The healthcare provider (HCP) informs the licensed practical nurse/licensed vocational nurse (LPN/LVN) that the patient has cor pulmonale. The patient asks what this means. Which explanation by the nurse is most appropriate?

This means that both sides of your heart are weak and not pumping well.

This means that the left side of your heart is weak and failing.

This means that more testing is needed to determine what is wrong.

This means that the right side of your heart is weak and not pumping effectively.

Answer and Explanation

The Correct Answer is D

Choice A reason: Cor pulmonale specifically refers to right-sided heart failure. It occurs due to an underlying lung disorder causing pulmonary hypertension (high pressures in the lungs). The right ventricle enlarges and pumps blood less effectively.

Choice B reason:Cor pulmonale does not involve the left side of the heart. It is primarily related to the right ventricle.

Choice C reason: While further testing may be necessary, it does not directly explain cor pulmonale.

Choice D reason:Cor pulmonale results from lung conditions causing pulmonary hypertension.The right ventricle becomes enlarged and less effective due to increased pressure in the pulmonary arteries.
