When teaching a client about insulin therapy, the nurse should instruct the client to avoid which over-the- counter preparation that can interact with insulin?
Correct Answer: D
Rationale: Salicylates, such as aspirin, can potentiate the hypoglycemic effects of insulin. They can increase insulin sensitivity and potentially lead to low blood sugar levels (hypoglycemia). Therefore, clients using insulin should avoid over-the-counter salicylate preparations to prevent this interaction and the risk of hypoglycemia. It is important for clients to always consult healthcare professionals before taking any new medications or over-the-counter preparations when using insulin therapy.
