Final answer:
The question to assess the "R" in OPQRST when assessing a patient with chest pain is whether the pain radiates to other areas.
Step-by-step explanation:
When assessing a patient who complains of chest pain, one of the questions you would ask to assess the "R" in OPQRST is: 3) Does the pain radiate to other areas? This question helps determine if the pain is localized or if it spreads to different parts of the body. In the case of an acute myocardial infarction (MI), the pain may radiate down the left arm in males. Knowing this information can assist in identifying the cause of the chest pain.
