A client is newly prescribed with metformin (Glucophage) for type 2 diabetes.Which of the following statements indicate that the client understands the teaching of metformin?

Choice A rationale

Stopping the infusion immediately is crucial to prevent further exposure to the allergen causing the adverse reaction. This intervention halts the administration of gentamicin, which is likely causing the dyspnea, rash, and itchiness. Prompt discontinuation of the medication minimizes the severity of the allergic reaction and allows for further medical management.

Choice B rationale

Administering an IV fluid bolus to flush the medication is not the priority intervention in this case. While it might help to clear the medication from the bloodstream, it does not address the immediate need to stop the allergen exposure and manage the allergic reaction.

Choice C rationale

Encouraging the client to take deep breaths and remain calm is supportive, but it does not address the root cause of the allergic reaction, which is the administration of gentamicin. The immediate priority is to stop the infusion and then manage the symptoms.

Choice D rationale

Administering oxygen via nasal cannula may help alleviate respiratory distress, but it is not the priority intervention. The primary step is to stop the infusion to prevent further exposure to the allergen.

Choice A rationale

Excretion is a phase of pharmacokinetics where the drug or its metabolites are eliminated from the body, primarily via the kidneys.

Choice B rationale

Phlebitis is inflammation of a vein and is not a phase of pharmacokinetics. It is a medical condition rather than a pharmacokinetic process.

Choice C rationale

Distribution is a phase of pharmacokinetics where the drug is dispersed throughout the body’s tissues and fluids after absorption.

Choice D rationale

Absorption is a phase of pharmacokinetics where the drug is absorbed into the bloodstream from the site of administration.
