Given that the <span>standard guidelines for fluid intake recommend that a 10 - 20 kg child should have 1000 mL of fluid plus 50 mL for each full kilogram of body weight over 10 kg per day.
1 ounce contains 29.57 mL of fluid, thus an 8-ounce glass contains 8(29.57) = 236.56 mL of fluid.
1 pound is equivalent to </span>0.45 kg, thus, 43 pound is equivalent to 43(0.45) = 19.35 kg
Thus, the <span>standard guidelines for fluid intake recommend for a 43 pounds (19.35 kg) child is given by 1000 + 9(50) = 1000 + 450 = 1450 mL of fluid per day.
