The patient requests information on alternative treatments for her arthritis. The nurse provides the patient with information on which of the following supplements?

A. Trombin (Evithrom): Incorrect: Thrombin (also known as factor IIa) is not typically used as a hemostatic drug. It is involved in the final step of the coagulation cascade, converting fibrinogen to fibrin to form a stable clot. However, it is not administered directly as a medication.

B. Aminocaproic acid (Amicar): Aminocaproic acid is an antifibrinolytic agent commonly used to control bleeding. It works by inhibiting the breakdown of fibrin clots, thus promoting hemostasis. It is particularly useful in situations where excessive bleeding occurs due to impaired clot dissolution. However, tranexamic acid is generally considered more potent and has a longer-lasting effect, making it the preferred choice in many situations.

C. Aspirin: Incorrect: Aspirin is an antiplatelet medication that inhibits platelet aggregation. While it can reduce the risk of clot formation, it is not primarily used for controlling postoperative bleeding.

D. Tranexamic acid (Cyklokapron): Correct: Tranexamic acid is another antifibrinolytic agent that helps prevent excessive bleeding. It works by blocking the breakdown of fibrin clots. Tranexamic acid is commonly used in surgical settings to manage bleeding during and after procedures.

A. Most CAM therapies are not totally ineffective: While some CAM therapies may lack strong scientific evidence, it's not accurate to say they are all ineffective. Some CAM therapies may have benefits, but it's important to be aware of them to avoid interactions.

B. Not all CAM therapies are dangerous: Many CAM therapies are generally safe. However, some can interact with medications or have unforeseen side effects, so assessing use is crucial.

C. Additional treatment may still be needed: Even if a patient uses CAM, they might still require conventional medical treatment. Assessing CAM use helps ensure a complete picture of the patient's healthcare regimen.

D. CAM therapies could interact with prescription and OTC medications. Correct. The primary reason to assess CAM use is to identify potential interactions with medications, potentially improving patient safety and treatment effectiveness.
