Which statement is true regarding a transient ischemic attack (TI
This is potentially a warning sign of a hemorrhagic stroke.
This is potentially a warning sign of an ischemic stroke.
Neurological deficits last for 72 hours or less.
The client will have a small area of brain infarction.
The Correct Answer is B
Choice A reason:
A transient ischemic attack (TIA) is more commonly a warning sign of an ischemic stroke, not a hemorrhagic stroke. TIAs are caused by temporary blockages that do not result in permanent damage, unlike hemorrhagic strokes that involve bleeding in the brain.
Choice B reason:
A TIA is indeed a warning sign of a potential ischemic stroke. It is caused by a temporary disruption of blood flow to the brain and can serve as an early indicator of a future ischemic stroke if risk factors are not managed.
Choice C reason:
While the symptoms of a TIA can resolve within 24 hours, stating that neurological deficits last for 72 hours or less is inaccurate. The defining feature of a TIA is that symptoms resolve within a short period, typically within a few minutes to hours, but not extending up to 72 hours.
Choice D reason:
A TIA does not cause a small area of brain infarction. By definition, a TIA results in no permanent brain damage or infarction, which distinguishes it from a stroke where an infarction does occur.

Correct Answer is C
Explanation
Choice A reason: A hemorrhagic stroke occurs due to bleeding in the brain, often from a burst blood vessel. While individuals with cardiovascular disease might have risk factors, atrial fibrillation primarily increases the risk for strokes caused by clots, not bleeding.
Choice B reason: A thrombotic stroke is caused by a clot that forms within the blood vessels of the brain. While cardiovascular disease can contribute to thrombosis, atrial fibrillation more commonly leads to embolic strokes due to clots forming in the heart and traveling to the brain.
Choice C reason: This is the correct answer. Atrial fibrillation increases the risk of embolic strokes because it can cause blood clots to form in the heart. These clots can travel to the brain and cause an embolic stroke, which is why patients with atrial fibrillation are often on anticoagulant therapy.
Choice D reason: A subarachnoid stroke involves bleeding in the space between the brain and the surrounding membrane. It is typically associated with aneurysms or head injury, rather than atrial fibrillation. This choice does not align with the client’s condition.
Correct Answer is B
Explanation
Choice A reason:
Chewing sublingual medication is inappropriate as it is designed to dissolve under the tongue for rapid absorption into the bloodstream. Chewing it would alter the intended administration route and reduce its effectiveness.
Choice B reason:
Allowing the medication to dissolve completely under the tongue is correct and ensures that it is absorbed quickly into the bloodstream. This method allows the active ingredient to bypass the digestive system and liver, providing faster therapeutic effects.
Choice C reason:
While it is essential to follow any specific dietary instructions for medications, drinking juice or water typically does not interfere with sublingual medications. This statement does not accurately reflect the correct administration technique.
Choice D reason:
Placing sublingual medication between the cheek and gum is incorrect as this method is intended for buccal medications, not sublingual ones. Sublingual medications should be placed under the tongue to dissolve properly.
