Question

In absence of instruction by the prescriber, unless otherwise directed, the dose given for the mixture preparation should be stated on the label as

• A. Two five ml spoonful to be taken three times a day in water
• B. One five ml spoonful to be taken three times a day in water
• C. Two five ml spoonful to be taken two times a day in water
• D. One five ml spoonful to be taken two times a day in water

Answer 1

The Correct Option is A

In the context of dispensing and hospital pharmacy, the proper labeling of medicine doses is crucial for patient safety and effective treatment. In this scenario, we need to determine the standard dosing instructions for a mixture preparation in the absence of specific instructions from a prescriber.

The options provided are:

• Two five ml spoonful to be taken three times a day in water
• One five ml spoonful to be taken three times a day in water
• Two five ml spoonful to be taken two times a day in water
• One five ml spoonful to be taken two times a day in water

According to standard medical practice, unless otherwise instructed by the prescriber, the general guideline is to administer a typical adult dose. Given the options, "Two five ml spoonful to be taken three times a day in water" is consistent with common practice for mixture preparations.

Reasons for selecting this option:

1. Standard Dosage Volume: Using 10 ml per dose (two 5 ml spoonfuls) is a typical volume for liquid medications intended for adults, providing an adequate concentration of therapeutic agents.
2. Frequency: Administering the dose three times a day ensures more consistent levels of the medication in the bloodstream, leading to better therapeutic effectiveness.
3. Solubility and Administration: Instructions to take the dose with water help facilitate proper ingestion and absorption of the medication.

By ruling out the other options:

• "One five ml spoonful" could be insufficient for effective treatment depending on the medication's potency and indications.
• "Two five ml spoonfuls two times a day" provides less frequent dosing, which might not maintain an effective blood concentration level of the medication.

Thus, the correct answer is, "Two five ml spoonful to be taken three times a day in water."
