Final answer:
Medications in syringes are measured by aligning the calibrations with the bottom ring of the rubber tip of the plunger, which is a standard practice for accurate dosage.
Step-by-step explanation:
Medications are measured in syringes by aligning the calibrations with the bottom ring of the rubber tip of the plunger. This practice ensures accuracy in medication dosage. When using the syringe, it is essential to ensure that the measuring scale is properly aligned with the reference point, which in this case is the bottom ring of the plunger's rubber tip. This method is similar to the way liquid volumes are measured in a graduated cylinder, where the reading is taken at the bottom of the meniscus to ensure precise measurements.
