Cerebrovascular Accident Flashcards

Q
  1. A patient is admitted with uncontrolled atrial fibrillation. The patient’s medication history includes vitamin D supplements and calcium. What type of stroke is this patient at MOST risk for?

A. Ischemic thrombosis

B. Ischemic embolism

C. Hemorrhagic

D. Ischemic stenosis

A

The answer is B.

If a patient is in uncontrolled a-fib they are at risk for clot formation within the heart chambers. This clot can leave the heart and travel to the brain. Hence, an ischemic embolism type stroke can occur. An ischemic thrombosis type stroke is where a clot forms within the artery wall of the neck or brain.

Q
  1. Which patient below is at most risk for a hemorrhagic stroke?

A. A 65 year old male patient with carotid stenosis.

B. A 89 year old female with atherosclerosis.

C. A 88 year old male with uncontrolled hypertension and a history of brain aneurysm repair 2 years ago.

D. A 55 year old female with atrial flutter.

A

The answer is C.

A hemorrhagic stroke occurs when bleeding in the brain happens due to a break in a blood vessel. Risk factors for a hemorrhagic stroke is uncontrolled hypertension, history of brain aneurysm, old age (due to aging blood vessels.) All the other options are at risk for an ischemic type of stroke.

D. TIAs don’t require medical treatment.

A

The answers are B and D.

Q
  1. A patient who has hemianopia is at risk for injury. What can you educate the patient to perform regularly to prevent injury?

A. Wearing anti-embolism stockings daily

B. Consume soft foods and tuck in chin while swallowing

C. Scanning the room from side to side frequently

D. Muscle training

A

The answer is C.

Hemianopia is limited vision in half of the visual field. The patient needs to scan the room from side to side to prevent injury.

17
Q
  1. You receive a patient who is suspected of experiencing a stroke from EMS. You conduct a stroke assessment with the NIH Stroke Scale. The patient scores a 40. According to the scale, the result is:

A. No stroke symptoms

B. Severe stroke symptoms

C. Mild stroke symptoms

D. Moderate stroke symptoms

A

The answer is B.

Scores on the NIH stroke scale range from 0 to 42, with 0 (no stroke symptoms) and 21-42 (severe stroke symptoms).

18
Q
  1. In order for tissue plasminogen activator (tPA) to be most effective in the treatment of stroke, it must be administered?

A. 6 hours after the onset of stroke symptoms

B. 3 hours before the onset of stroke symptoms

C. 3 hours after the onset of stroke symptoms

D. 12 hours before the onset of stroke symptoms

A

The answer is C.

tPa dissolves the clot causing the blockage in stroke by activating the protein that causes fibrinolysis. It should be given within 3 hours after the onset of stroke symptoms. It can be given 3 to 4.5 hours after onset IF the patient meets strict criteria. It is used for acute ischemia stroke, NOT hemorrhagic!!

19
Q
  1. Which patients are NOT a candidate for tissue plasminogen activator (tPA) for the treatment of stroke?

A. A patient with a CT scan that is negative.

B. A patient whose blood pressure is 200/110.

C. A patient who is showing signs and symptoms of ischemic stroke.

D. A patient who received Heparin 24 hours ago.

A

The answers are B and D.

Patients who are experiencing signs and symptoms of a hemorrhagic stroke, who have a BP for >185/110, and has received heparin or any other anticoagulants etc. are NOT a candidate for tPA. tPA is only for an ischemic stroke.

20
Q
  1. You’re assisting a patient who has right side hemiparesis and dysphagia with eating. It is very important to:

A. Keep the head of bed less than 30′.

B. Check for pouching of food in the right cheek.

C. Prevent aspiration by thinning the liquids.

D. Have the patient extend the neck upward away from the chest while eating.

A

The answer is B.
Because the patient has weakness on the right side and dysphagia the nurse should regularly check for pouching of food in the right cheek. Pouching of food in the cheek can lead to aspiration or choking. The HOB should be >30′, liquids thickened per MD order, and the patient should tuck in the chin to the chest while swallowing.

21
Q
  1. A patient has experienced right side brain damage. You note the patient is experiencing neglect syndrome. What nursing intervention will you include in the patient’s plan of care?

A. Remind the patient to use and touch both sides of the body daily.

B. Offer the patient a soft mechanical diet with honey thick liquids.

C. Ask direct questions that require one word responses.

D. Offer the bedpan and bedside commode every 2 hours.

A

The answer is A.

It is important to watch for neglect syndrome. This tends to happen in right side brain damage. The patient ignores the left side of the body in this condition. The nurse needs to remind the patient to use and touch both sides of the body daily and that the patient must make a conscious effort to do so.

22
Q

What is a stroke?

A

It is a condition that develops when blood rich in oxygen canNOTreach brain cells (due to either a blockage or bleeding). This causes thebrain cells to die.

23
Q

Types of Strokes

A
  1. Ischemic stroke

2. Hemorrhagic stroke

24
Q

Ischemic Heart

A

Ischemic (most common): due to a blood clot within a blood vessel or stenosis of an artery that feeds the brain tissue. This limits the blood that can reach the brain cells. This type of stroke can happen due to:

Embolism: where a clot has left a part of the body (example the heart: this can happen due to a heart valve problem or atrial fibrillation). The clot develops in the heart and travels to the brain, which stops blood flow.

Thrombosis: Clot forms within the artery wall within the neck or brain. This is seen in patients with hyperlipidemia or atherosclerosis

25
Q

TIA (transient ischemic attack)

A

-TIA (transient ischemic attack) also called a mini-stroke. This is where signs and symptoms of a stroke occurs but last only a few minutes to hours and resolves. It is a warning signs an impending stroke may occur. If this occurs the patient needs to seek treatment.

26
Q

Hemorrhagic Stroke

A

Hemorrhagic: this occurs when there is bleeding in the brain due to a break in a blood vessel. Therefore, no blood will perfuse to the brain cells. In addition, this can lead to excessive swelling from the leakage of blood in the brain. Causes of this type of stroke includes: rupture of a brain aneurysm, uncontrolledhypertension, or aging blood vessels (older age).

27
Q

Risk Factors for stroke

A

“Strokes Happen”

Smoking

Thinners (blood)

Rhythm changes (a-fib/flutter)

Oral Contraceptive

Kin (family history)

Excessive weight

Senior citizens

Hypertension

Atherosclerosis

Physical inactivity

Previous TIA

Elevated blood sugar (diabetes mellitus)

aNeurysm (brain)

28
Q

Interventions for aphasia

A

Communication is key (just because the patient can’t communicate doesn’t mean they have a mental deficit). They just can’t get it out and it takes them time. The nurse’s role is to help bridge the gap and make it less frustrating for the patient.

Receptive Aphasia: unable to comprehend speech (Wernicke’s area)
-use short phrases

  • use gestures or point while giving a command
  • be patient and not expect a fast response
  • remove distractions

Expressive Aphasia: comprehends speech but can’t respond back with speech (Broca’s area)
-be patient and let them speak

  • be direct and simple when asking questions…..give options
  • communication via a dry erase board
29
Q

Watch for neglect syndrome:

A

(tends to happen in right side brain damage). The patient is at risk for injury because patient ignores the affected side.

Remind patient to use and touch both sides of body daily (must make a conscious effort to do so).
Educate the patient about the importance of turning head side-to-side to prevent injuring the affected side.

Hemianopsia interventions: turning head side-to-side to see all visual fields to prevent injury.
