Final answer:
The goal BP before giving lytics for an ischemic CVA is to maintain a balance between adequate blood flow to the brain and minimizing the risk of bleeding. The target BP range may vary depending on the individual patient. If the patient is not receiving lytics, a more conservative BP goal is typically followed to reduce the risk of bleeding.
Step-by-step explanation:
The goal blood pressure (BP) before giving lytics, or clot-dissolving medication, for a patient with an ischemic CVA, or stroke caused by a blockage in the blood vessels supplying the brain, is to maintain the BP within a target range that balances the need for adequate blood flow to the brain while minimizing the risk of bleeding. The specific target BP may vary depending on the individual patient, but typically the systolic pressure should be maintained below 180 mmHg and the diastolic pressure below 110 mmHg.
If the patient is not receiving lytics, the goal BP may be more conservative in order to reduce the risk of bleeding. In this case, the systolic pressure should generally be maintained below 140 mmHg and the diastolic pressure below 90 mmHg, according to the recommended guidelines.
