A nurse is collecting data from a newborn.
The nurse should recognize that which of the following images demonstrates a positive Babinski reflex?
Image of a newborn with toes fanning out when the sole of the foot is stroked.
Image of a newborn with toes curling in when the sole of the foot is stroked.
Image of a newborn with no response when the sole of the foot is stroked.
Image of a newborn with the big toe bending down when the sole of the foot is stroked.
The Correct Answer is A
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.

Explanation
The nurse should plan toB. check the client’s blood glucose levelandA. obtain a urine sample to test for ketones.
Explanation:
- Check the client’s blood glucose level: Given the client’s history of type 1 diabetes mellitus and her current symptoms (diaphoresis, clammy skin, headache, nausea, and weakness), it is crucial to check her blood glucose level to rule out hypoglycemia or hyperglycemia, despite the recent blood glucose reading of 120 mg/dL.
- Obtain a urine sample to test for ketones: Testing for ketones is important in diabetic patients, especially when they present with symptoms that could indicate diabetic ketoacidosis (DKA), such as nausea, weakness, and a history of type 1 diabetes.
