A client admitted with an acute exacerbation of Ménière's disease asks the student nurse why he was prescribed diphenhydramine. Which response by the student nurse requires correction by the primary nurse?

Choice A Reason: This is correct because first degree burns are superficial burns that affect only the outer layer of the skin, called the epidermis. First degree burns cause redness, pain, and mild swelling, but no blisters or scarring. They usually heal within a week.

Choice B Reason: This is incorrect because second degree burns are partial thickness burns that affect both the epidermis and the underlying layer of the skin, called the dermis. Second degree burns cause blisters, severe pain, and possible infection. They may take several weeks to heal and may leave scars.

Choice C Reason: This is incorrect because third degree burns are full thickness burns that destroy all layers of the skin and may damage the underlying tissues, such as muscles, nerves, or bones. Third degree burns cause charred or white skin, numbness, and shock. They require skin grafting and may cause permanent disability or death.

Choice D Reason: This is incorrect because this burn can be classified according to the depth and extent of the skin damage. The classification of burns helps to determine the appropriate treatment and prognosis for the client.

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.
