A nurse assesses patients in an osteoporosis clinic. Which patient would the nurse assess first?

Choice A reason: Occasional dyspepsia is a common side effect of bisphosphonates like Risedronate and is not immediately life-threatening. It warrants monitoring but is not urgent. Choice B reason: Forgetting the last dose of Ibandronate may affect treatment efficacy but does not pose an immediate risk. The nurse can clarify dosing and reinforce education. Choice C reason: Flank pain could suggest renal calculi, especially with calcium supplementation, but if it occurred two weeks ago and has resolved, it is not the most urgent concern. Choice D reason: Unilateral calf swelling raises concern for deep vein thrombosis (DVT), a potentially life-threatening condition. Raloxifene increases the risk of thromboembolic events, making this patient a priority for assessment.
