A nurse is preparing to lift a heavy object.
Which of the following actions by the nurse indicates an understanding of body mechanics?

Choice A rationale:

Abstract thinking develops during Piaget's formal operational stage, not the preoperational stage. The preoperational stage is characterized by symbolic thinking and egocentrism but lacks the ability for abstract thought.

Choice B rationale:

Concrete operational thinking is focused on logical and systematic thinking related to concrete objects and events, and it does not involve abstract thinking. Abstract thinking, including hypothetical and deductive reasoning, is a feature of the formal operational stage.

Choice C rationale:

Abstract thinking and formal operational thought develop during Piaget's formal operational stage, which typically begins in adolescence and continues into adulthood. This stage is characterized by the ability to think logically, solve complex problems, and consider abstract concepts.

Choice D rationale:

The sensorimotor stage is the earliest stage in Piaget's theory of cognitive development, and it is primarily concerned with sensory and motor exploration. Abstract thinking is not a component of this stage. .

Choice A rationale:

Fibromyalgia. Fibromyalgia is a chronic condition characterized by widespread musculoskeletal pain, fatigue, and tender points. It is not an example of acute pain. Acute pain typically has a sudden onset and is of limited duration.

Choice B rationale:

Peripheral neuropathy. Peripheral neuropathy can cause both acute and chronic pain, depending on the underlying cause. However, it is not a classic example of acute pain. Acute pain is usually associated with a specific injury or condition and has a sudden onset.

Choice C rationale:

Rheumatoid arthritis. Rheumatoid arthritis is a chronic autoimmune condition that can cause joint pain and inflammation. While it can have acute flares of pain, it is primarily considered a chronic condition. Acute pain typically results from injuries or conditions with a sudden onset.

Choice D rationale:

Surgical incision. This is the correct answer. A surgical incision represents a classic example of acute pain. It is a pain that results from a specific event, in this case, surgery, and typically has a well-defined onset and duration. Acute pain is often sharp and intense, and it resolves as the incision heals.
