Chapter 51 : Caring for Clients With Diabetes Mellitus Questions
Question 1 of 5
The client asks the nurse if dipstick of urine can be used for monitoring glucose levels. Which is the best response by the nurse?
Correct Answer: C
Rationale: Blood testing via glucometer is the most accurate method for monitoring glucose levels, as urine dipsticks only detect glucose above the renal threshold, which is less precise. Urine dipsticks can detect both glucose and ketones but are not the preferred method for ongoing management.
Question 2 of 5
A client with type 1 diabetes mellitus is receiving short-acting insulin to maintain control of blood glucose levels. In providing glucometer instructions, the nurse would instruct the client to use which site for most accurate findings?
Correct Answer: A
Rationale: The fingertip provides the most accurate blood glucose readings due to its rich blood supply and minimal lag in glucose levels compared to alternate sites like the arm or thigh, which are less reliable for tight glucose control.
Question 3 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 4 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 5 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.
