A nurse is collecting data from a client who has mitral stenosis. Which of the following findings is a manifestation of this condition?

S3 heart sound

Dyspnea on exertion

Cyanosis

S4 Heart Sound

Answer and Explanation

The Correct Answer is B

A. S3 heart sound: An S3 heart sound is often associated with heart failure and volume overload, not specifically mitral stenosis.

B. Dyspnea on exertion: Dyspnea on exertion is a classic symptom of mitral stenosis. The narrowing of the mitral valve restricts blood flow from the left atrium to the left ventricle, causing pulmonary congestion and shortness of breath, especially during physical activity.

C. Cyanosis: While cyanosis can occur in advanced stages of heart disease, it is not a primary symptom of mitral stenosis. It indicates severe oxygenation issues, which are usually late findings.

D. S4 heart sound: An S4 heart sound is typically associated with left ventricular hypertrophy, which can occur in advanced cases of mitral stenosis. However, it's not a specific early manifestation of the condition.

Correct Answer is C

Explanation

A. The QT interval is equal to the R to R interval. This is not a finding associated with myocardial infarction. QT interval changes are more related to electrolyte imbalances or medication effects.

B. The QRS intervals are 0.08 second. A QRS duration of 0.08 seconds is normal and does not indicate myocardial infarction. Prolongation of the QRS complex might suggest a bundle branch block or other conduction issues.

C. The ST segment is above the isoelectric line. ST-segment elevation is a hallmark sign of an acute myocardial infarction (STEMI). It reflects injury to the heart muscle.

D. The PR intervals are 0.15 second. A PR interval of 0.15 seconds is within the normal range (0.12–0.20 seconds) and does not indicate myocardial infarction.

A. "You will be prescribed medication that will keep you well for years to come." B. "Do you have family members who died from heart disease?" C. "You should discuss these worries with your physician." D. "Tell me more about these fears."

Correct Answer is D

Explanation

A. "You will be prescribed medication that will keep you well for years to come." This response provides false reassurance. Although medications can help manage angina, it does not guarantee that the client will not experience future complications.

B. "Do you have family members who died from heart disease?" This question may not address the client's immediate emotional needs and could come off as dismissive of the client's fear.

C. "You should discuss these worries with your physician." This statement redirects the client's concerns to the physician rather than addressing the client's emotional needs and fears in the moment.

D. "Tell me more about these fears." This response is therapeutic and encourages the client to express his concerns and feelings, which is a key part of addressing fear and anxiety.
