A nurse is educating a client about a new prescription for celecoxib.
Which of the following information should the nurse include in the teaching about the medication's mechanism of action?

Inhibits histamine response.

Inhibits COX-2.

Inhibits COX-1.

Inhibits beta receptors.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Celecoxib does not inhibit the histamine response. Histamine is involved in allergic reactions, and celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that targets specific enzymes involved in inflammation.

Choice B rationale

Celecoxib specifically inhibits COX-2, an enzyme involved in the inflammation pathway. This selective inhibition helps reduce inflammation and pain without significantly affecting COX-1, which is protective for the stomach lining.

Choice C rationale

COX-1 is not the primary target of celecoxib. Inhibition of COX-1 can lead to gastrointestinal side effects, which celecoxib aims to minimize by selectively inhibiting COX-2 instead.

Choice D rationale

Celecoxib does not inhibit beta receptors. Beta receptors are involved in cardiovascular responses, and beta blockers are used for conditions like hypertension, not inflammation.

Correct Answer is B

Explanation

Choice A rationale

Glucagon (GlucaGen) is not used for hyperglycemia. Hyperglycemia requires insulin or oral hypoglycemic agents to lower blood glucose levels.

Choice B rationale

Glucagon (GlucaGen) is used to treat hypoglycemia, especially in emergency situations when a person is unconscious or unable to consume oral glucose. It raises blood glucose levels by stimulating the liver to release stored glucose into the bloodstream.

Choice C rationale

Glucagon (GlucaGen) is not used for the treatment of type 2 diabetes mellitus. Management of type 2 diabetes typically includes lifestyle changes, oral hypoglycemic agents, and sometimes insulin therapy.

Choice D rationale

Glucagon (GlucaGen) is not used for diabetes insipidus. Diabetes insipidus is treated with medications such as desmopressin, which helps reduce urine output. .

A. Acts as an endogenous prostaglandin in the GI tract. B. Creates a protective barrier that adheres to an ulcer, which can stick to the ulcer for up to 6 hours. C. Neutralizes the acidity of the gastric acid. D. Antagonizes H2 receptors on parietal cells.

Correct Answer is B

Explanation

Choice B rationale

Sucralfate (Carafate) acts by forming a viscous, adhesive substance that binds to the ulcer site, creating a physical barrier protecting it from stomach acid and allowing healing.

Choice A rationale

Sucralfate does not function as an endogenous prostaglandin; it does not mimic or enhance prostaglandin activity in the GI tract.

Choice C rationale

Sucralfate does not neutralize gastric acid; that is the function of antacids.

Choice D rationale

Sucralfate does not antagonize H2 receptors on parietal cells; H2 receptor antagonists are a different class of medication.
