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 B
Explanation
Choice A reason:
Pulling the auricle upward and outward is appropriate for older children and adults but not for a 2-year-old. In young children, the ear canal is oriented differently, so this method would not effectively straighten the canal for proper eardrop administration.
Choice B reason:
Pulling the auricle down and back is the correct technique for children under three years old. This action helps straighten the ear canal, ensuring the eardrops are correctly administered into the canal and reach the affected area effectively.
Choice C reason:
Sitting the child up to insert a cotton ball into the innermost ear canal is not standard practice. Cotton balls are typically placed at the outer part of the ear canal to absorb excess drops, but it is not necessary to sit the child up specifically for this purpose.
Choice D reason:
Sitting the child up for 2 to 3 minutes after instilling drops can help the medication settle in the ear, but this is not the primary action required to straighten the ear canal for administering the drops. It can be a follow-up step but not the main technique for initial administration.
Correct Answer is B
Explanation
Choice A reason:
Vitamin D is important for bone health and the absorption of calcium but does not play a direct role in the wound healing process. Its primary function is to maintain proper bone structure and immune function, which, while beneficial, is not specifically focused on wound healing.
Choice B reason:
Protein is crucial for wound healing as it provides the necessary building blocks for tissue repair and regeneration. Proteins are essential for the production of collagen and other components of skin and tissue, making them a vital nutrient in the healing process. Ensuring adequate protein intake helps accelerate recovery and strengthen new tissue.
Choice C reason:
Vitamin B, particularly B12 and folic acid, supports overall health and can aid in red blood cell production and energy metabolism. However, it is not the primary nutrient required for wound healing. Its role is more supplementary compared to the direct impact of protein on tissue repair.
Choice D reason:
Calcium is essential for bone health and muscular function but does not have a direct role in the process of wound healing. While important for overall health, calcium is not as critical for wound repair as protein.
