A nurse in the emergency department is caring for a client who has sustained a head injury. The nurse notes the client's IV fluids are infusing at 125 mL/hr. Which of the following is an appropriate action by the nurse?
Slow the rate to 50 mL/hr.
Increase the rate to 250 mL/hr.
Slow the rate to 20 mL/hr.
Continue the rate at 125 mL/hr.
The Correct Answer is C
Choice A Reason: This choice is incorrect because slowing the rate to 50 mL/hr may not be enough to prevent cerebral edema, which is a common complication of head injury. Cerebral edema is a swelling of the brain tissue due to increased fluid accumulation. It can cause increased intracranial pressure (ICP), which can lead to brain damage or death. Therefore, the nurse should limit the fluid intake of the client with head injury to avoid worsening the condition.
Choice B Reason: This choice is incorrect because increasing the rate to 250 mL/hr may cause fluid overload, which can also increase the ICP and worsen the cerebral edema. Fluid overload is a condition in which the body has too much fluid, which can impair the function of the heart, lungs, and kidneys. Therefore, the nurse should avoid giving too much fluid to the client with head injury.
Choice C Reason: This choice is correct because slowing the rate to 20 mL/hr may help to maintain adequate hydration and electrolyte balance, while preventing fluid overload and cerebral edema. This is a conservative approach that can be used until the client's neurological status and ICP are assessed and monitored.
Choice D Reason: This choice is incorrect because continuing the rate at 125 mL/hr may not be appropriate for the client with head injury, depending on their individual needs and condition. The nurse should adjust the fluid rate according to the client's vital signs, urine output, serum osmolality, and ICP. Therefore, the nurse should not assume that this rate is optimal for the client without further evaluation.

Correct Answer is C
Explanation
Choice A Reason: Albumin 25% is not a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Albumin 25% is a colloid solution that increases the oncotic pressure and draws fluid from the interstitial space into the intravascular space, which can worsen the intracranial pressure by increasing the cerebral blood flow and edema.
Choice B Reason: Dextran 70 is not a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Dextran 70 is a plasma expander that increases the blood volume and viscosity, which can also worsen the intracranial pressure by increasing the cerebral blood flow and edema.
Choice C Reason: Mannitol 25% is a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Mannitol 25% is an osmotic diuretic that reduces the intracranial pressure by creating an osmotic gradient and drawing fluid from the brain tissue into the blood vessels, which can then be excreted by the kidneys. The nurse should monitor the urine output, serum osmolality, and electrolytes when administering mannitol 25%.
Choice D Reason: Hydroxyethyl starch is not a medication that the nurse should plan to administer for a client who is experiencing Cushing's triad following a subdural hematoma. Hydroxyethyl starch is another plasma expander that has similar effects as dextran 70, and can also increase the risk of coagulopathy and renal failure.
Correct Answer is C
Explanation
Choice A Reason: This is incorrect because hypertension is a condition of high blood pressure. A client who has hypovolemic shock is more likely to have hypotension, which is a condition of low blood pressure, due to fluid loss and reduced cardiac output.
Choice B Reason: This is incorrect because bradypnea is a condition of slow breathing. A client who has hypovolemic shock is more likely to have tachypnea, which is a condition of fast breathing, due to hypoxia and increased respiratory demand.
Choice C Reason: This is correct because oliguria is a condition of low urine output. A client who has hypovolemic shock may have oliguria due to decreased renal perfusion and activation of the renin-angiotensin-aldosterone system, which causes sodium and water retention.
Choice D reason: This is incorrect because flushing of the skin is a condition of redness and warmth of the skin. A client who has hypovolemic shock may have pallor and coolness of the skin due to vasoconstriction and reduced blood flow.
