2.

A stroke is a sudden onset of a focal neurologic deficit.
- True
- False
Correct Answer

A. True

Explanation

Before we get started with questions regarding stroke, it helps to know what a stroke entails. Please note that cerebrovascular disease/accident refers to any type of vascular disease in the brain.

Rate this question:

2
3.

tPA (alteplase) is the preferred fibrinolytic for stroke treatment.
- True
- False
Correct Answer

A. True

Explanation

Alteplase is the preferred fibrinolytic agent for stroke treatment. Streptokinase actually increased morbidity and mortality.

Rate this question:

1
4.

Aspirin 325 mg is a viable option for secondary prophylaxis in stroke patients.
- True
- False
Correct Answer

A. True

Explanation

The higher dose of aspirin, 325 mg, is an option; give within 24-48 hours of the stroke. 81 mg is also acceptable.

Rate this question:

2
5.

Fibrinolytic therapy may be used for hemorrhagic strokes.
- True
- False
Correct Answer

A. False

Explanation

The patient has just suffered a massive bleeding episode in his or her cranium, so do not administer another agent that will seriously increase their bleeding. In such situations (hemorrhagic strokes), there are few therapeutic options but focus on controlling hypertension (note the special goals), reverse warfarin if the patient was taking, and use mannitol to maintain serum osmolality and arterial pressure.

Rate this question:

2
6.

A transient ischemic attack (TIA), also known as a mini-stroke, is of no concern, as it will recede in no more than 24 hours.
- True
- False
Correct Answer

A. False

Explanation

TIAs are neurological deficits in which blood flow to the brain decreases; they last from a few seconds to 24 hours. Symptoms may include transient motor and sensory loss in the face, arm, or hand; vertigo; and numbness. However, they should be taken seriously, as a stroke can occur soon after a TIA.

Rate this question:

2
7.

Besides the tests such as CT scans or MRI that are necessary for establishing the diagnosis of ischemic stroke, which is the one test that may preclude the initiation of IV tPA, if IV tPA is appropriate?
- Blood glucose
- CK-MB
- CRP
- Troponin
Correct Answer

A. Blood glucose

Explanation

Blood glucose is the only assessment that must precede the initiation of IV tPA.

Rate this question:

1
8.

Which of the following are signs of a stroke?
- Decreased urination
- Difficulty speaking
- Dizziness
- Pain that radiates from the chest to the left arm
- Sudden changes in vision
- Sudden numbness/weakness of face, arm, or leg, especially on one side of the body
- Sudden severe headache
Correct Answer(s)

A. Difficulty speaking
A. Dizziness
A. Sudden changes in vision
A. Sudden numbness/weakness of face, arm, or leg, especially on one side of the body
A. Sudden severe headache

Explanation

The symptoms selected (sudden numbness/weakness of the face, arm, or leg, especially on one side of the body; difficulty speaking; sudden changes in vision; and sudden severe headache) are signs of a stroke and should be presented to patients as situations that require emergency assistance. Decreased urination is not related to a stroke. Pain radiating from the chest to the left arm is a sign of myocardial infarction.

Rate this question:

1
9.

What is the blood pressure goal to establish a patient for fibrinolytic therapy?
- < 140/90 mmHg
- < 160/90 mmHg
- < 185/110 mmHg
- < 205/120 mmHg
Correct Answer

A. < 185/110 mmHg

Explanation

The blood pressure goal for a patient receiving fibrinolytic therapy is less than 185/110 mmHg. High blood pressure is keeping the blood supply to the brain, so antihypertensive medications should not be given unless the blood pressure is greater than 185/110 mmHg and fibrinolytic therapy is desired. For the 24 hours following tPA, the blood pressure should be maintained at less than 185/105 mmHg.

Rate this question:

2
10.

For patients who do not receive fibrinolytic therapy, utilize blood pressure medications to lower blood pressure by 15% during the first 24 hours of stroke onset only if the patient's blood pressure is above what threshold?
- >140/90 mmHg
- >160/90 mmHg
- >185/110 mmHg
- >220/120 mmHg
Correct Answer

A. >220/120 mmHg

Explanation

As mentioned in the previous question, high blood pressure during a stroke is key for preserving perfusion to the brain. Therefore, only utilize medications to lower blood pressure if the patient's blood pressure is greater than 220/120 mmHg.

Rate this question:

2
11.

How often should blood pressure and neurological assessment be obtained during alteplase therapy?
- Hours 1-2: Every 15 minutes
- Hours 1-2: Every 30 minutes
- Hours 1-2: Every 60 minutes
- Hours 2-8: Every 15 minutes
- Hours 2-8: Every 30 minutes
- Hours 2-8: Every 60 minutes
- Hours 8-24: Every 15 minutes
- Hours 8-24: Every 30 minutes
- Hours 8-24: Every 60 minutes
Correct Answer(s)

A. Hours 1-2: Every 15 minutes
A. Hours 2-8: Every 30 minutes
A. Hours 8-24: Every 60 minutes

Explanation

Please note the intense monitoring required during and after tPA therapy. Stroke patients are often admitted to an ICU or stroke unit. Of note, increase the frequency of monitoring if the patient has blood pressure greater than 180/105 mmHg and administer medications to keep the blood pressure below 180/105 mmHg.

12.

Check the potentially modifiable risk factors for having a stroke.
- Atrial fibrillation
- Diabetes
- Dyslipidemia
- Family history of cardiovascular disease
- Hypertension
- Smoking
Correct Answer(s)

A. Atrial fibrillation
A. Diabetes
A. Dyslipidemia
A. Hypertension
A. Smoking

Explanation

Atrial fibrillation can lead to clots, which can enter the cerebral vasculature and cause a stroke. Diabetes is yet another modifiable risk factor, but controlled diabetes will minimize the risk of a stroke. Dyslipidemia can lead to emboli that cause an ischemic stroke. Unfortunately, there is nothing possible to solve a family history, other than to be extra healthy with diet and exercise! Hypertension is a major factor in causing strokes, so keep the patient's blood pressure under control. Smoking cessation will also decrease the risk of cardiac morbidities such as a stroke.

13.

Patients must be treated with fibrinolytic therapy no more than 3 hours from the onset of symptoms.
- True
- False
Correct Answer

A. False

Explanation

This is false; in certain circumstances, the fibrinolytic may be used up to 4.5 hours after the onset of symptoms.

14.

Select the correct dosing for tPA (Alteplase) in acute ischemic stroke; check all that apply to the dosing.
- Infuse 0.9 mg/kg (max dose 100 mg) over 60 minutes
- Infuse 0.9 mg/kg (max dose 90 mg) over 60 minutes
- Administer 25% of the dose as a bolus over 1 minute
- Administer 10% of the dose as a bolus over 1 minute
Correct Answer(s)

A. Infuse 0.9 mg/kg (max dose 90 mg) over 60 minutes
A. Administer 10% of the dose as a bolus over 1 minute

Explanation

The dosing for Alteplase is 0.9 mg/kg (max dose 90 mg) over 60 minutes, with 10% of the dose given as a bolus over 1 minute. For a 100 kg patient, the dose would be 90 mg total, with 9 mg given as the bolus and 81 mg given over the rest of the hour. For a 70 kg patient, the dose would be 63 kg total, with 6.3 mg given as a bolus and 56.7 mg given over the rest of the hour.

15.

Which of the following medications are needed for secondary prophylaxis in stroke patients?
- Antihypertensives
- Aspirin
- Statin
- Warfarin
Correct Answer(s)

A. Antihypertensives
A. Aspirin
A. Statin
A. Warfarin

Explanation

Of note, ACE-I plus diuretic is the recommended choice for antihypertensive medication. The addition of a statin is without regard to prior use; the pleiotropic effects of statins will be of benefit in preventing further emboli.

16.

Which of the following are exclusion criteria for receiving fibrinolytic therapy?
- Active internal bleeding
- Blood glucose < 90 mg/dL
- Blood pressure >185/110 mmHg
- INR>1.7
- Stroke within 3 months
Correct Answer(s)

A. Active internal bleeding
A. Blood pressure >185/110 mmHg
A. INR>1.7
A. Stroke within 3 months

Explanation

Any indications of increased risk of bleeding preclude the use of a fibrinolytic, which can cause life-threatening bleeding. Blood glucose should be normoglycemic: above 50 mg/dL. Of note is if the patient had a stroke within the past 3 months, then the patient is precluded from receiving a fibrinolytic. Also, blood pressure must be lower than 185/110 mmHg.
