Final answer:
The nurse will administer 2 tablets of Amoxicillin to achieve the prescribed dose of 0.25g, as each tablet contains 125mg.
Step-by-step explanation:
The prescription dosage for Amoxicillin is 0.25g to be taken orally every 8 hours. The pharmacy has Amoxicillin in 125mg tablets. To determine how many tablets the nurse will administer, we need to convert grams to milligrams. Since 1 gram is equal to 1000 milligrams, 0.25 grams is the same as 250 milligrams. Since each tablet contains 125 milligrams, the nurse needs to administer 2 tablets to meet the 0.25g (or 250mg) prescription dose.
The conversion process involves the following steps:
- Converting grams to milligrams: 0.25g × 1000 = 250mg
- Dividing the prescribed milligrams by the milligram amount per tablet: 250mg ÷ 125mg/tablet = 2 tablets
This calculation ensures that the patient receives the correct dose of medication, following the principles of dosage and route of administration to achieve therapeutic drug levels and minimize risk of side effects.
