Final answer:
The correct abbreviation for a prescription is RX, which includes medication, dosage, and instructions for a patient. The options 'o' or RX should be used for prescriptions, not 'sx', which typically stands for symptoms.
Step-by-step explanation:
The abbreviation for a prescription, which includes the medication, dosage, and instructions for a patient, is RX. In medical terminology, the symbols and abbreviations are numerous, but for prescriptions, RX is universally recognized. Furthermore, when trying to distinguish which abbreviation to use, it's important to consider the most commonly accepted one in the medical community.
In the context provided, where both 'o' and 'sx' are given in what seems like a questionnaire or test, the correct abbreviation for a prescription is 'o' or RX. The use of 'sx' is incorrect as 'SX' generally stands for symptoms. Always use the abbreviation that accurately represents the information needed, which in this case is RX for prescription details.
