A49-year old woman presents to a rural emergency department with acute onset monocular vision loss in her right eye. she denies pain or any other deficits but states she has been feeling nervous and has lost weight over the past three weeks. on physical exam, she has complete visual field loss in the right eye. fundoscopic exam reveals a pale retina and a single bright red spot just off of center. after she is treated appropriately for her emergent problem, what additional testing is most appropriate?

ECG

Explanation:

An ECG is appropriate to determine if her heart is working properly. Problems with her heart or her arterial pressure could have caused the loss of her visual field and that red spot in her eye. As she stated that she feels nervous and has lost weight, she may have hyperthyroidism, which is making her feel that way and has damaged her eye. The first step to check if hyperthyroidism has caused atrial fibrillation is an ECG.

the plates spread at mid-ocean ridges (they are divergent plate boundaries) which allows magma to rise through the weakness between the plates. the magma then emerges as lava from the boundary and cools, creating a new crust.
