Which option best defines a dosage?

• A. The color of the pill
• B. Amount and frequency of a medicinal drug that may be taken safely
• C. The patient’s age
• D. The expiration date

Answer: (B)

Dosage is about how much medicine to take and how often to take it, because the safety and effectiveness of a drug depend on both the amount administered and the timing of each dose. The best answer directly describes this: the amount and frequency of a medicinal drug that may be taken safely. This combines the dose (how much) with the interval (how often) to stay within a therapeutic range. Other details here don’t define dosage. Pill color doesn’t indicate how much to take. A patient’s age can influence dosing decisions but isn’t the definition of dosage itself. The expiration date relates to drug quality, not the amount or timing of dosing.
