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 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.
Correct Answer is C
Explanation
Choice A rationale
Agitation is not a common adverse effect of magnesium sulfate therapy. It is more likely to be caused by other factors.
Choice B rationale
Polyuria, or excessive urination, is not a common adverse effect of magnesium sulfate therapy. It is more likely to be caused by other factors.
Choice C rationale
Hyporeflexia, or diminished reflexes, is a significant adverse effect of magnesium sulfate therapy. It indicates magnesium toxicity and requires immediate attention.
Choice D rationale
Tachypnea, or rapid breathing, is not a common adverse effect of magnesium sulfate therapy. It is more likely to be caused by other factors.
