A patient has been diagnosed with Group A Streptococcal pharyngitis. The nurse recognizes the need for antibiotic therapy to help prevent the development of which serious condition

A. A 4 cm aneurysm in a young patient, especially one as young as 28 years old, would typically be monitored more closely rather than immediately undergoing surgery. Surgical intervention is more commonly considered for larger aneurysms or in cases where there are other risk factors or symptoms present.
B. Marfan's syndrome is a genetic disorder that affects connective tissue and is associated with a higher risk of developing aortic aneurysms, including abdominal aortic aneurysms. Patients with Marfan's syndrome are at a greater risk of aneurysm growth and rupture due to the weakened connective tissue.
C. Hypertension is a significant risk factor for the growth and rupture of an AAA. While managing hypertension with beta-blockers is important in controlling the risk, the presence of hypertension alone does not necessarily indicate that surgical intervention is immediately necessary

D. While patient concerns and anxiety about their condition are valid and important, expressing concern about dying does not directly determine the need for surgical intervention. Surgical decisions are based on objective clinical criteria, such as the size of the aneurysm, growth rate, symptoms, and overall health of the patient.

A. Continuous antibiotic therapy is not typically recommended for preventing recurrence of endocarditis. Instead, endocarditis prophylaxis involves administering antibiotics only before certain invasive procedures that have a risk of introducing bacteria into the bloodstream.
B. Taking aspirin is not a recommended strategy for preventing endocarditis or vegetative lesions on heart valves. The formation of vegetative lesions in endocarditis is related to the presence of infection and not typically prevented by aspirin.
C. This is the correct recommendation for preventing recurrence of endocarditis. Prophylactic antibiotics are recommended before certain invasive procedures, such as dental work or surgery, to prevent bacteria from entering the bloodstream and causing endocarditis. This is especially important for patients with prosthetic heart valves, a history of endocarditis, or certain congenital heart defects.
D. Starting antibiotic therapy based on exposure to persons with infections is not a standard or effective strategy for preventing endocarditis. The focus of endocarditis prevention is on specific prophylaxis before high-risk procedures rather than general antibiotic use based on exposure to infected individuals.
