Question

Ребенку 40 кг назначен препарат. В первый день 25 мг\кг веса,в последующие 12,5 мг\кг один раз в сутки. Форма выпуска таблеток по 0,5г. В упаковке 10 таблеток. Сколько таблеток нужно дать в первый день и последующие? Сколько упаковок нужно на курс 10 дней?

Answer 1

1) 25•40=1000 (мг) = 1 (г) в первый день
2) 12,5•40•9=4500 (мг) = 4,5 (г) со второго по десятый день
3) 1000+4500=5500 (мг) = 5,5г весь курс лечения
Ответ: 2 упаковки нужно на курс

Answer 2

Calculation of Tablet Dosage for a Child

To calculate the number of tablets needed for the first day and subsequent days, we need to follow the given prescription:

- On the first day: 25 mg/kg of body weight - On subsequent days: 12.5 mg/kg of body weight once a day

Given that the child weighs 40 kg and the tablets are available in a 0.5 g (500 mg) formulation, we can proceed with the calculation.

First Day Dosage:

To calculate the dosage for the first day, we need to multiply the child's weight by the prescribed dosage per kilogram:

Dosage for the first day = 25 mg/kg * 40 kg

Let's calculate the dosage for the first day:

Dosage for the first day = 25 mg/kg * 40 kg = 1000 mg

Since each tablet is 500 mg, we need to divide the total dosage for the first day by the tablet strength to determine the number of tablets required:

Number of tablets for the first day = Dosage for the first day / Tablet strength

Number of tablets for the first day = 1000 mg / 500 mg = 2 tablets

Therefore, 2 tablets are needed for the first day.

Subsequent Days Dosage:

For the subsequent days, the dosage is 12.5 mg/kg once a day. Let's calculate the dosage for the subsequent days:

Dosage for subsequent days = 12.5 mg/kg * 40 kg = 500 mg

Again, since each tablet is 500 mg, we need to divide the total dosage for subsequent days by the tablet strength to determine the number of tablets required:

Number of tablets for subsequent days = Dosage for subsequent days / Tablet strength

Number of tablets for subsequent days = 500 mg / 500 mg = 1 tablet

Therefore, 1 tablet is needed for each subsequent day.

Total Number of Tablets for a 10-Day Course

To calculate the total number of tablets needed for a 10-day course, we need to consider the dosage for the first day and subsequent days.

Number of tablets for the first day = 2 tablets Number of tablets for subsequent days = 1 tablet per day

Total number of tablets for a 10-day course = Number of tablets for the first day + (Number of tablets for subsequent days * 9)

Total number of tablets for a 10-day course = 2 tablets + (1 tablet * 9) = 2 tablets + 9 tablets = 11 tablets

Therefore, for a 10-day course, 11 tablets are needed.

Conclusion

To summarize:

- For the first day, 2 tablets are needed. - For each subsequent day, 1 tablet is needed. - For a 10-day course, a total of 11 tablets are needed.
