The patient has been started on warfarin (Coumadin) for deep vein thrombosis. The patient asks when the medication will break up the clots. The nurse's best response would be:

"This medication will not break down clots but will make it less likely that the clot will get larger."

"It will break down the clot within 8 to 12 hours of administration."

"It will take 7 to 10 days for the clot to break down."

"You will need to be on this medication for a long time before it will break down the clot."

Answer and Explanation

The Correct Answer is A

A. "This medication will not break down clots but will make it less likely that the clot will get larger." Warfarin (Coumadin) is an anticoagulant medication that works by inhibiting the synthesis of certain clotting factors in the liver. It does not directly break down existing clots but prevents the formation of new clots and the extension of existing ones. This response provides accurate information about the mechanism of action of warfarin.

B. "It will break down the clot within 8 to 12 hours of administration." This statement is incorrect. Warfarin does not have an immediate effect on existing clots. Its action is primarily preventive, reducing the risk of further clot formation and allowing the body's natural processes to gradually break down existing clots over time.

C. "It will take 7 to 10 days for the clot to break down." While the body's natural processes may start breaking down the clot within this timeframe, warfarin itself does not directly cause the dissolution of clots. This response is partially accurate in terms of the timeline for the body's natural clot resolution but does not specify that warfarin itself is not responsible for clot breakdown.

D. "You will need to be on this medication for a long time before it will break down the clot." This statement is misleading. Warfarin's role is to prevent the formation of new clots and further extension of existing ones rather than directly breaking down clots. Additionally, the duration of warfarin therapy is typically determined based on the individual's risk factors for clot formation, and it may not necessarily correlate with the time it takes for existing clots to resolve.

Correct Answer is C

Explanation

A. To prevent overuse of prescription medications: While some patients may use herbal therapies as an alternative to avoid overuse of prescription medications, this is not the primary reason for the widespread use of herbal therapies. People often turn to herbal remedies for their perceived natural benefits and to complement conventional treatments, rather than to prevent overuse.

B. Because herbal therapies are so much safer than manmade drugs: This is a common misconception. Herbal therapies are not necessarily safer than prescription drugs. They can have potent effects and interact with medications, potentially causing adverse reactions. The safety of herbal remedies varies widely depending on the specific herb and its use.

C. To increase feelings of wellness and promote holistic treatment: Many patients use herbal therapies as part of a holistic approach to health. They seek to improve overall wellness, balance, and harmony in their body, mind, and spirit. Herbal therapies are often integrated into a lifestyle that values natural and preventive health measures.

D. Because herbal therapies are much more regulated than prescription drugs: This statement is incorrect. Herbal therapies are generally less regulated than prescription drugs. In many countries, herbal supplements are not subject to the same rigorous testing and approval processes as prescription medications, leading to variability in quality and potency.

A. Food, Drug and Cosmetic Act B. Joint Commission on the Accreditation of Healthcare Organizations C. Health and Human Services (HHS) D. Dietary Supplement Health and Education Act (DSHEA)

Correct Answer is D

Explanation

A. Food, Drug and Cosmetic Act (FD&C Act): This act sets the groundwork for food and drug regulations, but it's not the specific legislation governing dietary supplements. While FD&C Act applies to some aspects of supplements, DSHEA has more specific regulations.

B. Joint Commission on the Accreditation of Healthcare Organizations (JCAHO): This organization focuses on accrediting healthcare facilities, not regulating supplements.

C. Health and Human Services (HHS): HHS is a broad department encompassing various healthcare agencies, but DSHEA is the specific act within HHS that governs supplements.

D. Dietary Supplement Health and Education Act (DSHEA): This 1994 act specifically addresses dietary supplements, outlining regulations for labeling, manufacturing, and marketing. It places the responsibility for ensuring the safety and effectiveness of supplements on the manufacturers, unlike prescription drugs approved by the FDA.
