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.

Correct Answer is A

Explanation

Choice A Reason:Coronary artery bypass graft surgery (CABG) is not primarily performed to increase blood flow to the myocardium. Instead, it aims to restore blood flow to areas of the heart affected by blockages.

Choice B Reason:CABG does not intentionally decrease blood flow to the coronary arteries. On the contrary, it creates a new pathway to bypass blocked or partially blocked coronary arteries, improving blood flow to the heart muscle.

Choice C Reason:The primary purpose of CABG is to treat coronary artery disease by restoring blood flow to areas of the heart that aren't receiving enough blood. It involves using healthy blood vessels (usually from the chest or leg) to create a detour around blockages. By doing so, CABG improves heart function and reduces symptoms related to ischemia.

Choice D Reason:While CABG can indirectly prevent spasms of the coronary arteries by improving blood flow, it is not its primary purpose.

A. "I will take the Lasix in the morning." B. "I will drink lots of fluids with the Lasix." C. "I will count my radial pulse for one minute." D. "I will take it with each meal." E. "I will eat a banana daily."

Correct Answer is ["B","D"]

Explanation

Choice A reason: Taking Lasix in the morning is appropriate to avoid nocturia and sleep disturbances.

Choice B reason: Patients should be cautious with fluid intake when taking Lasix to avoid fluid overload, especially in heart failure.

Choice C reason: Counting the radial pulse is not directly related to Lasix administration but is a good practice for monitoring heart rate.

Choice D reason: Lasix should not be taken with each meal; it is usually taken once daily unless otherwise prescribed.

Choice E reason: Eating a banana daily is recommended to replenish potassium that may be lost due to the diuretic effect of Lasix.
