A patient newly admitted with pulmonary edema is due to receive several medications. Which medication should the nurse efore administration?

Choice A rationale
Education on the necessity of continuous antibiotic prophylaxis is crucial for patients who have just recovered from rheumatic fever. Rheumatic fever is an inflammatory disease that can develop as a complication of untreated or inadequately treated strep throat or scarlet fever.
Patients who have had rheumatic fever are at risk of getting it again if they have another strep infection. Continuous antibiotic prophylaxis can prevent recurrent infections and the development of rheumatic heart disease.
Choice B rationale
While anticoagulation therapy may be necessary for some patients with heart conditions, it is not typically the most important nursing action for a patient who has just recovered from rheumatic fever. Rheumatic fever can cause inflammation and damage to the heart valves, but it does not typically cause blood clots, which are the primary reason for anticoagulation therapy.
Choice C rationale
Adherence to standard infection control procedures is important for all patients, but it is not the most important nursing action for a patient who has just recovered from rheumatic fever. The primary concern for these patients is preventing recurrent strep infections, which can be achieved through continuous antibiotic prophylaxis.
Choice D rationale
While physical activity management may be part of the overall care plan for a patient who has just recovered from rheumatic fever, it is not typically the most important nursing action. The primary concern for these patients is preventing recurrent strep infections, which can be achieved through continuous antibiotic prophylaxis.

Choice A rationale
Left heart failure is a common cause of right heart failure. When the left side of the heart is unable to pump blood efficiently, it can cause increased pressure in the lungs, which can then lead to right heart failure.
Choice B rationale
Pericarditis, an inflammation of the sac-like covering around the heart, is not typically a direct cause of right heart failure.
Choice C rationale
While hypertension, or high blood pressure, can contribute to heart failure, it typically affects the left side of the heart more than the right.
Choice D rationale
Acute pneumonia, an infection that inflames the air sacs in one or both lungs, is not typically a direct cause of right heart failure.
