A nurse in an outpatient clinic is collecting data from a client who reports pain in the legs when walking, but the pain stops when stopping walking. Which of the following conditions should the nurse suspect?

Choice A reason: Calcium deficiency causes muscle cramps or tetany, not pain relieved by rest. Intermittent claudication, pain during walking that resolves with rest, is characteristic of peripheral arterial disease, not hypocalcemia. This condition does not affect vascular flow, making it an incorrect suspicion for this symptom. Choice B reason: Peripheral vascular problems, specifically peripheral arterial disease, cause intermittent claudication, characterized by leg pain during walking due to reduced arterial blood flow. Pain resolves with rest as oxygen demand decreases. This matches the client’s symptoms, making it the most likely condition the nurse should suspect. Choice C reason: Acute vessel obstruction causes sudden, severe pain not relieved by rest, often with pallor or pulselessness, unlike intermittent claudication. The client’s pain relief with rest suggests chronic arterial insufficiency, making acute obstruction less likely than peripheral vascular disease as the suspected condition. Choice D reason: Diabetes mellitus contributes to peripheral vascular disease but is not the direct cause of claudication-like pain. Pain relieved by rest points to arterial insufficiency, not solely diabetes. Peripheral vascular problems better explain the symptoms, as diabetes is a risk factor, not the primary condition.
