Final Answer:
The nurse uses an ophthalmoscope to examine the internal structures of the eye, including the retina and optic disc, by illuminating and magnifying them. This aids in assessing eye health and detecting conditions during routine examinations.
Step-by-step explanation:
The instrument that a nurse uses to look at the internal structures of the eye is called an "ophthalmoscope." An ophthalmoscope is a handheld device equipped with a light source and lenses that allow healthcare professionals, including nurses, to examine the retina, optic disc, and other structures within the eye.
An ophthalmoscope is a medical instrument used by healthcare professionals, including nurses, to examine the internal structures of the eye. It consists of a light source and a set of lenses that allow the observer to illuminate and magnify the structures at the back of the eye, such as the retina, optic disc, and blood vessels.
During an eye examination, the nurse uses the ophthalmoscope to assess the health of these structures, check for abnormalities, and detect conditions like retinal disorders, glaucoma, or signs of systemic diseases affecting the eyes. The examination provides valuable information about the overall eye health and helps in early detection and management of eye conditions.
