Which of the following findings is a manifestation of dehydration?
Presence of acrocyanosis.
Capillary refill greater than 3 seconds.
Voided four times in the past 24 hours.
Flat soft anterior fontanel.
The Correct Answer is B
Choice A rationale
Acrocyanosis is a common finding in newborns and is not a sign of dehydration. It usually resolves on its own.
Choice B rationale
A capillary refill time greater than 3 seconds can indicate dehydration in a newborn. It suggests poor perfusion and fluid status.
Choice C rationale
Voiding four times in the past 24 hours is within the normal range for a newborn and does not indicate dehydration.
Choice D rationale
A flat soft anterior fontanel is normal in newborns and does not indicate dehydration. A sunken fontanel would be a sign of dehydration. .

Choice A rationale
Warming the newborn’s heel for 5 to 10 minutes before the puncture increases blood flow, making it easier to collect a blood sample.
Choice B rationale
The outer aspect of the heel is the recommended site for puncture to avoid injury to the bone and nerves.
Choice C rationale
Leaving the heel open to the air after the puncture is not recommended as it can increase the risk of infection.

Applying an antiseptic after collecting the specimen is not necessary and can interfere with the blood sample.
Correct Answer is A
Explanation
Choice A rationale
Taking a break and walking at least once every hour during long trips helps improve circulation and reduces the risk of blood clots, which is particularly important during pregnancy.
Choice B rationale
Wearing the shoulder harness snug across the stomach is incorrect. The shoulder harness should be worn across the chest and between the breasts to avoid pressure on the abdomen.
Choice C rationale
Positioning the lap belt across the navel is incorrect. The lap belt should be placed under the belly, across the hips and pelvic bone, to avoid pressure on the uterus.
Choice D rationale
Moving the car seat forward, close to the steering wheel, is not recommended. Pregnant women should maintain a safe distance from the steering wheel to avoid injury in case of an accident.
