What is the primary cause of endocarditis?

  1. Viral infection

  2. Bacterial infection

  3. Fungal infection

  4. Parasitic infection


Correct Option: B
Explanation:

Endocarditis is predominantly caused by bacterial infections, particularly those caused by Staphylococcus aureus and Streptococcus species.

Which heart valve is most commonly affected by endocarditis?

  1. Mitral valve

  2. Aortic valve

  3. Pulmonary valve

  4. Tricuspid valve


Correct Option: A
Explanation:

The mitral valve, which separates the left atrium from the left ventricle, is the most frequently affected valve in endocarditis.

What is the most common symptom of endocarditis?

  1. Chest pain

  2. Shortness of breath

  3. Fever

  4. Fatigue


Correct Option: C
Explanation:

Fever is the most prevalent symptom of endocarditis, often accompanied by chills and night sweats.

Which diagnostic test is commonly used to confirm endocarditis?

  1. Echocardiogram

  2. Electrocardiogram (ECG)

  3. Chest X-ray

  4. Blood culture


Correct Option: A
Explanation:

Echocardiogram, a non-invasive imaging technique, is commonly employed to visualize the heart valves and detect any abnormalities associated with endocarditis.

What is the primary treatment for endocarditis?

  1. Antibiotics

  2. Surgery

  3. Heart transplant

  4. Radiation therapy


Correct Option: A
Explanation:

Antibiotics are the mainstay of treatment for endocarditis, aiming to eliminate the underlying bacterial infection.

Which antibiotic is commonly used to treat endocarditis caused by Staphylococcus aureus?

  1. Penicillin

  2. Vancomycin

  3. Gentamicin

  4. Erythromycin


Correct Option: B
Explanation:

Vancomycin is frequently used to treat endocarditis caused by Staphylococcus aureus, particularly in cases of methicillin-resistant Staphylococcus aureus (MRSA) infections.

What is the recommended duration of antibiotic therapy for endocarditis?

  1. 2 weeks

  2. 4 weeks

  3. 6 weeks

  4. 8 weeks


Correct Option: C
Explanation:

The standard duration of antibiotic therapy for endocarditis is typically 6 weeks, although it may vary depending on the severity of the infection and the patient's response to treatment.

When is surgery necessary in the treatment of endocarditis?

  1. To repair or replace damaged heart valves

  2. To remove infected vegetations

  3. To prevent heart failure

  4. To improve blood flow to the heart


Correct Option: A
Explanation:

Surgery may be required in cases of severe endocarditis to repair or replace damaged heart valves, prevent heart failure, and improve blood flow to the heart.

Which patient population is at increased risk of developing endocarditis?

  1. Individuals with congenital heart defects

  2. Patients with prosthetic heart valves

  3. People with weakened immune systems

  4. All of the above


Correct Option: D
Explanation:

Individuals with congenital heart defects, patients with prosthetic heart valves, and people with weakened immune systems are all at increased risk of developing endocarditis.

What is the most effective way to prevent endocarditis?

  1. Good oral hygiene

  2. Proper wound care

  3. Avoiding intravenous drug use

  4. All of the above


Correct Option: D
Explanation:

Maintaining good oral hygiene, practicing proper wound care, and avoiding intravenous drug use are all essential preventive measures against endocarditis.

Which type of endocarditis is caused by fungi?

  1. Infective endocarditis

  2. Non-infective endocarditis

  3. Marantic endocarditis

  4. Libman-Sacks endocarditis


Correct Option: C
Explanation:

Marantic endocarditis is a rare form of endocarditis caused by fungal infections, typically occurring in individuals with weakened immune systems or severe underlying medical conditions.

What is the most common complication of endocarditis?

  1. Heart failure

  2. Stroke

  3. Kidney failure

  4. Sepsis


Correct Option: A
Explanation:

Heart failure is the most frequent complication of endocarditis, resulting from damage to the heart valves and impaired heart function.

Which laboratory test is commonly used to monitor the response to antibiotic therapy in endocarditis?

  1. C-reactive protein (CRP)

  2. Erythrocyte sedimentation rate (ESR)

  3. Blood culture

  4. All of the above


Correct Option: D
Explanation:

C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and blood culture are all laboratory tests used to monitor the response to antibiotic therapy in endocarditis.

What is the prognosis of endocarditis if left untreated?

  1. Complete recovery

  2. Long-term complications

  3. Death

  4. All of the above


Correct Option: C
Explanation:

If left untreated, endocarditis can lead to severe complications, including heart failure, stroke, and death.

Which medical specialty is primarily responsible for the diagnosis and management of endocarditis?

  1. Cardiology

  2. Infectious disease

  3. Cardiothoracic surgery

  4. All of the above


Correct Option: D
Explanation:

Endocarditis is typically managed by a multidisciplinary team involving cardiologists, infectious disease specialists, and cardiothoracic surgeons.
