ATI HEALTH ASSESSMENT FINAL EXAM 3 LATEST VERSIONS (VERSION A, B AND C) NEWEST 2024 ACTUAL EXAM 400 QUWESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES (VERIFIED ANSWERS) | ALREADY GRADED A+ ATI HEALTH ASSESSMENT VERSION A A nurse is examining the eyes of a client who has complained of having a feeling of a foreign body in his eye. The nurse examines the thin, transparent, continuous membrane that lines the inside of the eyelids and covers most of the anterior eye. The nurse recognizes this membrane as which of the following? a) Cornea b) Conjunctiva c) Retina d) Sclera - ...ANSWER...Conjunctiva Explanation: The conjunctiva is a thin, transparent, continuous membrane that is divided into two portions: a palpebral and a bulbar portion. The palpebral conjunctiva lines the inside of the eyelids, and the bulbar conjunctiva covers most of the anterior eye, merging with the cornea at the limbus. The innermost layer, the retina, extends only to the ciliary body anteriorly. It receives visual stimuli and sends them to the brain. The sclera is a dense, protective, white covering that physically supports the internal structures of the eye. The transparent cornea (the "window of the eye") permits the entrance of light, which passes through the lens to the retina. Which of the following findings should a doctor expect to note when assessing the six cardinal fields of gaze? a. The presence of nystagmus in all fields b. Symmetrical corneal light reflex c. Presence of the red reflex d. Smooth, coordinated movement of the eyes - ...ANSWER... EXPLANATION: Smooth, coordinated movement of the eyes-the six cardinal fields test eye movements and the muscle of the eye. normal findings include smooth, coordinated movement of the eyes with occasional mild nystagmus (jerking) in extreme lateral gaze. nystagmus in all six fields is an abnormal finding that requires further evaluation. a symmetrical corneal light reflex is the expected response of the corneal light reflex test. the red reflex is assessed when using the ophthalmoscope. A nurse is presenting a class to a local community group about vision and eye health. As part of the presentation, the nurse explains how visual perception occurs. Which of the following would the nurse include in the explanation? a) It primarily involves the lens of the eye. b) It allows the eyes to focus on near objects. c) It begins with light rays striking the retina. d) It refers to a client's subjective appraisal of his or her vision. - ...ANSWER...It begins with light rays striking the retina. Explanation: Visual perception occurs as light rays strike the retina, where they are transformed into nerve impulses, conducted to the brain through the optic nerve, and interpreted. The lens does not contribute directly to visual perception. Accommodation is the process that allows the eyes to focus on near objects. The nurse is conducting a visual examination. Which of these statements regarding visual pathways and visual fields is true? a.The right side of the brain interprets the vision for the right eye. b.The image formed on the retina is upside down and reversed from its actual appearance in the outside world. c.Light rays are refracted through the transparent media of the eye before striking the pupil. d.Light impulses are conducted through the optic nerve to the temporal lobes of the brain. - ...ANSWER...B RATIONALE: The image formed on the retina is upside down and reversed from its actual appearance in the outside world. The light rays are refracted through the transparent media of the eye before striking the retina, and the nerve impulses are conducted through the optic nerve tract to the visual cortex of the occipital lobe of the brain. The left side of the brain interprets vision for the right eye. A patient has a normal pupillary light reflex. The nurse recognizes that this reflex indicates that: a.The eyes converge to focus on the light. b.Light is reflected at the same spot in both eyes. c.The eye focuses the image in the center of the pupil. d.Constriction of both pupils occurs in response to bright light. - ...ANSWER...D EXPLANATION: The pupillary light reflex is the normal constriction of the pupils when bright light shines on the retina. The other responses are not correct. In using the ophthalmoscope to assess a patient's eyes, the nurse notices a red glow in the patient's pupils. On the basis of this finding, the nurse would: a.Suspect that an opacity is present in the lens or cornea. b.Check the light source of the ophthalmoscope to verify that it is functioning. c.Consider the red glow a normal reflection of the ophthalmoscope light off the inner retina. d.Continue with the ophthalmoscopic examination, and refer the patient for further evaluation. - ...ANSWER...C EXPLANATION: The red glow filling the person's pupil is the red reflex and is a normal finding caused by the reflection of the ophthalmoscope light off the inner retina. The other responses are not correct. The nurse is examining a patient's retina with an ophthalmoscope. Which finding is considered normal? a.Optic disc that is a yellow-orange color b.Optic disc margins that are blurred around the edges c.Presence of pigmented crescents in the macular area d.Presence of the macula located on the nasal side of the retina - ...ANSWER...A RATIONALE: The optic disc is located on the nasal side of the retina. Its color is a creamy yellow-orange to a pink, and the edges are distinct and sharply demarcated, not blurred. A pigmented crescent is black and is due to the accumulation of pigment in the choroid. When performing the corneal light reflex assessment, the nurse notes that the light is reflected at 2 o'clock in each eye. The nurse should: a.Consider this a normal finding. b.Refer the individual for further evaluation.
