Which disorder would the nurse recognize as the likely cause of right heart failure (cor pulmonale)?

Upper GI bleeding

Chronic obstructive pulmonary disease (COPD)

Liver failure

Renal failure

Answer and Explanation

The Correct Answer is B

Choice A reason: Upper GI bleeding is not a direct cause of right heart failure (cor pulmonale). While severe GI bleeding can lead to other complications such as anemia or shock, it does not typically result in cor pulmonale.

Choice B reason: Chronic obstructive pulmonary disease (COPD) is a primary cause of cor pulmonale. COPD leads to chronic hypoxia, which increases pressure in the pulmonary arteries (pulmonary hypertension). The right ventricle of the heart must work harder to pump blood through these high-pressure arteries, eventually leading to right heart failure.

Choice C reason: Liver failure can lead to various systemic complications such as fluid imbalance and electrolyte disturbances, but it is not a direct cause of right heart failure (cor pulmonale). Cor pulmonale is specifically related to pulmonary conditions that increase right ventricular workload.

Choice D reason: Renal failure, while serious and capable of causing cardiovascular complications due to fluid overload and hypertension, is not typically linked to the development of cor pulmonale. The primary cause of cor pulmonale is chronic lung disease like COPD, which directly affects the pulmonary vasculature.

Correct Answer is D

Explanation

Choice A reason: Cantaloupe and cottage cheese are not particularly high in iron. While cantaloupe provides vitamin C, which can enhance iron absorption, the overall iron content of this meal is low, making it less effective for treating iron-deficiency anemia.

Choice B reason: Cornmeal muffin and orange juice offer some nutrients, including vitamin C from orange juice, which helps with iron absorption. However, cornmeal muffins do not provide significant iron content, making this choice suboptimal for iron-deficiency anemia.

Choice C reason: Strawberry and banana fruit plate provides vitamins and minerals, including vitamin C from strawberries, but it lacks substantial iron content. This choice is not adequate for addressing iron-deficiency anemia.

Choice D reason: Omelet and whole wheat toast are excellent choices for increasing dietary iron intake. Eggs in the omelet provide heme iron, which is easily absorbed by the body, and whole wheat toast contains non-heme iron. Combined, they offer a balanced and effective meal for managing iron-deficiency anemia.

A. Idiopathic pulmonary fibrosis B. Sarcoidosis C. Atelectasis D. Pulmonary embolus (PE)

Correct Answer is D

Explanation

Choice A reason: Idiopathic pulmonary fibrosis is a chronic, progressive lung disease characterized by scarring of the lung tissue. Tissue plasminogen activators (tPAs) are not used for this condition, as they are primarily designed to dissolve blood clots, not to address fibrotic changes in the lungs.

Choice B reason: Sarcoidosis is an inflammatory disease that affects multiple organs, particularly the lungs and lymph glands. It involves the growth of tiny collections of inflammatory cells called granulomas. Tissue plasminogen activators are not used in the treatment of sarcoidosis since the condition is not related to blood clots but rather to immune system dysregulation.

Choice C reason: Atelectasis is the complete or partial collapse of a lung or lobe of a lung due to alveoli deflation. The treatment typically focuses on re-expanding the lung tissue through techniques such as deep breathing exercises, bronchoscopy, or mechanical ventilation. Tissue plasminogen activators are not relevant for this condition, as they are used to dissolve blood clots, not to treat lung collapse.

Choice D reason: Pulmonary embolus (PE) is a blockage in one of the pulmonary arteries in the lungs, usually caused by blood clots that travel to the lungs from the legs or other parts of the body (deep vein thrombosis). Tissue plasminogen activators are used to treat PE because they can effectively dissolve the blood clots obstructing the pulmonary arteries, thereby restoring normal blood flow and preventing further complications.
