gr stands for which term?

• A. Gram
• B. Gravitational
• C. Grain
• D. Gross

Answer: (C)

The main idea is recognizing historical weight abbreviations. Gr stands for grain, a small unit of mass used in the apothecary system. One grain equals about 64.8 milligrams, so a label reading 1 gr would be roughly 64.8 mg of the drug. This differs from gram, which is abbreviated g in the metric system, and from gravitational (g) or gross, which are not used as mass units in this context. Modern dosing typically uses milligrams, but knowing that gr means grain helps you interpret older prescriptions or labels.
