A nurse is collecting data from a client who has a subdural hematoma following a motor-vehicle crash. For which of the following findings should the nurse identify that the client is experiencing an increase in intracranial pressure?

Choice A Reason:
Absence of Chvostek's sign is a wrong indication. Chvostek's sign is a twitching of facial muscles in response to tapping the facial nerve and is typically associated with low blood calcium levels (hypocalcemia). It's not directly related to hyperglycemia or high blood sugar levels. Hyperglycemia refers to high blood sugar levels, commonly associated with diabetes mellitus.
Choice B Reason:
Presence of Kussmaul respirations is a right indication. Kussmaul respirations are deep, rapid, and labored breathing patterns often seen in individuals with diabetic ketoacidosis (DKA), a severe complication of diabetes characterized by significantly high blood sugar levels and the presence of ketones in the blood and urine. This type of breathing pattern is the body's attempt to compensate for the acidic state caused by high blood sugar and the buildup of ketones.
Choice C Reason:
Presence of diaphoresis is a wrong indication. Diaphoresis refers to excessive sweating, which can occur due to various reasons such as physical activity, heat, stress, or certain medical conditions. While hyperglycemia can cause symptoms like increased thirst and frequent urination, diaphoresis alone is not a specific indicator of high blood sugar levels.
Choice D Reason:
Absence of urinary ketones is a wrong indication. The presence of urinary ketones indicates the body is breaking down fat for energy, which commonly occurs during periods of insufficient insulin (such as in hyperglycemia or diabetic ketoacidosis). However, the absence of urinary ketones doesn't necessarily rule out hyperglycemia. It's possible for hyperglycemia to be present without ketones in the urine, especially in the early stages or when the body is still managing blood sugar levels without significant ketone production.

Choice A Reason:

Place on airborne precautions. This is incorrect. Tinea corporis isn't transmitted through the air. Airborne precautions are specific infection control measures for diseases transmitted through airborne particles, like tuberculosis or measles, which are caused by specific bacteria or viruses.

Choice B Reason:

Avoid direct contact is correct. Direct contact is a crucial precaution to prevent the spread of tinea corporis. It's a contagious infection, often transmitted through skin-to-skin contact or by sharing contaminated items such as clothing, towels, or bedding. Encouraging precautions like not sharing personal items and avoiding direct skin contact helps prevent the spread of the infection to others.

Choice C Reason:

Isolate for 24 hr. after lesions appear is incorrect. While it's essential to take precautions to prevent spread, isolating for only 24 hours after lesions appear might not be sufficient. The infection can remain contagious until it's effectively treated and lesions have resolved. More extended isolation or precautions might be necessary until the infection is no longer transmissible.

Choice D Reason:

Administer a broad-spectrum antibiotic is incorrect. Tinea corporis is a fungal infection, not a bacterial one, so antibiotics would not be effective against it. Antifungal medications, such as topical or oral antifungals, are the primary treatment for tinea corporis. Using an antibiotic would not treat the fungal infection and might lead to inappropriate medication use.
