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
Choice A rationale:
Soaking in a warm bath every day is not a preventative measure for chronic urinary tract infections. Warm baths might provide temporary relief for discomfort but do not prevent UTIs.
Choice B rationale:
Taking an oral estrogen supplement is not a standard preventative measure for chronic urinary tract infections. Estrogen therapy might be recommended for postmenopausal women with recurrent UTIs, but it's not a general preventive method for all women.
Choice C rationale:
"Drink 2 liters of water per day." This is the correct answer. Staying well-hydrated is essential to prevent urinary tract infections. Drinking an adequate amount of water can help flush out bacteria from the urinary system, reducing the risk of infections. The normal range for daily water intake varies but is generally around 2-3 liters or eight 8-ounce glasses per day.
Choice D rationale:
Emptying the bladder every 6 hours is a good practice, but it might not be sufficient for someone prone to chronic UTIs. Regular and frequent urination can help prevent the buildup of bacteria in the urinary tract. However, specific time intervals might vary from person to person, so a fixed 6-hour rule might not apply to everyone.
Correct Answer is A
Explanation
Explanation: Evisceration is a surgical emergency that occurs when the abdominal contents protrude through the incision site. The nurse should instruct the client to lie supine with his knees flexed to reduce tension on the wound and prevent further damage.
The nurse should also cover the wound with a moist sterile dressing and notify the surgeon immediately. Positioning the client in semi-Fowler's position, covering the wound with a dry sterile dressing, or covering the wound with a transparent dressing are not appropriate actions for evisceration.
