Nokea
The nurse is receiving a change-of-shift report. Which of the following patients should the nurse see first?
- A. A patient with right-sided weakness who has an infusion of tPA prescribed
- B. A patient who has atrial fibrillation and a new prescription for warfarin
- C. A patient who experienced a transient ischemic attack yesterday who has a dose of Aspirin due
- D. A patient with a subarachnoid hemorrhage 2 days ago who has nimodipine scheduled
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 also should be given as quickly as possible, but timing of the medications is not as critical.

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?
- A. Dysphagia
- B. Confusion
- C. Visual deficits
- D. Poor judgement
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.
The nurse is caring for a patient with sudden-onset right-sided weakness who has a CT scan and is diagnosed with an intracerebral hemorrhage. Which of the following information about the patient is most important to communicate to the health care provider?
- A. The patient's speech is difficult to understand.
- B. The patient's blood pressure is 144/90 mm Hg.
- C. The patient takes a diuretic because of a history of hypertension.
- D. The patient has atrial fibrillation and takes warfarin.
Correct Answer: D
Rationale: The use of warfarin will have contributed to the intracerebral bleeding and remains a risk factor for further bleeding. Administration of vitamin K is needed to reverse the effects of the warfarin, especially if the patient is to have surgery to correct the bleeding. The history of hypertension is a risk factor for the patient but has no immediate effect on the patient's care. The BP of 144/90 indicates the need for ongoing monitoring but not for any immediate change in therapy. Slurred speech is consistent with a left-sided stroke, and no change in therapy is indicated.
The nurse is caring for a patient who had a stroke and is in the acute phase of care. Which of the following systems is priority?
- A. Neurological system
- B. Respiratory system
- C. Gastro-intestinal system
- D. Genito-urinary system
Correct Answer: B
Rationale: During the acute phase following a stroke, management of the respiratory system is a nursing priority. Stroke patients are particularly vulnerable to respiratory problems as it has been shown that respiratory muscle strength decreases following stroke. Advancing age and immobility increase the risk for atelectasis and pneumonia.
The nurse is caring for a patient who has had a subarachnoid hemorrhage and is being cared for in the intensive care unit. Which of the following information about vasospasms should the nurse be aware of when planning care?
- A. The patient's blood pressure is 100/50 mm Hg.
- B. Endothelin will subside the vasospasm.
- C. The cerebrospinal fluid (CSF) report shows red blood cells (RBCs).
- D. Peak time for occurrence is 7-10 days post bleed.
Correct Answer: D
Rationale: Peak time for vasospasm to occur is 6-20 days after the initial bleed. In addition, release of endothelin (a potent vasoconstrictor) may play a major role in the induction of cerebral vasospasm after SAH rather than helping to relieve it. The BP is within normal limits. RBCs in the CSF are a typical clinical manifestation of a subarachnoid hemorrhage.
The nurse is caring for a patient who has had a stroke and has a new prescription to attempt oral feedings. After assessing the patient's gag reflex, which of the following actions should the nurse do next?
- A. Order a varied puréed diet.
- B. Assess the patient's appetite.
- C. Assist the patient into a chair.
- D. Offer the patient a sip of juice.
Correct Answer: C
Rationale: The patient should be as upright as possible before attempting feeding to make swallowing easier and decrease aspiration risk. To assess swallowing ability, the nurse should initially offer water or ice to the patient. Puréed diets are not recommended because the texture is too smooth. The patient may have a poor appetite, but the oral feeding should be attempted regardless.
