The nurse is performing a physical assessment on a 6-month-old baby. Which finding should the nurse understand as abnormal for this child?
The child has the beginning signs of tooth eruption.
The child is able to track and follow objects.
The child’s anterior fontanel is open.
The child’s posterior fontanel is open.
The Correct Answer is D
A. The child has the beginning signs of tooth eruption:
Teething usually begins around 4-7 months of age, so the beginning signs of tooth eruption (teething) are typical at six months.
B. The child is able to track and follow objects:
By six months, most infants can track and follow objects with their eyes, which is a normal developmental milestone for this age.
C. The child’s anterior fontanel is open:
The anterior fontanelle, the soft spot at the top of the baby's head, remains open until around 18-24 months of age, so its presence at six months is expected and considered normal.
D. The child’s posterior fontanel is open.
By six months of age, the posterior fontanelle, the soft spot located at the back of the baby's head, typically closes or is significantly smaller than it was at birth. The posterior fontanelle usually closes between 2 to 4 months of age in most infants. If it remains noticeably open by six months, it might warrant further evaluation as it could be indicative of a developmental or medical issue.

Explanation
A. The deciduous teeth falling out:
The falling out of deciduous (baby) teeth is a natural part of early childhood development and is not specifically indicative of adolescence. The loss of deciduous teeth usually occurs before the age of 12.
B. The beginning of puberty:
Puberty is the period of physical and sexual development that marks the transition from childhood to adolescence. It involves the development of secondary sexual characteristics, such as breast development in girls and facial hair growth in boys, along with other physical changes.
C. The child becoming self-supported:
Becoming self-supported is a broad concept that can occur at various stages of development and is not a specific marker of the beginning of adolescence. Adolescents may gain increasing independence, but this is a gradual process.
D. The fine motor skills fully developed:
Fine motor skills typically develop during early childhood, and the full development of these skills is not a specific marker for the beginning of adolescence. Fine motor skills involve the coordination of small muscle movements and are important for tasks like writing and drawing.
Correct Answer is ["1.75"]
Explanation
To administer the correct dose of ampicillin IM, the nurse needs to calculate the amount of solution to draw up from the vial.
The vial contains 1 g of ampicillin in 5 mL of solution, which means that each mL has 200 mg of ampicillin.
To get 350 mg of ampicillin, the nurse needs to divide 350 by 200, which gives 1.75.
Therefore, the nurse needs to draw up 1.75 mL of solution for an IM injection.
