A nurse is collecting data on a newborn who is 1 day old.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.

Correct Answer is C
Explanation
Choice A rationale
Administering NSAIDs every 4 to 6 hours is not a primary measure to prevent thrombophlebitis. NSAIDs are used for pain relief and inflammation reduction, but they do not directly prevent blood clots.
Choice B rationale
Applying elastic stockings before the client gets out of bed can help prevent blood clots by promoting blood flow in the legs. However, this measure alone is not sufficient to prevent thrombophlebitis.
Choice C rationale
Ambulation, or walking, is one of the most effective measures to prevent thrombophlebitis. It promotes circulation and prevents blood from pooling in the legs, reducing the risk of clot formation.
Choice D rationale
Applying warm, moist packs to the client’s lower legs can help relieve pain and inflammation but does not directly prevent thrombophlebitis. This measure is more supportive rather than preventive.
Correct Answer is A
Explanation
Choice A rationale
A positive Babinski reflex is characterized by the fanning out of the toes and the upward movement of the big toe when the sole of the foot is stroked. This reflex is normal in infants up to 2 years old and indicates an immature central nervous system. The presence of this reflex in older children or adults can indicate neurological issues.
Choice B rationale
Curling in of the toes when the sole of the foot is stroked is indicative of the plantar grasp reflex, not the Babinski reflex. The plantar grasp reflex is a different neurological response and does not indicate the same neurological development as the Babinski reflex.
Choice C rationale
No response when the sole of the foot is stroked could indicate a lack of neurological response or an issue with the sensory or motor pathways. This is not characteristic of a positive Babinski reflex and could be a sign of neurological impairment.
Choice D rationale
The big toe bending down when the sole of the foot is stroked is a normal response in older children and adults, known as the plantar reflex. This response indicates a mature central nervous system and is not characteristic of a positive Babinski reflex in infants.
