How many milligrams will you give each day? Show all work using dimensional analysis
To determine the dosage in milligrams, we need to convert the child's weight from pounds to kilograms.
1 pound is approximately 0.4536 kilograms.
Therefore, the child's weight in kilograms is:
52 lbs * 0.4536 kg/lb = 23.5872 kg
Now, we can calculate the dosage in milligrams.
The dosage is given as 25 mcg/kg, which means 25 micrograms per kilogram of the child's weight.
1 milligram is equal to 1000 micrograms.
So, the dosage in milligrams is:
25 mcg/kg * 23.5872 kg * (1 mg/1000 mcg) = 0.58968 mg
Therefore, the dosage in milligrams will be approximately 0.58968 mg each day.
To calculate the number of milligrams (mg) of Digoxin to give each day, we need to convert the child's weight from pounds (lbs) to kilograms (kg).
1 pound = 0.453592 kg
So, the child's weight in kg is:
52 lbs × 0.453592 kg/lb = 23.587984 kg (rounded to 2 decimal places)
Next, we will calculate the total dose of Digoxin based on the child's weight.
Total dose = Digoxin dose per kg × child's weight
Given that the Digoxin dose per kg is 25 mcg (micrograms), we need to convert it to mg.
1 mg = 1000 mcg
So, the Digoxin dose per kg is:
25 mcg × (1 mg / 1000 mcg) = 0.025 mg/kg
Now we can calculate the total dose of Digoxin:
Total dose = 0.025 mg/kg × 23.587984 kg = 0.5896996 mg (rounded to 2 decimal places)
Therefore, the amount of Digoxin to give each day is approximately 0.59 mg (rounded to 2 decimal places).
