The physician suspects a client has a dermatological infection. Which of the following diagnostics will be ordered to observe color changes to the skin using an ultraviolet light source?
Culture
KOH
Diascopy
Wood's
The Correct Answer is D
Choice A Reason: Culture is not a diagnostic test that uses an ultraviolet light source, but a laboratory test that involves growing microorganisms from a sample of body fluid or tissue. Culture can help identify the type and sensitivity of the infection-causing agent.
Choice B Reason: KOH is not a diagnostic test that uses an ultraviolet light source, but a chemical test that involves applying potassium hydroxide to a sample of skin, hair, or nail. KOH can help diagnose fungal infections by dissolving the keratin and revealing the fungal elements under a microscope.
Choice C Reason: Diascopy is not a diagnostic test that uses an ultraviolet light source, but a physical test that involves applying pressure to a lesion with a glass slide or lens. Diascopy can help differentiate between blanchable and non-blanchable lesions, such as erythema or petechiae.
Choice D Reason: Wood's is a diagnostic test that uses an ultraviolet light source, also known as a Wood's lamp or black light. Wood's can help observe color changes to the skin that are not visible under normal light, such as fluorescence or hypopigmentation. Wood's can help diagnose conditions such as tinea capitis, vitiligo, or erythrasma.

Correct Answer is A
Explanation
Choice A reason: This is correct because resuming a functional role in society is the ultimate goal for a client in the rehabilitative phase of a burn injury. The rehabilitative phase begins when wound healing is complete and lasts until physical and psychosocial recovery is achieved. The nurse should help the client regain independence, self-esteem, and quality of life by providing education, counseling, referrals, and resources.
Choice B reason: This is incorrect because pain management is not a goal, but an intervention for a client in the rehabilitative phase of a burn injury. Pain management is important throughout all phases of burn care, but especially during wound healing and scar formation, which can cause itching, tightness, or hypersensitivity. The nurse should assess the client's pain level and administer analgesics, antipruritics, or moisturizers as ordered.
Choice C reason: This is incorrect because providing continued full support to the client is not a goal, but an intervention for a client in the rehabilitative phase of a burn injury. Providing continued full support to the client can help them cope with physical and emotional challenges, such as scarring, disfigurement, disability, or depression. The nurse should provide emotional support, active listening, positive feedback, and encouragement to the client.
Choice D reason: This is incorrect because preventing infection is not a goal, but an intervention for a client in the rehabilitative phase of a burn injury. Preventing infection is crucial during wound healing and grafting, which can be compromised by bacterial colonization or contamination. The nurse should monitor the client's vital signs, wound appearance, and laboratory results, and administer antibiotics or antiseptics as ordered.
Correct Answer is A
Explanation
Choice A reason: This is the correct answer because the Amsler grid test is performed to diagnose macular degeneration. The Amsler grid is a pattern of straight lines with a dot in the center. The client is asked to look at the dot and report any distortions or missing areas in the grid. This can indicate damage to the macula, which is the central part of the retina that provides sharp vision.
Choice B reason: This is incorrect because the Snellen chart test is not performed to diagnose macular degeneration. The Snellen chart is a chart of letters of different sizes that are read from a distance. The client is asked to read the smallest line they can see clearly. This can indicate visual acuity or sharpness of vision, but not macular degeneration.
Choice C reason: This is incorrect because the intraocular pressure test is not performed to diagnose macular degeneration. The intraocular pressure test measures the pressure inside the eye using a device called a tonometer. The client may feel a puff of air or a gentle touch on their eye. This can indicate glaucoma, which is a condition where increased pressure damages the optic nerve, but not macular degeneration.
Choice D reason: This is incorrect because the refraction test is not performed to diagnose macular degeneration. The refraction test measures how well the eye bends light rays using a device called a phoropter. The client looks through different lenses and reports which ones make their vision clearer. This can indicate refractive errors such as nearsightedness, farsightedness, or astigmatism, but not macular degeneration.
