Chapter 60 Questions
Question 1 of 5
The nurse is caring for a patient who experiences a brief episode of tinnitus, diplopia, and dysarthria with no residual effects. Which of the following actions should the nurse anticipate as treatment for this patient?
Correct Answer: C
Rationale: The patient's symptoms are consistent with transient ischemic attack (TI
A), and drugs that inhibit platelet aggregation are prescribed after a TIA to prevent stroke. Continuous heparin infusion is not routinely used after TIA or with acute ischemic stroke. The patient's symptoms are not consistent with a cerebral aneurysm. tPA is used only for acute ischemic stroke, not for TIA.
Question 2 of 5
The nurse is caring for a patient who has recently experienced a stroke. When reviewing the patients' laboratory report, which of the following results should the nurse report the health care provider?
Correct Answer: B
Rationale: A low platelet count (95,000/?¼L) increases the risk for bleeding and should be reported to the health care provider, especially in the context of stroke management where anticoagulation or antiplatelet therapy may be considered. Normal PaCO2 (35â??45 mm Hg), serum sodium (135â??145 mmol/L), and cholesterol (less than 200 mg/dL is desirable, but 200 mg/dL is not immediately critical) do not require urgent reporting.
Question 3 of 5
The nurse receives a verbal report that a patient has an occlusion of the left posterior cerebral artery. Which of the following findings should the nurse anticipate?
Correct Answer: C
Rationale: Visual disturbances are expected with posterior cerebral artery occlusion. Dysphagia occurs with middle cerebral artery involvement. Cognitive deficits and changes in judgement are more typical of anterior cerebral artery occlusion.
Question 4 of 5
The health care provider prescribes clopidogrel for a patient with cerebral atherosclerosis. Which of the following information should the nurse include when teaching the patient about the new medication?
Correct Answer: B
Rationale: Clopidogrel (Plavix) inhibits platelet function as it increases the risk for 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
The health care provider recommends a carotid endarterectomy for a patient with carotid atherosclerosis and a history of transient ischemic attacks (TIA). The patient asks the nurse to describe the procedure. Which of the following responses by the nurse is appropriate?
Correct Answer: A
Rationale: In a carotid endarterectomy, the carotid artery is incised and the plaque is removed. The response beginning, 'The diseased portion of the artery in the brain is removed' describes an arterial graft procedure. The answer beginning, 'A catheter with a deflated balloon is positioned at the narrow area' describes an angioplasty. The final response beginning, 'A wire is threaded through the artery' describes the MERCI procedure.
