A nurse is assessing the fontanels of an 8-month-old infant.
Which of the following findings should the nurse recognize as an expected finding?
The anterior fontanel is open.
The posterior fontanel is open.
Both fontanels show molding.
Both fontanels are the same size.
The Correct Answer is A
Choice A rationale:
The anterior fontanel is open in an 8-month-old infant. The anterior fontanel, located at the top of the baby's head where the skull bones have not yet fused, typically closes between 12 to 18 months of age. It is a normal finding in an 8-month-old infant.
Choice B rationale:
The posterior fontanel closes earlier than the anterior fontanel, usually within the first few months of life. It is a smaller diamond-shaped area located at the back of the baby's head. It is not expected to be open in an 8-month-old infant.
Choice C rationale:
Molding refers to the shaping of the fetal head during passage through the birth canal. It can cause temporary changes in the shape of the baby's skull. By 8 months of age, molding is not an expected finding as the skull bones have had time to return to their normal shape.
Choice D rationale:
Both fontanels being the same size is not a typical finding. The anterior fontanel is larger than the posterior fontanel, and their sizes are proportional. Any significant deviation from this proportion could indicate abnormal skull development and should be further assessed.

Correct Answer is C
Explanation
The correct answer is choiceC. “Have your child drink a small glass of water after swallowing the medication.”
Choice A rationale:
Adding digoxin to a half-cup of juice is not recommended because it can affect the absorption of the medication.It is best to give digoxin on an empty stomach or with a small amount of food if necessary.
Choice B rationale:
Limiting potassium intake is incorrect.In fact, maintaining adequate potassium levels is important because low potassium levels can increase the risk of digoxin toxicity.
Choice C rationale:
Having the child drink a small glass of water after taking the medication helps ensure that the medication is swallowed completely and reduces the risk of esophageal irritation.
Choice D rationale:
Repeating the dose if the child vomits within 1 hour is not recommended. If a dose is vomited, it should not be repeated to avoid the risk of overdose.The next dose should be given at the regular scheduled time.
