QUESTIONS WITH COMPLETE SOLUTIONS

Question 1
Q: What is the primary action of insulin in the body?
A: Insulin primarily facilitates the uptake of glucose into cells, particularly muscle and fat
cells, and helps regulate blood glucose levels.
Rationale: Insulin is a hormone produced by the pancreas that plays a crucial role in glucose
metabolism. By promoting glucose uptake and inhibiting gluconeogenesis, insulin helps to
lower blood glucose levels.
Question 2
Q: What are the different types of insulin based on their duration of action?
A: The main types of insulin include rapid-acting, short-acting, intermediate-acting, and
long-acting insulins.
Rationale: Understanding the different types of insulin is essential for effective diabetes
management. Rapid-acting insulins start working within minutes, while long-acting insulins
provide a steady level of insulin over 24 hours.
Question 3
Q: When should a nurse administer rapid-acting insulin?
A: Rapid-acting insulin should be administered 15 minutes before meals or immediately after
meals.
Rationale: Rapid-acting insulins (e.g., insulin lispro, insulin aspart) are designed to control
postprandial blood glucose levels effectively. Administering it at the right time is crucial to
prevent hyperglycemia after meals.
Question 4
Q: What is the correct technique for drawing up mixed insulin in one syringe?
,A: Always draw up the clear insulin (regular or rapid-acting) first, followed by the cloudy
insulin (intermediate-acting).
Rationale: This technique prevents contamination of the clear insulin with the cloudy
insulin, which could alter the effectiveness of the rapid-acting insulin.
Question 5
Q: What is the proper site for subcutaneous insulin injection?
A: Common sites for subcutaneous injection include the abdomen, thigh, and upper arm.
Rationale: Subcutaneous injections allow for the slow absorption of insulin. The abdomen is
often preferred for its consistent absorption rates and ease of access.
Question 6
Q: Why is it important to rotate injection sites?
A: Rotating injection sites helps prevent lipodystrophy and ensures consistent absorption of
insulin.
Rationale: Frequent use of the same injection site can lead to scar tissue, which may affect
how insulin is absorbed and increase the risk of uneven blood glucose control.
Question 7
Q: How should a nurse respond if a patient reports hypoglycemic symptoms after insulin
administration?
A: The nurse should assess the patient's blood glucose level and administer a fast-acting
carbohydrate if hypoglycemia is confirmed.
Rationale: Quick treatment of hypoglycemia with fast-acting carbohydrates (e.g., glucose
tablets, juice) is critical to prevent severe complications and restore normal blood glucose
levels.
Question 8
Q: What are the signs of insulin resistance?
, A: Signs of insulin resistance include high fasting blood glucose levels, weight gain, and
acanthosis nigricans.
Rationale: Insulin resistance is characterized by the body’s inability to respond effectively to
insulin, leading to elevated blood sugar levels and other metabolic changes.
Question 9
Q: What is the recommended storage method for insulin vials?
A: Insulin vials should be stored in the refrigerator until opened; after opening, they can be
kept at room temperature for up to 28 days.
Rationale: Proper storage prevents degradation of the insulin, ensuring its effectiveness.
Insulin should not be frozen, as this can damage its structure.
Question 10
Q: What is the significance of the "clear before cloudy" rule in insulin administration?
A: This rule ensures that the clear insulin does not become contaminated with the cloudy
insulin.
Rationale: Following this guideline minimizes the risk of introducing the slower-acting
insulin particles into the rapid-acting insulin vial, which could impair the efficacy of the
medication being administered.
Question 11
Q: What is the purpose of using an insulin pen?
A: Insulin pens provide a convenient and accurate way to deliver insulin, making it easier for
patients to self-administer their doses.
Rationale: Insulin pens simplify the injection process and improve dosage accuracy
compared to traditional syringes, enhancing patient compliance and comfort.
Question 12
Q: How should insulin be mixed if a patient is prescribed both rapid-acting and long-acting
insulin?
A: Rapid-acting insulin should be drawn up first, followed by the long-acting insulin.
