What finding is indicative of arterial insufficiency when a client experiences foot pain?

The presence of cool extremities is indicative of arterial insufficiency when a client experiences foot pain. This symptom arises because inadequate blood flow, due to narrowed or blocked arteries, leads to reduced temperature in the affected limb. When arterial insufficiency occurs, the body struggles to deliver sufficient oxygen-rich blood to the tissues, which can result in a range of symptoms, including coolness in the feet or legs.

In contrast, decreased heart rate might relate to other cardiovascular conditions but does not specifically indicate insufficient arterial blood flow. Increased blood pressure could occur in various scenarios, including stress or pain, and does not point towards arterial insufficiency. Hot, swollen feet would generally suggest venous insufficiency or inflammation rather than arterial problems. Thus, the observation of cool extremities serves as a clear signal of impaired circulation, supporting the diagnosis of arterial insufficiency.
