The nurse has seen a 15-year-old girl and a 16-year-old boy during health surveillance visits. Which physical characteristics would be seen in both teenagers?
Eruption of the last four molars
Increased shoulder, chest, and hip widths
Decreased respiratory rates of 15 to 20 breaths per minute
Fully functioning sweat and sebaceous glands
The Correct Answer is B
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.

Correct Answer is C
Explanation
A. The child exhibits plantar grasp reflex: The presence of the plantar grasp reflex at 10 months
is appropriate and not cause for concern. This reflex typically diminishes by around 9 months but can persist slightly longer in premature infants.
B. The child has doubled his birth weight: Doubling birth weight by around 6 months is a normal developmental milestone, and achieving this by 10 months is appropriate, indicating healthy growth.
C. No primary teeth have erupted yet: The absence of primary teeth by 10 months, especially in a preterm infant, may indicate a delay in dental development and should prompt further evaluation by a healthcare provider.
D. The child's head circumference is 49.53 cm: The head circumference of 49.53 cm falls within the typical range for a 10-month-old infant and is not inherently concerning.
Correct Answer is B
Explanation
A. Has a fear of strangers: Fear of strangers typically emerges around 6 to 9 months of age as part of normal social development. While it indicates cognitive and emotional growth, it does not necessarily warrant further evaluation unless it is excessive or accompanied by other concerning behaviors.
B. Uses a unidextrous grasp: By 7 months, infants typically develop a more refined pincer grasp, where they can pick up small objects using the thumb and forefinger (bidextrous grasp). A unidextrous grasp (using only one hand) may suggest a delay in fine motor development and could warrant further evaluation by a healthcare provider.
C. Babbles one-syllable sounds: Babbling is a typical milestone in language development for
infants around 6 to 9 months of age. One-syllable babbling is expected at this stage and does not necessarily indicate a need for further evaluation.
D. Shows preferences towards foods: Developing food preferences is part of normal feeding behavior for infants. While it is important to ensure a balanced diet, showing preferences towards certain foods is not typically a cause for concern at this age.
