1. During clinical prioritization, which finding is most characteristic of symptomatic hyperglycemia?
A) Hemoptysis and cyanosis
B) Diaphoresis and tremor
C) Bradycardia and constipation
D) Polyuria, polydipsia, and polyphagia
Correct Answer: Polyuria, polydipsia, and polyphagia
Rationale: Hyperglycemia causes osmotic diuresis, producing polyuria and thirst. Cellular glucose deprivation
can also increase hunger. Clinical judgment also requires distinguishing expected findings from signs of
deterioration and reassessing after intervention.
2. A nurse is caring for a patient whose presentation requires application of this concept. which finding is
most characteristic of symptomatic hyperglycemia?
A) Polyuria, polydipsia, and polyphagia
B) Diaphoresis and tremor
C) Bradycardia and constipation
D) Hemoptysis and cyanosis
Correct Answer: Polyuria, polydipsia, and polyphagia
Rationale: Hyperglycemia causes osmotic diuresis, producing polyuria and thirst. Cellular glucose deprivation
can also increase hunger. In practice, the nurse should connect this concept with the patient's current
assessment, laboratory data, medication effects, safety risks, and response to treatment.
3. During clinical prioritization, which finding most strongly suggests hypoglycemia?
A) Polyuria and dry skin
B) Diaphoresis, tremor, and confusion
C) Jaundice and ascites
D) Bradypnea and edema
Correct Answer: Diaphoresis, tremor, and confusion
Rationale: Hypoglycemia triggers adrenergic symptoms such as sweating and tremor and neuroglycopenic
symptoms such as confusion. Clinical judgment also requires distinguishing expected findings from signs of
deterioration and reassessing after intervention.

Correct Answer: Diaphoresis, tremor, and confusion
Rationale: Hypoglycemia triggers adrenergic symptoms such as sweating and tremor and neuroglycopenic
symptoms such as confusion. In practice, the nurse should connect this concept with the patient's current
assessment, laboratory data, medication effects, safety risks, and response to treatment.
5. During clinical prioritization, which laboratory value reflects average glycemic control over about 2 to 3
months?
A) Serum sodium
B) Troponin
C) Hemoglobin A1C
D) INR
Correct Answer: Hemoglobin A1C
Rationale: A1C reflects the percentage of glycated hemoglobin and provides an estimate of average blood
glucose over preceding weeks. Clinical judgment also requires distinguishing expected findings from signs of
deterioration and reassessing after intervention.

glucose over preceding weeks. In practice, the nurse should connect this concept with the patient's current
assessment, laboratory data, medication effects, safety risks, and response to treatment.
7. During clinical prioritization, what is the defining metabolic problem in diabetic ketoacidosis?
A) Isolated hypernatremia
B) Excess insulin causing alkalosis
C) Insulin deficiency causing hyperglycemia, ketosis, and metabolic acidosis
D) Hyperglycemia without ketone production
Correct Answer: Insulin deficiency causing hyperglycemia, ketosis, and metabolic acidosis
Rationale: Severe insulin deficiency promotes lipolysis and ketone formation while hyperglycemia causes
osmotic diuresis. Clinical judgment also requires distinguishing expected findings from signs of deterioration
and reassessing after intervention.
