病人預計接受需使用游離輻射之處置，護理師應優先執行哪些措施？（選所有適合的）
A client is scheduled for a procedure requiring the use of ionizing radiation. Which interventions should the nurse prioritize? (Select all that apply.)
- AVerify the client's pregnancy status✓ 正解確認病人的懷孕狀況
- BMinimize time spent near the radiation source✓ 正解減少在輻射源附近的停留時間
- CIncrease distance from the radiation source✓ 正解增加與輻射源的距離
- DPlace a lead apron on the client for full-body protection為病人穿上全身防護鉛衣
- EUse radiation shielding devices between the source and staff✓ 正解在輻射源與工作人員之間放置輻射遮蔽裝置

輻射安全原則為 ALARA（As Low As Reasonably Achievable）。需確認有無懷孕以避開胎兒風險，採取時間（Time）、距離（Distance）、屏蔽（Shielding）三大原則。全身體鉛衣（D）通常不切實際，應依部位遮蔽。
The nurse should prioritize radiation safety principles, specifically ALARA (As Low As Reasonably Achievable), by verifying pregnancy status to protect the fetus and minimizing exposure through time, distance, and shielding. Interventions include reducing time near the source, increasing distance based on the inverse square law, and using protective barriers for staff, while recognizing that full-body lead aprons are impractical.
