A client has been found unresponsive at home for an undetermined period of time. A cerebrovascular accident (CVA) is suspected, and the family is demanding a clot buster be used to restore functioning. The nurse knows that successful use of tissue plasminogen activator (TPA) in a client with CVA requires which factor(s) to be true? Select all that apply.
- A. Symptoms no longer evolving
- B. Presence of an ischemic stroke
- C. Used concurrently with heparin therapy
- D. Administered intramuscularly for faster response
- E. Administered within 3 hours of onset of symptoms
- F. Administered for hemorrhagic strokes
Correct Answer: B,E
Rationale: TPA is a thrombolytic agent that can limit neurologic${{content}} neurologic deficits if given IV within 3 hours of onset of an ischemic CVA. Waiting for symptoms to stabilize (no longer evolving) may take days and would not be appropriate for the use of TPA. TPA is not used in conjunction with other anticoagulants and would never be used to treat a hemorrhagic stroke (promotes more bleeding).

A client has tension headaches. The nurse recommends massage as a treatment for tension headaches. How does massage help clients with tension headaches?
- A. Reduces hypotension
- B. Increases appetite
- C. Relaxes muscles
- D. Relieves migraines
Correct Answer: C
Rationale: Massaging relaxes tense muscles, causes local dilation of blood vessels, and relieves headache. However, this approach is not likely to help a client with migraine or cluster headaches. Massage is not offered to clients with tension headaches to increase their appetite or reduce hypotension.
A client has just been diagnosed with a cerebral aneurysm. In planning discharge teaching for this client, what instructions should be delivered by the nurse to the client?
- A. Avoid heavy lifting.
- B. Avoid fiber in the diet.
- C. Take an antacid frequently.
- D. Take an herbal form of feverfew.
Correct Answer: A
Rationale: A client with an aneurysm should be advised to avoid heavy lifting, extreme emotional situations, or straining of stools because these activities increase intracranial pressure and thereby headaches and potential rupture of aneurysm. Avoidance of fiber may lead to constipation and straining with stools and would not be recommended. There would not be a recommendation for antacids or feverfew in the discharge teaching.
While making initial rounds after coming on shift, the nurse finds a client thrashing about in bed complaining of a severe headache. The client tells the nurse the pain is behind the right eye, which is red and tearing. What type of headache would the nurse suspect this client of having?
- A. Migraine
- B. Tension
- C. Cluster
- D. Sinus
Correct Answer: C
Rationale: A person with a cluster headache has pain on one side of the head, usually behind the eye, accompanied by nasal congestion, rhinorrhea (watery discharge from the nose), and tearing and redness of the eye. The pain is so severe that the person is not likely to lie still; instead, the person may pace or thrash about. The symptoms in the scenario do not describe the other types of headaches listed.
A client is brought into the emergency department with a diagnosis of ruptured cerebral aneurysm. Which assessment data provides the most important information in preparing for the nursing care of this client?
- A. Blood pressure 180/98 mm Hg
- B. Alert and oriented times three
- C. Grade V on the Hunt-Hess Scale
- D. Complaint of severe splitting headache
Correct Answer: C
Rationale: The Hunt-Hess Scale is used for grading a client with a cerebral aneurysm and provides the most accurate assessment as listed. An elevated blood pressure is anticipated with a cerebral aneurysm. Being alert and oriented provides little assessment value without additional neurologic data. Complaint of severe headache is subjective and not as significant as results from using the Hunt-Hess Scale.
A client with a history of atrial fibrillation has experienced a TIA. What does the nurse expect will be the priority preventative medical treatment(s) to reduce the risk of a cerebrovascular accident (CVA)? Select all that apply.
- A. Cholesterol-lowering drugs
- B. Anticoagulant therapy
- C. Monthly prothrombin levels
- D. Carotid endarterectomy
- E. Percutaneous transluminal angioplasty
Correct Answer: A,B
Rationale: To manage atherosclerosis and the consequences of cardiac arrhythmias, especially atrial fibrillation, cholesterol-lowering drugs and prophylactic anticoagulant or antiplatelet therapy are prescribed. Prothrombin and international normalized ratio (INR) levels may be prescribed to monitor therapeutic effects of anticoagulant therapy. Carotid endarterectomy would be anticipated only when the carotids have narrowing from plaque. Similarly, a percutaneous transluminal angioplasty (also called a balloon angioplasty) accompanied by placement of a stent is performed to dilate the carotid artery and increase blood flow to the brain.
