2024 PN NCLEX Questions Nursing Practice Question
A preschooler has successfully completed the test item 'counts 5 blocks' on the Denver II test. This pass is evidence of which of the following developmental concepts?
Correct Answer: D
Rationale: Successfully counting five blocks demonstrates the concept of conservation, which refers to a child's understanding that quantity remains the same despite changes in shape or arrangement. This ability indicates cognitive development in recognizing that the number of blocks does not change, even when they are counted in a different order or configuration.
Option A, centration, involves focusing on one aspect of a situation while ignoring others, which does not apply here. Option B, causality, relates to understanding cause-and-effect relationships, not counting. Option C, nonreversibility, refers to the inability to mentally reverse a process, which is not directly linked to counting skills.
