A nurse in a provider's office is collecting data from a client who reports dyspnea and fatigue. The nurse determines that the client also has tachycardia and edema. Which of the following disorders should the nurse suspect?

A. Heart failure: The combination of exertional dyspnea, fatigue, tachycardia and peripheral edema is classic for heart failure (reduced cardiac output and fluid retention). B. Aortic stenosis: May cause dyspnea and syncope but peripheral edema is less prominent early; constellation fits HF better. C. Asthma: Causes dyspnea and wheeze but not peripheral edema or systemic tachycardia as a primary finding. D. Aortic valve regurgitation: Causes volume overload and dyspnea over time but the generalized picture with edema is most consistent with heart failure.
