A nurse is collecting data on a client who has mitral valve stenosis. Which of the following findings should the nurse expect?
Barrel chest
Bradycardia
Clubbing of the fingers
Heart murmur
The Correct Answer is D
A. Barrel chest. A barrel chest is commonly seen in chronic obstructive pulmonary disease (COPD) rather than mitral valve stenosis.
B. Bradycardia. Bradycardia is not typically associated with mitral valve stenosis, as symptoms often include rapid or irregular heartbeat.
C. Clubbing of the fingers. Clubbing is associated with chronic hypoxia, often due to pulmonary conditions, not specifically with mitral valve stenosis.
D. Heart murmur. Mitral valve stenosis causes turbulent blood flow through the narrowed valve, resulting in a characteristic murmur.

Correct Answer is B
Explanation
A. "Your heart condition is caused from stiffening of the walls of the ventricles." Stiffening of the ventricular walls describes restrictive cardiomyopathy, not DCM.
B. "Your heart condition is caused by excessive stretching of the ventricles." DCM involves excessive stretching and thinning of the ventricular walls, leading to impaired contraction.
C. "Your heart condition is caused when the ventricular tissue becomes fibrous and fatty." This describes arrhythmogenic right ventricular dysplasia, not DCM.
D. "Your heart condition is caused by thickening of the ventricular walls and septum." This describes hypertrophic cardiomyopathy, not DCM.
Correct Answer is D
Explanation
A. Depression: While propranolol can sometimes worsen symptoms of depression, this is not as critical as the impact on conditions like heart failure.
B. Glaucoma: Propranolol does not typically affect glaucoma; however, some beta-blockers are used to treat glaucoma.
C. Migraine: Propranolol is sometimes used to prevent migraines, so a history of migraines would not require discontinuation.
D. Heart failure: Propranolol can exacerbate heart failure by reducing myocardial contractility. Clients with heart failure require careful monitoring or an alternative medication.
