hours (150-250 mL/hr), or as ordered. Do NOT hang longer than 4 hours.

What is the formula for burns on Nclex? ›

4 mL x kg of body weight x TBSA %

To use this formula, you need to know what percentage of the body is burned. If someone has burns on both hands and legs (but not on their torso or head), then you would use 100% for their TBSA.

What is an example of a Parkland formula burn? ›

For example, a person weighing 75 kg with burns to 20% of his or her body surface area would require 4 x 75 x 20 = 6,000 mL of fluid replacement within 24 hours. The first half of this amount is delivered within 8 hours from the burn incident, and the remaining fluid is delivered in the next 16 hours.

What are the guidelines for the Parkland formula? ›

Parkland formula implies 4 mL/kg/%TBSA (3 mL/kg/%TBSA in children) = total amount of crystalloid fluid during the first 24 hours. [29] Discrepancies still exist in patients where the body surface area calculation is unreliable, for example, pediatrics and patients who suffer from obesity.

What is the Parkland method? ›

Parkland technique

Two pieces of dissolvable suture (eg, 0-chromic or plain gut) are passed through this window and used to ligate the proximal and distal ends of a 2- to 3-cm segment of the isthmic fallopian tube. The ligated tube segment is then sharply excised between the sutures.
