A nurse is caring for a client who has developed cor pulmonale secondary to an acute exacerbation of chronic obstructive pulmonary disease (COPD). Which of the following manifestations is caused by corpulmonale?
Barrel chest
Clubbing of the fingers
Destruction of the alveoli
Peripheral edema
The Correct Answer is D
A. Barrel chest is a physical finding commonly associated with COPD due to hyperinflation of the lungs. It results from chronic air trapping and enlargement of the chest. While barrel chest is not directly caused by cor pulmonale, it is a characteristic feature of advanced COPD.
B. Clubbing of the fingers is not directly caused by cor pulmonale. It is typically associated with chronic hypoxia, which can occur in advanced lung diseases like COPD. Clubbing involves changes in the shape and texture of the nails and fingertips due to chronic lack of oxygen in the blood.
C. Destruction of the alveoli is a hallmark of emphysema, which is a type of COPD. Emphysema leads to loss of lung tissue elasticity and surface area, contributing to chronic airflow limitation. While emphysema is a risk factor for developing cor pulmonale, destruction of alveoli itself does not directly cause cor pulmonale.
D. Peripheral edema is a manifestation caused by cor pulmonale. When the right side of the heart fails (cor pulmonale), it leads to increased pressure in the pulmonary circulation, which can eventually cause fluid to leak out into the tissues, resulting in peripheral edema. This is a consequence of the right heart's inability to effectively pump blood forward due to pulmonary hypertension and subsequent right ventricular failure.

Correct Answer is D
Explanation
A. This option describes a phenomenon seen in heparin-induced thrombocytopenia (HIT), not in immune thrombocytopenic purpura (ITP). In HIT, antibodies against the PF4-heparin complex can cause platelet activation and aggregation, leading to thrombocytopenia. However, this is not characteristic of ITP.
B. Abnormally long von Willebrand factor is seen in von Willebrand disease (VWD), not in ITP. VWD is a bleeding disorder caused by deficiency or dysfunction of von Willebrand factor, which plays a key role in platelet adhesion and aggregation. It is not typically associated with ITP.
C. ADAMTS13 deficiency is characteristic of thrombotic thrombocytopenic purpura (TTP), not ITP. TTP is a rare blood disorder where small blood clots form in blood vessels throughout the body, leading to thrombocytopenia (low platelet count) and other complications. It is distinct from ITP.
D. In immune thrombocytopenic purpura (ITP), the immune system mistakenly attacks and destroys platelets, leading to a low platelet count. Antibodies, particularly anti-platelet antibodies such as anti-GP IIb/IIIa or anti-GP Ib/IX, coat the surface of platelets. These antibody-coated platelets are recognized and destroyed by macrophages in the spleen and liver, contributing to thrombocytopenia.
Correct Answer is B
Explanation
A. Fluticasone is a corticosteroid inhaler used for maintenance therapy to reduce inflammation in the airways over time. It is not a rescue medication for acute symptoms. Clients with COPD should use short-acting bronchodilators (such as albuterol) as their first-line treatment for relieving acute symptoms like shortness of breath or wheezing.
B. This statement is correct. Fluticasone is a corticosteroid medication that, when inhaled, can increase the risk of developing oral candidiasis (thrush). Clients should be instructed to rinse their mouth with water and spit after using the inhaler to minimize this risk. Inspecting the mouth daily for signs of white patches, soreness, or difficulty swallowing is important. If thrush develops, clients may need antifungal treatment.
C. This statement is not necessary for fluticasone inhaler use. Fluticasone is not known to significantly affect heart rate. Monitoring heart rate before each dose is more relevant for medications that can cause changes in heart rate, such as bronchodilators (e.g., beta-agonists). However, clients should monitor for symptoms like palpitations or rapid heart rate and report them to their healthcare provider.
D. Fluticasone is a maintenance medication that should be taken regularly as prescribed, regardless of symptoms. Skipping doses can lead to worsening of COPD symptoms and exacerbations. Clients should adhere to the prescribed dosing schedule to achieve optimal control of their condition.
