Final answer:
Shakiness and diaphoresis are manifestations of hypoglycemia, which is a condition where blood sugar levels are lower than normal, leading to various symptoms like shaking and sweating. Polyuria is associated with hyperglycemia, while bradycardia is not typically related to blood sugar levels, and hyperglycemia means high blood sugar.
Step-by-step explanation:
The nurse should identify shakiness and diaphoresis as manifestations of hypoglycemia. Hypoglycemia occurs when the blood sugar levels drop below normal, leading to symptoms such as shakiness, sweating (diaphoresis), confusion, irritability, dizziness, and feeling weak or jittery. The other options provided do not describe hypoglycemia. Polyuria is more typically associated with hyperglycemia or diabetes insipidus, which is characterized by frequent urination. Bradycardia is not a common symptom of hypoglycemia and hyperglycemia refers to high, not low, blood sugar levels.
