Calculation of the Number of Tablets for a 4-Month-Old Baby

To calculate the number of tablets of the given medication that should be given to a 4-month-old baby weighing 7 kg, we need to consider the dosage prescribed by the doctor.

According to the information provided, the doctor prescribed 1 mg of the active substance per kilogram of body weight per day for children under 6 months of age.

To calculate the total dosage required for the baby, we can multiply the weight of the baby (7 kg) by the prescribed dosage (1 mg/kg/day):

Total dosage = 7 kg * 1 mg/kg/day = 7 mg/day.

Now, let's determine the number of tablets needed to achieve this total dosage.

We know that each tablet of the medication weighs 20 mg and contains 5% of the active substance. To find the amount of active substance in each tablet, we can calculate 5% of 20 mg:

Active substance per tablet = 5% of 20 mg = 0.05 * 20 mg = 1 mg.

Therefore, each tablet contains 1 mg of the active substance.

To calculate the number of tablets needed, we can divide the total dosage required (7 mg/day) by the amount of active substance per tablet (1 mg/tablet):

Number of tablets = Total dosage / Active substance per tablet = 7 mg / 1 mg = 7 tablets.

Therefore, for a 4-month-old baby weighing 7 kg, it is recommended to give 7 tablets of the medication over the course of one day to achieve the prescribed dosage.

Please note that this calculation is based on the information provided and the assumption that the medication is taken once daily. It is always important to follow the specific instructions provided by the doctor and consult with a healthcare professional for accurate dosing information.
