A nurse is caring for an 18-month-old toddler who has been hospitalized for 10 days. After the toddler's mother leaves the room, the nurse observes the toddler sitting quietly in the cornerof the crib, sucking her thumb. When the nurse approaches the crib, the toddler turns away from the nurse. The nurse should understand that these behaviors indicate which of the following developmental reactions?

B. Trust vs. mistrust: This is the first stage, occurring from birth to approximately 18 months of age, where infants learn to trust or mistrust their caregivers and the world based on

whether or not their basic needs—such as food, affection, and safety—are met.

E. Autonomy vs. shame and doubt: The second stage, from roughly 18 months to 3 years, is when toddlers begin to assert their independence. If caregivers encourage self-sufficient behavior, toddlers learn to be autonomous; if not, they may develop feelings of shame and doubt about their abilities.

C. Initiative vs. guilt: During the preschool years, from about 3 to 6 years, children begin to assert power and control over their world through directing play and other social interactions.

Successful completion of this stage leads to a sense of initiative, while failure results in feelings of guilt.

A. Industry vs. inferiority: Occurring from age 6 to puberty, this stage is characterized by the child's navigation of social demands and learning to develop a sense of pride in their accomplishments and abilities. If this stage is managed well, the child will feel industrious; if not, they may feel inferior.

D. Identity vs. role confusion: The final stage in Erikson's model for adolescence, from puberty to young adulthood, involves developing a sense of self and personal identity. Success leads to an ability to stay true to oneself, while failure leads to role confusion and a weak sense of self.

A. A child who is brought to the emergency room with labored breathing: Labored breathing can indicate a serious respiratory problem that requires immediate assessment and intervention.

Conducting a comprehensive health history is crucial to gather information about the child's medical history, current symptoms, and any potential underlying conditions that could be contributing to the breathing difficulty.

B. A child who is a new client in a pediatric officE. While it is important to obtain a comprehensive health history for new clients in a pediatric office, it may not require immediate attention unless the child presents with acute symptoms or concerns.

C. A child who is a routine client and presents with signs of a sinus infection: While a child presenting with signs of a sinus infection may require a comprehensive health history to guide treatment, it may not necessitate immediate attention unless the symptoms are severe or accompanied by complications.

D. A child whose condition is improving: If a child's condition is improving, conducting a comprehensive health history may not be immediately necessary unless there are lingering concerns or new symptoms that arise during follow-up visits.
