Which pair correctly maps the abbreviations to their meanings?

• A. DX: Diagnosis, RX: Radiation
• B. DX: Diagnosis, RX: Recovery
• C. DX: Diagnosis, RX: Prescription
• D. DX: Diagnosis, RX: Registration

Answer: (C)

In medical shorthand, DX is used for diagnosis—the identification of a patient’s condition. RX is used to indicate a prescription—the instructions for what the patient should obtain and take, such as glasses or medications. Radiation, in medical contexts, isn’t typically abbreviated as RX; radiation therapy is usually shown as RT or XRT. So the pairing where DX means diagnosis and RX means prescription is the correct one. The other options mix RX with terms like recovery or registration, which aren’t standard meanings in clinical shorthand.
