Final answer:
A client with a blood glucose level of 55 mg/dL would likely have cold, clammy skin.
Step-by-step explanation:
When a client has a blood glucose level of 55 mg/dL, a nurse would expect to find cold, clammy skin as a sign or symptom on assessment. This is because hypoglycemia (low blood glucose) can cause vasoconstriction, resulting in reduced blood flow to the skin and causing it to feel cold and clammy.
