Final answer:
The nurse should ask about the onset of abdominal discomfort, cardiac symptoms before syncopal episode, and duration of warfarin use.
Step-by-step explanation:
Based on the assessment data provided, the nurse should include the following priority questions in the initial assessment:
- Does your abdominal discomfort start? This question helps determine the onset of the symptom and provides important information for evaluating the cause.
- Did you experience cardiac palpitations or chest pain before you passed out? This question helps assess the cardiac status and potential contributing factors to the syncopal episode.
- How long have you been taking warfarin? This question is important to assess the client's anticoagulant therapy and potential interaction with other medications.
