Question

The nurse would expect to see which signs for a client with a daily glucose average of 315 mg/dL? Select all that apply.

Answers

  1. Increased urine output
    • Rationale:

      This answer is correct because increased urine output is a sign of hyperglycemia. This occurs as the body attempts to get rid of the excess glucose. It is called polyuria.

  2. Anxious behavior
    • Rationale:

      This answer is not correct because this is a sign of hypoglycemia. Other signs of hypoglycemia include headache, irritableness, weakness, and sweats.

  3. Greater appetite
    • Rationale:

      This answer is correct because this is a sign of hyperglycemia. In hyperglycemia, glucose cannot enter the cells to be used for energy. This causes polyphagia, and does not go away after consuming food.

  4. Extreme thirst
    • Rationale:

      This answer is correct because of the polyuria the body experiences during hyperglycemia. The body tells the brain it needs to replenish the fluids it is losing. This creates thirst, or polydipsia.

  5. Irritable demeanor
    • Rationale:

      This answer is not correct because this is a sign of hypoglycemia. Other signs of hypoglycemia include headache, anxiousness, weakness, and sweats.

Overview

A glucose over 315 mg/dL is hyperglycemia. Signs of hyperglycemia include polyuria, polydipsia, and polyphagia.

Explanation

Learning Outcomes

Hyperglycemia is a glucose over 115 mg/dL. Signs of hyperglycemia include polyuria, polydipsia, and polyphagia. Polyuria occurs as a result of the body attempting to rid the excess glucose. Polydipsia ensues due to the polyuria. Since the glucose cannot enter the cells to be used for energy, excessive hunger occurs. This is called polyphagia. Hypoglycemia is a glucose under 70 mg/dL. These signs include headache, irritability, weakness, anxiousness, and sweating.

Test Taking Tip

Remember: “Cold and clammy, give them candy”; “Hot and dry, sugar is high.”
