To determine the number of tablets the patient should take, we need to know the strength of each tablet.
Assuming each tablet contains 0.025 milligrams (mg) of Synthroid (levothyroxine), we can convert the prescribed dose from decigrams to milligrams:
0.000125 decigrams = 0.00125 milligrams (since 1 decigram = 10 milligrams)
Now, we can divide the prescribed dose by the strength of each tablet:
0.00125 mg ÷ 0.025 mg per tablet = 0.05 tablets
However, we cannot give a patient only a fraction of a tablet. Therefore, we need to round up to the nearest whole tablet:
0.05 tablets rounded up = 1 tablet
Therefore, the patient should take 1 tablet of Synthroid.
