Chapter 51 : Caring for Clients With Diabetes Mellitus Questions
Question 1 of 5
The nurse is explaining glycosylated hemoglobin testing to a diabetic client. Which of the following provides the best reason for this order?
Correct Answer: D
Rationale: Glycosylated hemoglobin (HbA1c) measures glucose bound to hemoglobin over its 120-day lifespan, reflecting long-term glucose control. It does not assess overall blood functioning, nutritional status, or cost relative to daily testing, which is still necessary for insulin-dependent clients.
Question 2 of 5
The client who is managing diabetes through diet and insulin control asks the nurse why exercise is important. Which is the best response by the nurse to support adding exercise to the daily routine?
Correct Answer: A
Rationale: Exercise enhances glucose uptake by increasing transmembrane glucose transporters in muscles, lowering blood sugar levels. While it may improve well-being and reduce insulin resistance, the primary benefit for diabetes management is improved glucose transport into cells.
Question 3 of 5
A diabetic client maintains glucose control with the use of long-acting and short-acting insulin. Which nursing instruction would be considered a priority instruction for this client?
Correct Answer: D
Rationale: Lantus and Levemir (long-acting insulins) must be administered in separate syringes, as mixing with other insulins can alter their action. Monitoring should occur before injections, and the stomach is not specifically preferred for nighttime doses; thighs are often used for slower absorption.
Question 4 of 5
A diabetic client who is controlled with insulin complains to the nurse about weight gain. Which response from the nurse explains the most likely cause of the weight increase?
Correct Answer: A
Rationale: Insulin, an anabolic hormone, promotes glucose storage as glycogen and fat, contributing to weight gain. While it improves glucose utilization and corrects faulty metabolism, these are secondary to its anabolic effects. Fluid retention is not typically associated with insulin therapy.
Question 5 of 5
A client newly diagnosed with type 1 diabetes asks the nurse why injection site rotation is important. What is the nurse's best response?
Correct Answer: B
Rationale: Rotating injection sites prevents lipodystrophy (fat buildup or breakdown), ensuring consistent insulin absorption. While infection and discomfort are concerns, they are not the primary reasons. Insulin is not injected into muscle, so muscle destruction is irrelevant.
