A nurse is caring for a client who has developed hives and urticaria following the administration of IV contrast dye after a cardiac catheterization. Which of the following medications should the nurse plan to administer?
Desmopressin
Diphenhydramine
Spironolactone
Metoclopramide
The Correct Answer is B
Choice A reason : Desmopressin is a medication used to treat conditions like diabetes insipidus and certain cases of hemophilia, not allergic reactions such as hives and urticaria.
Choice B reason: Diphenhydramine is an antihistamine that is commonly used to treat allergic reactions, including hives and urticaria. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.
Choice C reason: Spironolactone is a diuretic and is not used to treat allergic reactions. It is typically prescribed for conditions like heart failure, hypertension, and certain hormonal disorders.
Choice D reason: Metoclopramide is a medication used to treat nausea and gastroparesis, not allergic reactions.

Correct Answer is B
Explanation
Choice A reason : Administering corticosteroids is not the first-line action for dyspnea related to fluid overload or other causes of respiratory distress in this context.
Choice B reason : Slowing the infusion rate is appropriate when there are signs of fluid overload, such as dyspnea and hypertension. Contacting the provider is crucial for further assessment and management, which may include diuretics or other interventions.
Choice C reason : Lowering the head of the bed to semi-Fowler's may provide some relief for dyspnea, but it does not address the potential cause, which in this case could be fluid overload.
Choice D reason : Changing the infusion to lactated Ringer's would not be appropriate if the client is experiencing symptoms of fluid overload. The type of fluid is less important than the volume and rate of administration in this scenario.
Correct Answer is C
Explanation
Choice A reason: Administering aspirin is one of the first interventions for a client experiencing acute angina because aspirin has antiplatelet properties that help prevent blood clots, which can reduce the risk of a heart attack.
Choice B reason: Measuring blood pressure is important but not the first action to take. It provides valuable information about the cardiovascular status of the client and can influence further treatment decisions.
Choice C reason: Administering nitroglycerin is a priority action for acute angina as it helps to dilate the coronary arteries and relieve chest pain. However, it is typically administered after aspirin unless contraindicated.
Choice D reason: Initiating IV access is an important step in the management of acute angina, as it allows for the administration of medications and fluids if needed. However, it is not the first action to take during an acute angina episode.
