The nurse is caring for a client who had a thrombotic stroke in the Emergency Department. It has been less than 3 hours since the onset of symptoms. The rationale for using tissue plasminogen activator (t-PA) for this client is to:
reduce the risk of blood vessel spasm.
prevent platelet aggregation.
dissolve the blood clot.
prevent infection in the brain.
The Correct Answer is C
A. While blood vessel spasms can occur after a stroke, t-PA does not directly affect them.
B. Platelet aggregation is the process by which platelets stick together to form a clot. t-PA dissolves clots, but it does not prevent their formation.
C. Tissue plasminogen activator (t-PA) is a medication that can dissolve blood clots. In the case of a thrombotic stroke, a blood clot has blocked blood flow to the brain. By dissolving the clot, t-PA can restore blood flow and limit brain damage.
D. t-PA does not have any direct effect on the risk of infection in the brain.

Correct Answer is B
Explanation
A. A negative output would imply that the client has produced less urine than the irrigation received, which is not the case here.
B. The true urine output is 675 mL, calculated by subtracting the irrigation amount from the total urine collected.
C. The calculation does not support this value, as it does not accurately reflect the total urine output after accounting for the irrigation.
D. Similar to option A, a negative value does not apply here since the urine output exceeds the irrigation amount.
Correct Answer is B
Explanation
A. Clopidogrel is not a pain medication; it is an antiplatelet agent used to reduce the risk of stroke and other cardiovascular events. It should be taken regularly, not on an as-needed basis.
B. Clopidogrel works by inhibiting platelet aggregation, which helps prevent the formation of blood clots that can lead to strokes. This understanding indicates that the client recognizes the purpose of the medication and its importance in managing their condition after a TIA.
C. Clopidogrel is not used to treat anxiety; it is primarily focused on reducing the risk of thrombotic events. This choice shows a misunderstanding of the medication's purpose.
D. Clopidogrel does not directly control blood pressure; it is used to prevent blood clots. While blood pressure management is essential in the context of stroke prevention, clopidogrel itself does not have a role in lowering blood pressure.
