The nurse is preparing to administer warfarin to a client with a mechanical valve replacement. The client's international normalized ratio is 2.7. What action will the nurse take?

Administer the medication as ordered.

A nurse is caring for a client receiving warfarin therapy following a mechanical valve replacement. The client had a prothrombin time and International Normalized Ratio (INR) drawn before breakfast. The laboratory report shows the client's INR reading was 4. What is the nurse's first priority ?

Assess the client for bleeding and notify the health care provider of the results.

The nurse is auscultating the heart sounds of a patient with mitral stenosis. The pulse rhythm is weak and irregular. What rhythm does the nurse expect to see on the electrocardiogram (ECG)?

Atrial fibrillation

The nurse is caring for a client diagnosed with bacterial myocarditis. The client's heart rate is 120-130 beats per minute and blood pressure 158/89 mm Hg. What medications will the nurse administer to treat the client with myocarditis? Select all that apply.

carvedilol amiodarone penicillin

A nurse is caring for a client who had an aortic balloon valvuloplasty. The nurse should inspect the surgical insertion site closely for which complication(s)?

Bleeding and infection

Which nursing intervention should a nurse perform when a client with cardiomyopathy receives a diuretic?

Check regularly for dependent edema

A nurse evaluates a client and suspects pericarditis. What indicator is considered the most characteristic symptom of pericarditis?

A client with a recent myocardial infarction was admitted to the hospital with a new diagnosis of mitral valve regurgitation. Which assessment data obtained by the nurse should be immediately communicated to the health care provider?

Crackles audible throughout the lungs

A client is admitted to the hospital with aortic stenosis. What assessment findings would indicate the development of left ventricular failure?

Dyspnea, orthopnea, pulmonary edema

A client reporting heart palpitations is diagnosed with atrial fibrillation caused by mitral valve prolapse. To relieve the symptoms, the nurse should teach the client which dietary intervention?

Eliminate caffeine and alcohol

A client is diagnosed with rheumatic endocarditis. What bacterium is the nurse aware causes this inflammatory response?

Group A, beta-hemolytic streptococcus

Which type of graft is used when a heart valve replacement is made of tissue from an animal heart valve?

Heterograft

The client underwent an appendectomy 20 years earlier and an aortic valve replacement 2 years before this admission. What history finding is a major risk factor for infective endocarditis?

History of aortic valve replacement

A client with endocarditis is being discharged home. What statement indicates effectiveness of client teaching about preventing recurrence of the infection?

I will ask for antibiotics whenever I have dental work done."

The nurse suspects a client has developed pericarditis after a week of cold-like symptoms. Which of the client's signs and symptoms indicate pericarditis?

A nurse reviewing a client's echocardiogram report reads the following statements: "The heart muscle is asymmetrically thickened and the overall size and mass are increased, especially along the septum. The ventricular walls are thickened, reducing the size of the ventricular cavities. Several areas of the myocardium show evidence of scarring." The nurse knows these manifestations are indicative of which type of cardiomyopathy?

hypertrophic

A nurse is teaching a client about mitral stenosis. What is the key teaching point regarding the disruption to the normal flow of blood through the heart due to mitral stenosis?
