Which equipment should the nurse use to accurately measure a 2 mL dose of a viscous liquid solution to be administered PO?

A. 3 mL syringe and a sterile needle: While a 3 mL syringe provides accurate measurement, attaching a sterile needle is unnecessary for oral administration. Using a needle for a PO medication could also create a safety risk and is not appropriate practice. B. One ounce (30 mL) medicine cup: Medicine cups are suitable for larger volumes but are not precise for measuring small doses such as 2 mL. Even minor measurement errors with small volumes can significantly affect dosing accuracy, especially for potent or viscous medications. C. 3 mL syringe: A 3 mL syringe provides accurate measurement for a 2 mL dose and is appropriate for oral administration of viscous solutions when used without a needle. The markings on the syringe allow for precise dosing, which is essential for medication safety. D. Tuberculin syringe: A tuberculin syringe is designed for volumes of 1 mL or less and is not the best choice for a 2 mL dose. Using it for this volume could require multiple draws, increasing the risk of dosing errors and contamination.
