A nurse is caring for a client who states, "I am under a great deal of stress at work, but I am able to forget my work and concentrate on my family when I get home at night." The nurse should identify that the client is demonstrating which of the following defense mechanisms?

The correct answer is: B. Identity vs. Role Confusion.

Choice A reason:

Autonomy vs. Shame and Doubt occurs in early childhood (ages 1-3). During this stage, children develop a sense of personal control over physical skills and a sense of independence. The focus is on developing autonomy, not on the social dynamics typical of adolescence.

Choice B reason:

Identity vs. Role Confusion is the stage that occurs during adolescence (ages 12-18). In this stage, teenagers explore their independence and develop a sense of self. They may rebel against caregivers and spend more time with peers as they form their identity and navigate social roles. This stage is crucial for developing a personal identity and a sense of direction in life.

Choice C reason:

Integrity vs. Despair occurs in late adulthood (ages 65 and older). This stage involves reflecting on one's life and either coming to terms with it or feeling a sense of despair over missed opportunities. It is not relevant to the experiences of an adolescent.

Choice D reason:

Trust vs. Mistrust is the first stage of Erikson's theory, occurring in infancy (birth to 18 months). This stage focuses on developing trust when caregivers provide reliability, care, and affection. A lack of this leads to mistrust. It does not pertain to the adolescent's developmental challenges.

Choice A reason : Sitting upright unsupported is a motor skill that typically develops after a baby has gained enough strength and balance, which usually occurs around 6 months of age. Before they can sit unsupported, infants need to develop control over their head and neck muscles, as well as their upper body strength.

Choice B reason : Standing while holding on to furniture, also known as cruising, is a skill that comes later in the first year of life, usually after the infant has mastered sitting and crawling. This skill is often seen around 9 to 12 months of age as the infant's leg and core muscles become strong enough to support their weight in an upright position.

Choice C reason : Transferring an object from hand to hand is a fine motor skill that develops as an infant's hand-eye coordination improves. This skill typically emerges around 4 to 6 months of age, after the infant has developed the ability to grasp objects and has begun to explore their environment more actively with their hands.

Choice D reason : Rolling from side to side is one of the first gross motor skills that infants develop, usually occurring around 2 to 4 months of age. This skill is an important precursor to more complex movements such as sitting, crawling, and walking. It begins with the infant learning to control their head movements and then progresses to rolling over from their stomach to their back and vice versa.
