What is the recommended technique for insulin injection?
Insert the needle at a 90-degree angle.
Pinch the skin and insert the needle at a 45-degree angle.
Insert the needle at a 30-degree angle.
Press the needle gently against the skin and release the medication quickly.
The Correct Answer is B
Pinch the skin and insert the needle at a 45-degree angle. This technique helps ensure proper subcutaneous injection and absorption of insulin.
Incorrect choices:
a. Inserting the needle at a 90-degree angle may result in intramuscular injection, leading to rapid absorption and potential hypoglycemia.
c. Inserting the needle at a 30-degree angle may result in shallow injection and inadequate insulin absorption.
d. Pressing the needle against the skin and releasing quickly may result in the medication leaking out of the injection site.

Correct Answer is A
Explanation
Drawing up rapid-acting insulin before intermediate-acting insulin prevents contamination of the rapid-acting insulin vial with the longer-acting insulin.
Incorrect choices:
b. Drawing up intermediate-acting insulin first can contaminate the vial with rapid-acting insulin, potentially altering dosing accuracy.
c. The order in which insulin is drawn up does matter to prevent contamination.
d. Regular insulin is not commonly used for injection in routine insulin therapy.
Correct Answer is B
Explanation
Rotating injection sites within the same anatomical area (e.g., abdomen, thigh) helps prevent lipohypertrophy and ensures consistent insulin absorption.
Incorrect choices:
a. Injecting into the same site each time can lead to lipohypertrophy and uneven insulin absorption.
c. While the abdomen is a common injection site, rotating within the same area is essential to prevent tissue damage.
d. Insulin absorption rates are similar across different anatomical sites, so there is no "fastest" absorption site.
