A 35-year-old patient presents with pulmonary hypertension and is diagnosed with right heart failure. What is the most likely cause of this condition?

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
While assessing the gag reflex is important in certain situations, such as after surgery involving anesthesia, it is not typically a crucial assessment following Percutaneous Transluminal Angioplasty (PTA) of the lower extremity.
Choice B rationale
Checking for dye allergies is important before a procedure that uses contrast dye. However, it is not a crucial post-procedure assessment.
Choice C rationale
Monitoring of pedal pulses is crucial following PTA of the lower extremity. This is because the procedure involves the arteries in the legs, and monitoring pedal pulses can help assess blood flow to the area and detect potential complications such as occlusion or clot formation.
Choice D rationale
While the Ankle-Brachial Index can be used to diagnose Peripheral Arterial Disease (PAD), it is not typically a crucial assessment immediately following PTA3.
