The nurse is conducting a physical examination of a child following a comprehensive health history. What should be the focus of the physical examination?

A. Eruption of the last four molars: This characteristic typically occurs during adolescence but may vary individually. However, it is not universal among all teenagers and does not apply to both genders equally.

B. Increased shoulder, chest, and hip widths: During adolescence, both boys and girls experience growth spurts, leading to increased shoulder, chest, and hip widths as part of their overall physical development.

C. Decreased respiratory rates of 15 to 20 breaths per minutE. Respiratory rates in teenagers generally remain within the normal adult range, typically between 12 and 20 breaths per minute. There is no consistent decrease in respiratory rates during adolescence.

D. Fully functioning sweat and sebaceous glands: Sweat and sebaceous glands are typically fully developed and functional by adolescence. This characteristic is not specific to teenagers but applies to individuals of all ages once these glands have matured.

A. "I can fit my hand between the baby and the car seat harness."

This statement indicates that the harness may not be properly snug against the infant's body, which could compromise safety.

B. "Our car seat is front-facing in the back seat."

For a 6-month-old infant, the car seat should be rear-facing to provide optimal safety in the event of a crash. Front-facing seats are typically used for older children.

C. "The car seat is rear-facing in the front passenger seat."

Rear-facing car seats should never be placed in the front passenger seat, especially if the car is equipped with airbags. The back seat is the safest location for a car seat.

D. "Our car seat is an infant model and is anchored in the car."

This statement indicates that the parent understands the importance of using an appropriate car seat for the infant's age and size and that the seat is properly installed and secured in the vehicle.
