A nurse in a clinic is caring for a client with suspected osteoporosis.
Which of the following assessment findings is the greatest risk factor for the development of this disease?

Choice A rationale

Scleroderma typically causes a thickening and hardening of the skin, known as sclerodactyly, rather than thinning. The pathophysiology involves the excessive deposition of collagen in the dermis and subcutaneous tissues. This overproduction leads to skin that feels tight, bound down, and loses its natural elasticity. Thinning of the skin is more commonly associated with chronic corticosteroid use or natural aging rather than the fibrotic process that defines the progression of systemic or localized scleroderma.

Choice B rationale

Clients with scleroderma often suffer from xerostomia, which is extreme dryness of the mouth, rather than excessive salivation. This occurs because the fibrotic process can affect the salivary glands, reducing their ability to produce adequate moisture. Furthermore, many scleroderma patients also have secondary Sjogren syndrome, which further decreases glandular secretions. Excessive salivation would be an unusual finding and is not a clinical marker for the progression of the connective tissue fibrosis seen in this disease.

Choice C rationale

While some facial changes occur in scleroderma, such as a mask like appearance or restricted mouth opening, periorbital edema is not a standard expectation. Periorbital edema is more frequently associated with renal failure, nephrotic syndrome, or inflammatory conditions like dermatomyositis. In scleroderma, the skin around the eyes is more likely to become tight and taut due to collagen accumulation. The fibrotic nature of the disease usually results in tissue contraction and firmness rather than fluid accumulation.

Choice D rationale

Decreased range of motion is a common finding in scleroderma due to the hardening of the skin and fibrosis of the underlying connective tissues and tendons. As the skin becomes increasingly tight and rigid, it restricts the movement of the joints beneath it. This contracture development significantly impacts the functional mobility of the hands and limbs. Assessing for joint flexibility is essential to document disease progression as the fibrosis moves from the skin into deeper musculoskeletal structures.

Choice A rationale

A refraction test is used to determine a client optical prescription for eyeglasses or contact lenses. It involves the use of a phoropter to measure how light waves are bent as they pass through the cornea and lens. This test identifies refractive errors like myopia, hyperopia, and astigmatism. It does not provide information about the health of the retina or the presence of maculopathy, which is the primary concern in cases of suspected macular degeneration.

Choice B rationale

The Snellen chart is the standard tool for measuring distance visual acuity. It requires a client to read letters of decreasing size from a distance of 20 feet. While it can detect a general decline in vision, it is not specific to macular degeneration. A client with maculopathy might still have relatively good peripheral vision but struggle with central tasks. The Snellen chart evaluates overall clarity but lacks the precision needed to identify central scotomas.

Choice C rationale

The Amsler grid is a diagnostic tool consisting of a grid of horizontal and vertical lines used specifically to monitor the central visual field. Clients with macular degeneration will report that the lines appear wavy, distorted, or missing, a phenomenon known as metamorphopsia. Because the macula is responsible for sharp, central vision, this test is the most sensitive and appropriate bedside or clinic tool for detecting early changes and progression of this specific retinal condition.

Choice D rationale

Intraocular pressure measurement, typically performed via tonometry, is the gold standard for screening and monitoring glaucoma. Normal intraocular pressure ranges from 10 to 21 mmHg. Elevated pressure can lead to optic nerve damage, but it is not a diagnostic marker for macular degeneration. Macular degeneration is a disease of the retinal tissue itself, often related to aging and oxidative stress, rather than the fluid pressure dynamics inside the anterior chamber.
