A nurse is caring for a client who has a traumatic head injury and is exhibiting signs of increasing intracranial pressure. Which of the following medications should the nurse plan to administer?
Dextran 70
Hydroxyethyl starch
Albumin 25%
Mannitol 25%
The Correct Answer is D
Choice A Reason: Dextran 70 is not a medication that the nurse should plan to administer for a client who has a traumatic head injury and is exhibiting signs of increasing intracranial pressure. Dextran 70 is a plasma expander that increases the blood volume and viscosity, which can worsen the intracranial pressure by increasing the cerebral blood flow and edema.
Choice B Reason: Hydroxyethyl starch is not a medication that the nurse should plan to administer for a client who has a traumatic head injury and is exhibiting signs of increasing intracranial pressure. Hydroxyethyl starch is another plasma expander that has similar effects as dextran 70, and can also increase the risk of coagulopathy and renal failure.
Choice C Reason: Albumin 25% is not a medication that the nurse should plan to administer for a client who has a traumatic head injury and is exhibiting signs of increasing intracranial pressure. Albumin 25% is a colloid solution that increases the oncotic pressure and draws fluid from the interstitial space into the intravascular space, which can also worsen the intracranial pressure by increasing the cerebral blood flow and edema.
Choice D Reason: Mannitol 25% is a medication that the nurse should plan to administer for a client who has a traumatic head injury and is exhibiting signs of increasing intracranial pressure. 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%.

Correct Answer is ["125"]
Explanation
Step 1: Determine the total time required to infuse 40 mEq at a rate of 10 mEq/hr.
40 mEq ÷ 10 mEq/hr = 4 hours
Result: 4 hours
Step 2: Determine the infusion rate in mL/hr.
500 mL ÷ 4 hours = 125 mL/hr
Result: 125 mL/hr
The nurse should set the IV pump to deliver 125 mL/hr.
Correct Answer is D
Explanation
Choice A Reason: This is incorrect because crepitus in the area above and surrounding the insertion site is not a serious finding that requires notification of the provider. Crepitus is a crackling sensation that occurs when air leaks into the subcutaneous tissue. It is usually harmless and resolves on its own.
Choice B reason: This is incorrect because bubbling of the water in the water seal chamber with exhalation is a normal finding that indicates that air is being removed from the pleural space. Bubbling should stop when the pneumothorax is resolved.
Choice C Reason: This is incorrect because eyelets are not visible is not a serious finding that requires notification of the provider. Eyelets are small holes at the end of the chest tube that allow air and fluid to drain from the pleural space. They are usually covered by a dressing and may not be visible.
Choice D Reason: This is correct because movement of the trachea toward the unaffected side is a serious finding that indicates a tension pneumothorax, which is a life-threatening condition that occurs when air accumulates in the pleural space and causes pressure on the mediastinum. The nurse should notify the provider immediately and prepare for needle decompression or chest tube insertion.
