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: This is incorrect because turning off the lights and TV and closing the door may increase the client's anxiety and confusion. The nurse should provide adequate lighting and familiar objects to help orient the client.
Choice B Reason: This is incorrect because using restraints may increase the risk of injury, infection, and psychological distress for the client. The nurse should use restraints only as a last resort and with a physician's order.
Choice C Reason: This is incorrect because asking for a sedative may not address the underlying cause of the agitation. The nurse should use non-pharmacological interventions first, such as calming music, massage, or aromatherapy.
Choice D Reason: This is correct because identifying the cause of the agitation may help resolve it. The nurse should assess for possible triggers, such as pain, hunger, thirst, infection, or environmental factors.
Correct Answer is D
Explanation
Choice A Reason: To administer medications and electrolytes is not the best reply for why the client will need the NG tube, because this is not the primary purpose of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. Medications and electrolytes can be given through the IV route.
Choice B Reason: To dilate the stomach as a presurgical preparation is not the best reply for why the client will need the NG tube, because this is not a valid indication for the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. Dilation of the stomach is not a goal of presurgical preparation, but rather an adverse effect of gastric obstruction.
Choice C Reason: You will not be able to eat for several days is not the best reply for why the client will need the NG tube, because this is not a complete or accurate explanation of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. The client will not be able to eat for several days because of the NPO diet, which is necessary to rest the inflamed peritoneum and reduce the risk of complications.
Choice D Reason: To remove secretions and decompress your stomach is the best reply for why the client will need the NG tube, because this is a clear and correct explanation of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration, which are common symptoms of acute peritonitis. By removing secretions and decompressing the stomach, the NG tube can reduce pain, inflammation, and infection in the abdominal cavity.
