Quiz 6 Question 1 1 / 1 pts A client with hyperthyroidism presents with a complaint of a feeling in her eyes. Over the past week, her visual acuity has diminished, and her ability to see colors ... has changed. She also has a feeling of pressure behind her eyes.

This is an emergency situation that may require hospitalization and treatment with prednisone to diminish the inflammation. Artificial tears are also helpful.
