1. A patient with a clotting disorder is prescribed an anticoagulant and asks you to explain the purpose of anticoagulant therapy. What is your best response? a. Anticoagulants are used to lyse existing clots. b. Anticoagulants are used to increase the flow of blood. c. Anticoagulants are used to prevent new clot formation. d. Anticoagulants are used to thin the viscosity of the blood. ANS: C Anticoagulants are drugs that interfere with the clotting process, so they are used to reduce ex...

1. What is the main role of insulin in the body? a. Conversion of complex carbohydrates into glucose b. Movement of glucose from blood into the cells c. Prevention of kidney excretion of glucose d. Prevention of the formation off at cells ANS: B Many body cells have membranes that do not allow glucose to move into the cells to participate in metabolism. When insulin binds to membrane insulin receptors, the membranes become more open to glucose, allowing it to enter. DIF: Cognitive Level...
