Correct Answer is D
Explanation
Hemorrhagic stroke is a type of stroke that occurs when a blood vessel ruptures in the brain, causing bleeding and increased intracranial pressure. The client's symptoms of sudden, severe headache, vomiting, seizure, and
unresponsiveness are consistent with hemorrhagic stroke. The client's elevated blood pressure and temperature are also risk factors for hemorrhagic stroke.
Thrombotic stroke is a type of stroke that occurs when a blood clot forms in an artery that supplies blood to the brain, causing ischemia and tissue damage. The client's symptoms are not typical of thrombotic stroke, which usually has a gradual onset and affects one side of the body.
Transient ischemic atack (TIA) is a temporary interruption of blood flow to the brain, causing neurologic deficits that resolve within 24 hours. The client's symptoms are not indicative of TIA, which does not cause loss of consciousness or permanent brain damage.
Embolic stroke is a type of stroke that occurs when a blood clot or other debris travels from another part of the body to the brain, causing occlusion and ischemia. The client's symptoms are not characteristic of embolic stroke, which usually has a sudden onset and affects one side of the body.
Correct Answer is ["24"]
Explanation
To calculate the infusion rate, use the formula:
(rate in mL/hr) = (desired dose in units/hr) / (available dose in units/mL)
In this case, the desired dose is 1,200 units/hr and the available dose is 25,000 units / 500 mL = 50 units/mL. Therefore,
(rate in mL/hr) = (1,200 units/hr) / (50 units/mL) = 24 mL/hr
Round the answer to the nearest tenth/whole number and use a leading zero if it applies. Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should set the IV pump to deliver 24 mL/hr.
