Which localized reaction should the nurse assess for if a client reports itching at the injection site after an insulin shot?

When a client reports itching at the injection site after receiving an insulin shot, the nurse should specifically assess for pruritis. Pruritis refers to an intense itching sensation that often indicates a localized allergic reaction or sensitivity to the insulin or other components in the injection site. This can occur due to various factors such as irritation from the needle, reaction to the insulin itself, or even the preservatives used in the formulation.

Recognizing pruritis is essential because it helps the nurse evaluate whether this is a mild, temporary reaction or if further investigation and potential management are necessary. Monitoring localized reactions like pruritis is crucial in diabetes management, as it can affect patient comfort and compliance with insulin therapy.

In the context provided, while other symptoms such as drowsiness, euphoria, and hypertension can be relevant to different medical situations, they do not directly correlate with the sensation of itching at an injection site. Therefore, the emphasis on pruritis aligns specifically with the complaint and the reaction expected from an injection.
