Step-by-step solution

Introduction.

Sickle cell anemia is a genetic disorder in which a mutation in the DNA changes the amino acid in the protein, affecting the protein structure. As a result, hemoglobin's structure changes from round to sickle cell, destroying its ability to transport oxygen.

Given Information.

Jeremy's weight$=21lbs$

Determine how many milligrams of hydroxyurea Jeremy should be given each day.

Explanation.

Jeremy currently weight$21lbs.$

Converting lbs into kg:

$$\begin{gathered} 1\mathrm{lbs}=0.4535\text{kilograms} \\ 21\mathrm{lbs}=9.5235\text{kilograms} \end{gathered}$$

A daily dose $20mg$of hydroxyurea per kg body weight was recommended.

$$\begin{gathered} =9.5235\times 20/1 \\ =190.47mg \end{gathered}$$

Every day, Jeremy should be given $190.47$milligrams of hydroxyurea.
