A nurse is teaching about growth and development to a parent of a 12-year-old child. The nurse should instruct the parent to expect the child to exhibit which of the following characteristics during early adolescence?

Choice A reason: The concrete operational phase typically begins around age 7 and is characterized by the development of logical thought about concrete events. This phase is not typical for preschoolers, who are usually between the ages of 3 and 5.

Choice B reason: The formal operational phase usually starts at age 11 or older. It involves abstract thinking and the ability to systematically plan for the future, which is beyond the cognitive abilities of a preschooler.

Choice C reason: The preoperational phase occurs from ages 2 to 7. During this stage, children begin to engage in symbolic play and learn to manipulate symbols, but they do not yet understand concrete logic.

Choice D reason: The sensorimotor phase is from birth to about age 2. During this stage, infants learn about the world through their senses and actions, such as looking and touching. Preschoolers have typically moved beyond this phase.

Choice A reason: Treating everyone who came into close contact with the child is essential because scabies is highly contagious. The mites that cause scabies can easily spread to others through direct skin contact or by sharing personal items.

Choice B reason: Soaking combs and brushes in boiling water for 10 minutes is a good practice to kill any mites that may be present. However, it is not the primary method of treating scabies, which requires medication.

Choice C reason: Washing the child's hair with shampoo containing ketoconazole is not a standard treatment for scabies. Ketoconazole is an antifungal medication, and scabies is caused by mites, not fungi.

Choice D reason: Applying petroleum jelly to the affected areas is not an effective treatment for scabies. Scabies requires prescription medications, such as topical permethrin or oral ivermectin, to eliminate the mites.
