A preceptor discussing stroke with a new nurse on the unit would tell the new nurse that which cardiac dysrhythmia is associated with cardiogenic embolic strokes?
Bundle branch block
Ventricular tachycardia
Supraventricular tachycardia
Atrial fibrillation
The Correct Answer is D
Reasoning:
Choice A reason: Bundle branch block affects ventricular conduction but does not typically cause emboli. It may lead to dyssynchrony but lacks the stasis in the atria that promotes clot formation, making it less associated with cardiogenic embolic strokes compared to atrial fibrillation’s thrombus-forming mechanism.
Choice B reason: Ventricular tachycardia is a life-threatening arrhythmia affecting the ventricles, causing hemodynamic instability but not typically embolic strokes. It does not promote atrial stasis or clot formation, which are necessary for cardiogenic emboli to travel to the brain, unlike atrial fibrillation.
Choice C reason: Supraventricular tachycardia causes rapid heart rates above the ventricles but is less likely to form atrial clots than atrial fibrillation. It does not typically cause the prolonged stasis needed for thrombus formation, making it less associated with embolic strokes in the brain.
Choice D reason: Atrial fibrillation is strongly associated with cardiogenic embolic strokes. It causes irregular atrial contractions, leading to blood stasis in the atria, promoting thrombus formation. These clots can embolize to the brain, causing ischemic stroke, making it a key risk factor requiring anticoagulation.

Correct Answer is C
Explanation
Reasoning:
Choice A reason: Arranging for friends and family to sit with the client may provide comfort but does not directly prevent injury from agitation. Family presence cannot ensure physical safety during sudden movements, whereas padding side rails directly reduces harm from agitation-related impacts in head injury.
Choice B reason: Restraining the client increases agitation and injury risk in head-injured patients, as it can exacerbate distress and cause pressure injuries. Non-restrictive measures like padding are safer, reducing harm from agitation without compromising autonomy or worsening neurological status in this high-risk population.
Choice C reason: Padding side rails is the best intervention to prevent injury in an agitated client with a head injury. Agitation increases the risk of hitting bed rails, causing bruises or fractures. Padding absorbs impact, ensuring safety without restricting movement, addressing the immediate physical risk effectively.
Choice D reason: Administering opioids PRN may reduce pain but not agitation in head injury. Opioids can depress respiration and consciousness, potentially masking neurological changes or worsening ICP, making them less safe than padding side rails to prevent physical injury from agitation-related movements.
Correct Answer is B
Explanation
Reasoning:
Choice A reason: Placing the clock on the affected side (left in right-sided stroke) worsens hemianopsia issues, as the client cannot see the left visual field. This increases neglect and disorientation. Positioning items in the intact visual field helps the client compensate for the visual deficit effectively.
Choice B reason: Placing extremities in the client’s intact visual field (right side in right-sided stroke) compensates for left hemianopsia. This helps the client maintain awareness of their body, reducing neglect and injury risk, as they cannot see the left side, improving safety and sensory integration.
Choice C reason: Approaching from the impaired side (left in right-sided stroke) increases disorientation and neglect in hemianopsia. Approaching from the intact right side ensures the client can see and respond, improving communication and reducing startle or confusion caused by unseen approaches.
Choice D reason: Keeping lighting low may reduce glare but does not address hemianopsia’s visual field loss. Adequate lighting in the intact field enhances visibility of objects and extremities, aiding compensation for the deficit. Low lighting could increase disorientation in clients with visual impairments.
