The safe dosage of the iv antibiotic ceftriaxone for children weighing more than 2.0 kg is 60. mg per kilogram of body weight. suppose a pediatric nurse has available 1.5 l of a ceftriaxone solution with a concentration of 0.030 g/ml. how can she calculate the volume of this solution that she should administer to a child weighing 41. kg? set the math up. but don't do any of it. just leave your answer as a math expression. also, be sure your answer includes all the correct unit symbols. solution needed = 1 x 5 ?

(41 × 60) / 30 mL of antibiotic solution

Explanation:

The safe dosage of ceftriaxone antibiotic is 60 mg per kilogram of body weight.

Now for a child weighing 41 kg we need:

if we need         60 mg of antibiotic per 1 kg of body weight

then we need   X mg of antibiotic per 41 kg of body weight

X = (41 × 60) / 1 = 41 × 60 mg of antibiotic

The solution of antibiotic have a concentration of 0.030 g/mL and if we transform in milligrams we have a concentration of 30 mg/mL.

Now we our case we need:

if         30 mg of antibiotic are found in 1 mL of solution

then    41 × 60 mg of antibiotic re found in Y mL of solution

Y = (41 × 60 × 1) / 30 = (41 × 60) / 30 mL of antibiotic solution

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
