In assessing patients, which condition should be addressed first by the nurse?

Addressing paresthesia secondary to an arterial occlusion takes priority because it indicates a potentially serious condition that can compromise blood flow to a limb. This condition may lead to tissue ischemia and necrosis if not treated promptly. The presence of paresthesia suggests that there may be nerve involvement due to lack of circulation, which can quickly escalate if there is an acute arterial blockage.

In contrast, while severe nausea, chronic pain, and fatigue can all significantly impact a patient's quality of life and require attention, they do not present an immediate threat to the patient's safety or function in the same way that an arterial occlusion does. The urgency of restoring blood flow and preventing irreversible tissue damage is paramount, which is why this condition must be prioritized in the assessment and management of the patient's care.
