Which dosage instruction corresponds to 1 spray?

The correct choice for the dosage instruction corresponding to 1 spray is indicated as SP1. This notation is designed to be clear and concise, where "SP" stands for "spray," and the "1" indicates the quantity. Therefore, SP1 specifically communicates that a single spray is to be administered.

In the context of medication administration, precision is crucial, and the use of standardized abbreviations helps ensure that healthcare providers can quickly and accurately interpret dosage instructions. For this reason, SP1 is the appropriate choice, as it straightforwardly reflects the instruction for a single spray.

Using alternatives, such as SP2 or I2P, could lead to confusion since they suggest different quantities or methods of administration. Furthermore, 2P does not adhere to the standardized notation for sprays and could lead to misinterpretation or dosing errors. Each of these options lacks the clarity needed to convey the exact dosage effectively.
