A nurse is teaching a class about Piaget's stages of cognitive development. The nurse should instruct that object permanence develops during which of the following stages?
Concrete operational
Sensorimotor
Formal operational
Preoperational
The Correct Answer is B
A. Concrete operational: This stage (7 to 11 years) is characterized by logical thinking about concrete events.
B. Sensorimotor: This stage (birth to about 2 years) is when infants learn about the world through their senses and actions. Object permanence—the understanding that objects continue to exist even when they cannot be seen, heard, or touched—develops in this stage.
C. Formal operational: This stage (12 years and up) involves abstract and moral reasoning.
D. Preoperational: This stage (2 to 7 years) is when children begin to engage in symbolic play and learn to manipulate symbols, but they don’t yet understand concrete logic.

Correct Answer is ["A","C","E","F"]
Explanation
A. Increased subcutaneous fat: Middle adulthood often sees an increase in fat deposits, particularly around the abdomen, due to changes in metabolism and hormonal shifts.
B. Increased skin turgor and moisture: Incorrect. Aging typically leads to decreased skin turgor and moisture, causing the skin to become drier and less elastic.
C. Decreased bone density: Bone density generally decreases due to reduced bone remodeling, increasing the risk of fractures and osteoporosis.
D. The skin is more elastic: Incorrect. Skin elasticity usually decreases with age, resulting in wrinkles and sagging.
E. Muscle mass gradually decreases: Muscle mass tends to decline with age, a condition known as sarcopenia, leading to reduced strength and physical capability.
F. Decreased auditory acuity: Hearing loss, particularly high-frequency hearing loss, is common as people age due to changes in the inner ear and other auditory structures
Correct Answer is A
Explanation
A. Bend at the knees when picking up an object: This technique helps distribute the weight of the object and reduces strain on the back muscles.
B. Relax her abdominal muscles when she lifts an object: Tensing the abdominal muscles can provide core support, but relaxing them while lifting can increase the risk of injury.
C. Twist at the waist when she moves an object to one side: Twisting at the waist can strain the back muscles and should be avoided.
D. Hold an object away from her body as she lifts it: Holding objects close to the body reduces strain on the back muscles and is a good technique to prevent injury.
