To determine how much cold medication is needed for a person weighing 225 lb, you can use a simple proportion. Since the dosage is 2 mg for every 60 lb, you set up the equation as follows: (2 mg / 60 lb) = (x mg / 225 lb). By cross-multiplying and solving for x, you’ll find that x equals 7.5 mg. It’s always a great idea to double-check calculations when dealing with medication dosages!

When measuring medication based on body weight, it’s essential to avoid common mistakes such as misreading the weight or dosage unit. Ensure that you convert weight correctly if necessary, and always round off to the nearest whole number when appropriate, especially in a clinical setting. This way, you minimize the risk of under- or overdosing and enhance patient safety!
