A nurse is collecting data from a 6-month-old infant in the well-child clinic.
Which of the following findings should the nurse expect?
Lateral incisors are present.
Posterior fontanel is closed.
Infant's birth weight is tripled.
Infant sits well without support.
The Correct Answer is B
A. Lateral incisors are present: At 6 months, infants typically begin teething, but the lateral incisors usually do not appear until around 9 to 13 months. The first teeth to emerge are usually the lower central incisors.
B. Posterior fontanel is closed: The posterior fontanel, or the soft spot at the back of the baby's head, typically closes by 2 to 3 months of age. Therefore, it is expected to be closed by the time the infant is 6 months old.
C. Infant's birth weight is tripled: By 6 months, infants generally double their birth weight. Tripling of birth weight is more commonly expected by the end of the first year.
D. Infant sits well without support: Most infants begin to sit without support around 7 to 9 months. At 6 months, they may sit with some support but are not yet expected to sit well independently.

Correct Answer is B
Explanation
During pregnancy, a woman needs to increase her caloric intake by approximately 300 extra calories per day.
These extra calories should come from a balanced diet of protein, fruits, vegetables, and whole grains.
Choice A is incorrect because adding an additional 500 calories/day by drinking milkshakes is not a healthy way to increase caloric intake during pregnancy.
Choice C is incorrect because doubling caloric intake is not necessary during pregnancy.
Choice D is incorrect because while it is important to watch caloric intake during pregnancy, it is also important to increase caloric intake by approximately 300 extra calories per day.
Correct Answer is D
Explanation
“You should place your baby on her back when sleeping to decrease the risk of SIDS.” According to Mayo Clinic, placing a baby on their back to sleep is one of the most important measures that can be taken to help protect a child from SIDS1.
Choice A is incorrect because there is no evidence that SIDS is directly correlated to diphtheria, tetanus, and pertussis vaccines.
Choice B is incorrect because SIDS rates have actually decreased dramatically since the American Academy of Pediatrics issued its safe sleep recommendations in 19922.
Choice C is incorrect because while sleep apnea may contribute to breathing problems, it is not considered the main cause of SIDS1.
