The nurse is assessing a client with a diagnosis of mitral valve stenosis. Which element of assessment data indicates that the disease is worsening?

Increase in systolic blood pressure 10 mmHg above client's norm

reports dyspnea after walking up 2 flights of stairs

Jugular vein distention and +3 peripheral edema

Complaints of epigastric pain after eating a large meal

Answer and Explanation

The Correct Answer is C

A. Increase in systolic blood pressure 10 mmHg above client's norm: A mild increase in systolic blood pressure is not a specific indicator of mitral stenosis progression. Blood pressure fluctuations may occur due to various factors and are not typically used as a primary marker of worsening valve disease.

B. reports dyspnea after walking up 2 flights of stairs: Exertional dyspnea is a common early symptom of mitral stenosis due to reduced left atrial emptying and pulmonary congestion. However, this does not necessarily indicate worsening unless the symptom becomes more severe or occurs with minimal exertion.

C. Jugular vein distention and +3 peripheral edema: These are signs of right-sided heart failure, which may result from long-standing mitral stenosis leading to pulmonary hypertension and subsequent right ventricular hypertrophy and failure. This indicates disease progression and worsening cardiac function.

D. Complaints of epigastric pain after eating a large meal: Epigastric discomfort is not a typical symptom of mitral stenosis and is more likely related to gastrointestinal issues. It does not reflect the status or progression of the cardiac condition.

Correct Answer is C

Explanation

A. Administer amiodarone 200 mg IV push: Amiodarone is used for shockable rhythms like ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) that are refractory to defibrillation. The rhythm on the monitor is asystole, which is non-shockable, and amiodarone is not indicated here.

B. Defibrillate the client using 200 joules: Defibrillation is only appropriate for shockable rhythms such as VF or pulseless VT. Asystole is not shockable, and defibrillation in this rhythm would be ineffective and inappropriate.

C. CPR until the physician stops the code: The rhythm strip shows asystole, a flatline with no electrical activity. The priority intervention is to initiate and continue high-quality cardiopulmonary resuscitation (CPR) immediately and continue until the code is terminated by the physician. This is consistent with Advanced Cardiac Life Support (ACLS) guidelines.

D. Administer adenosine 12 mg IV push: Adenosine is used to terminate supraventricular tachycardia (SVT) and is not indicated in asystole or during cardiac arrest. It would have no effect in a rhythm with no electrical activity.

A. "All patients with this disorder have a genetic defect which causes it." B. "There are many theories about its development but amyloidosis in your history is a probable cause." C. "You probably had a silent heart attack which caused this disorder." D. "Your long-standing hypertension caused this disorder."

Correct Answer is B

Explanation

A. "All patients with this disorder have a genetic defect which causes it.": Restrictive cardiomyopathy is not primarily a genetic disorder. While there may be rare familial forms, most cases are acquired, often secondary to systemic diseases, making this statement inaccurate and misleading.

B. "There are many theories about its development but amyloidosis in your history is a probable cause.": This is the most accurate response. Restrictive cardiomyopathy is commonly associated with infiltrative diseases such as amyloidosis, hemochromatosis, and sarcoidosis, which impair ventricular filling due to stiff, non-compliant myocardium.

C. "You probably had a silent heart attack which caused this disorder.": Silent myocardial infarctions can contribute to ischemic cardiomyopathy, typically leading to dilated, not restrictive, changes in the myocardium. They are not a primary cause of restrictive cardiomyopathy.

D. "Your long-standing hypertension caused this disorder.": Chronic hypertension more commonly leads to left ventricular hypertrophy and may contribute to diastolic heart failure, but it is not a typical cause of restrictive cardiomyopathy.
