An older patient with chronic atrial fibrillation develops sudden severe pain, pulselessness, pallor, and coolness in the right leg, consistent with acute arterial occlusion.

After the nurse notifies the healthcare provider, what should the nurse do next?

Choice A rationale
Venous thrombosis is a condition in which a blood clot forms in a vein, typically in the leg. While this condition can cause discomfort and changes in the appearance of the leg, it would not typically cause the leg to become cold and pale or result in the loss of a pulse.
Choice B rationale
Paresthesia refers to abnormal sensations in the body, such as tingling, numbness, or burning. While this condition could potentially cause discomfort, it would not typically cause the leg to become cold and pale or result in the loss of a pulse.
Choice C rationale
Vascular spasm is a sudden, brief tightening of the muscles inside the walls of a blood vessel. While this could potentially cause discomfort and changes in the appearance of the leg, it would not typically cause the leg to become cold and pale or result in the loss of a pulse.
Choice D rationale
Arterial occlusion is the correct answer. This condition involves a blockage in an artery, which can significantly reduce blood flow to the affected area. This could cause the leg to become cold and pale and result in the loss of a pulse.

Choice A rationale
Ulceration on the medial surface of the lower legs is not the best description of stasis dermatitis in a patient with peripheral vascular disease (PVD). While ulcers can occur in severe cases, they are not the primary characteristic of stasis dermatitis.
Choice B rationale
Stasis dermatitis, also known as venous stasis dermatitis, is a skin inflammation that occurs in people with poor circulation. It most often happens in the lower legs because that’s where blood typically collects. When blood pools in the veins of the lower leg, it can cause a variety of symptoms, including a brownish skin discoloration on the lower legs. This discoloration is caused by the leakage of red blood cells into the skin due to increased pressure in the veins.
Choice C rationale
While edema in the lower legs can be a symptom of PVD and may accompany stasis dermatitis, it is not the best description of the condition. Edema is a general symptom that can occur in many conditions and is not specific to stasis dermatitis.
Choice D rationale
A purple rash on the medial surface of the lower legs is not a typical symptom of stasis dermatitis. While the skin may become discolored, it is usually a brownish color rather than purple.
