85. Which of the following abbreviations means one-half?
Answer: D
ss means one-half
The abbreviation "ss" is commonly used in medical and scientific contexts to denote "one-half." This notation is often employed in prescriptions and dosage instructions.
A) sq
The abbreviation "sq" typically stands for "square," as in square units of measurement or area, and is not related to the concept of one-half. Therefore, this option is incorrect.
B) qs
"qs" is an abbreviation that stands for "quantum satis," meaning "a sufficient quantity." It does not imply one-half and is used to indicate that a sufficient amount should be added, making this option incorrect.
C) sl
The abbreviation "sl" is generally associated with "sublingual," referring to a method of drug administration under the tongue. It does not relate to the meaning of one-half, thus this option is also incorrect.
D) ss
The abbreviation "ss" specifically denotes "one-half" in medical terminology and is often used in prescribing medication dosages. This makes it the correct answer to the question.
Conclusion
The abbreviation "ss" is definitively the correct representation of one-half, while the other options—"sq," "qs," and "sl"—have distinct meanings unrelated to this concept. Understanding these abbreviations is crucial in contexts where precise dosages or measurements are necessary.
