Question 4 of 5
A patient admitted with possible stroke has been aphasic for 3 hours, and his current blood pressure (BP) is 174/94 mm Hg. Which order by the health care provider should the nurse question?
Correct Answer: C
Rationale: Because elevated BP may be a protective response to maintain cerebral perfusion, antihypertensive therapy is recommended only if mean arterial pressure (MAP) is greater than $130 mm Hg or systolic pressure is greater than $220 mm Hg. Fluid intake should be 1500 to $2000 mL/day to maintain cerebral blood flow. The head of the bed should be elevated to at least 30 degrees unless the patient has symptoms of poor tissue perfusion. tPA may be administered if the patient meets the other criteria for tPA use.
Question 5 of 5
After receiving change-of-shift report on the following four patients, which patient should the nurse see first?
Correct Answer: A
Rationale: tPA needs to be infused within the first few hours after stroke symptoms start in order to be effective in minimizing brain injury. The other medications should also be given as quickly as possible, but timing of the medications is not as critical.
