Question 1
Regular
A patient has had an ischemic stroke and has been admitted to the medical unit. What action should the nurse perform to best prevent joint deformities?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Place a pillow in the axilla when there is limited external rotation. This action helps maintain proper joint alignment and prevents contractures, which are crucial in managing patients post-ischemic stroke to avoid joint deformities.
A: Place the patient in the prone position for 30 minutes/day. This position can actually increase the risk of pressure ulcers and does not effectively prevent joint deformities in stroke patients.
B: Assist the patient in acutely flexing the thigh to promote movement. Acute flexion may lead to muscle shortening and contractures, counteracting the goal of preventing joint deformities after a stroke.
D: Place the patient's hand in pronation. Pronating the hand can contribute to deformities and does not support optimal positioning or mobility following an ischemic stroke.

Question 2
Regular
A patient diagnosed with transient ischemic attacks (TIAs) is scheduled for a carotid endarterectomy. The nurse explains that this procedure will be done for what purpose?
Correct!
Incorrect
The correct answer is: C
Rationale
To remove atherosclerotic plaques blocking cerebral flow. This procedure aims to restore adequate blood flow to the brain by eliminating plaque buildup in the carotid arteries, which can lead to TIAs.
A: To decrease cerebral edema. This procedure does not primarily target cerebral edema, which relates to fluid accumulation in brain tissue rather than addressing vascular obstructions.
B: To prevent seizure activity that is common following a TIA. Seizure activity is not a typical complication of TIAs, and carotid endarterectomy focuses on improving cerebral blood flow, not preventing seizures.
D: To determine the cause of the TIA. The procedure is not diagnostic; rather, it is therapeutic, aimed at treating the underlying obstruction rather than identifying the cause of TIAs.

Question 3
Regular
The nurse is discharging home a patient who suffered a stroke. He has a flaccid right arm and leg and is experiencing problems with urinary incontinence. The nurse makes a referral to a home health nurse because of an awareness of what common patient response to a change in body image?
Correct!
Incorrect
The correct answer is: C
Rationale
The patient is experiencing depression.
Depression is a common response to changes in body image following a stroke, especially with the loss of function in the right arm and leg, as well as urinary incontinence. These changes can lead to feelings of grief, loss, and hopelessness, prompting the nurse to refer the patient for additional support through a home health nurse.
A: Denial This response typically involves refusing to accept the reality of the situation, which does not align with the patient's visible physical challenges and emotional state.
B: Fear While fear can occur, it often relates to anxiety about the future rather than the emotional impact of altered body image, which is more closely tied to depression.
D: Disassociation This response generally involves a disconnect from reality or emotions, which doesn't directly address the profound feelings associated with changes in body image after a stroke.

Question 4
Regular
When caring for a patient who had a hemorrhagic stroke, close monitoring of vital signs and neurologic changes is imperative. What is the earliest sign of deterioration in a patient with a hemorrhagic stroke of which the nurse should be aware?
Correct!
Incorrect
The correct answer is: B
Rationale
Alteration in level of consciousness (LOC) is the earliest sign of deterioration in a patient with a hemorrhagic stroke that nurses should monitor closely.
This option is correct as changes in LOC indicate potential increases in intracranial pressure and worsening neurological status, which are critical in assessing the patient's condition following a hemorrhagic stroke. Early detection can prompt timely interventions.
A: Generalized pain does not specifically indicate early deterioration in neurological status and may not be directly linked to changes in a patient's condition following a hemorrhagic stroke.
C: Tonicclonic seizures typically occur later in the course or as a result of significant brain injury rather than being an early sign of deterioration in hemorrhagic stroke patients.
D: Shortness of breath can arise from various conditions unrelated to stroke deterioration and does not serve as a reliable early indicator of neurological decline in these patients.

Question 5
Regular
The nurse is performing stroke risk screenings at a hospital open house. The nurse has identified four patients who might be at risk for a stroke. Which patient is likely at the highest risk for a hemorrhagic stroke?
Correct!
Incorrect
The correct answer is: B
Rationale
B: White male, age 60, with history of uncontrolled hypertension. Uncontrolled hypertension significantly elevates the risk of hemorrhagic strokes, as it can lead to weakened blood vessels and potential rupture in the brain.
A: White female, age 60, with history of excessive alcohol intake. While excessive alcohol intake poses risks for various health issues, it does not directly correlate with a higher likelihood of hemorrhagic strokes compared to hypertension.
C: Black male, age 60, with history of diabetes. Diabetes increases stroke risk overall, but it is more associated with ischemic strokes rather than hemorrhagic strokes, making it a lesser concern in this context.
D: Black male, age 50, with history of smoking. Smoking contributes to numerous health problems, yet it primarily raises the risk for ischemic strokes rather than hemorrhagic strokes, making it a less critical factor here.

Question 6
Regular
A patient who just suffered a suspected ischemic stroke is brought to the ED by ambulance. On what should the nurses primary assessment focus?
Correct!
Incorrect
The correct answer is: A
Rationale
Primary assessment should focus on cardiac and respiratory status. Ensuring stable heart function and adequate breathing is critical immediately after a suspected ischemic stroke, as these factors can significantly impact patient outcomes and guide further treatment decisions.
B: Seizure activity Monitoring for seizures is important, but it is secondary to assessing vital functions. Immediate threats to life, such as compromised cardiac or respiratory status, take precedence.
C: Pain While managing pain is essential, it does not address the acute medical priorities following a suspected stroke. Assessing vital signs holds greater urgency in this context.
D: Fluid and electrolyte balance Although important, this assessment is not as critical immediately after a suspected ischemic stroke. Prioritizing vital signs ensures immediate stabilization of the patient’s condition.

Question 7
Regular
A patient with a cerebral aneurysm exhibits signs and symptoms of an increase in intracranial pressure (ICP). What nursing intervention would be most appropriate for this patient?
Correct!
Incorrect
The correct answer is: D
Rationale
D: Absolute bed rest in a quiet, nonstimulating environment is the most appropriate intervention as it minimizes stimuli, reduces the risk of further increasing intracranial pressure, and promotes cerebral perfusion stability.
A: Range-of-motion exercises to prevent contractures could inadvertently elevate intracranial pressure, posing a risk to the patient’s condition, as physical activity may provoke symptoms or discomfort.
B: Encouraging independence with ADLs to promote recovery might lead to unnecessary stress and stimuli for the patient, which could exacerbate symptoms related to increased intracranial pressure.
C: Early initiation of physical therapy could introduce physical strain and stimulation, potentially worsening the patient's status and increasing the risk of complications associated with the cerebral aneurysm.

Question 8
Regular
A patient recovering from a stroke has severe shoulder pain from subluxation of the shoulder and is being cared for on the unit. To prevent further injury and pain, the nurse caring for this patient is aware of what principle of care?
Correct!
Incorrect
The correct answer is: D
Rationale
The patient should be taught to interlace fingers, place palms together, and slowly bring scapulae forward to avoid excessive force to shoulder. This technique promotes proper alignment and reduces the risk of further subluxation while facilitating gentle movement.
A: The patient should be fitted with a cast because use of a sling should be avoided due to adduction of the affected shoulder. A cast is inappropriate for shoulder subluxation management, as it restricts necessary movement and does not address pain or alignment.
B: Elevation of the arm and hand can lead to further complications associated with edema. Elevating the arm may not be inherently problematic and can actually help reduce swelling if done correctly.
C: Passively exercising the affected extremity is avoided to minimize pain. While minimizing pain is crucial, passive exercise can be beneficial for maintaining range of motion and preventing stiffness in the shoulder.

Question 9
Regular
The patient has been diagnosed with aphasia after suffering a stroke. What can the nurse do to best make the patients atmosphere more conducive to communication?
Correct!
Incorrect
The correct answer is: A
Rationale
Providing a board of commonly used needs and phrases enhances communication for a patient with aphasia by offering visual cues, reducing frustration, and enabling more effective interactions with caregivers and family members.
B: Having the patient speak to loved ones on the phone daily may not address the immediate communication barriers posed by aphasia, potentially increasing anxiety and frustration.
C: Helping the patient complete his or her sentences might inadvertently undermine their independence and confidence, as it does not encourage them to express their own thoughts fully.
D: Speaking in a loud and deliberate voice can be perceived as patronizing and may not aid comprehension, as aphasia primarily affects language processing rather than hearing ability.

Question 11
Regular
The nurse is caring for a patient diagnosed with an ischemic stroke and knows that effective positioning of the patient is important. Which of the following should be integrated into the patients plan of care?
Correct!
Incorrect
The correct answer is: C
Rationale
The patient should be placed in a prone position for 15 to 30 minutes several times a day. This positioning can enhance lung function, prevent pressure sores, and improve oxygenation, which is crucial for recovery after an ischemic stroke. It facilitates better respiratory mechanics and can aid in promoting overall patient comfort and rehabilitation.
A: The patients hip joint should be maintained in a flexed position. Maintaining a flexed hip can lead to joint contractures and discomfort, negatively impacting mobility and recovery in stroke patients.
B: The patient should be in a supine position unless ambulating. Remaining supine for prolonged periods increases the risk of pressure ulcers and does not optimize functional recovery following an ischemic stroke.
D: The patient should be placed in a Trendelenberg position two to three times daily to promote cerebral perfusion. This position can elevate intracranial pressure and is not typically recommended for stroke patients, as it may compromise their overall stability.

Question 12
Regular
A patient has been admitted to the ICU after being recently diagnosed with an aneurysm and the patients admission orders include specific aneurysm precautions. What nursing action will the nurse incorporate into the patients plan of care?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Maintain the patient on complete bed rest.
Complete bed rest is crucial for patients with an aneurysm to prevent any sudden movements or increases in intracranial pressure, which could lead to complications or rupture of the aneurysm.
A: Elevate the head of the bed to 45 degrees.
While positioning can be important, elevating the head of the bed may increase intracranial pressure and is not aligned with aneurysm precautions requiring strict bed rest.
C: Administer enemas when the patient is constipated.
Administering enemas can cause straining and increased pressure, which poses a risk for a patient with an aneurysm and contradicts the need for limited physical exertion.
D: Avoid use of thigh-high elastic compression stockings.
Compression stockings are often safe and beneficial for preventing deep vein thrombosis in immobilized patients, not a standard precaution specifically relating to aneurysm management.

Question 13
Regular
A nurse is caring for a patient diagnosed with a hemorrhagic stroke. When creating this patients plan of care, what goal should be prioritized?
Correct!
Incorrect
The correct answer is: B
Rationale
Maintain and improve cerebral tissue perfusion.
This goal is critical for a patient with a hemorrhagic stroke, as optimal cerebral perfusion is essential for minimizing further brain damage and promoting recovery. Prioritizing this objective directly addresses the underlying issue of blood flow disruption, which is central to the patient's condition.
A: Prevent complications of immobility. While important, preventing complications of immobility becomes secondary to addressing cerebral perfusion, which is vital for the patient's immediate recovery and overall prognosis.
C: Relieve anxiety and pain. Although alleviating emotional distress and discomfort is beneficial, it does not address the primary medical concern of restoring adequate blood flow to the brain.
D: Relieve sensory deprivation. This focus does not directly impact the acute medical needs of a hemorrhagic stroke, where ensuring adequate blood supply to the brain is paramount for patient survival and recovery.

Question 14
Regular
The nurse is preparing health education for a patient who is being discharged after hospitalization for a hemorrhagic stroke. What content should the nurse include in this education?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Take antihypertensive medication as ordered. Managing blood pressure is crucial for stroke recovery, as it helps reduce the risk of further strokes and supports overall brain health post-hospitalization.
A: Mild, intermittent seizures can be expected. While seizures can occur after a stroke, they are not a standard expectation for all patients, making this information misleading in the discharge education.
B: Take ibuprofen for complaints of a serious headache. Ibuprofen may not be appropriate for post-stroke headaches, as it can increase bleeding risk, thus conflicting with safe recovery protocols.
D: Drowsiness is normal for the first week after discharge. Although some fatigue can occur, excessive drowsiness could indicate complications and should not be normalized without further assessment and guidance.

Question 16
Regular
A patient is brought by ambulance to the ED after suffering what the family thinks is a stroke. The nurse caring for this patient is aware that an absolute contraindication for thrombolytic therapy is what?
Correct!
Incorrect
The correct answer is: A
Rationale
Evidence of hemorrhagic stroke. This condition presents a significant risk for patients receiving thrombolytic therapy, as it can exacerbate bleeding, leading to further neurological damage and increased mortality.
B: Blood pressure of 180/110 mm Hg. While elevated blood pressure can pose risks, it is often manageable and does not automatically exclude a patient from receiving thrombolytic treatment.
C: Evidence of stroke evolution. Ongoing stroke symptoms may prompt further assessment but do not constitute a definitive contraindication for thrombolytic therapy, as treatment may still be beneficial.
D: Previous thrombolytic therapy within the past 12 months. Although prior treatment presents considerations, it does not serve as an absolute contraindication, depending on the patient's current clinical scenario and risk factors.

Question 17
Regular
When caring for a patient who has had a stroke, a priority is reduction of ICP. What patient position is most consistent with this goal?
Correct!
Incorrect
The correct answer is: B
Rationale
Elevation of the head of the bed. Elevating the head reduces intracranial pressure (ICP) by promoting venous drainage from the brain, thereby improving cerebral circulation and preventing further complications following a stroke.
A: Head turned slightly to the right side. This position does not significantly impact ICP reduction and may even hinder optimal venous drainage, contributing to increased pressure in the cranial cavity.
C: Position changes every 15 minutes while awake. Frequent positional changes do not specifically address ICP reduction and may lead to instability, ultimately undermining the goal of maintaining a safe and effective position for the patient.
D: Extension of the neck. Neck extension can obstruct venous return from the brain, potentially exacerbating ICP and increasing the risk of complications, which undermines the primary focus of proper stroke care.

Question 18
Regular
A patient who suffered an ischemic stroke now has disturbed sensory perception. What principle should guide the nurses care of this patient?
Correct!
Incorrect
The correct answer is: A
Rationale
The patient should be approached on the side where visual perception is intact. This approach fosters sensory recognition and spatial awareness, aiding rehabilitation by reinforcing the patient's awareness of their surroundings and enhancing interaction with caregivers.
B: Attention to the affected side should be minimized to decrease anxiety. Reducing focus on the affected side may hinder the patient's awareness and recovery, preventing necessary engagement and adaptation.
C: The patient should avoid turning in the direction of the defective visual field to minimize shoulder subluxation. While minimizing shoulder subluxation is important, avoiding movement toward the defective visual field does not directly address sensory perception issues.
D: The patient should be approached on the opposite side of where the visual perception is intact to promote recovery. This method could confuse the patient and impede recovery by neglecting the sensory feedback from the intact visual side.

What should be included in the patients care plan when establishing an exercise program for a patient affected by a stroke?
Correct!
Incorrect
The correct answer is: D
Rationale
D: Exercise the affected extremities passively four or five times a day. This approach ensures that the patient maintains flexibility and mobility in their affected limbs, which is crucial for recovery after a stroke.
A: Schedule passive range of motion every other day. Infrequent sessions may not sufficiently promote muscle function or prevent stiffness, hindering the rehabilitation process for stroke patients.
B: Keep activity limited, as the patient may be over stimulated. While caution is necessary, restricting movement too much can lead to decreased mobility and hinder recovery, which is counterproductive.
C: Have the patient perform active range-of-motion (ROM) exercises once a day. A daily frequency may not provide enough stimulation for progress, especially in patients needing more frequent passive engagement to regain function.

Question 29
Regular
A nurse in the ICU is providing care for a patient who has been admitted with a hemorrhagic stroke. The nurse is performing frequent neurologic assessments and observes that the patient is becoming progressively more drowsy over the course of the day. What is the nurses best response to this assessment finding?
Correct!
Incorrect
The correct answer is: D
Rationale
The patient's increasing drowsiness is a significant concern and should be communicated to the physician as it may indicate clinical deterioration, which requires immediate evaluation and intervention to prevent further complications.
A: Report this finding to the physician as an indication of decreased metabolism. Decreased metabolism isn't the primary concern in this scenario; the focus should be on potential neurological decline indicating a need for urgent assessment.
B: Provide more stimulation to the patient and monitor the patient closely. Increased stimulation may not be appropriate for a patient showing signs of drowsiness, as it could exacerbate their condition or lead to further complications.
C: Recognize this as the expected clinical course of a hemorrhagic stroke. While some changes can occur, progressive drowsiness typically signals deterioration rather than a normal expectation, necessitating prompt medical attention.

Question 31
Regular
A preceptor is discussing stroke with a new nurse on the unit. The preceptor would tell the new nurse which cardiac dysrhythmia is associated with cardiogenic embolic strokes?
Correct!
Incorrect
The correct answer is: B
Rationale
Atrial fibrillation is the cardiac dysrhythmia associated with cardiogenic embolic strokes. This condition leads to irregular blood flow, fostering clot formation in the heart, which can subsequently travel to the brain, resulting in a stroke.
A: Ventricular tachycardia does not typically result in embolic strokes as it primarily affects the heart's pumping efficacy rather than promoting clot formation.
C: Supraventricular tachycardia generally causes rapid heart rates but lacks the turbulent blood flow necessary for clots, making it less relevant to embolic stroke risk.
D: Bundle branch block pertains to electrical conduction issues in the heart and does not create the conditions for clot formation, thus not contributing to embolic strokes.

Question 32
Regular
The pathophysiology of an ischemic stroke involves the ischemic cascade, which includes the following steps: 1. Change in pH 2. Blood flow decreases 3. A switch to anaerobic respiration 4. Membrane pumps fail 5. Cells cease to function 6. Lactic acid is generated. Put these steps in order in which they occur.
Correct!
Incorrect
The correct answer is: C
Rationale
The sequence of ischemic stroke events is 236145.
The correct order begins with decreased blood flow, leading to pH changes, a switch to anaerobic respiration, failure of membrane pumps, cellular dysfunction, and finally, lactic acid accumulation. This sequence highlights the progressive nature of the ischemic cascade in stroke pathology.
A: 635241 Cells generating lactic acid occur later in the cascade, not initially. Membrane pump failure follows anaerobic respiration, making this sequence misaligned with the actual physiological processes.
B: 352416 The switch to anaerobic respiration comes after blood flow decreases. This option misplaces the order of events critical to understanding the ischemic cascade's progression.
D: 162534 The initial steps of pH change and decreased blood flow are incorrectly sequenced. This arrangement disrupts the logical flow of the ischemic cascade's physiological changes.
