The nurse is speaking to the client and suspects a weakness in eye muscle after observing the eyes cross.What test should the nurse administer to further assess this problem?

Choice A rationaleThe Cover/Uncover test is used to assess the presence of strabismus or eye muscle weakness. During this test, one eye is covered while the other eye is observed for movement. The uncovered eye is then observed when the cover is removed. If there is a misalignment or weakness, the uncovered eye will move to re-establish focus, indicating a problem with eye muscle control.Choice B rationaleTesting peripheral vision involves assessing the range of vision around the central focus point and is not specifically used to detect eye muscle weakness. It evaluates the function of the retina and optic nerve rather than the eye muscles. This test helps identify issues such as glaucoma or retinal detachment.Choice C rationaleThe Snellen chart test measures visual acuity, specifically how well a person can see at various distances. It is not designed to assess eye muscle strength or alignment. The test involves reading letters of different sizes from a chart placed at a standard distance.Choice D rationaleThe Weber test is an auditory test used to assess hearing loss by placing a vibrating tuning fork on the forehead or middle of the head. It helps determine whether hearing loss is conductive or sensorineural in nature. This test does not provide information about eye muscle function or alignment.
