A patient with an ischemic stroke has a blood pressure of 200/110 mmHg. Which action should the nurse anticipate?
A) Administering antihypertensives to lower the blood pressure as quickly as possible.
B) Administering antihypertensives if the blood pressure exceeds 220/120 mmHg.
C) Administering antihypertensives to lower blood pressure by 25% over 24 hours.
D) Administering antihypertensives to lower the blood pressure to less than 140/80 mmHg.
B) Administering antihypertensives if the blood pressure exceeds 220/120 mmHg.
