If a prescription calls for 1.5 grams of medication, how many milligrams should be administered?

150 mg 500 mg 1000 mg 1500 mg

Correct Answer:

1500 mg

Explanation:

To determine how many milligrams correspond to 1.5 grams, it is essential to understand the relationship between these two units of measurement. There are 1000 milligrams in 1 gram. Therefore, when you want to convert grams to milligrams, you multiply the number of grams by 1000. In this case, 1.5 grams can be calculated as follows: 1.5 grams × 1000 mg/gram = 1500 mg. Thus, when a prescription specifies 1.5 grams of medication, it translates to 1500 milligrams that need to be administered. This conversion is fundamental in the healthcare field, as using the correct measurement is crucial for patient safety and effective medication administration.
