Answer to Question 1

Correct Answer: 1, 5
Narrowing of visual fields may indicate an eye disorder such as glaucoma. Glaucoma may cause displacement of blood vessels from the center of the optic disc due to increased intraocular pressure. Loss of definition of the optic disc is seen in papilledema from increased intracranial pressure. Areas of hemorrhage, exudate, and white patches may be a result of diabetes or longstanding hypertension. Hypertension may cause a narrowing of the vein where an arteriole crosses over.

Answer to Question 2

Correct Answer: 2, 5
Degeneration and atrophy of inner ear structures involved in balance and equilibrium increase the risk for falls. With the loss of high-frequency sounds, speech may be distorted, contributing to a risk for problems with communication. Infection, medication errors, and food intolerance are unrelated to vestibular changes.
