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 D
Explanation
Choice A Reason: A heart rate of 122/min is elevated, but not life-threatening. It could be due to pain, anxiety, dehydration, or infection.
Choice B Reason: A urinary output of 25 ml/hr is low, but not critical. It could indicate fluid loss, kidney damage, or inadequate fluid resuscitation.
Choice C Reason: A pain level of 6 on a scale of 0 to 10 is moderate, but not severe. It could be managed with analgesics and non-pharmacological interventions.
Choice D Reason: This is the correct answer because difficulty swallowing can indicate airway obstruction, inhalation injury, or edema of the throat. It can compromise breathing and require immediate intervention.
Correct Answer is D
Explanation
Choice A Reason: Providing written materials and visual aids is not necessary for a client who has hearing at 15 dB, which is considered normal hearing. Normal hearing ranges from 0 to 20 dB, meaning that the person can hear sounds that are as faint as 20 dB or less.
Choice B Reason: Using American Sign Language is not appropriate for a client who has hearing at 15 dB, which is considered normal hearing. American Sign Language is a form of communication that uses hand gestures, facial expressions, and body movements to convey meaning. It is mainly used by people who are deaf or hard of hearing.
Choice C Reason: Shouting at the client from 6 inches away is not advisable for a client who has hearing at 15 dB, which is considered normal hearing. Shouting can be perceived as rude or aggressive, and can damage the hearing of both the speaker and the listener.
Choice D Reason: Speaking to the client in an everyday conversational tone is the best action for a client who has hearing at 15 dB, which is considered normal hearing. Conversational speech ranges from 40 to 60 dB, meaning that the person can hear sounds that are as loud as 60 dB or less.
