Q. 16.53 - An Introduction to General, Organic, and Biological Chemistry

Question

If Jeremy's current weight is $21\mathrm{lbs}$, how many milligrams of hydroxyurea should Jeremy be given each day?

Step-by-Step Solution

Answer

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

Step1: 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.

Step2: Given Information.

Jeremy's weight$=21 lbs$

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

Step3: Explanation.

Jeremy currently weight $21 lbs.$

Converting lbs into kg:

$$\begin{gathered} 1 \mathrm{lbs}=0.4535\text{ kilograms } \\ 2 1\mathrm{lbs}=9.5235\text{ kilograms } \end{gathered}$$

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

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

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