If a medication card states 0.5 g of Gantrisin, how much should the resident receive?

When interpreting the measurement of medication, it's important to understand the decimal presentation. A medication dosage of 0.5 g indicates that the resident should receive five tenths of a gram. This is mathematically equivalent to half a gram, confirming that the correct dosage is indeed 0.5 g or five tenths gram.

Understanding medical dosages is crucial for ensuring patient safety, as administering the wrong amount could lead to ineffective treatment or potential overdose. The other options present incorrect amounts. Five grams and fifty grams significantly exceed what is required, indicating a serious error in dosage calculation. Similarly, five hundredths gram is much less than what is prescribed, also posing a risk of ineffectiveness in treating the condition for which Gantrisin is being administered.
