Question 4 of 5
When teaching about clopidogrel (Plavix), the nurse will tell the patient with cerebral atherosclerosis
Correct Answer: B
Rationale: Clopidogrel inhibits platelet function and increases the risk for gastrointestinal bleeding, so patients should be advised to notify the health care provider about any signs of bleeding. The medication does not lower blood pressure, decrease plaque formation, or dissolve clots.
Question 5 of 5
Which information about the patient who has had a subarachnoid hemorrhage is most important to communicate to the health care provider?
Correct Answer: B
Rationale: To prevent cerebral vasospasm and maintain cerebral perfusion, BP needs to be maintained at a level higher than $90 \mathrm{~mm} \mathrm{Hg}$ systolic after a subarachnoid hemorrhage. A low BP or drop in BP indicates a need to administer fluids and/or vasopressors to increase the BP. An ongoing headache, RBCs in the CSF, and a stiff neck are all typical clinical manifestations of a subarachnoid hemorrhage and do not need to be rapidly communicated to the health care provider.
