The adolescent develops a sense of self and personal identity. Which psychosocial stage is this individual experiencing?

Choice A reason: This is not a statement that shows an understanding of safety. A fluffy pillow can pose a suffocation risk for a 10-month old baby, who may not be able to move their head away from it. The nurse should educate the parent on the safe sleep practices for infants, such as placing the baby on their back, using a firm and flat surface, and avoiding soft bedding and toys in the crib.

Choice B reason: This is not a statement that shows an understanding of safety. A car seat on the table can be unstable and fall off, causing injury to the baby. The nurse should instruct the parent on the proper use and installation of the car seat, such as securing it in the back seat of the car, facing the rear, and using the harness straps and clips correctly.

Choice C reason: This is not a statement that shows an understanding of safety. Whole milk is not recommended for a 10-month old baby, who may not be able to digest it well and may develop an allergy or intolerance. The nurse should advise the parent on the appropriate nutrition for infants, such as breastfeeding or formula feeding until 12 months, and introducing solid foods gradually and with caution.

Choice D reason: This is the best answer. A crib mattress in the low position is safer for a 10-month old baby, who may be able to pull themselves up and try to climb out of the crib. The nurse should commend the parent on this action and remind them to check the crib for any hazards, such as loose screws, gaps, or sharp edges.

Choice A reason: This is not the most critical stage for developing a healthy self-concept. Infancy is the stage of life from birth to 18 months, where the main psychosocial task is to develop trust versus mistrust. The infant's self-concept is not fully formed yet, but depends on the quality of the caregiver-infant relationship.

Choice B reason: This is the best answer. Adolescence is the stage of life from 12 to 18 years, where the main psychosocial task is to develop identity versus role confusion. The adolescent's self-concept is challenged by physical, cognitive, emotional, and social changes. The adolescent needs to explore and integrate different aspects of their self, such as their values, beliefs, goals, and roles. A healthy self-concept will help the adolescent to achieve a sense of identity, autonomy, and competence.

Choice C reason: This is not the most critical stage for developing a healthy self-concept. Middle adulthood is the stage of life from 40 to 65 years, where the main psychosocial task is to develop generativity versus stagnation. The middle adult's self-concept is influenced by their achievements, responsibilities, and relationships. The middle adult needs to find meaning and purpose in their life by contributing to society and the next generation. A healthy self-concept will help the middle adult to cope with the challenges of aging, work, and family.

Choice D reason: This is not the most critical stage for developing a healthy self-concept. Late adulthood is the stage of life from 65 years and older, where the main psychosocial task is to develop integrity versus despair. The late adult's self-concept is based on their life review and evaluation. The late adult needs to accept their past and present, and face their mortality. A healthy self-concept will help the late adult to achieve a sense of wisdom, dignity, and satisfaction.
