A client is taking aspirin (ASA) and asks the nurse how long the anticoagulant effect of a single dose of aspirin can last. The nurse replies:

"The anticoagulant effect of a single dose of aspirin can last for as long as a month."

"The anticoagulant effect of a single dose of aspirin can last for as long as a day."

"The anticoagulant effect of a single dose of aspirin can last for as long as a week."

"The anticoagulant effect of a single dose of aspirin can last for as long as 12 hours."

Answer and Explanation

The Correct Answer is C

A. "The anticoagulant effect of a single dose of aspirin can last for as long as a month." This statement is incorrect. While aspirin has antiplatelet effects that inhibit blood clot formation, its duration of action is not as long as a month. Aspirin irreversibly inhibits the enzyme cyclooxygenase (COX), thereby inhibiting platelet aggregation. However, the effects on platelet function are not permanent, and platelets turnover within a few days, thus the anticoagulant effect of a single dose of aspirin typically lasts for a shorter duration.

B. "The anticoagulant effect of a single dose of aspirin can last for as long as a day." Aspirin's primary effect is on platelets, not directly on overall blood clotting. It inhibits the COX enzyme, reducing the production of thromboxane A2, a chemical that promotes platelet aggregation. The initial inhibition of platelet function is strongest within the first 24 hours after taking aspirin. However, the affected platelets remain dysfunctional for their entire lifespan (around 7-10 days).

C. "The anticoagulant effect of a single dose of aspirin can last for as long as a week." This statement is correct. Aspirin's effect on platelets is due to its irreversible inhibition of the COX enzyme. Platelets have a lifespan of about 7-10 days. Once a platelet is affected by aspirin, it cannot regain its function. As your body continuously produces new platelets, the overall antiplatelet effect gradually diminishes over time.

D. "The anticoagulant effect of a single dose of aspirin can last for as long as 12 hours."

Rationale: This statement is partially correct. The antiplatelet effect of aspirin does not typically last as short as 12 hours. While the peak inhibition of platelet function occurs within hours after administration, the duration of action is longer due to the irreversible inhibition of COX-1. However, stating that it lasts exactly 12 hours may not be entirely accurate for all individuals, as the duration of action can vary depending on factors such as individual metabolism and dose.

Correct Answer is D

Explanation

White Blood Cells (WBCs): WBCs are part of the immune system and play a role in fighting infections. However, they are not directly involved in hemostasis or clot formation.

Antibodies: Antibodies are proteins produced by the immune system to recognize and neutralize foreign substances (antigens). They do not directly participate in clot formation.

Red Blood Cells (RBCs): RBCs carry oxygen and carbon dioxide but are not directly involved in clotting. They do not adhere to the vessel wall during hemostasis.

Platelets: Platelets are small cell fragments in the blood. They clump together (aggregate) at the site of injury to form a temporary plug (platelet plug). Platelets adhere to the injured vessel wall and release chemicals that initiate clotting.

A. prayer B. yoga C. massage D. meditation E. ointments with a steroid base

Correct Answer is ["A","B","C","D"]

Explanation

A. Prayer: Prayer and meditation are practices that focus on the mind-body connection and can be used for relaxation, stress reduction, and promoting inner peace. These practices are often included in CAM approaches.

B. Yoga: Yoga combines physical postures, breathing exercises, and meditation. It can improve flexibility, strength, balance, and overall well-being, making it a popular CAM therapy.

C. Massage: Massage therapy involves manipulating the soft tissues of the body to promote relaxation, pain relief, and improved circulation. It's a widely used CAM therapy.

D. Meditation: Meditation involves focusing your attention and quieting the mind. It can promote relaxation, reduce stress, and improve emotional well-being, aligning with CAM principles.

E. Ointments with a steroid base: Steroid creams are medications typically prescribed by doctors for specific skin conditions. While some natural remedies might be used topically in CAM, ointments with a steroid base wouldn't be considered a CAM therapy itself.
