Final answer:
The OT should follow the practice of keeping instructions simple and clear when administering standardized tests to a 4-year-old preschool child.
Step-by-step explanation:
When administering standardized tests to a 4-year-old preschool child, the occupational therapist (OT) should follow the practice of keeping instructions simple and clear. This is because young children may have limited attention spans and understanding complex instructions might confuse them. It is important for the OT to communicate in a way that the child can easily comprehend.
Using adult-sized equipment (A) may not be appropriate as it could be difficult for a 4-year-old to handle or may not accurately assess their abilities. Offering rewards for correct answers (B) is not recommended as it can introduce bias and may not accurately measure the child's skills. Allowing breaks during the test (D) may be necessary to accommodate the child's attention span and reduce fatigue.
