Types and Administration Techniques Flashcards

Insulin degludec (Tresiba) is classified as an ultra-long-acting insulin. Compared to glargine, its duration of action is approximately:

Answer: More than 42 hours

Insulin degludec has a duration exceeding 42 hours, making it more flexible in dosing timing than other long-acting insulins.

A patient has an order for 'sliding scale' regular insulin. This means the dose is determined by:

Answer: The patient's blood glucose level before the dose

Sliding scale insulin orders specify different doses based on the patient's current blood glucose reading before administration.

Which of the following is an appropriate way to store an opened (in-use) insulin vial?

Answer: At room temperature for up to 28–30 days per manufacturer guidelines

Most opened insulin vials can be kept at room temperature (below 77–80°F) for 28–30 days without significant loss of potency.

When teaching a patient about insulin injection technique, the QMA should instruct them to inject into:

Answer: Subcutaneous tissue just below the skin

Subcutaneous tissue provides the correct absorption rate for insulin; intramuscular injection causes faster, less predictable absorption.

An insulin pen is primed by dialing 2 units and pressing the plunger until a drop of insulin appears. Why is priming important?

Answer: It removes air from the needle and confirms the pen is working

Priming expels any air in the needle and confirms the pen and new needle are functioning, ensuring accurate dose delivery.

Intermediate-acting NPH insulin typically peaks at:

Answer: 4–12 hours

NPH insulin generally peaks between 4 and 12 hours after injection, distinguishing it from both rapid-acting and long-acting insulins.

After administering insulin, the QMA should apply gentle pressure to the injection site. This is done to:

Answer: Prevent bruising and stop any minor bleeding

Light pressure with a dry cotton ball or gauze helps stop minor bleeding or leakage without rubbing, which could alter absorption.
