A patient arrives at the ED complaining of numbness in the left lower leg. Upon assessment, the nurse finds the lower left leg to be cold to touch, pedal and posterior tibial pulses nonpalpable, and a sharp line of paralysis/paresthesia. The nurse's next action is based on the fact that
A) acute arterial occlusion is a medical emergency requiring immediate intervention to restore blood flow.
B) submersion in a whirlpool with warm water will improve the venous blood flow and restore pulses.
C) the immediate infusion of tissue plasminogen activator (tPA) will not correct the problem and should only be used for CVAs.
D) administration of an aspirin and sublingual nitroglycerin will vasodilate the artery to restore perfusion.

The presentation of acute arterial embolism is often described as that of the seven "P's": pistol shot, pallor, polar, pulselessness, pain, paresthesia, and paralysis. Treatment is aimed at restoring blood flow. Embolectomy, thrombolytic therapy, and anticoagulant therapy (heparin) are usually given. Application of cold should be avoided.
