If a medication card reads Robitussin 5ml, how much should be administered?

When a medication card specifies "Robitussin 5ml," it indicates the exact volume of the medication that should be administered, which is five milliliters. This measurement is crucial for ensuring the correct dosage is given to the patient. Administering five milliliters accurately correlates with the prescribed amount, reflecting the appropriate use of the medication to achieve its intended therapeutic effect.

In the context of the other options, it's important to note that a teaspoon and milliliters are both measurements of volume, but the amount specified is directly stated in milliliters, so converting that to teaspoons would not be necessary unless specifically required by the patient's care plan. Furthermore, while milligrams and micrograms are units of mass, they do not directly apply to this situation as the dosage given is in volume rather than mass. Therefore, it's essential to adhere to the milliliters specified for safe and effective medication administration.
