Real-Life Math -- Solution
You want to calculate how much fluid Camille needs per hour.
Amount
of dehydration = 10 kg x 0.15
Amount of dehydration = 1.5 kg
1.5
kg = 1.5 L (1,500 ml)
Total amount needed = 1,500 ml + 800
ml normal amount
Total amount needed = 2,300 ml
Amount
needed per hour = 2,300 ml / 24 hours
Amount needed per hour
= 95.83 ml
Camille needs about 96 ml per hour to be rehydrated.
Gastroenterologists
use basic mathematics quite often. They especially need to understand statistics.
"You
have to have an understanding of statistics in medicine to understand the
research journals, so that you can then treat people appropriately, according
to the latest information available," says Dr. Geoff Withers. He's a
pediatric physician subspecializing in gastroenterology.
Physics
and chemistry courses are required courses for anyone getting into medicine.
"It's
not necessarily a math-intensive area," Withers says. "Math skills would be
helpful, but I don't consider my math skills very good, and I've
managed to get here without that much difficulty."
