A client receiving parenteral nutrition by central venous access reports feeling unwell. The nurse assesses the client and suspects that the central line has become infected. Which of the following findings indicate that the client has developed a systemic infection? Select all that apply.

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.

Choice A Reason: Slow even breathing is not a sign of Cushing's Triad, which is a late indicator of increased intracranial pressure (ICP). The breathing pattern may be altered due to brainstem compression, but not necessarily slow or even.

Choice B Reason: This is a correct answer because bradycardia and bounding pulse are part of Cushing's Triad, which reflects an increased vagal tone and decreased cardiac output due to increased ICP.

Choice C Reason: Systolic hypotension with a narrowing pulse pressure is not a sign of Cushing's Triad, which involves an increased systolic blood pressure and a widened pulse pressure due to increased ICP. Hypotension may occur due to shock or hemorrhage, but not as a result of increased ICP.

Choice D Reason: This is a correct answer because irregular respirations are part of Cushing's Triad, which reflects impaired respiratory control due to brainstem compression from increased ICP. The respirations may be Cheyne-Stokes, central neurogenic hyperventilation, apneustic, or ataxic.

Choice E Reason: Tachycardia and bounding pulse are not signs of Cushing's Triad, which involves bradycardia and bounding pulse due to increased ICP. Tachycardia may occur due to pain, anxiety, fever, or hypoxia, but not as a result of increased ICP.

Choice F Reason: This is a correct answer because systolic hypertension with a widening pulse pressure are part of Cushing's Triad, which reflects an increased cerebral perfusion pressure due to increased ICP. The diastolic blood pressure remains stable or decreases, resulting in a widened pulse pressure.
