How many milligrams are in 1 tbsp dose of a liquid medication if there are 2 grams in 4 fl oz?
The correct answer and explanation is:
Correct Answer: 250 milligrams
Explanation:
To solve this problem, begin by converting all the units so they can be compared easily. The question is asking for how many milligrams (mg) are in 1 tablespoon (tbsp) of a liquid medication, knowing that 2 grams (g) of medication are present in 4 fluid ounces (fl oz).
Step 1: Convert grams to milligrams.
1 gram (g) = 1,000 milligrams (mg)
So, 2 grams = 2 × 1,000 = 2,000 mg
Step 2: Understand the volume relationship.
1 fl oz = 2 tablespoons (tbsp)
So, 4 fl oz = 4 × 2 = 8 tbsp
Now, we know:
2,000 mg are in 8 tbsp of the liquid
Step 3: Find how many milligrams are in 1 tbsp.
2,000 mg ÷ 8 tbsp = 250 mg per tbsp
So, a 1 tablespoon dose contains 250 milligrams of the medication.
This type of conversion problem is common in pharmacy and healthcare settings. It tests your ability to handle unit conversions involving both mass and volume. Accurate dosage conversions are critical for patient safety. An incorrect conversion might result in underdosing or overdosing. By breaking down the problem step-by-step, and using known conversion factors, the process becomes reliable and repeatable. Mastery of these skills ensures confidence in real-life medical dosage scenarios.
