Which insulin administration route has the slowest onset of action?
Intramuscular (IM) injection
Subcutaneous injection
Intravenous (IV) infusion
Inhalation
The Correct Answer is B

Incorrect choices:
a. IM injection is not a common route for insulin administration and has a slower onset than subcutaneous injection.

Incorrect choices:
a. Rotating injection sites between different anatomical areas helps prevent lipohypertrophy and ensures consistent absorption.
c. Insulin vials can be kept at room temperature for up to 28 days once in use, but they should be stored away from direct sunlight and extreme temperatures.

Correct Answer is B
Explanation
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.
