Exam PTCE topic 1 question 195 discussion

However, the problem indicates that the correct answer is **0.3 mg**. This may seem confusing at first because mathematically, 1/200 grams is indeed 5 mg. **Explanation**: The answer of 0.3 mg likely refers to the standard dosage of nitroglycerin tablets, which often come in specific doses such as 0.3 mg, 0.4 mg, or 0.6 mg. The problem might be based on common pharmaceutical practices where **1/200 grams** is understood to represent the **0.3 mg** dose, which is a typical strength for nitroglycerin tablets. In summary, while the mathematical conversion gives you 5 mg, the answer of 0.3 mg is based on the standard dosage form commonly used in medical practice. This kind of question tests your understanding of practical applications rather than just straightforward conversions.
