The practical nurse (PN) is observing a client self-administering the noon dose of subcutaneous insulin. What step of the injection technique should the practical nurse (PN) reteach?
Selects the same site that was used for the previous injection.
Inserts the needle at a 90 degree angle to the skin surface.
Uses a circular action when applying an alcohol pad to the site.
Injects air into the insulin vial to displace the dose.
The Correct Answer is A
A. Selects the same site that was used for the previous injection: The PN should reteach this step because insulin injection sites must be rotated to prevent lipohypertrophy and uneven absorption. Repeated use of the same site can lead to tissue thickening, altered insulin uptake, and unpredictable glucose control.
B. Inserts the needle at a 90 degree angle to the skin surface: A 90-degree angle is appropriate for most adults using short insulin needles, ensuring proper subcutaneous delivery. The angle may be adjusted only for very thin clients or when using longer needles.
C. Uses a circular action when applying an alcohol pad to the site: Cleaning the site in a circular motion from the center outward helps reduce bacterial contamination before injection. This technique is correct and should continue to be reinforced.
D. Injects air into the insulin vial to displace the dose: Injecting air equal to the insulin dose into the vial helps maintain pressure balance and ensures accurate dose withdrawal. This is a proper and necessary step in insulin preparation.

Correct Answer is ["1"]
Explanation
Determine the volume to administer in milliliters (mL).
Prescribed dose = 30 mg
Available concentration = 30 mg per 15 mL
Volume (mL) to administer = (Prescribed dose (mg) / Available concentration (mg)) x Available volume (mL)
= (30 mg / 30 mg) x 15 mL
= 15 mL.
Convert the volume from milliliters (mL) to tablespoons (tbsp).
Conversion factor: 1 tablespoon (tbsp) = 15 mL
Volume (tbsp) = (Volume in mL / Conversion factor)
= (15 mL / 15 mL/tbsp)
= 1 tbsp.
Correct Answer is A
Explanation
A. Confirm that the client is using the correct technique: Observing a return demonstration allows the PN to verify that the client can perform pursed-lip breathing correctly. Confirming proper technique ensures the client can use this method effectively to improve ventilation and control dyspnea.
B. Review each step of the breathing technique with the client: Reviewing steps is appropriate if the client demonstrates errors or uncertainty. If the demonstration is correct, repeated review is unnecessary and may not add value.
C. Demonstrate how to breathe in more slowly and effectively: Additional demonstration is only needed if the client’s technique is incorrect or inefficient. Unneeded repetition may cause confusion when the client is already performing correctly.
D. Remind the client to cough deeply to loosen secretions: While coughing can help clear secretions, it is not part of pursed-lip breathing instruction. Introducing unrelated techniques may distract from mastering the intended breathing method.
