The practical nurse (PN) is observing a client self-administering a dose

if subcutaneousinsulin. What step of the injection technique should

the practical nurse (PN) reteach?

a. Injects air into the insulin vial to displace the dose

b. Selectsthe same site that was used for the previous injection

c. Inserts the needle at a 90-degree angle to the skin surface

d. Uses a circular motion when applying an alcohol pad to the site

Rationale: The PN should reteach the client to rotate the NOON site to a site

other than the same one used for the AM dose. Different sites used throughout

the day may provide a varying rate of absorption related to activity. Intra-site

rotation is recommended for the doseused during one specific time of the day.

The other choices are acceptable techniques for subcutaneous injection of

insulin.
