Chapter 64 : Care of Patients with Diabetes Mellitus Questions
Question 1 of 5
After teaching a client who is newly diagnosed with type 2 diabetes mellitus, the nurse assesses the client's understanding. Which statement made by the client indicates a need for additional teaching?
Correct Answer: C
Rationale: Eliminating carbohydrates is incorrect; complex carbohydrates should be included in a diabetic diet. Protein reduction may be needed with microalbuminuria, but not elimination. The other statements are correct.
Question 2 of 5
A nurse reviews laboratory results for a client with diabetes mellitus who is prescribed an intensified insulin regimen: Fasting blood glucose: 75 mg/dL, Postprandial blood glucose: 200 mg/dL, Hemoglobin A1c level: 5.5%. How should the nurse interpret these laboratory findings?
Correct Answer: B
Rationale: These values (fasting glucose 75 mg/dL, A1c 5.5%) indicate good glycemic control in an intensified insulin regimen. Postprandial glucose of 200 mg/dL is slightly high but not indicative of ketoacidosis, hyperglycemia risk, or insulin resistance.
Question 3 of 5
A nurse prepares to administer insulin to a client at 1800. The client's medication administration record contains the following information: Insulin glargine: 12 units daily at 1800, Regular insulin: 6 units QID at 0600, 1200, 1800, 2400. Based on the client's medication administration record, which action should the nurse take?
Correct Answer: A
Rationale: Insulin glargine cannot be mixed with other insulins. Administering glargine first, followed by regular insulin as separate injections, is correct to avoid mixing and ensure proper action.
Question 4 of 5
A nurse is teaching a client with diabetes mellitus who asks, 'Why is it necessary to maintain my blood glucose levels no lower than about 60 mg/dL?' How should the nurse respond?
Correct Answer: B
Rationale: Because the brain cannot synthesize or store significant amounts of glucose, a continuous supply from the body's circulation is needed to meet the fuel demands of the central nervous system. The nurse should educate the client to prevent hypoglycemia. The body can use other sources of fuel, including fat and protein, and glucose is not directly involved in the production of red blood cells. Glucose in the blood does not directly prevent lactic acid formation.
Question 5 of 5
A nurse reviews laboratory results for a client with diabetes mellitus who presents with polyuria, lethargy, and a blood glucose of 500 mg/dL. Which laboratory result should the nurse correlate with the client's polyuria?
Correct Answer: D
Rationale: Hyperglycemia causes hyperosmolarity of extracellular fluid, leading to polyuria from osmotic diuresis. The client's serum osmolarity is high, which correlates with polyuria. Serum sodium would be expected to be high due to dehydration, not low. Serum creatinine and urine ketone bodies are not directly related to polyuria in this context.
