The Parkland formula is
V = 4mA
where
V = volume of replacement fluid (mL) required within the first 24 hours after a burn injury,
m = body mass, kg
A = percent of body surface area covered with burns.
The first half of the fluid should be delivered in the first 8 hours.
Because we are concerned with fluid replacement within the first 8 hours, the Parkland formula is valid to be used.
Given:
m = 75 kg
A = 40%
Therefore
V = 4*75*40 = 12,000 mL = 12 L
This is the fluid replacement required in the first 24 hours.
Because half of this amount should be delivered in the first 8 hours, the amount of fluid replacement is
6,000 mL in 8 hours, or
6000/8 = 750 mL per hour.
Answer: 750 mL every hour
Answer:
cos(∅) = 3/5
Step-by-step explanation:
cos(∅) = adjacent/hypotenuse
We don't know what the hypotenuse is so we gotta use Pythagorean theorem to find it.
a² + b² = c²
4² + 3² = c²
√(4² + 3²) = c
c = 5 , this is our hypotenus
cos(∅) = adjacent/hypotenuse
cos(∅) = 3/5
6 friends share 5 meat pies...
each friend eats half a pie.....6 * 1/2 = 6/2 = 3 pies eaten
so now there r 2 pies left
2/6 = 1/3.....so each friend has to eat 1/3 of a pie
