A nurse is preparing to administer an osmotic diuretic IV to a client with increased intracranial pressure. Which of the following should the nurse identify as the purpose of the medication?

Choice A Reason: Cause of the burn is not the nurse's priority when assessing the severity of the client's burns. The cause of the burn may indicate the type and duration of exposure, such as thermal, chemical, electrical, or radiation, which can affect the depth and extent of injury. However, these factors are secondary to ensuring adequate oxygenation and ventilation.

Choice B Reason: Age of the client is not the nurse's priority when assessing the severity of the client's burns. The age of the client may influence the response to burn injury, such as healing time, infection risk, and fluid requirements.

However, these factors are secondary to ensuring adequate oxygenation and ventilation.

Choice C Reason: Associated medical history is not the nurse's priority when assessing the severity of the client's burns. The associated medical history may affect the outcome and prognosis of burn injury, such as pre-existing conditions, medications, or allergies. However, these factors are secondary to ensuring adequate oxygenation and ventilation.

Choice D Reason: Location of the burn is the nurse's priority when assessing the severity of the client's burns. The location of the burn can indicate the potential for life-threatening complications, such as airway obstruction, inhalation injury, or impaired circulation. The nurse should assess for signs and symptoms of respiratory distress, such as stridor, wheezes, or cyanosis, and prepare for endotracheal intubation if needed. The nurse should also monitor for signs and symptoms of compartment syndrome, such as pain, pallor, paresthesia, pulselessness, or paralysis, and report any findings to the provider. The location of the burn can also affect the functional and cosmetic outcomes, such as vision loss, facial disfigurement, or joint contractures. The nurse should provide appropriate wound care, pain management, and rehabilitation as prescribed. Assessing for location of burn is essential to prevent further injury and preserve vital functions.

Choice A Reason: This choice is incorrect because hypomagnesemia is not a common finding in the oliguric phase of acute kidney injury. Hypomagnesemia is a condition in which the serum magnesium level is lower than normal (less than 1.5 mEq/L). It may be caused by various factors such as malnutrition, diarrhea, diuretics, or alcohol abuse. It may cause symptoms such as muscle weakness, tremors, tetany, or cardiac arrhythmias.

Choice B Reason: This choice is correct because hyperkalemia is a common finding in the oliguric phase of acute kidney injury. Hyperkalemia is a condition in which the serum potassium level is higher than normal (more than 5 mEq/L). It may be caused by reduced renal excretion of potassium due to decreased urine output (oliguria). It may cause symptoms such as muscle weakness, paresthesia, bradycardia, or cardiac arrest.

Choice C Reason: This choice is incorrect because decreased creatinine level is not a common finding in the oliguric phase of acute kidney injury. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys and excreted in urine. A normal creatinine level ranges from 0.6 to 1.2 mg/dL for men and 0.5 to 1.1 mg/dL for women. In acute kidney injury, creatinine level usually increases due to reduced renal function and impaired clearance of creatinine.

Choice D Reason: This choice is incorrect because increased glomerular filtration rate (GFR) is not a common finding in the oliguric phase of acute kidney injury. GFR is a measure of how well

the kidneys filter blood and remove waste products.

A normal GFR range is 90,to 120 mL/min/1.73 m2. In acute kidney injury, GFR usually decreases due to reduced blood flow,to,the kidneys or damage to the glomeruli, which are the tiny blood vessels that filter blood in the kidneys.
