A 66-year-old client weighing 80 kg arrives at the emergency department 40 minutes after family saw the sudden onset of right arm and leg weakness, right facial droop that spares the forehead, and slurred speech. The client has no history of seizures, no seizure activity was witnessed, and the client takes no anticoagulants. Capillary glucose is 112 mg/dL (6.2 mmol/L). Blood pressure is 192/104 mm Hg, heart rate 92/min and irregular, and oxygen saturation 97% on room air. The NIH Stroke Scale score is 9 and has not changed over 20 minutes. A noncontrast head CT completed 15 minutes after arrival shows no hemorrhage. The provider has determined the client is a candidate for IV thrombolysis. Complete the diagram by selecting the condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to assess the client's progress.

Quick answer
Acute ischemic stroke; give prescribed IV labetalol to bring pressure below 185/110 mm Hg and prepare the prescribed IV thrombolytic, then monitor the NIH Stroke Scale score and blood pressure every 15 minutes.

Why this is correct
The deficit is persistent with an NIH Stroke Scale score of 9, the glucose is normal, and CT excludes hemorrhage. The client is a thrombolysis candidate, but a blood pressure of 192/104 mm Hg exceeds the limit for safe thrombolysis, so it must be lowered first. After treatment, frequent neurologic and blood pressure checks detect bleeding and pressure excursions early.

Easy analogy or mental picture
Picture a blocked pipe you want to flush: before opening the valve, lower the pressure so the weakened pipe wall does not burst.

Memory hook
Clot on CT? No bleed → lower BP under 185/110 → then thrombolyse; watch NIHSS and BP.

NCLEX decision rule
When a time-sensitive treatment has a safety threshold, choose the action that makes the client eligible now plus the treatment itself, then monitor the values that signal its main complication.

Why the other choices are wrong
A transient ischemic attack resolves; this deficit is unchanged at 40 minutes with a score of 9, so it is managed as a stroke. Todd paralysis follows a seizure, and none occurred, so lorazepam and a phenytoin level do not apply. Bell palsy involves the forehead and does not cause arm weakness or dysarthria. Aspirin is withheld for 24 hours after thrombolysis and requires a swallow screen. A systolic target below 140 mm Hg is used for intracerebral hemorrhage and would lower cerebral perfusion here. aPTT monitors heparin therapy, and hourly glucose checks are less specific once glucose is normal.
