Premarin 1.25 mg is ordered daily for your patient. The only available tablet strength is 625 mcg. What amount will you give?

a) 1 tablet
b) 3 tablets
c) 5 tablets
d) 2 tablets

Answer 1

To determine the number of tablets needed, convert the dosage and tablet strength to the same unit. Divide the dosage by the tablet strength to find the number of tablets needed. You will give the patient 2 tablets.

Step-by-step explanation:

To determine the number of tablets needed, we need to convert the dosage and tablet strength to the same unit. The dosage of Premarin is given as 1.25 mg and the tablet strength is given as 625 mcg. Since 1 mg is equal to 1000 mcg, we can convert the dosage to mcg by multiplying 1.25 mg by 1000, which equals 1250 mcg. Now we can divide the dosage by the tablet strength to find the number of tablets needed:

Number of tablets = 1250 mcg / 625 mcg

Number of tablets = 2 tablets

Therefore, you will give the patient 2 tablets.
