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 A

Explanation

A. Troponin T: Troponin T remains elevated for 10 to 14 days after a myocardial infarction. This protein is highly specific for cardiac muscle injury and is used to confirm myocardial infarction.

B. Creatinine phosphokinase: Creatinine phosphokinase (CPK) typically returns to normal levels within 3 days after a myocardial infarction, so it would no longer be elevated at this point.

C. Myoglobin: Myoglobin rises early after a myocardial infarction but is not specific to heart muscle and returns to normal within 24 hours, so it would not be elevated at this time.

D. Creatinine kinase-MB: Creatinine kinase-MB (CK-MB) usually returns to normal levels within 2 to 3 days after a myocardial infarction, so it is unlikely to still be elevated 6 days later.

Correct Answer is ["120"]

Explanation

Flow rate (gtt/min) =(Volume ×Drop factor)/60 = (120 ×60)/60

Flow rate (gtt/min)= 120 gtt/min
