Using the Parkland formula, calculate the fluid rate per hour for a patient with 30% TBSA burn, weighing 75 kg, during the first 8 hours of fluid resuscitation.
450 mL/hr
700 mL/hr
675 mL/hr
562.5 mL/hr
The Correct Answer is D
Parkland formula:
4 mL × weight (kg) × %TBSA = total fluid in 24 hours
= 4 × 75 × 30 = 9,000 mL total
Half of this is given in the first 8 hours:
9,000 ÷ 2 = 4,500 mL
Fluid rate per hour for first 8 hours:
4,500 mL ÷ 8 hours = 562.5 mL/hr
Therefore, the correct Answer is D.

Correct Answer is D
Explanation
A. Blackened dead skin (eschar) is indicative of a full-thickness (third-degree) burn, not a first-degree burn.
B. Blistering suggests a partial-thickness (second-degree) burn, often caused by more intense heat or flame exposure.
C. Excessive scarring typically results from deeper burns, such as second- or third-degree burns, not superficial ones.
D. A sunburn is a classic example of a first-degree burn, which affects only the epidermis and presents with redness, pain, and mild swelling but no blisters or scarring.
Correct Answer is C
Explanation
A. The body is not divided into nine equal areas; the name refers to approximate multiples of nine for each section.
B. The rule helps estimate the percentage of body surface area (BSA) burned, not calculate total BSA.
C. The rule of nines is a quick method to estimate the percentage of total body surface area affected by burns in adults. Each major section of the body is assigned a value that is a multiple of nine, aiding in fluid resuscitation and treatment planning.
D. It is primarily used for adults; modified charts, such as the Lund and Browder chart, are more accurate for children due to their different body proportions.
