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","B","C","D","E"]
Explanation
Choice A Reason: This is correct because clinical obesity is a risk factor for metabolic syndrome. Clinical obesity is defined by having a body mass index (BMI) of 30 or higher, or a waist circumference of more than 40 inches for men or 35 inches for women. Obesity can increase insulin resistance and inflammation, which can lead to metabolic syndrome.
Choice B Reason: This is correct because elevated blood pressure is a risk factor for metabolic syndrome. Elevated blood pressure is defined by having a systolic blood pressure of 130 mm Hg or higher, or a diastolic blood pressure of 85 mm Hg or higher. High blood pressure can damage the blood vessels and increase the risk of cardiovascular disease, which is associated with metabolic syndrome.
Choice C Reason: This is correct because high triglycerides are a risk factor for metabolic syndrome. Triglycerides are a type of fat that circulates in the blood and provides energy for the cells. High triglycerides are defined by having a level of 150 mg/dL or higher. High triglycerides can increase the risk of fatty liver disease and pancreatitis, which are related to metabolic syndrome.
Choice D Reason: This is correct because hypercholesterolemia is a risk factor for metabolic syndrome. Hypercholesterolemia is defined by having a total cholesterol level of 200 mg/dL or higher, or a low-density lipoprotein (LDL) cholesterol level of 100 mg/dL or higher. LDL cholesterol is also known as "bad" cholesterol because it can build up in the arteries and cause plaque formation and narrowing, which can lead to cardiovascular disease and metabolic syndrome.
Choice E Reason: This is correct because hyperglycemia is a risk factor for metabolic syndrome. Hyperglycemia is defined by having a fasting blood glucose level of 100 mg/dL or higher, or a hemoglobin A1c level of 5.7% or higher. Hemoglobin A1c is a measure of average blood glucose over three months. Hyperglycemia can indicate impaired glucose metabolism and insulin resistance, which are hallmarks of metabolic syndrome.
Correct Answer is D
Explanation
Choice A reason: This is incorrect because this comment does not require reporting to the client's provider. It is normal to have reduced vision and an increased risk of falling with a patch on one eye after cataract surgery. The nurse should reassure the client, provide assistance with mobility, and educate the client on safety measures.
Choice B reason: This is incorrect because this comment does not require reporting to the client's provider. It is normal to have some itching and discomfort in the eye after cataract surgery. The nurse should commend the client for not rubbing the eye, as this can cause infection or damage to the surgical site. The nurse should also administer anti-inflammatory eye drops as prescribed and instruct the client on how to apply them.
Choice C reason: This is incorrect because this comment does not require reporting to the client's provider. It is normal to have increased sensitivity to light in the eye after cataract surgery. The nurse should dim the lights in the room, provide sunglasses or a shield for the eye, and educate the client on how to protect the eye from bright light.
Choice D reason: This is the correct answer because this comment requires reporting to the client's provider. Severe pain in the eye after cataract surgery can indicate a complication such as infection, inflammation, bleeding, or increased intraocular pressure. The nurse should assess the eye for signs of redness, swelling, discharge, or bleeding, and report the findings and the pain level to the provider. The nurse should also administer analgesics as prescribed and monitor the pain relief.
