When describing the various changes that occur in organ systems during adolescence, what would the nurse include?
Significant increase in brain size
Ossification completed later in girls
Decrease in heart rate
Decrease in activity of sebaceous glands
The Correct Answer is B
A. Significant increase in brain sizE. While brain development continues during adolescence, the most significant increase in brain size occurs during early childhood rather than adolescence.
B. Ossification completed later in girls: Ossification, the process of bone formation, typically continues into late adolescence or early adulthood, and completion may occur later in girls compared to boys. This process contributes to changes in height and bone density during adolescence.
C. Decrease in heart ratE. During adolescence, there may be some changes in heart rate due to
the influence of hormones and physical growth, but a decrease in heart rate is not a consistent or universal characteristic of this developmental stage.
D. Decrease in activity of sebaceous glands: Adolescence is typically associated with an increase rather than a decrease in the activity of sebaceous glands, leading to increased oil production and the potential for acne development. Hormonal changes during puberty stimulate the sebaceous
glands, contributing to changes in skin texture and appearance.

Correct Answer is B
Explanation
A. At 3 months, infants are not expected to have the fine motor skills necessary to pick up objects with their fingers.
B. By 3 months, infants should be able to lift their head and chest during tummy time, and the inability to do so could indicate developmental delays or other health issues.
C. Infants typically cannot sit without support until they are around 6 months old.
D. The ability to bring objects to the mouth develops around 4 months of age, so it is not expected for a 3-month-old infant to do this consistently.
Correct Answer is A
Explanation
A. "This is a primitive reflex known as the palmar grasp.": The palmar grasp reflex is a primitive reflex observed in newborns where they automatically grasp onto objects (or fingers) that touch
their palms. This reflex typically disappears by around 6 months of age.
B. "This is a protective reflex known as rooting.": Rooting is a reflex where newborns turn their head and open their mouth in response to cheek or mouth stimulation, facilitating breastfeeding. It is not related to grasping objects with the hands.
C. "This is a primitive reflex known as the plantar grasp.": The plantar grasp reflex is similar to the palmar grasp but occurs when pressure is applied to the sole of the foot. It is unrelated to grasping objects with the hands.
D. "This is a protective reflex known as the Moro reflex.": The Moro reflex, also known as the startle reflex, involves the newborn's arms and legs extending and then flexing in response to a sudden movement or loud noise. It is not related to grasping objects with the hands.
