A nurse is assessing a client at a dermatology clinic.
Which of the following findings places the client at risk for developing malignant melanoma?

Choice A rationale

Separation of the retina from the choroid, also known as retinal detachment, is a different condition altogether. Retinal detachment can cause vision loss but is not related to macular degeneration. This condition often requires immediate medical attention to prevent permanent vision loss and is typically characterized by the sudden appearance of floaters, flashes of light, and a shadow or curtain over a portion of the visual field.

Choice B rationale

Peripheral vision loss and seeing halos around light are more commonly associated with conditions like glaucoma. Glaucoma involves increased intraocular pressure, which can damage the optic nerve and lead to peripheral vision loss and seeing halos around lights. This condition can be managed with medications or surgery to lower intraocular pressure and prevent further vision loss.

Choice C rationale

Complaints of severe pain and pressure in the eye are indicative of acute angle-closure glaucoma. This is a medical emergency and requires prompt treatment to reduce intraocular pressure and prevent optic nerve damage. The symptoms of acute angle-closure glaucoma are sudden and severe and can include headache, nausea, and vomiting, along with the eye pain and pressure.

Choice D rationale

Central vision loss with intact peripheral vision is characteristic of macular degeneration, particularly age-related macular degeneration (AMD). AMD affects the macula, the part of the retina responsible for sharp, central vision. As the macula deteriorates, central vision becomes blurry or wavy, making it difficult to read, drive, or recognize faces, while peripheral vision remains largely unaffected.

Choice A rationale

The Romberg test evaluates equilibrium by having the client stand with feet together and eyes closed, observing for swaying or imbalance. It assesses the function of the vestibular system, proprioception, and cerebellar function, making it the most appropriate test for assessing dizziness and equilibrium.

Choice B rationale

The Weber test involves placing a tuning fork on the forehead to evaluate sound lateralization. It assesses hearing loss but not equilibrium, making it less suitable for dizziness assessment.

Choice C rationale

The Rinne test compares air and bone conduction of sound using a tuning fork. While useful for diagnosing conductive hearing loss, it does not assess equilibrium, making it inappropriate for evaluating dizziness.

Choice D rationale

The cover test evaluates eye alignment and muscle function by having the client cover one eye and observe the uncovered eye for movement. It assesses ocular motility but not equilibrium, making it unsuitable for dizziness assessment.
