The abbreviation sig means \( \begin{array}{ll}\text { a. amount } \\ \text { b. prescription } \\ \text { c. at bedtime } \\ \text { d. to be labeled accordingly }\end{array} \)

The abbreviation "sig" comes from the Latin word "signa," meaning "to be labeled." It's commonly used on prescriptions to indicate how the medication should be taken by the patient. This way, pharmacists can ensure that patients know exactly what their doctor intends regarding dosage and directions. In real-world application, understanding abbreviations like "sig" is crucial for both healthcare professionals and patients. For example, if a doctor writes "sig: take 1 tablet by mouth twice daily," it helps avoid any confusion about how to properly take the medication. Knowing these abbreviations promotes safe and effective medication use!
