Extract:
Question 1 of 5
What effect does valvular regurgitation have on a patient?
Correct Answer: B
Rationale: Valvular regurgitation causes backward blood flow, leading to volume overload in the prior chamber. Fever, autoimmune reactions, and vessel narrowing are not direct effects.
Question 2 of 5
The patient with acute pericarditis is having a pericardiocentesis. What complication should the nurse monitor the patient for?
Correct Answer: C
Rationale: Pneumothorax is a significant risk during pericardiocentesis if the needle punctures the lung. Pneumonia, myocardial infarction, and CVA are less likely complications.
Question 3 of 5
A patient has been diagnosed with a 4cm abdominal aortic aneurysm. Which of the following conditions would indicate surgical intervention may be necessary?
Correct Answer: B
Rationale: Marfan's syndrome increases AAA rupture risk due to weakened connective tissue, often necessitating surgery. Young age, controlled hypertension, or patient concerns do not directly indicate surgery.
Question 4 of 5
A nurse is teaching several newly licensed nurses about cardiac valve replacement. Which of the following should the nurse include in the teaching?
Correct Answer: A
Rationale: Among the four heart valves (aortic, mitral, tricuspid, and pulmonary), the aortic and mitral valves are indeed the most commonly replaced valves. Aortic stenosis and mitral valve regurgitation are frequent indications for valve replacement. Aortic stenosis primarily affects the left ventricle, not the right. Mitral valve insufficiency primarily causes problems on the left side of the heart. The tricuspid valve is on the right side of the heart and its inadequate closure affects the right side, not the left ventricle.
Question 5 of 5
The nurse is obtaining a health history from a 24-year-old patient with hypertrophic cardiomyopathy. Which information obtained by the nurse is most important in planning care?
Correct Answer: C
Rationale: A family history of sudden cardiac death indicates a high risk for similar outcomes in hypertrophic cardiomyopathy, critical for care planning. Infections, CAD, and past cocaine use are less directly relevant.
