Desmopressin

Diphenhydramine

Spironolactone

Answer and Explanation

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.

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.

A. Respiratory rate of 24/min B. Adventitious breath sounds C. Weight loss of 1.8 kg (4 lb) in the past 24 hours D. Elevation in blood pressure

Correct Answer is C

Explanation

Choice A reason: A respiratory rate of 24/min is slightly higher than the normal range (12-20 breaths per minute) and does not necessarily indicate the effectiveness of furosemide in treating pulmonary edema.

Choice B reason: Adventitious breath sounds, such as crackles or wheezes, are often present in pulmonary edema and would not indicate that the furosemide is effective. The resolution of these sounds would be a better indicator of improvement.

Choice C reason: Weight loss of 1.8 kg (4 lb) in the past 24 hours likely indicates a reduction in fluid retention, which is a desired effect of furosemide in the treatment of pulmonary edema. This diuretic effect reduces the fluid overload, thereby improving the symptoms of pulmonary edema.

Choice D reason: An elevation in blood pressure is not an expected outcome of effective furosemide therapy for pulmonary edema. Furosemide is a diuretic and would more likely lead to a reduction in blood pressure due to fluid loss.
