A nurse is assessing a 12-month-old infant who is brought to the clinic by the parents for a well-child visit. The nurse reviews the infant's health history and notes that the infant weighed 8 lb at birth. When assessing the infant's weight at this visit, the nurse would anticipate that the infant would weigh approximately how much at this time?

Answer and Explanation

The Correct Answer is C

A. 20 lbs: This is a plausible estimate. By 12 months, an infant's birth weight typically triples. Therefore, an 8 lb birth weight would approximately translate to 24 lbs at 12 months.

B. 32 lbs: This estimate is too high. If an infant's birth weight triples by 12 months, an 8 lb birth weight would not be expected to reach 32 lbs.

C. 24 lbs: An infant's weight usually triples by their first birthday. Therefore, an infant born weighing 8 lbs would be expected to weigh about 24 lbs at 12 months.

D. 16 lbs: This is an underestimate. An 8 lb infant would double their birth weight by about 4 to 6 months, and by 12 months, they would typically have tripled their birth weight to around 24 lbs.

Correct Answer is B

Explanation

A. Pincer grasp: The pincer grasp, which involves using the thumb and forefinger to pick up small objects, typically develops around 8 to 12 months of age, not at 4 months.

B. Rolls from tummy to back: At 4 months, many infants start to develop the ability to roll from their tummy to their back. This is a typical milestone for this age and reflects developing motor skills.

C. Walks with support: Walking with support usually begins around 9 to 12 months of age, much later than 4 months.

D. Rolls from back to tummy: Rolling from back to tummy typically occurs a bit later, often around 5 to 6 months. At 4 months, rolling from tummy to back is the more expected milestone.

A. Concrete operational B. Sensorimotor C. Formal operational D. Preoperational

Correct Answer is B

Explanation

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.
