A nurse is caring for a client who is newly diagnosed with Parkinson's disease.
Which of the following medications should the nurse anticipate to administer to the client?

Choice A rationale

Insulin is used to manage blood glucose levels in clients with diabetes, including type 2 diabetes.

Choice B rationale

Metformin is an oral hypoglycemic agent used to treat type 2 diabetes by decreasing glucose production in the liver.

Choice C rationale

Glipizide is an oral medication used to stimulate insulin secretion from the pancreas in clients with type 2 diabetes.

Choice D rationale

Levothyroxine is a medication used to treat hypothyroidism and is not indicated for the treatment of type 2 diabetes. .

Choice A rationale

Antagonistic reactions occur when one drug interferes with the action of another, decreasing its effectiveness. This is not applicable in this case as aspirin and alcohol together increase the risk of bleeding rather than opposing each other's actions.

Choice B rationale

Synergistic reactions happen when two drugs enhance each other's effects. Aspirin and alcohol together can indeed increase the risk of gastrointestinal bleeding, but this is not referred to as a synergistic reaction.

Choice C rationale

Additive reactions occur when two drugs with similar effects add up to a greater effect. Aspirin and alcohol both increase the risk of bleeding, and their combined effect leads to gastrointestinal bleeding.

Choice D rationale

Neutral reactions imply that the drugs do not interact and have no combined effect, which is incorrect here as the combination of aspirin and alcohol leads to an increased risk of GI bleeding.
