A nurse is caring for a client who is experiencing Cushing's triad following a subdural hematoma. Which of the following medications should the nurse plan to administer?
Albumin 25%
Dextran 70
Mannitol 25%
Hydroxyethyl starch
The Correct Answer is C
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 A
Explanation
Choice A Reason: This choice is correct because allowing the drainage to drip onto a sterile gauze pad may help to identify if it is cerebrospinal fluid (CSF), which is a clear fluid that surrounds and protects the brain and spinal cord. CSF leakage from the nose (rhinorrhea) may indicate a basilar skull fracture, which is a serious injury that can cause intracranial bleeding, infection, or brain damage. The nurse should test the drainage for the presence of glucose or the halo sign, which are indicators of CSF.
Choice B Reason: This choice is incorrect because obtaining a culture of the specimen using sterile swabs may introduce bacteria into the nasal cavity and increase the risk of infection. The nurse should avoid inserting anything into the nose or mouth of a client who has a suspected basilar skull fracture.
Choice C Reason: This choice is incorrect because inserting sterile packing into the nares may increase the pressure in the cranial cavity and worsen the injury. The nurse should avoid applying pressure or occluding the nose or ears of a client who has a suspected basilar skull fracture.
Choice D Reason: This choice is incorrect because suctioning the nose gently with a bulb syringe may damage the nasal mucosa and cause bleeding. The nurse should avoid suctioning or irrigating the nose or ears of a client who has a suspected basilar skull fracture.
Correct Answer is ["24"]
Explanation
- To find the concentration of heparin in the solution, divide the amount of heparin by the volume of D5W: 25,000 units / 500 mL = 50 units/mL
- To find the infusion rate, divide the prescribed dose by the concentration: 1,200 units/hr / 50 units/mL = 24 mL/hr
- Round the answer to the nearest tenth/whole number: 24 mL/hr
