What is an indication for apixaban?
Treatment for acute myocardial infarction
Prevention of pulmonary embolism
Treatment for chronic hypertension
Prevention of renal failure
The Correct Answer is B
A. Treatment for acute myocardial infarction: Apixaban is an oral anticoagulant used to prevent clot formation. It is not indicated as a primary treatment for acute myocardial infarction, although it may be used in certain patients with atrial fibrillation or thromboembolic risk.
B. Prevention of pulmonary embolism: Apixaban is indicated for the prevention and treatment of venous thromboembolism, including deep vein thrombosis and pulmonary embolism. It inhibits factor Xa, reducing the formation of blood clots in high-risk patients.
C. Treatment for chronic hypertension: Apixaban does not lower blood pressure and is not used to treat hypertension. Its anticoagulant effect targets clotting pathways rather than vascular resistance.
D. Prevention of renal failure: Apixaban has no direct effect on kidney function and is not used to prevent renal failure. Its role is limited to anticoagulation and reducing thromboembolic events.

Correct Answer is A
Explanation
A. Increases cardiac output: Dobutamine is a beta-1 adrenergic agonist that primarily increases the strength of myocardial contractions, leading to enhanced cardiac output. It is commonly used in clients with heart failure or cardiogenic shock to improve tissue perfusion without significantly increasing heart rate.
B. Promotes diuresis: Dobutamine does not have a direct diuretic effect. While improved cardiac output may indirectly enhance renal perfusion and urine output, promoting diuresis is not its primary therapeutic action.
C. Increases blood pressure: Dobutamine may slightly increase systolic blood pressure due to improved cardiac output, but it is not primarily used as an antihypotensive agent. Its main role is enhancing myocardial contractility rather than raising blood pressure.
D. Inhibits platelet aggregation: Dobutamine has no effect on platelet function or aggregation. Its mechanism of action is limited to stimulating beta-1 receptors in the heart to improve contractility.
Correct Answer is B
Explanation
A. Chicken breast: Chicken breast is low in vitamin K and does not significantly affect warfarin’s anticoagulant effect. Regular consumption does not require adjustment in warfarin dosing, so it is generally safe to eat without major concern.
B. Brussels sprouts: Brussels sprouts are high in vitamin K, which can interfere with warfarin’s effectiveness by promoting clotting. Sudden increases or decreases in intake can cause fluctuations in INR levels, making it essential for clients to maintain a consistent intake.
C. Whole milk: Whole milk contains minimal vitamin K and does not significantly impact warfarin therapy. While it provides nutrients, it does not pose a risk for altering anticoagulation and does not require dietary restrictions for warfarin management.
D. Salami: Salami is high in sodium and fat but low in vitamin K, so it does not directly affect warfarin activity. While clients should monitor overall diet for cardiovascular health, salami intake does not necessitate strict control for anticoagulation purposes.
