Which unit indicates a larger measurement than '100 units' in medication dosages?

The unit that indicates a larger measurement than '100 units' is 1000 units. This is because '1000 units' is directly a higher numerical value compared to '100 units'. Understanding the concept of unit measurement is crucial in pharmacy, as accurate dosages are essential for effective patient care and medication management. In medicinal contexts, larger units generally correspond to increased dosages, which may be necessary for certain medications or for patients with specific needs. The other choices represent values that are smaller than '100 units', confirming that they do not meet the criteria for indicating a larger measurement.
