1. Client with left ventricular heart failure
2. Client experiencing a massive pulmonary embolism
3. Client with chronic obstructive pulmonary disease (COPD)

Rationale: Cor pulmonale is an alteration in the structure and function of the right ventricle caused by a primary disorder of the respiratory system or a blood disorder. Primary disorders of the respiratory system include pulmonary embolism, interstitial lung disease, COPD, and primary pulmonary hypertension. Blood disorders leading to cor pulmonale include polycythemia vera, sickle cell disease, and macrohemoglobinemia. Right ventricular disease caused by a primary abnormality of the left ventricle is not considered cor pulmonale.
