Question

Supply: Erythromycin 250 mg per tablet
Order: Erythromycin 0.5 Gm orally every 8 hours

Answer 1

To meet the prescribed dose of 0.5 Gm of Erythromycin every 8 hours, the patient needs to take 2 tablets of Erythromycin 250 mg per tablet.

Step-by-step explanation:

The student is asking how many tablets of Erythromycin should be given to fulfill a prescription. The prescription requires 0.5 grams (Gm) of Erythromycin to be taken orally every 8 hours, and each tablet available contains 250 milligrams (mg) of Erythromycin. Since 1 gram equals 1000 milligrams, 0.5 grams is equal to 500 milligrams.

To calculate the number of tablets required per dose, we use the following steps:

Determine the total milligrams needed per dose: 500 mg (since 0.5 Gm = 500 mg).

Divide the total milligrams needed per dose by the milligrams per tablet: 500 mg ÷ 250 mg/tablet.

The result is 2 tablets per dose.

Therefore, the patient needs to take 2 tablets of Erythromycin 250 mg every 8 hours to meet the prescribed dose of 0.5 Gm.

Answer 2

To administer a 0.5 Gm dose of Erythromycin, the patient should take two 250 mg tablets every 8 hours, as each gram contains 1,000 milligrams.

Step-by-step explanation:

The student's question relates to the calculation of the correct dosage of Erythromycin to be administered orally, based on the prescribed amount and the supply on hand. Erythromycin, a macrolide antibiotic, is effective against a variety of bacterial infections and works by inhibiting protein synthesis in the microorganism.

To convert the prescribed dosage of 0.5 Gm (grams) into milligrams (mg), we multiply by 1,000 (since there are 1,000 milligrams in a gram), which gives us 500 mg. Given that each tablet contains 250 mg, the patient would need to take two tablets to meet the prescribed dose of 0.5 Gm every 8 hours.
