(source: math and dosage calculations for healthcare professionals (booth, 5, isbn 1259166260) > chapter 12: methods of dosage calculations > chapter 13: hermeneutic questions)

Explanation:

Step1: Identify the conversion factor

Since \(1g = 1000mg\), the conversion factor is \(1000mg/1g\)

Step2: Convert the ordered dose to mg

The ordered dose is \(0.5g\). Using the conversion factor: \(0.5g\times1000mg/1g = 500mg\)

Step3: Determine the dosage unit

The dosage unit is \(mg\) (milligrams) as we are dealing with the amount of the drug per tablet in milligrams.

Step4: Identify the dose on hand

The dose on hand is \(500mg\) per tablet (as given by "Flagyl 500mg tablets")

Answer:

Conversion factor: \(1000mg/1g\); Dosage unit: \(mg\); Dose on hand: \(500mg\)
