Capsules must be rounded to the nearest what?

Capsules must be rounded to the nearest whole number. This is because capsules are typically sold in whole units and cannot be divided. When calculating dosages that involve capsules, it is essential to ensure that the final amount prescribed or administered is a complete capsule, as partial capsules cannot be accurately dispensed or consumed. Rounding to the nearest whole number ensures that patients receive an appropriate and effective dose in a safe manner.

In the context of the other options, rounding to the nearest tenth, half, or quarter is not applicable because these increments would result in impractical or impossible dosing of capsules. Ensuring the dosage is a whole number maintains the integrity of the medication dispensing process.
