A nurse is teaching a client about foods and beverages that can cause diarrhea.Which of the following should the nurse include in the teaching?

Choice A rationale

Returning the opened medication to the medication cart is inappropriate because once a medication is opened and refused by a client, it must be disposed of properly. This action helps maintain safety and prevents contamination.

Choice B rationale

Reporting the incident to the provider is not necessary in this context as the refusal to take medication can be managed by the nurse by following the facility's protocol.

Choice C rationale

Filling out an incident report is required because the client's refusal to take the medication is considered a significant event. Incident reports are used to document and analyze such events to improve patient care and safety.

Choice D rationale

Notifying the facility's ethics committee is unnecessary for a medication refusal incident, as it does not involve an ethical dilemma requiring their intervention.

Choice A rationale

Toxic levels refer to concentrations of a medication that are high enough to cause harmful effects or poisoning. This is not related to the lowest serum concentration.

Choice B rationale

Peak levels are the highest concentration of a medication in the bloodstream after administration. This occurs after the drug is absorbed and distributed.

Choice C rationale

Trough levels occur when the medication is at its lowest concentration in the bloodstream, typically just before the next dose is due. Monitoring trough levels helps ensure therapeutic effectiveness while avoiding toxicity.

Choice D rationale

Half-life refers to the time it takes for the concentration of a drug in the bloodstream to decrease by half. It is not directly related to the lowest serum concentration at a specific point in time.
