NURSING NR 509 APEA FINAL EXAM HEENT | ADVANCED PHYSIOLOGY | CHAMBERLAIN COLLEGE OF NURSING REAL EXAMS Question 1 The function of the auditory ossicles is to: a. transmit the light reflex to the light cone. b. transform sound vibrations into mechanical waves for the inner ear. c. to capture sound waves from the external ear for transmission into the middle ear. d. to separate the inner ear from the middle ear. Explanation: The function of the auditory ossicles is to transform sound vibrations into mechanical waves for the inner ear Question 2 A 35-year-old patient complains of vertigo accompanied by nausea and vomiting. Examination reveals bilateral diplopia and an unsteady gait. These symptoms could be suggestive of: a. an arrhythmia. b. a neurological condition. c. an inner ear infection. d. orthostatic hypotension. Explanation: Vertigo symptoms associated with neurologic conditions include: ataxia, diplopia, and dysarthria. Symptoms associated with cardiovascular conditions and vertigo include arrhythmias, orthostatic hypotension, vasovagal stimulation, lightheadedness, weakness, or presyncope. Question 3: A 60-year-old was concerned about a yellowish colored lesion above her right eyelid. Findings revealed a slightly raised yellowish, well circumscribed plaque along the nasal area of her right eyelid. This finding is most consistent with: a. a pinguecula. b. a chalazion. c. episcleritis. d. xanthelasma. Explanation: Slightly raised, yellowish, well-circumscribed plaques appearing along the nasal area of one or both eyelids are consistent with lipid disorders and called xanthelasma. Pinguecula refer to harmless, yellowish, triangular nodules in the bulbar conjunctiva on either side of the iris. A chalazion is a nontender nodule usually on the underside of the eyelid. Episcleritis is an ocular inflammation of the episcleral vessels. Question 4 Assessment of a patient's visual acuity resulted in 20/200 using the Snellen eye chart. This means that: a. at 200 feet the patient can read printed information that a person with normal vision could read at 20 feet.
