A nurse started a client's gentamicin via an intravenous (IV) route that is programmed to infuse over one hour.
Ten minutes after the administration, the client reports dyspnea, generalized rash, and itchiness.
What is the priority intervention for this client?
Stop the infusion immediately.
Administer an IV fluid bolus to flush the medication.
Encourage the client to take deep breaths and remain calm.
Administer oxygen via nasal cannula.
The Correct Answer is A
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.

Correct Answer is B
Explanation
Choice A rationale
This statement is incorrect because an antagonist medication changes the effects of normal cellular functions by blocking receptors.
Choice B rationale
An antagonist medication binds to receptors and blocks the usual receptor activity, preventing the normal action of the endogenous substance.
Choice C rationale
This statement describes an agonist medication, which binds to receptors and increases the effects of normal cellular functions.
Choice D rationale
This statement is incorrect because an antagonist medication does not both increase and decrease the effects on normal cellular functions; it primarily blocks receptor activity.
Correct Answer is B
Explanation
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.
