A nurse is preparing to lift a heavy object.
Which of the following actions by the nurse indicates an understanding of body mechanics?
They keep their feet together when lifting an object.
They bend at the hip when lifting.
They twist their spine when lifting.
They stand close to the object being moved.
The Correct Answer is D
Choice A rationale:
Keeping the feet together when lifting an object is not a proper body mechanics technique. It can lead to instability and an increased risk of injury because the base of support is not wide enough. Therefore, this choice does not indicate an understanding of body mechanics.
Choice B rationale:
Bending at the hip when lifting is also an incorrect body mechanics technique. Proper body mechanics involve bending at the knees and keeping the back straight to reduce the risk of back injuries. Bending at the hips can strain the lower back, making it an incorrect choice.
Choice C rationale:
Twisting the spine when lifting is a harmful practice in body mechanics. Twisting the spine can lead to spinal injuries, especially when lifting heavy objects. Proper body mechanics emphasize keeping the spine aligned and not twisting during lifting. Therefore, this choice does not indicate an understanding of body mechanics.
Choice D rationale:
Standing close to the object being moved is the correct body mechanics technique. This choice demonstrates an understanding of proper body mechanics because it reduces the strain on the back and minimizes the effort required to lift a heavy object. Keeping a wide base of support and using the leg muscles rather than the back muscles are essential principles of proper body mechanics. This is the correct choice. .

Correct Answer is A
Explanation
Choice A rationale:
"Keep your back straight.”. Maintaining correct posture when transferring clients is essential to prevent injuries to both the nurse and the patient. The correct answer, "Keep your back straight," is crucial in ensuring that the nurse avoids straining their back muscles. When transferring patients, it's essential to use proper body mechanics and keep the spine in a neutral position. This minimizes the risk of back injuries and promotes safe patient handling. Bending or twisting the back can lead to musculoskeletal problems, such as back pain or herniated discs.
Choice B rationale:
"Keep your knees straight.”. Keeping your knees straight is not the correct choice for maintaining correct posture when transferring clients. In fact, it's essential to keep your knees slightly bent when lifting or transferring a patient. This position helps to maintain stability and distribute the weight evenly, reducing the risk of injury.
Choice C rationale:
"Tilt your head toward your chest.”. Tilting the head toward the chest is unrelated to maintaining proper posture during patient transfers. It is important to keep the head in a neutral position while transferring patients, focusing on the back and leg positioning.
Choice D rationale:
"Loosen your abdominal muscles.”. Loosening abdominal muscles is not a recommended practice during patient transfers. Maintaining core strength and stability is essential for proper body mechanics. Relaxing the abdominal muscles can lead to poor posture and decreased stability, increasing the risk of injury.
Correct Answer is C
Explanation
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. .
